NEW PROTONEMURA (S. L.) FROM NEPAL PLECOPTERA; NEMOURIDAE) *

Described below are the stoneflies of the genus Protonemura (Nemouridae) collected in 967 by the Canadian Nepal Expedition organized by the Entomological Research Institute of the Canada Department of Agriculture in Ottawa. The genus Protonemura is understood here in its widest sense (sensu lato) as used by Kimmins 946, 95o) and Aubert 967) the genus is obviously in need of a revision as it contains a wide assemblage of forms some of which bear larval gills and some which do not. The species considered here are apparently gill-less as far as can be ascertained from the adults. The material examined comes from six localities: Godavari at altitudes of 5ooo ft and 6oo0 ft, Bhurunche at an altitude of 85o09500 ft, and four localities known only from their geographical coordinates and altitudes: 756N, 85ooE at 9900 ft and ooo ft, 2757’N, 8459E at ooo ft, 758N, 85oo E at xoo ft, and 28oo’N, 85oo’E at 9900 ft. Most of the specimens were collected in Malaise traps and therefore the collection dates indicate the period between visits to the traps. All the specimens are preserved in alcohol and are deposited in the Canadian National Collection of Insects in Ottawa. The drawings have been prepared from cleared specimens. Only the species represented by male specimens have been named, the others have been designated by letters to prevent useless uture synonymy.

Protonemura mira, n. sp. General coloration dark reddish brown; antennae black; anterior and lateral margins of pronotum light; wings uniformly brown; legs brown, tarsi and distal end o emora darkened; metaemora also with a subapical dark ring. Abdomen mostly membranous except for the genital segments and a pair of sclerotized tergal plates on each segment in the male. Genitalia reddish brown.  (1967, Fig. 99), but the subgenital plates are different.
Diagnosis" P. mira clearly belongs to the P. indica Kimmins group as defined by Aubert (I967); the shape of the process ot the paraprocts o the male and the subgenital plate as well as the vaginal structures ot: the female will easily separate mira rom the other known species of the group. Paraproct: median lamella short and pointed, heavily sclerotized; subanal plate wide, triangular, with broadly rounded angles; distal process forming a long curved trough-like appendage; external appendage finger-like, heavily sclerotized externally and bearing a subapical lateral tooth; the external appendage extends just beyond the subanal plate. Cerci long and membranous. Terga IX and X bearing small fields of spinules. Epiproct long and slender, its tip expanded laterally and bearing ventrally a short double row of heavy teeth.
Female genitalia: subgenital plate well sclerotized, prolonged posteriorly into a trapezoidal lobe which is broadly and regularly emarginate. Vaginal structures as in Figure 8.
Diagnosis: as the preceding species, P. godavariensis belongs to the P. indica group. The trough-like process of the subanal lobe of the male as well as the vaginal structures of the female are good diagnostic characters. The species is very close to P. assami Aubert and may eventually prove to be the same. Protonemura funicula, n. sp. General coloration brown; head and disk of pronotum dark brown. Wings clear, veins of the front wings marginated with brown. Legs banded: femora with a median and distal dark band, tibiae narrowly darkened at base and darkened again distally, tarsi dark. Abdomen mostly membranous except the genital segments; in the male a pair of small ventral sclerites and a pair of larger dorsal sclerites are borne at the base of each abdominal segment.
Male genitalia: sternum IX long with a short rounded median lobe; ventral vesicle large reaching three quarters of the length of the sternum. Paraproct: median lamella narrow; subanal plate partly membranous, irregularly triangular, prolonged distally into a heavily sclerotized process which is slightly recurred dorsally; this process is pointed apically and bears a sharp subterminal spine; ex-  (1967). The shape of the subanal lobes and the particularly long appendage of the epiproct are distinctive. Length of body omm, to tips of wings, 3-4 mm. General coloration dark brown; antennae and disk of pronotum nearly black. Wings amber, veins darker. Legs particularly the hind pair banded; femora with a median and a distal band. Abdomen membranous except the genital segments; in the male there is also a pair of small sclerites at the base of each tergum.
Male genitalia: sternum IX broadly pentagonal, prolonged into a long and tapering median lobe; this median lobe bears distally an apical expansion which is outturned at a right angle from the lobe and forms a beak-like extension ending in two sharp points. Paraproct: median lamella narrow and rounded apically; subanal plate sclerotized at base, divided distally into three lobes, the inner lobe short and rounded, the intermediate lobe membranous, and the outer lobe long and digitiform, fused laterally with the external appendage; external appendage fused with subanal lobe for most of its length, terminating distally in a beak-like point. Cerci long, membranous, and expanded slightly at tips. Tergum IX emarginate centrally, the emargination bearing short spinules. Tergum X excavated anteriorly, and prolonged into two short median lobes covered with spinules. Epiproct cylindrical, asymmetrical beyond middle, and terminating in a short curved lobe; a short irregular group of spinules .at base of epiproct.

Psyche [September-December
Male genitalia: sternum IX long and pentagonal; median lobe short and inconspicuous; ventral vesicle large. Paraproct: median lamella long, thin, and .extending backwards as far as the subanal plate; subanal plate terminating in two finger-like lobes, a shorter median lobe, and a larger lateral lobe; external appendage fused to lateral lobe ot: subanal plate and extending three quarters of its length. Tergum IX produced posteriorly into two asymmetrical lobes separated by a large median excavation; each lobe bears a distal patch of spines. Tergum X normal. Epiproct short and stocky, remarkably asymmetrical, and bearing a terminal whip-like appendage.
Female: unknown.  In general structure and coloration, this female agrees with P.
[unicula and P. adunca; it could be the female of either.
Female genitalia: the subgenital plate is very slightly trilobed. Vaginal structures as in Figure 18. Total length -2 ram, to tips of wings, 5-6 ram. Total length 15 mm, to tips of wings, 18 mm. General coloration dark brown. Wings blackish. Proand mesofemora light brown with an apical darkening, recta-femora brown with a subapical light ring. Total length 13 ram, to tips of wings, 16 ram.
