"Antennae ii-jointed, filiform, rigid, inserted rather close together upon 

 the front ; the head tuberculate, stretched out forward and suddenly constricted 

 behind and attached to the thorax by a distinct neck ; thorax small, quadrate, 

 the side margins well defined ; presternum well defined with a slight point be- 

 hind fitting into the mesosternum ; elytra entire, with rows of large punctures 

 and intermediate ribs ; front coxae small, not prominent, their cavities trans- 

 verse, open behind ; mesosternum with the side pieces excavated for the middle 

 legs ; hind coxae transverse, flat, sulcate behind, receiving the thighs in repose ; 

 abdomen with five free ventral segments ; legs slender, contractile ; tibiae with- 

 out terminal spurs, tarsi s-jointed, spongy beneath, their claws simple." 



Gahan (26) has shown that the family should be further char- 

 acterized, as follows : 



A suture on each side of the prothorax between notum and the 

 pleurae; sternites and pleurae of the second abdominal segment com- 

 pletely fused with the third; wing venation of a more or less com- 

 pletely developed and unmodified state, the costa, subcosta, radius, 

 media, cubitus and analis present and joined together by a greater 

 number of transverse veins than are known to occur elsewhere in the 

 Coleoptera. The anterior branch of the media is a long vein running 

 uninterruptedly almost from the base to the margin and is joined by 

 means of two transverse veins with the media, and by two with the 

 posterior branch of the radius, which, itself, is joined to the radius 

 by two transverse veins. There are, also, two transverse veins be- 

 tween the cubitus and media, and two between the cubitus and analis. 



Key to the Genera of N. A. Cupedid.i;. 



Antennae less approximate at base, shorter and stouter, scarcely half as long as 

 the body ; eyes small ; gular sutures distant, curved slightly outwards ; double 

 row of spicula present only on posterior half of elytral margin. 



Priacma Lee. 



Antennae more approximate at base, longer, less stout, exceeding half length 

 of the body ; eyes larger ; gular sutures more approximate, not curved out- 

 wards, parallel or converging behind ; spicula, if present, occupying the full 

 length of the elytral margins Cupes Fabr. 



Key to the Species of Cupes. 



The following key is from Casey (13). 

 Supra-antennal tumid surface rounded and convex ; antennae shorter ; tem- 



pora more developed behind the eyes, which are usually smaller. 

 Body black, the head pale and ochreous-yellow in color; punctures of the 



elytral series very large, deep and quadrate capitatUS Fabr.
