l6o CASEY 



head and prothorax, obscurely bronzed, with black elevations, the under 

 surface somewhat brighter bronze; head similarly confusedly compres- 

 so-rugose and impressed along the middle, the eyes well developed but 

 only moderately convex; prothorax almost similar in form, \\ith the 

 interrupted sulcus as in bijoveata, the deep concavities and lateral 

 callous areas nearly similar, the depressions rather more evenly punc- 

 tate; scutellum small, opaque as usual; elytra scarcely wider than the 

 prothorax and nearly twice as long as wide, the converging sides pos- 

 teriorly becoming sinuate near the slightly prolonged apices, which 

 are rather broader than in the preceding, arcuately truncate; surface 

 with the series of coarse punctures more evident, though lost laterally, 

 the callous polished spots equally or even more numerous but more 

 irregular, the general surface decidedly more coarsely and confusedly 

 rugose and uneven; under surface (9) very coarsely rugose, the pro- 

 sternum densely, very coarsely sculptured and nearly flat; raetasternum 

 broadly concave, the first ventral narrowly sulcate, obsoletely so pos- 

 teriorly, the fifth ventral with the two deep notches more approximate 

 than in the preceding species and subspecies. Length 1 7.0-1 9.0 mm.; 

 width 6.25-6.9 mm. Colorado (Boulder Co.) to Montana.

II — Form narrower and more elongate than in the preceding species, 

 rather convex, not more than feebly shining, dark coppery-red with 

 black elevations above, brighter cupreous beneath; head coarsely, 

 densely punctato-rugose, longitudinally impressed centrally, with two 

 strong callous areas basally; eyes rather prominent; prothorax less 

 transverse than in bijoveata, three-fourths wider than long, the sides 

 prominent and rounded just before the middle, thence more converg- 

 ing and straighter to the apex and less converging and less sinuate bas- 

 ally than in that form, the surface similar but with the sculpture of the 

 lateral depressions finer; elytra but slightly wider than the prothorax, 

 fully twice as long as wide, very gradually and acutely attenuate pos- 

 teriorly, the sides barely becoming at all sinuate, the apices truncate 

 with rounded angles, the surface unusually finely, densely and evenly 

 punctato-cribrate, the series of coarse punctures evident almost through- 

 out, though deeper and more perforate suturally, the callous spots 

 oblong, rather less numerous and not so strongly elevated ; under sur- 

 face ( 9 ) nearly similar, the fifth ventral more acutely and gradually 

 attenuated, with the apical notches approximate, the separating ligula 

 narrow and parallel. Length 15.8 mm.; width 5.5 mm. Wisconsin 

 (Bayfield), — H. F. Wickham vvickhami n. sp. 



12 — Body moderately stout and convex, rather dull, black above, the ele- 

 vations and almost the entire sutural region polished, the under surface 

 more lustrous, rather bright cupreous throughout; head very coarsely, 

 confusedly rugose, with a central and finely divided pit, the eyes rather 

 small and scarcely at all prominent; j)rothorax four-fifths wider than 

 long, nearly as in bijoveata in form and sculpture, except that instead 

 of a median interruj)ted furrow, there is an anterior elongate and densely 

 punctate pit, then a flat and sparsely punctate surface which is grad-
