diameter from the lower margin of the head (in angusticollis usually 

 fully the short diameter away). The hairs on the legs are longer; 

 for example, on the upper surface of hind tibia there are v^arious hairs 

 whose length is fully one-half the diameter of the tibia, while in 

 angusticollis these hairs are less than one-half the diameter of the 

 tibia, (Fig. 4.) Both species have been taken wmged at the same 

 place on the same date— (Divide. Oregon, Sept. 12). I can not now 

 distinguish the soldiers ; some specimens 

 have the front margin of pronotum 

 emarginate in the middle. (Fig. 3, 1). 

 Occurs from western Nevada to Mon- 

 tana and through various places in Ore- 

 gon to British Columbia, and south to |* 

 Pacific Grove, California (fig. 5). f ^ 



TERMOPSIS LATICEPS Banks. 



Winged. — Castaneous; abdomen and 

 legs more yellowish. Wings pale gray, 

 with costal area yellowish, much paler 

 than in angusticollis. Structure similar 

 to angusticollis; the eyes are much larger, 

 being hardly one-half their short diam- 

 eter from lower margin of head (fig. la) ; 

 the antennae as long as head and pro- 

 notum, of 24 join ts. The proii otum has 

 the anterior corners more pointed than 

 in angusticollis. ^ Wings have the cos- ^^^ 5.-distribution of termopsis 

 tal area near tip less broad than in nevadensis. 



angusticollis, but toward base the veins are hardly as crowded together 

 as in that species; the radial sector has five to seven branches above. 

 The head as well as the rest of the body has long erect hairs above; 

 the tibia has spines about as in angusticollis. 



Length of winged adult 22 to 24 mm. ; width nearly 6 mm. 



Soldier. — Castaneous; abdomen and legs more yellow, head rather 

 reddish, mandibles mostly black. Head as broad behind as long, 

 broader behind than in front; mandibles toothed similar to angus- 

 ticollis; antennae rather longer than head, 23 joints, the joints, 

 especially toward base miuch longer than in angusticollis; pronotum 

 not twice as broad as long, anterior margin straight, the anterior 

 angles acute, sides sloping and rounded into the hind margin. Femora 

 not nearly as much swollen as in angusticollis. Body with only very 

 fine short hair. (Fig. 3, 2.) 



Length, 16 to 22 mm. 



Occurs in Arizona and New Mexico. Las Cruces, Dona Ana County, 

 New Mexico. In Arizona occurs at Douglas, Palmerlee, Garcia, and
