Length, 1.3mm. Plate IX., Fig. 58. 
flead small, frontal margin arcuate, depressed in the mid- 
dle. Antenne not as long as the head and prothorax, first 
joint cylindrical, second oblong, rounded, as thick as the first, 
third to fifth smaller, nearly globular, the sixth slightly larger. 
Seventh and eighth smaller, globular, ninth, tenth, and eleventh 
forming a club half as long as all the others taken together. 
The ninth is obconical, double the length and thickness of the 
eighth, tenth of the same form, the last oval not acute at tip. 
These three terminal joints gradually increase in thickness, 
the eleventh being three times as thick as the ninth and as 
long as the preceding ones. /Prothorax as long as the head 
(including the eyes) is wide, and about one-sixth» broader, 
very convex, the lateral fovez not in quite full view from 
above. A/ytra one-half longer than the prothorax, nearly the 
same across the prominent shoulders, and the apical width 
exceeding by one-third the sutural length. Sutural lines 
parallel, discal lines deep near the base, fine behind, entire. 
slightly arcuate, convergent from the base to the tip. Addomen 
short, the basal segment one-fourth as long as wide, the 
Carine conspicuous, including nearly one-half of the segmental 
width. ¢ with the basal abdominal segment depressed later- 
ally next to the broad margin, elevated and broadly lobed 
posteriorly; in the middle of the posterior limit it is minutely 
foveate. Second dorsal depressed at base, with a large rather 
shallow semicircular fovea at middle, enclosing five deep per- 
forate dark punctures arranged in a semicircle, the center of 
which is occupied by a much larger dark fovea. The third 
segment shows only two small dark punctures. The last is 
roundly impressed and tuberculate at base. Legs short.
