wing easily. The aiiteuDas are short, slender, and terminated by 

 a small rounded mass composed of two joints. 



Tribe II.— KiXOPLllM. 



In this tribe the fourth joint of the tarsi is very small, and 

 rudimentary, forming merely a slight enlargement at the base of 

 the last joint; the pronotum is separated from the flanks (except 

 in Iclinea) by a more or less distinct elevated margin. The middle 

 coxae are prominent, conical, and contiguous in the first group, 

 but not prominent and slightly separate in the second, in v^diicb 

 too are found the only species which devour dead animal matter. 



Antennae with the external joints large, flattened, triangular. Enoplia. 

 Auteuuse with the last three joints lorniing a small club. Cokynetes. 



Group I. — Enoplia. 



The last joints of the antennae in these insects are flat, much 

 dilated and triangular, thus forming a serrate mass; in the male 

 the inner angle of the triangular joints is frequently prolonged 

 greatly. Finding that in Phyllobainus the pronotum is defined 

 by a distinct lateral line, it has been removed to the present 

 tribe, instead of constituting with it a group of the previous 

 tribe. The structure of the tarsi is also as in Enoplium, 

 the fourth joint being very small. Ichnea, with the tarsi and 

 antennae of this tribe and group, presents a thora.x having the 

 ])ronotum entirely continuous with the flanks, as in the preceding 

 tribe. 



A. Eyes emarginate internally ; 



Antennae 10-jointed,* club 3-jointed, not longer than the otber por- 

 tion. Phyllobaenus. 



AntennsB with intermediate joints indistinct and very short, club 

 3-jointed, with each joint as long as the basal part of the antennae. 



Ichnea. 



B. Eyes emarginate in front ; 



First joint of tarsi equal to the second, antennae 11-jointed ; 



Anterior tibife serrate externally. Chariessa, 



Anterior tibiae not serrate. Cregya, 



First joint of tarsi shorter than the second, inferior ; 



Eyes finely granulate, antennae 10-jointed. Enoplium. 



Eyes coarsely granulate, antennae 11-jointed. Orthopleura. 



* Lacordaire and Spinola both describe the antennae as 11-jointed ; 

 after examining several individuals, we lind the number of joints to be 

 only ten.
