angles obtusely rectangular, base feebly arcuate, the marginal line wanting, disc 

 convex, a postapical transverse impression at front angles, a small fovea at mid- 

 dle of declivity, surface coarsely not closely punctate, the sides absolutely smooth. 

 Elytra as broad at base as the thorax, broader behind, humeri distinct, but ob 

 tuse, strije not deep, the punctures rather small and not close, intervals flat, 

 smooth. Mesosternum opaque, finely alutaceous, not carinate between the coxse. 

 Metasteruum slightly rugose at sides. Abdomen indistinctly punctate. Poste- 

 rior femora stout with coarse, setigerous punctures near the knee, the tibise very 

 stout, the outer face with three oblique ridges, the upper two compo.sed of tuber- 

 cles, the lower prominent, spurs rather slender, but explanate toward end and 

 translucent at sides. Length .14-.20 inch ; 3.5-5 mm. 



While the usual color is piceous black, specimens occur with the 

 elytra brownish or even quite red. The hind tibiae are very broad, 

 although rather flat, the apex is fully half the length of the shorter 

 edge. The punctuation of the elytral striie seems variable, and in 

 many specimens the punctures are quite indistinct. This species will 

 be recognized as the most ventricose and massive among those in our 

 fauna. 



Occurs abundantly on the sea-coast of California south of San 

 Francisco. 



JE. spissipes Lee. — Oblong, subcylindrical, rufotestaceous, moderately 

 shining. Antennfe pale. Head convex, rather coarsely granulate and rugose. 

 Clypeus with narrow reflexcd border, subtruncate in front, sides arcuate, a slight 

 notch at the suture, gense not more prominent than the eyes. Thorax not quite 

 twice as wide as long, sides feebly arcuate, apex and base equal, hind angles 

 rounded, base arcuate, without distinct marginal line, disc moderately convex, 

 indistinctly rugoso-puuctate. Elytra as wide at base as the thorax, humeri dis- 

 tinct, but obtuse, surface deeply striate, strise indistinctly i)unctate, intervals 

 flat, the surface somewhat irregular. Mesosternum alutaceous. Metasteruum 

 at sides alutaceous, shining, a few scattered fine punctures. Abdomen coarsely 

 deeply and sparsely punctured. Anterior tibiae with two large teeth and a much 

 smaller one, above not crenate. Posterior femora oval, sparsely punctate, the 

 tibia stout, as broad at apex as half the length, the outer side without transverse 

 carina?, but with acute granules arranged in longitudinal series, the tibial simrs 

 short, stout and somewhat expanded at tip. Length .16-.18 inch ; 4-4.5 mm. 



Of this species three specimens have been seen, the type from 

 Marquette, Mich., agrees entirely with the above description, two 

 others from Lowell, Mass., are more slender, the clypeus more ob- 

 viously truncate and the abdomen with fewer j)unctures. The^e 

 characters are possibly merely variations or sexual, but more speci- 

 mens must be studied before this can be determined.
