E. rufida Mels.— Oblong oval, rufo-testaceous, moderately shining, sparsely 

 clothed with fulvous pubescence. Head densely and moderately coarsely punc- 

 tured. Antennse pale rufous, club slightly darker, joints proportioned as in 

 monoqnma. Thorax less than twice as wide as long, a little narrower at apex 

 than base, apex feebly emarginate, base very feebly sinuate on each side, side? 

 moderately arcuate, narrowed obliquely for a very short distance in front 

 of base but not sinuate, hind angles rectangular, margin moderately widely 

 explanate and very slightly reflexed, surface densely punctured. Elytra one- 

 half longer than wide, sides parallel in front, slightly arcuately narrowing at 

 apical third, margin narrowly reflexed, apex truncate, surface densely punctu- 

 late. Prothorax comparatively smooth beneath, body and abdomen densely 

 punctured. Femora sparsely punctulate. Intercoxal process acute. Length 

 .14— .16 inch ; 3.5—4 mm. 



The male has the sexual characters of the middle tibia better 

 marked than any other species in our fauna, the inward prolonga- 

 tion at the tip being so well developed as to be really a decided 

 deformity. 



The specimens before me have all been collected in Pennsylvania. 



K. coi'ticina Erichs.— Oblong oval, rufo-testaceous, disc of thorax and 

 elytra clouded with darker color, sparsely clothed with fulvous pubescence. 

 Head sparsely punctured, frontal impression divided, moderately deep. An- 

 tennse rufo-testaceous, club somewhat darker, structure as in monogama. 

 Thorax one-half wider than long, apex slightly narrower than base, sides 

 rather strongly arcuate, near the base sinuate, hind angles acute, slightly 

 prominent, margin narrowly reflexed, disc at middle piceo-rufous, surface 

 moderately densely punctulate. Elytra one-third longer than wide, sides 

 feebly arcuate and slightly narrower towards the tip which is truncate, 

 margin narrowly reflexed, surface moderately densely punctulate, disc clouded 

 with fuscous. Body beneath piceo-rufous, moderately punctulate. Legs paler, 

 femora sparsely punctulate. Intercoxal process triangular acute. Length .14 

 inch ; 3.5 mm. 



The middle tibife of the male are moderately strongly sinuate 

 within, and the apex prolonged inwards but less than in rufida. 



The elytra are usually clouded without any attempt at design, 

 some specimens however have the disc fuscous with a large oval 

 apical spot paler, a smaller near the humeri and also the suture and 

 margin paler. It has a superficial resemblance to immunda, but may 

 be known by the sexual characters. 

 Occurs especially in the Gulf States. 



E. iisaninnda Sturm. — Oblong oval, depressed, moderately shining, 

 sparsely pubescent, color variable. Head moderately densely punctured. 

 Antennse p;ile, club piceous, structure as in wtono^fawa. Thorax twice as wide 

 as long, narrower in front than base, apex feebly emarginate, base very feebly 

 sinuate on each side, sides moderately arcuate, posteriorly obliquely but very 

 feebly narrowed, hind angles rectangular, margin moderately explanate and 

 feebly reflexed, surface moderately densely punctured. Elytra one-fourth
