AMERICAN COLEOPTERA. 95 



The genera of this tribe are as follows : 



Prosternum of moderate width not depressed between the coxse. 

 Claws toothed at base. 

 Tarsi slender, fourth joint smaller than the third and not prolonged 



beneath the fifth Ectopria. 



Tarsi slightly dilated, joints 2 — 3 — 4 feebly emarginate, the fourth slightly 



prolonged beneath the fifth Dicraiiopselaphas. 



Claws not toothed at base, tarsi very slender Etibria. 



Prosternum narrow depressed between the coxse. Claws slightly broader at 

 base. Tarsi as in Ectopria Acnens. 



ECTOPRIA Lee. 

 Head vertical, received in the thorax as far as the eyes which are 

 partly concealed. Eyes moderately prominent. Antennae half the 

 length of body, feebly serrate $ or moderately strongly serrate % . 

 Front narrowed by the insertion of the antennas, then broader in front. 

 Labrum transverse, concealing the mandibles. Mentum transverse, 

 narrowed in front, ligula with four slender processes, the inner pair 

 longer, labial palpi short, last joint triangular. Maxillary palpi slender 

 elongate, second joint as long as the next two united, third short, 

 fourth slender tip slightly oblique, truncate, chisel-shaped without 

 terminal appendages. Prosternum moderately long before the coxae, 

 prolonged between them and meeting the mesosternum. Anterior 

 coxae not more prominent than the prosternum. Mesosternum oblique 

 in front and broadly emarginate, the coxae more widely separated than 

 the anterior. Metasternum rather short, the episterna wide, epimera 

 small. Posterior coxae very narrow, not contiguous. Ventral seg- 

 ments subequal. Legs moderate, tibiae with minute spurs. Tarsi 

 slender, moderately elongate, not lobed, first and fifth joints equal and 

 as long as the three intermediate together. Claws (PI, I, fig. 8 g, h), 

 slender and simple at tip $ , or bifid at tip % , at base with a broad 

 tooth in both sexes. Body ovate, convex, winged. 



M<xle. — A^tennfe decidedly serrate, first joint conical, second very 

 small, third broadly triangular not longer than the fourth, joints 

 4 — 10 serrate or subpectinate, last joint elongate. Eyes large. (PI. I, 

 fig. 8 b). 



Female. — Antennae much less serrate than in the male, first two 

 joints similar to the male, joints 3 — 4 equal, each as long as the first 

 two and nearly to the fifth. and sixth, joints 5 — 11 subequal, feebly 

 serrate. Eyes smaller. (PI. I, fig. 8 a). 



This genus as will be seen by comparison possesses nearly all 

 the essential characters of Eiihria, but difi"ers in the form of the 

 claws and the absence of terminal appendages to the maxillary
