apex with coarse yellowish setae along the edge, the apex extending immedi- 

 ately above the truncate apical margin of the clypeus, the latter with a double 

 concave apex. Antennse )-^ as long as the body, moderately stout, the basal 

 joint nearly twice as long as wide, slightly swollen beneath toward base ; 

 second longer than wide, as long as the third and thicker ; three to seven sub- 

 similar, feebly obconic and longer than wide, the eighth of equal thickness but 

 not quite as long as wide ; ninth distinctly thicker, not quite as long as wide, 

 the tenth still thicker, obtrapezoidal, about as long as wide, with a deep in- 

 ternal excavation toward tip, the eleventh very long, somewhat' bent, nearly 

 as long as the preceding four combined, the base oblique and prolonged in- 

 ternally in a long posteriorly oblique corneous process, which is receivable in the 

 large excavation of the tenth joint. Prothorax not quite as long aa wide, 

 wildest and prominently rounded at the sides only very slightly before the 

 middle, the sides convergent and sinuate thence to the base, rounded anteriorly; 

 disk very convex, with three lar^ e nude fovege, the median slightly the smallest, 

 and two feeble spiniform protuberances all in a transverse line near the base, 

 the fovese not connected, the lateral prolonged forward in feeble, gradually 

 evanescent depressions, the median in a deep abrupt groove not extending quite 

 to the apex, the spines in fine short longitudinal carinas. Elytra almost as long 

 as wide, }4. longer than the prothorax and nearly twice as wide, the sides 

 divergent and strongly, evenly arcuate from base to apex, the humeral plica 

 large but short and not very prominent, not spinose ; surface convex ; discal 

 impression moderate, rapidly evanescent, the three basal foveae deep, puncti- 

 form and equal. Abdomen convex, shorter and narrower than the elytra, the 

 basal carinae stout, rapidly acuminate, more than }4 as long as the segment and 

 separated by a little less than % of the discal width. Fygidium simple, smooth, 

 feebly convex, circularly rounded, ^5 wider than long. Legs moderately long, 

 the middle and hind trochanters finely spiniform at tip ; femora distinctly 

 swollen beyond the middle, the anterior scarcely at all modified ; anterior 

 tibiae somewhat dilated and feebly excavated beneath toward tip, the anterior 

 tarsi slender and unmodified, fully % as long as the tibiae, with the second and 

 third joints equal ; apical appendage of the hind tibiae rather short, straight 

 and acuminate. Length 1.7 mm. ; width 0.65 mm. 



New York City and vicinity. 



The ventral characters of the male type, described above, are 

 exceedingly feeble, the last segment being moderately large, with 

 the surface evenly and feebly convex transversely and wholly un- 

 modified. The female differs but little in general form or size, the 

 head being less obviously wider than the prothorax, with the an- 

 tennae shorter and simple, the front rapidly declivous before the 

 antennae to the broadly angulate simple apex of the clypeus, the 

 declivous surface feebl}'^ tumid along the middle, the abdomen as 

 wide as the elytra and nearly as long and the pygidium similar to 

 that of the male. The terminal appendage of the hind tibiae
