LEIODINAE AND CATOPINAE ( COLEOPTERA ; LEIODIDAE ) FROM JAMAICA AND PUERTO RICO *

one Dissochaetus from Puerto Rico and one each from St. Vincent and Grenada; and three species of Proptomaphaginus, one from Puerto Rico and two from Cuba (Peck 197o). In the subfamily Leiodinae only three species are known: C:vrtusa conicitarsus Champion I925, from St. Vincent and Grenada; ztglyptinus guadelupensis Portevin I942, from Guadeloupe; and A. kazabi Hlisnikovsky 964, from Guadeloupe. Although Wolcott (936) mentions an Aglyptinus from Puerto Rico, it was intercepted in Inga laurina pods of unmentioned origin by Agriculture inspectors and may not be the native species.

Color dark brown, lighter on antennal base, legs, and anterior cen- ter o elytra.Eyes large.Antennae normal, reaching first /5 of elytra when laid back.Pronotum coarsely granulate; transverse, widest /3 rom base, 1.5 times as wide as.long; posterior angles obtuse.Elytra regularly rounded.Aedeagus (fig. ) elongate, drawn out at apex, shorter than parameres, no lateral hairs.Parameres thin, slightly enlarged and flattened at ends which curve to- ward each other, bearing 2 terminal setae.Internal sac armed, ligules absent.Genital segment (fig.2) complete, longer than broad, sternite lobes thin and curved; pleurite lobes thin, with a. few long setae.
Diagnosis and relationship.The species can easily be distinguished rom all others by the characters of the aedeagus and the genital segment.The species belongs to. the sl)inipes group o Jeannel (936) because of its major metatarsal spur which is longer than the first metatarsomere, and ot the characters of the aedeagus.This group contains the other known West Indian species of the genus.However, since the group is distributed through all the lands bordering the Caribbean Sea and the Gulf of Mexico, and the Dissochaetus fauna ot: most of this land is inadequately known, little about re- lationships or time or direction of migration can be said.
Collections and habitat data.Most of the specimens came from carrion-baited pitall traps set in the cloud forest of Hardwar Gap.This is a moist to wet forest at 4o00' elevation, set aside as a forest reserve by the Jamaican Forest Service.Big trees are present on level ground, but much of the forest has a somewhat reduced stat- ure.Epiphytes and tree erns are abundant.The litter appeared rich but was not sampled with Berlese unnels.The ollowing traps were set in various parts of this t:orest along a new road that was under construction, leading down to the north shore.T 309, along gully in dense ginger (Zingiberaceae) undergrowth, to males, 2 emales.T 3o, on edge of orested area in cluster o tree erns and ginger, 4 males, o emales.T 3 and T 32, hillside orest near stream, 2 males, 2 emales; 3 males, 3o emales.T 33 in midst o tree erns with heavy undergrowth, some logging present, soil 6F, male, 6 i:emales.T 34, dense orest, 3 males, emales.
The species was taken at three other sites: Trap 3o5 and 3o6, St. Andrews Parish, New Castle, 3o00' elev., a cool moist orested ravine between milepost 6 and 7, 6 males, 9 emales.In these collections, emales (95) were three times as abundant as males (3t).It may be that they are more attracted by the bait since it may be a potential oviposition site.This is a better rep- resentation o males than in Dissochaetus portoricensis Hatch where 5 males and 215 emales were collected (Peck 97o).
It is interesting to note in conclusio.nthat Jamaica is known to have only :his species o Catopinae, while each o the other two investigated Greater Antillean Islands (Cuba and Puerto Rico) have two species apiece.
The genus has 7 previously named species distributed rom south- ern Canada to Paraguay and southern Brasil.Hlisnikovsky (964 provides a thorough description o the genus, and a key to the species.
I have fo.und the named and new species difficult to distinguish by external eatures.Thus, my ollowing descriptions emphasize the aedeagus which I believe to be the most useful character complex in the genus or species discrimination.
Epipleuron often light in dark specimens.Eyes normal.Head, prothorax, and elytra with fine and scattered punctures, and hairs.
Diagnosis.The wing dimorphism and characters of the aedea- gus separate the species from others.
Variation.The aedeagus in some specimens is sometimes slightly broader in the middle and not quite so curved as illustrated in the lateral view.Wing dimorphism data are below.
The data show the species to be present in caves and forest litter at low and middle elevations.The cave populations are all short winged.Forest litter populations contain long and short winged males and females.The sample is inadequate to.compute the rela- tive frequency of short wings in the litter populations and any pos- sible relationship to sex.Wing dimorphism has not been noted for other members of the genus.The species is syntopic with the following, for both species were collected in Berlese sample 118, and a.t Corn Puss Gap.
Description.Length .I-.5 mm.Color piceous.Eyes and wings normal.Head, prothorax, and elytra with fine and scattered hairs and punctures.Aedeagus (fig.5) broad at base, gradually tapering and curving; in dorsal view (fig.6) tip broad and narrowing rapidly to apex.Parameres short, thin, bent at tips.
Diagnosis.The characters o.f the aedegus separate the species from all others.. Variation.In some specimens the aedeagus is narrower at the tip and narrower in the center in the lateral view than illustrated.There is, nevertheless, a clear gap in shape between this and the preceding species.
Habits.This and the preceding species are syntopic.This spe- cies was not found in caves or lowland forest litter.It may be more common in the higher elevation forests, where I did not extensively collect. 54.
Diagnosis.The cha.racters of the aedeagus separate the species from all others.
Habits.The species is undoubtedly more widely distributed in Puerto Rican forests and would be frequently found by using Berlese funnels, which I did not use in Puerto Rico.It was not iound in the II caves I visited.

Ps:l,che
[March-June this differs from the Scotocryptini which have a 3-3-3 formula.The species described below has a 3-3-3 formula (at least in the female, the male protarsal number is not known), which reinforces the sim- ilarity of the two groups.Because of the different formula of the new species, it will not key to the correct genus in Hatch (1929).
Description.The holotype male is missing its head and pro- notum.However, characters clearly defining the species are present on the thoracic and abdominal remnants.
Diagnosis.The species is geographically separated from the other two known species (hamatus Matthews of Mexico and Panama, and the bihamatus Matthews of Panama), and differs mor- phologically from the above in the characters of the male meso- and metafemora, and tarsal formula.
