broadly sinuate, broadly depressed above and with two deep 

 impressions, separated by a narrow longitudinal carina. An- 

 tenna* about ^ as long as the body, rather stout, the last four or 

 five joints constituting a parallel, moderately dilated club; first 

 joint cylindrical, twice as long as wide, not quite as long as the 

 next two and slightly thicker ; second only slightlj'- shorter, 

 feebly obconical, 4 longer than wide, more than twice as long as 

 the third and slightly thicker; third not quite as long as wide, 

 more rounded internallj^; fourth -f wider than the third, trans- 

 versely oval, ^ wider than long ; fifth f wider than the preceding, 

 obtusel}^ produced externally, nearly f wider than long, wider 

 than the succeeding two and as wide as eight to ten ; sixth parallel- 

 sided, almost as long as wide ; seventh obtrapezoidal, slightly 

 wider than the sixth, a little wider than long ; eight to ten slightly 

 wider than the seventh, subequal, distinctly transverse; eleventh 

 not wider, conoidal at apex, as long as the two preceding ; joints 

 one to three polished and sparsely setose, four to eleven finely 

 asperulate and densely clothed with short coarse hairs in addition 

 to the setae. Prothorax parallel, slightly longer than wide, ^ 

 M'ider than the head, broadly rounded at the sides anteriorly, 

 moderately constricted toward base ; surface carinate at each side 

 toward base, with a transverse impression near the base, stronger 

 toward the middle, where it is interrupted by a narrow abrupt 

 elevation not rising above the general surface ; at each side along 

 the lateral carinse there is an elongate foveiform impression. Scu- 

 tellum very small, slightly elongate. Elytra elongate-oval, fully 

 ^ longer than wide, 2^ times as long as the prothorax and twice as 

 wide, slightly wider and a little more rounded at the sides just 

 before the middle ; apex conjointly rounded; humeri obsolete, the 

 sides oblique to the base ; humeral plica long, acutely elevated, the 

 impression long and deep; inner fovea large and deep, its 

 impression large, becoming rapidly shallow posteriorly ; sub- 

 sutural impressions obsolete, the suture not beaded. Legs long, 



*As in nearly all clavicorn Coleoptera, the enlarged outer joints of the an- 

 tennae are not exactly circular in cross section, and the form of these joints 

 therefore varies with the point of view, sometimes very greatly. Throughout 

 the present revision the dimensions given refer to the broadest or compressed 

 side of the antenuse. Itishojjed that the considerable detail given will be 

 found valuable to some degree in identifying closely allied species, and will 

 not prove to be wholly unwarranted by reason of individual variation. As 

 far as I have been able to discover this variability is not pronounced.
