very feebly, evenly sinuate in circular arc, the angles just visibly obtuse and 

 quite distinctly rounded ; base truncate, the angles extremely obtuse and just 

 visibly rounded or blunt ; sides evenly, very strongly rounded in circular arc 

 from base to apex ; disk very much wider in the middle than at base, very 

 strongly convex longitudinally as well as transversely, rather coarsely, very 

 deeply and densely punctate, the punctures distinctly separated toward the 

 middle, the marginal bead extremely fine and feeble. Elytra oval, fully three 

 times as long as the prothorax and, in the middle, not very distinctly wider ; 

 sides parallel, broadly and distinctly arcuate ; apex broadly parabolic ; disk 

 with unimpressed and distant series of somewhat approximate and rather 

 deeply impressed punctures, confused near the apex where the punctures are 

 finer and the surface dull ; intervals finely, sparsely but distinctly punctate, 

 the punctures irregularly disposed but tending to a uniserate arrangement 

 laterally. Abdomen finely, sparsely but very distinctly punctured. Legs 

 moderate. Length 5.6-6.0 mm. ; width 2.2-2.4 mm. 



Arizona (Seligman and Caiion Cosnino). Mr. Wickham. 

 This species is quite distinct in its very obtuse basal angles of 

 the prothorax and strongly arcuate sides of the latter. 



E. crassicoriiis n. sp. — Oblong-elongate, broadly convex, parallel, 

 smooth but very dull, black, the legs and antennae dark rufous. Head nearly 

 as in obtusus. Prothorax fully three-fourths wider than long, the apex nearly 

 five- sixths as wide as the base, broadly and extremely feebly sinuate, the 

 angles right and very narrowly rounded ; base transversely truncate ; basal 

 angles acute, prominent and not at all rounded ; sides feebly arcuate and 

 convergent anteriorly, nearly straight and parallel posteriorly and distinctly 

 sinuate very near the base ; disk not very finely but deeply and very densely 

 punctate, the punctures generally separated by from once to twice their own 

 diameters, but becoming gradually extremely dense and crowded although not 

 exactly in contact in lateral third ; marginal bead very fine but distinct. 

 Elytra subequal in width to the prothorax and about three times as long ; 

 sides parallel and scarcely visibly arcuate posteriorly; apex narrowly rounded ; 

 disk punctured as in obttisus. Abdomen very finely and sparsely punctate, the 

 punctures becoming larger but not very coarse laterally. Legs nearly as in 

 obtusus. Length 6.0 mm. ; width 2.7 mm. 



California (Hoopa Valley, Humboldt Co.). 



This species in general appearance somewhat resembles obtusus, 

 but differs in its still duller and very opaque integuments, more 

 parallel and less arcuate sides and less strongly emarginate apex of 

 the prothorax, the latter being more transverse, rather more coarsely 

 and densely punctate and with the basal angles acute and slightly 

 everted ; the pronotum is less longitudinally convex, and the entire 

 body is more parallel.
