and the long fourth joint of the tafsi, the tooth of the claws is quite 

 short, and the erect scales of the elytra are striate. 



Var. atomus. — A small male specimen from Utah, in Mr. Ulke's 

 collection, presents some differences, which, with more material, may 

 prove this to be a distinct species. Beak longer, tapering from the 

 base, front not impressed, prothorax more deeply constricted behind 

 the apical margin, transverse impression in front more sharply 

 limited, a little more coarsely punctured. Elytra wider at the base, 

 alternate interspaces wider, squamiform pubescence semi-procumbent, 

 pale ochreous, arranged in single or double rows, posterior callus with 

 some quite distinct, acute tubercles. The large scales are more 

 pearly white ; an indistinct and interrupted sutural vitta. The 

 specimen has an altogether smoother, scarcely hirsute appearance. 



squamatus group. 



A small number of species comprise this group. They are char- 

 acterized by the 7-jointed funicle of the antennae, femora mutic and 

 claws simple ; they are of small size, and are distinguished as follows : 



Above shining, finely pubesceut with scattered larger scales. 



Scutellar spot of elongate, whitish scales antlioiiomoides. 



Scutellar spot and transverse fascia behind the middle of the elytra, of large, 



white oval scales squainatus. 



Above, densely scaly or coarsely pubescent. 

 Tarsi stouter, third joint broadly bilobed. lobes long, fourth joint not project- 

 ing more than the length of the third ; anterior margin of prothorax 

 emarginate, elytra without rows of acute gi-anules. PI. xiv, fig. 31. 

 Oblong, apical cusps of prothorax acute; no elytral spots, .oregonensis. 

 Oval, anterior cusps indistinct, elytra with oblique spot and posterior fascia 



of condensed scales wiculus. 



Tarsi long and slender, fourth joint of anterior tarsi i)rojecting more than the 

 length of the third ; anterior margin of prothorax entire. PL xiv, fig. 31a. 

 Larger, not shining above, scales large, intermixed with coarse i)ubescence. 



I>er!<iiniilis. 

 Smaller, shining, above thinly clothed with long, white hair. 



albopilosuliis. 



C aiillioiioni«i«le!«i n. sp. — Oval elliptic, black, anteniuv and legs rufo- 

 piceous, above, shining, very thinly clothed with fine, whitish ])ubesceuce with a 

 few suberect, whitish scales. Beak moderately slender, regularly and rather 

 strongly curved, cylindrical, glabrous, striate and punctured from the base to the 

 insertion of the antennae, more remotely punctured towards the apex ; antennae 

 rather stout, inserted a little beyond the middle ( % ), club ovoidal. Head flat- 

 tened, very coarsely punctured ; prothorax more than one-half wider than long, 

 one-third wider at the base than at the apex, convergently rounded on the sides, 

 constricted at the apex, ocular lobes distinct, lateral tubercles small, acute, dorsal
