the middle ; humeral plica large, the subhumeral impression large and con- 

 spicuous ; basal fovese deep ; subsutural impressions narrow and strong, the 

 suture strongly beaded basally, the bead strongly expanded at base. Legs 

 long, the femora rather strongly and subequally clavate ; tarsi filiform, the 

 first four joints of the posterior decreasing moderately in length, with the first 

 distinctly longer than the second. Length 1.75-1.85 mm. ; width 0.8 mm.

The description is taken from the male, in which sex the third and 

 fourth ventral segments have each two similar discal teeth, sepa- 

 rated by a little less than half the entire width ; the teeth are short, 

 stout, inclined posteriori}^ and have their apices obliquely trun- 

 cate, the truncate surface black and finely and evenly rugose. 

 The female is very much more abundant than the male, and has the 

 elytra very slightly shorter, the antennae a little shorter and more 

 slender, with a less thickened club, and the femora perceptibly 

 less clavate. The posterior coxae are rather widely separated, the 

 metasternal edge between them broadly sinuate and acutely 

 prominent at the sides as usual.

Feebly ventricose, polished, impunctate, black, the elytra dark 

 rufous, sometimes slightly blackish toward tip ; legs and antennae 

 dark rufous or more obscure, the latter sometimes slightly 

 darker toward tip; pubescence very sparse on the head and 

 elytra, moderately long and suberect on the latter. Head rather 

 small, as long as wide, subparabolic behind, the eyes somewhat 

 small, anterior and not prominent ; clypeus simple. Antennae 

 slender, |- as long as the body, the club well differentiated but 

 narrow and parallel ; second joint distinctly narz'ower than the 

 first, much shorter but only slightly thicker than the next two, 

 subcylindric and fully twice as long as wide ; three to six equal 

 in width, elongate, feebly obconie ; third and fifth, and fourth and 

 sixth mutually subequal and about ^ and ^ longer than wide 

 respectively ; seventh a little thicker, feebly obconical and fully 

 f longer than wide ; eighth but little shorter than the seventh and 

 fully |- thicker, obovoidal, ^ longfer than wide ; ninth and tenth 

 just visibly thicker and equal, fully as long as wide; eleventh 

 much shorter than the two preceding and not distinctly thicker, 

 gradually pointed. Pro thorax barely as long as wide, narrowed
