34 MEMOIRS ON THE COLEOPTERA 



as a distinct genus. Although very poorly represented in our 

 collections, this is probably not so much because of rarity as it is 

 owing to their obscure coloration, the frequent coating of earthy 

 matter and the habit of feigning death very persistently. My 

 collection includes only three specimens, representing three different 

 species. The six species known may be denned as follows: 



Outline regularly oval in form 2 



Outline oblong-suboval, more parallel and subrectilinear at the sides 

 medially 4 



2 Elytra with many small distinct spots of condensed silvery scale-like 

 pubescence. Oval, attenuated before and behind, convex, black, 

 fusco-squamulate, hispid with erect blackish-piceous bristles, which 

 are shorter and less numerous than usual; head and prothorax densely 

 punctate, the latter more coarsely and densely than in echinata; 

 elytra with fine striae, the sutural posteriorly and the external deep. 

 Length 2.75 mm. Washington State, Ulke. One specimen. [Syn- 

 calypta albonotata Lee., Proc. Acad. Phila., 1861, p. 344]. 



albonotata Lee. 



Elytra diffusely variegated with larger, more irregular patches of pale 

 squamiform decumbent hairs 3 



3 Form broadly oval, pointed behind, convex, rather shining, the con- 

 densed patches of paler squamiform pubescence more distinct 

 posteriorly, black, the erect bristles long, blackish and numerous; 

 head and prothorax rather coarsely, moderately closely punctate, 

 the elytra not longer than wide, rather acutely rounded and feebly 

 lobate at apex, the strife faintly impressed, obsolete and formed of 

 series of widely spaced punctures except posteriorly and laterally, 

 converging toward the more impressed sutural posteriorly as in 

 Simplocaria : surface finely, remotely punctate and shining; under 

 surface shining, with rather coarse, well spaced, perforate punctures 

 which are smaller on the duller abdomen. Length 2.3 mm.; width 

 i. 6 mm. District of Columbia. [Simplocaria stri go s a Mels., Proc. 

 Acad. Phila., 1844, p. 118 Georgia] strigosa Mels. 



Form more elongate, evenly oval, convex, black, dull in lustre, the erect 

 bristles long, claviform, numerous, seriate in arrangement; head and 

 prothorax with only moderately coarse, rather close-set punctures; 

 elytra fully a fifth longer than wide, the sides evenly rounded and 

 gradually converging posteriorly from near the middle, the apex 

 rather acute; surface closely, coarsely punctate-scabrous through- 

 out, the striae fine and distinct to the base, the sutural strong poste- 

 riorly, the others not so directed upon the sutural posteriorly as 

 in strigosa, the patches of denser squamiform decumbent hairs more 

 distinct and visible throughout though confused; under surface 

 duller, the punctures rather fine and close-set. Length 2.4 mm.; 

 width 1.6 mm. Lake Superior (Marquette and Eagle Harbor).
