368 Goleopterological Notices, VII. 



at base, parallel and broadly rounded anteriorly, nearly ^ wider 

 than the head, the transverse impression and fovese deep. Elytra 

 1^ longer than wide, slightly more than twice as long as the 

 prothorax and nearly twice as wide, widest slightlj^ before the 

 middle, the sides rather strongly arcuate ; apex subacute ; hur 

 meral plica and impression rather strong and conspicuous ; fovese 

 deep and approximate ; subsutural impressions narrow and some- 

 what distinct, the strong subbasal bead rather rapidly expanded 

 at base. Legs rather long ; tarsi filiform and slender ; four 

 anterior femora strongly, the two posterior less markedly, 

 clavate. Length 1.5 mm.; width 0.55 mm. 



Massachusetts, Pennsylvania, Canada (Toronto), Michigan 

 (Detroit) and Lake Superior. A widely diffused species but ap- 

 parently not very common ; the bright red of the elytra mentioned 

 by Say is probably a character of slight immaturity, as most of 

 the examples before me have the elytra quite dark rufous or 

 piceous in color. 



The male from which the description is drawn has remarkable 

 abdominal characters, as in the case of the allied though much 

 larger ventralis. The third and fourth segments have each a 

 posteriorly inclined short thick sublamellate discal plate, occupy- 

 ing about ^ and ^ of their widths, respectively, each plate broadly 

 sinuate throughout its width at apex and terminating laterally in 

 subdentiform projections, the thick apices of the plates to the 

 extreme lateral tips densely paved with combs of excessively 

 minute thick and short spinules. The female does not differ 

 much in general form or structure, but the femora are a trifle less 

 clavate, and the antennae perhaps just visibly shorter. 



3. E. semirulber n. sp. — Moderately ventricose, polished, impunctate, 

 black, the elytra bright rufous, dusky behind ; legs piceous-black ; antennae 

 pale rufous, sometimes slightly dusky toward tip ; pubescence long, coarse, sub- 

 erect and sparse on the elytra, less sparse on the head, abundant, short and 

 stiff on the prothorax. Head orbicular, not quite as long as wide, the eyes 

 moderate in size and not prominent ; clypeus short and broad, convex and 

 simple. Antennae slender, nearly % as long as the body, the club rather well 

 differentiated and somewhat incrassate ; second joint nearly as long as the 

 first but much thinner, subcylindric, more than twice as long as wide, nearly 

 as long as the next two and distinctly thicker ; three to six equal in width, 

 feebly obconic ; third and fifth about %, the fourth and sixth nearly J^, 

 longer than wide ; seventh a little longer than the fifth, )-^ wider, suboval, 

 narrowed at base, % longer than wide ; eighth oval, % wider than the seventh 

 and a little shorter, fully }4 longer than wide ; ninth nearly ^4 thicker than
