LIMNEPHIUDAE. 

 Type. M.c.7, 10,880. Col.: Ward (E. J. Oalar). 



In color markings and general appearance close to ( '. /» rpnsilhi.s. It dil 

 from that species in lacking a row of black spines on the from side of the trout 

 femora, and in that the first joint of the front tarsus in the male i> much 

 shorter than the second joint, in fact less than half as long, and mosl Important 

 in the shape of the male genital parts (Plate 7, fig. 101), which Been from tin- 

 side show no median projecting part which is characteristic of ('. perpusitt'U 

 ( >f the same size as that species. 



Zaporota, gen. nov. 



Related to Colpotaulius, hut the spurs 0, 2, 2, and the pronotum short. 



The male palpi are very short, t he second and third joints together scarcely 

 long as width of face from eye to eye; the front t ihia faintly curved in the male, 

 almost without spines except two close together at inner tip; front femora 

 with short dense hair beneath; legs with few spines, last joint of hind tarsus 

 with several distinct spines beneath; no ocellar macrochaetae; pronotum 

 short; bristles of mesonotum in well-defined strips. Venation of type usual 

 in family, fore wings with rounded tip, membrane not granulate; hind wings 

 scarcely incised at end of cubitus. 



In my table of the family (Can. out., 48, L916, p. 1 IS) it will run to 

 Allegophylax except that it has not a granulate membrane; it differs 

 in very short palpi, hare front tibia, and different shape of wings. 



Type. — Z. pattens, gen. nov. 



Zaporota pallkxs, sp. nov. 



Type.- M. C. Z. 10,878. Alaska: Demarkation Point, 30 June 

 (W. S. Brooks). 



Pale yellowish throughout, with yellowish hair; dorsum of abdomen dark, 

 spines of legs black, and sometimes some of the veins in middle of wings are 

 brownish. Fore wings with the first fork scarcely back of anastomosis, third 

 fork acute on anastomosis, second apical cell very wide at base, discal cell 

 much longer than the pedicel, radius barely curved at the stigma; in hind 

 wings the discal cell reaches barely in front of the cubital fork. In front 

 tarsus of the male the basal joint is as long as the second. 



Expanse 1-i to 16 mm.
