NORTH AMERICAN COLEOPTERA. 245 



Species with distinct a'lieous surface lustre. 



Thorax closely punctate; impression distinct Siibcriilita. 



Species rufotestaceous ; legs always pale. 



Thorax moderately closely jiuuctate, the ante-basal impressions scarcely 

 visible parvula. 



E. fUMCiila Crotch. — Form ovate, rather robust, piceous, feebly shining. 

 Antennfe rufotestaceous, sometimes darker toward the apex. Front with a few 

 coarse and deep punctures. Thorax twice as wide as long, slightly narrowed in 

 front, sides moderately arcuate, anterior angles obliquely truncate, disc convex, 

 punctuation coarse, dense and deep, the ante-basal impressions feeble, being 

 almost obliterated by the punctuation. Elytra scarcely wider at base than the 

 thorax, humeri obtuse, umbone moderately prominent, disc regularly convex, 

 the strige of the middle slightly impressed and acute, round, not crowded punc- 

 tures, those at the sides deeper, with deep and closely placed punctures, intervals 

 near the suture distinctly wider than the striae and all with a single series of 

 minute punctures. Prosternum coarsely, not closely punctured. Abdomen 

 piceous, sparsely punctate and pubescent. Femora of all the legs piceous, tibiae 

 and tarsi rufotestaceous. Length .08 inch. ; 2 mm. 



This species is, as a rule, larger and more robust than cucumerls, 

 the thoracic punctuation so close, coarse and deep that it would be 

 called cribrate if in the same proportion on a larger insect and the 

 ante-basal impressions very feeble. 



Seems to be a widely distributed species over the entire country 

 east of the Mississippi, also in Missouri. 



E. lobata Crotch. — Ovate, of robust facies, piceous, feebly shining. An- 

 teunse rufotestaceous. Front smooth, a few coarse punctures near the eye. 

 Thorax twice as wide as long, slightly narrowed in front, sides nearly straight, 

 obliquely truncate at anterior angles, disc convex, the punctures coarse and deep, 

 round, not densely crowded, the intervals shining, the ante-basal impression 

 moderately deep, arcuate at middle toward the base, the longitudinal impressions 

 distinct. Elytra distinctly wider at base than the thorax, humeri rounded, 

 umbone distinct, disc rathei' deeply striate, the punctures coarse, deep, quadrate 

 and closely placed, the intervals very narrow and at the sides almost like acute 

 costte. each with a row of flue punctures. Prosternum coarsely, not closely 

 punctate. Abdomen brownish, sparsely punctate and pubescent. Legs rufotes- 

 taceous, the posterior femora piceous. Length .06— .08 inch.; 1.5— 2 mm. 



The species with fascala and cuciiineris are closely related. E. 

 lobata has a more closely punctate thorax than cucumerls, but much 

 less so than in fu.scala. The latter has the ante-basal impression 

 almost entii'ely obliterated. In lobata the elytral punctures are 

 denser, coarser and deeper than in either of the others. 



Occurs in North Carolina and Florida, N. Smyrna (Schwarz). 



E. ciK'uiiieris Harris. -Ovate, slightly oblong, piceous, shining. Antennte 

 rufotestaceous. Head smooth, rarely with a few punctures near the eye. Thorax 

 nearly twice as wide as long, slightly narrowed in front, anterior angles obliquely
