antennae pale rufo-testaceous, the club quite distinctly blackish ; pubescence 

 nearly as in fatuus. ^earf rounded, as long as wide ; base of the occiput rather 

 more feebly arcuate than the sides of the tempora ; eyes rather well developed 

 and slightly prominent but anterior as usual. Antennse slender, fully as long 

 as the head and prothorax, the club very abrupt ; second joint as long as the 

 first and about as thick, very feebly obconic, distinctly longer than the next 

 two and much thicker, nearly twice as long as wide ; three to seven equal in 

 width ; third just visibly longer than wide ; fourth and sixth quadrate ; fifth 

 and seventh apparently a little thicker, % longer than wide and quadrate re- 

 spectively, slightly narrowed at base ; eighth fully }^ wider than the seventh, 

 nearly % wider than long ; ninth abruptly % wider, 34 wider than long, just 

 visibly narrower than the tenth, which is % wider than long ; eleventh not at 

 all thicker, not quite as long as the two preceding, very gradually, acutely and 

 obliquely pointed. Prothorax scarcely as long as wide, strongly convex, fully 

 34 wider than the head, subquadrate, rounded on the sides and narrowed at 

 base, strongly bifoveate and impressed near the base and bicarinate as in other 

 species of this subgenus. Elytra nearly % longer than wide, distinctly more 

 than twice as long as the prothorax and about %^ wider, oval, widest be- 

 fore the middle, the sides evenly and rather strongly arcuate to the base ■^ 

 humeral plica distinct, the impression moderate in size but elongate and very 

 deep ; fovese approximate ; subsutural impressions very narrow but distinct, 

 the suture finely but strongly beaded for a long distance from the base, the 

 bead abruptly though slightly expanded at the basal margin. Legs moderate, 

 the two anterior femora strongly, the other four feebly, clavate. Length 0.75 

 mm. ; width 0.32 mm. 



Michigan. 



This is the smallest species of the genus and holds strongly to 

 the fatuus type in its general organization; it hovpever differs in 

 its intense black color, antennal structure and in its much smaller 

 size. Two specimens. 



20. E. capitatus n. sp. — Somewhat stout, moderately ventricose, polished 

 and subimpunctate ; head black, the prothorax piceous, paler at apex, the 

 elytra pale rufo-testaceous throughout; legs and antennal club very pale, 

 luteous, the antennal funicle and base darker testaceous; pubescence nearly as 

 in fatuus. Head distinctly wider than long, circularly rounded behind the 

 eyes, which are rather small and scarcely at all prominent; antennal promi- 

 nences very feeble, widely separated; declivous front transversely tumid just 

 behind the clypeus as usual. Antennse as long as the head and prothorax, 

 slender, the club very strong and abrupt; second joint not as long as the first, 

 but fully as thick, very strongly obconic, % longer than wide, much longer and 

 thicker than the next two; three to seven equal in thickness, the fifth perhaps 

 a little thicker; third and seventh quadrate; fourth and sixth l^, the fifth 3^, 

 longer than wide; eighth fully % wider, transverse, % wider than long, 

 strongly conic in apical % ; ninth twice as long and nearly twice as wide a& 

 the eighth, feebly obtrapezoidal, more than ^ wider than long; tenth not in
