genus Doter (see fig. 13). In classifying the wings of 
these insects, therefore, I consider dunbari , gracilis kan- 
sasensis and stenobasis, to be one species, which must be 
called minor Sellards by priority. Affinis and stigmatazans 
seem to comprise another species, chiefly distinguished 
from minor by the remoteness of 1A and Cu2; but these 
wings may be only the hind pair of the foregoing. By 
page precedence the name of the species must become 
affinis. Pusillus is removed all the other wings by its 
greater width.

Length of body, excluding cerci, 4 mm.; length of an- 
tennas, 3.5 mm.; length of cerci, 10 mm. Wing: length, 
7-8 mm. ; width, 2-3 mm. ; slender, subpetiolate, broadest 
beyond the middle; costal space narrow at base, widest 
opposite the point of divergence of Cul and Cu2; R + M 
straight at base, diverging upwards rather abruptly; Cul 
and Cu2 usually close together at base, diverging distally; 
1A fused with Cu at very base; pterostigma always pres- 
ent, but frequently only weakly preserved; cross-veins: 
one between R1 and R2 + 3 ; one between R3 + 4 and MA ; two 
between MA and MP; two between MP and Cu; two
