excessively finely and indistinctly so, tlie abdomen with a few scattered aspe- 

 rate punctures ; pubescence fine, rather dense but not conspicuous, longer and 

 sparse on tlie abdomen. Head very nearly as wide as the prothorax, wider 

 than long, the sides parallel ; eyes well developed, convex and prominent ; 

 antennse distinctly incrassate, short, barely as long as the head and prothorax, 

 the last joint as long as the two preceding. Prothorax one-third wider than 

 long, the sides just visibly convergent and almost straight from near the apex 

 to the rounded basal angles ; base arcuate ; disk broadly, feebly impressed 

 along the middle. Elytra fully as long as wide, not wider than the protho- 

 rax and one-half longer, parallel and straight at the sides ; humeri exposed. 

 Abdomen as long as the anterior parts, slightly narrower than the elytra, 

 parallel and straight at the sides, the border strong. Length 1.6 mm. ; 

 width 0.3 mm. 



New York. 



The middle spine of the sixth dorsal plate is as well developed as 

 in cuspidata, but is more inclined backward ; its apex is notched 

 anteriorly, the posterior spur more abruptly bent forward over the 

 tip than in cuapidata ; lateral spines small and distinct. The male 

 has, at the middle of the second tergite, two small tubercles distant 

 by one-half the width, on the third two rather stronger tubercles 

 distant by two-thirds the width, on the fourth two much feebler 

 tubercles distant by barely one-third the width, the fifth broadly 

 impressed in the middle. A single male. 



This species differs from cuspidata in its slightly more incrassate 

 antennae with longer terminal joint, in its wider and distinctly more 

 transverse prothorax, and in the position of the tubercles of the 

 fourth dorsal, which are distant by one-half the discal width in the 

 European species; also by the more posteriorly inclined terminal 

 spine, somewhat differently modified at apex, and in the entire 

 absence of the discal impression of the sixth segment at the base 

 of the spine. 



OLIGIJROTA n. gen. 



Body minute, parallel, subdepressed. Head large, quadrate, the 

 eyes moderate, convex and prominent, before the middle; infra- 

 lateral carina completely obsolete. Antennae short, incrassate, the 

 basal joint large, thick ; second shorter ; second and third strongly 

 constricted at base, the former much the larger ; outer joints trans- 

 verse. Mentum very small, transversely trapezoidal. Ligula 

 with a minute, apparently simple terminal process and two stiff 

 bristles, the palpi well developed, three-jointed, the first thick, elon-
