NORTH AMERICAN COLEOPTERA. 183 



alutaceoiis, sparsely moderately punctate ; scatellum blacu. Elytra a little 

 wider at base than the thorax, humeri very obtuse, umbone feebly prominent, 

 surface distinctly alutaceous, punctuation very indistinct, visible near base only. 

 Epipleurae black. Body beneath black. Abdomen at apex, and often at sides, 

 yellow; the surface shining, very sparsely punctate. Legs entirely black. 

 Length .24— .30 inch. ; 6—7.5 mm. 



This species resembles vlans, but is always more elongate, and the 

 elytra are almost entirely without the punctuation so evident even 

 in the smoothest forms of that species. The thorax is here always 

 completely black, both above and beneath and never so in vians. 

 The species seems to me abundantly distinct, although Crotch sup- 

 pressed the older name in making concinna a synonym of vians. 



Occurs in Georgia and Texas. 



6. <E. violasceilS Lee. — Form rather broadly oval and less convex, viola- 

 ceous blue, feebl.v shining. Antenufe short and stout, nearly black, third and 

 fourth joints equal. Head cribratel.v punctate at sides, smoother at middle of 

 occiput, tubercles obliterated, frontal carina very indistinct. Thorax twice as 

 wide at base as long, distinctly narrowed in front, sides feebly arcuate, front 

 angles slightly everted, disc moderately convex, surface shining, punctures sparse, 

 not deep, a I'ttle closer along the base and hind angles, these rather acute. Elytra 

 scarcely wider at base than the shorax, oval, broadest behind tlie middle, surface 

 coarsely and closely punctate as in the rougher forms of thoracica. Bod.v beneath 

 more shining than above, abdomen very sparsely and indistinctly punctate. 

 Length .24 inch. ; 6 mm. 



This species is rather more broadly oval than several in this part 

 of the series. The color is very nearly that of thoracica, and the 

 elytral sculpture rather coarser and deeper. The legs are entirely 

 blue-black. 



A specimen in my cabinet, from Nevada, which may be a variety 

 of the above, is slightly bronzed and with less pronounced sculpture. 



Two specimens from Fort Tejon, Cala. 



■7. <E. lugeiis Lee. — Oblong oval, feebly convex, dull black, opaque. An- 

 tennse shorter than half the body, third and fourth joints equal. Head ooarsely 

 and deepl.y punctured, densely between the eyes, frontal carina very short and 

 obtuse, tubercles very flat and indistinct. Thorax twice as wide as long, sides 

 arcuately narrowing to the front, margin very narrow, surface moderately closely 

 punctate, more coarsely near the sides El.ytra a little wider at base than the 

 thorax, humeri obtuse, umbone not distinct, surface opaque, very minutely alu- 

 taceous, without trace of punctuation. Body beneath and legs entirely black. 

 Abdomen shining, the punctuation coarse, but obsolete. Length .18 — .22 inch.
