Elongate-oval, slender. Head, thorax, suture of elytra, and under sur- 

 face black; beak, antennae, legs, apex of thorax and elytra, except suture, 

 pale reddish-brown; above sparsely clothed with oblong white scales, con- 

 densed on sides of thorax and in irregular patches on sides of elytra, else- 

 where 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 towards apex; of female, half as long 

 as elytra, smooth, cylindrical, slightly scaly near base. Antenna- 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 trans- 

 versely rugose, their setfe almost invisible. Length 2 mm. 



A single male of this species, bearing the label "8. vest i 1 11.9 

 Lee. from Indiana," was donated us by Col. Casey. A comparison 

 with the Kansas type of i-estitus at Cambridge shows that species 

 to be much larger and more robust, with head, beak and thorax 

 wholly black, elytra dull reddish, scales large, close-set and evenly 

 distributed; thorax wider than long; elytra with distinct, coarse 

 inclined seta?. LeConte gives its form, color and vestiture as 

 "Rather robust, convex, black, very densely clothed with grayish 

 and yellowish, broadly oval scales ; antennse and legs ferruginous 

 brown." He states that the intervals are flat, each with a row 

 of whitish hairs and gives the length as 2.75 mm., all of which 

 characters agree with his type of vestitus. Three specimens of 

 caseyl, labelled cestitus by Dietz, are in the Cambridge collection. 

 Both Col. Casey and Dr. Dietz have misinterpreted LeConte's 

 species as neither one had the type before him when describing 

 the species they call rest it us, and Dietz (1804, 1(>0) criticises 

 LeConte for not describing the true res fit us correctly. 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 labelled as to lo- 

 cality as it is to name.
