202 THE CANADIAN ENTOMOLOGIST. 



as the penultimate, lateral margins sloping, lateral angles slightly produced 

 and rounding, posterior margin with two rounding teeth on each side of 

 the deep median incision, the outer pair extending obliquely inwards, 

 twice as long as the inner pair; male valve less than half as long as the 

 ultimate segment, semicircular, plates twice the width of the valve, almost 

 semicircular, slightly elongate, the margin fringed with fine white hairs^ 

 four strong spines inside the margin on either side. 



Described from fourteen specimens from Wray and Fort Collins, 

 Colo., and Kimball, Neb. 



Phlepsius ciimiilatus, n. sp. — Intermediate in size and colour between 

 graphicus ^.n^ Slip er bus ^ lobate commissural line faint. Length 6.5 mm.; 

 width nearly 3 mm. 



Head narrower than the pronotum, vertex nearly parallel margined, 

 slightly sloping, passage to the front distinct but not angled, front broader 

 than in superbus and not as convex ; elytra broad and slightly compressed 

 behind, the iirorations finer and weaker than in graphicus. 



Colour : yellowish fulvous irrorate with a rich testaceous brown shad- 

 ing to fuscous where the irrorations are thickened up ; the anterior mar- 

 gin of vertex with a light line interrupted in the middle by a red point, 

 two fuscous points on the disc of the scutellum, the commissural line 

 faintly lobate ; below tawny yellow, the front heavily marked with brown- 

 ish fuscous, the rest of face and legs maculate. 



Genitalia : the ultimate ventral segment of the female two and one- 

 half times longer than the penultimate, cleft in the middle nearly to the 

 base by a triangular notch, either side of which there is another slight 

 notch ; from the outer lobe thus formed it rounds off to the base without 

 lateral angles ; male valve triangular, plates twice the length of the valve, 

 the sides roundingly angulate, the tips slightly angularly divergent, a dark 

 spot at the inner angle at the base, the margin fringed with fine hairs, the 

 submargin with a few white spines. 



Described from numerous specimens taken at Fort Collins, Virginia 

 Dale, Pinewood, and Livermore, Colo., all within the mountains, from the 

 first foothills up to 7,000 feet. 



Variety ardostaphylcBs n. var. — The preceding species was swept as 

 larvae and adults from Snowberry (Symphoricarpos sp.yl, where it was 

 found in abundance ; a little higher up on the mountains a few specimens, 

 along with their larvae, of a smaller and darker species were taken from
