oblong white scales, condensed on sides of thorax and in irregular 

 patches on sides of elytra, elsewhere very unevenly scattered ; under 

 surface densely clothed with larger, rounded, concave white scales. 

 Beak of male scarcely as long as head and thorax, feebly curved, 

 finely striate, scaly and densely punctate on basal half, naked 

 and more finely punctate toward apex; of female half as long as 

 elytra, smooth, cylindrical, slightly scaly near base. Antennae in 

 male inserted at apical third, second joint of funicle half the length 

 of first, scarcely longer than third; of female inserted behind the 

 middle, second joint as long as the next two. Thorax slightly 

 longer than wide, sides feebly rounded, disc slightly constricted 

 near apex, rather densely and finely punctate. Elytra one-half 

 wider and three times as long^as thorax, sides parallel to apical third, 

 then rapidly converging to a subacute apex; striae fine, indistinctly 

 punctate; intervals feebly convex, minutely transversely rugose, 

 their setae almost invisible. . Length' 2 mm. 



The range of caseyi {vestitus Casey and Dietz nee. LeConte) 

 is given as Kansas, Dakota, Colorado and Montana, and it is 

 possible that the specimen donated by Casey is as wrongly labeled 

 as to locality as it is to name. Named in honor of Col. T. L. Casey. 



The species recognized by Dietz and in part by Casey as the 

 Smicronyx corniculatus of Fahraeus,+ the type of which was from 

 Pennsylvania, agrees fairly well with the original description except 

 in the colour of the elytra, which was given as "nigra, griseo- 

 tomentosa, fusco-nebulosa." As with many other North American 

 species described in Schonherr's work, the types of which are now 

 in Stockholm and therefore difficult of access, there has been much 

 difference of opinion as to what form Fahrseus had in hand. In 

 the Cambridge collection are two species placed side by side, each 

 bearing the label ''corniculatus Fahr." in LeConte's writing. One 

 of these is what we now know as sculpticolUs, the other as apionides, 

 both described by Casey. It was probably from the former that 

 LeConte drew up the description (1876,173) in which he gave the 

 colour as "dark brown, not very densely clothed with narrow 

 small whitish and yellowish scales," and the thorax as "much
