which he gives the name helvola, the other rit/a, the true form of 

 the latter being described as a new species. 



Occurs abundantly in the entire region east of the Rocky Mts. 



E. rnfa Say. — Oval, rufo-piceous, moderately shininir, sparsely pubescent. 

 Head moderately densely punctate. Antennse rufous, club darker, funicle as 

 in monogavm. Thorax rather more than twice as wide as long, very little 

 narrower at apex than at base, sides strongly arcuate, obliquely narrowed and 

 very feebly sinuate near the base, hind angles acute moderately prominent, 

 margin moderately explanate but not reflexed, basal margin sinuate on each 

 side, surface moderately densely punctate. Elytra oval, longer than wide, 

 sides feebly arcuate and slightly narrower to base, margin narrow and slightly 

 reflexed, surface irregular, densely punctate, apex rotundato-truncate. Body 

 beneath moderately densely punctate, more coarsely than the upper surface. 

 Intercoxal process of abdomen broad, truncate. Femora coarsely and densely 

 punctate. Length .12 — .14 inch; 3 — 3.5 mm. 



The sexual characters are as in helvola, the inner edge of the 

 middle tibia of the male being rather deeply sinuate and at apex 

 prolonged inwards. 



This species is often confounded with helvola in collections, from 

 which however it abundantly differs in its more oblong form and 

 longer elytra which are scarcely narrowed to tip and very narrowly 

 margined. It has in some cabinets the mss. name punctatus. The 

 determination of the synonym above has been made from a specimen 

 received directly from Mr. Reitter, who places it erroneously with 

 those species in which the intercoxal process is triangular, the hind 

 coxae being widely separated as in helvola, the process broad and 

 truncate. 



Occurs over a great extent of the Atlantic and Gulf region. 



E. Integra n. sp.— Oblong oval, rufo- testaceous, slightly shining, sparsely 

 clothed with fulvous pubescence. Head moderately densely punctate. An- 

 tennte pale rufous, club darker. Thorax rather less than twice as wide as long, 

 base wider than apex, sides moderately arcuate, near the base obliquely nar- 

 rowed and slightly sinuate, hind angles acute, moderately prominent, margin 

 moderately explanate, slightly reflexed, apex moderately emarginate, base 

 slightly sinuate on each side, surface moderately densely punctulate. Elytra 

 oblong oval, one-third longer than wide, sides feebly arcuate and slightly 

 narrowed to tip, margin narrowly reflexed, apices conjointly rounded, suture 

 slightly dehiscent at tip, surface moderately densely punctulate. Body beneath 

 and femora moderately densely punctulate. Intercoxal process of abdomen 

 triangular. Length .12 — .14 inch; 3 — 3.6 mm. 



The sexual characters of the male are as in the preceding species, 

 but the siuuation of the middle tibia of the male and the inward 

 prolongation of the tip are feeble. 



The form of the elytral tip, the absence of truncation, occurs in
