TttE CANADIAN ENTOMOLOGIST. 13 1 



'I'horax dark biown, piothoiacic lobes with slender curved light brown 

 scales ; mesonotum with slender curved scales, a distinct bare (dark) 

 median line, immediately laterad of which on either side is a broad stripe 

 of brigiit brown scales, then a light golden brown or ochraceous stripe 

 extending cephalad from the scutellum to nape, external to these on the 

 caudad half are the darker brown scales, and the lateral portion of the 

 dorsum is covered with the lighter brown scales ; scutellum dark, with 

 light brown or ochraceous scales, and long light bristles on the margin ; 

 pleura ashy-brown, with white scales ; metanotum dark brown. 



Abdomen dark, heavily and closely covered by flat ochraceous scales; 

 two tiny dark submedian points not large enough to call spots, and yet 

 very distinct, on all the segments but the first, which has a large bunch of 

 almost white scales and light hairs ; ventrally the abdomen is also covered 

 with ochraceous scales, but not so heavily as dorsallv- 



Legs: coxai and trochanters mostly light-scaled; femora dorsally 

 sprinkled with dark brown and ochraceous scales, darker toward the apex, 

 but the very apex white ; ventrad, caudad and cephalad aspects 

 ochraceous. Tibia? much like femora but darker, and on the hind legs 

 have a distinct dark apical band ; metatarsi on fore legs much like tibite, 

 and all the following joints missing; on mid legs also much like tibiae; 

 tarsal joints dark, the first and second with small ochraceous basal spots ; 

 on the hind legs the metatarsi are (piite dark but still slightly sprinkled 

 with light scales, and it and all the tarsal joints except the fourth are 

 heavily basally white-banded, the fourth dark ; all ungues uniserrate. 



Wings clear, mostly dark-scaled, especially near the costa, the sixth 

 long vein mostly dark, first submarginal a little longer and about half the 

 width of the second posterior cell, the stems in each case about two-thirds 

 the length of the cell : cross-veins nearly equal in length, the posterior 

 about its own length distant from the mid ; halteres mostly light, a little 

 darkened on the knobs. 



Length, 5-6 mm. 



Habitat, Boise Barracks, Idaho. Taken July. 



This evidently lies near G. Fletcherii, but the abdominal marking is 

 distinct, and the specimens of Fletcherii which I have seen do not show a 

 marked band on the hind metatarsi, nor a white band on the proboscis. 



Both species were collected by the Surgeon U. S. Army, on duty at 

 the respective places, but in one case the name was not sent in.
