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

 a small rounded mass composed of two joints. 



Tribe II.— E1VOPL.IEVI. 



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

 dimentary, forming merely a slight enlargement at the base of the 

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

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

 coxa? are prominent, conical, and contiguous in the first group, 

 but not prominent and slightly separate in the second, in which 

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



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

 Antennae with the last three joints forming a small club. Coeynetes. 



Group I. — Enoplia. 



The last joints of the antenna? 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 Phyllobaenus the pronotum is defined 

 by a distinct lateral line, I have been obliged to remove it to the 

 present tribe, instead of constituting with it a group of the pre- 

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

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

 antennas of this tribe and group, presents a thorax having the 

 pronotum entirely continuous with the flanks, as in the preceding 

 tribe. 



A. Eyes emarginate internally ; 



Antennae 10-jointed,* club 3-jointed, not longer than tbe other portion. 



Phyllobjencs. 

 Antennae 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 tibiae serrate externally. Chaeiessa. 



Anterior tibiae not serrate. Cregya. 



First joint of tarsi shorter than the second, inferior ; 



Eyes finely granulate, antennae 10-jointed. Enopliom. 



Eyes coarsely granulate, antennae 11-jointed. Oethopleura. 



* Lacordaire and Ppinolahoth describe the antennae as 11-jointed ; I have, 

 after examining several individuals, found the number of joints to be only 

 ten.
