excessively finely and indistinctly so, the abdomen witli a few scattered aspe- 

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

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

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

 antennae 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 forw^ard over the 

 tip than in cuspidata ; 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 cuspidat&. 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. 



OI.IGUROTA n. gen. 



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

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

 lateral carina completely obsolete. Antennee 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-
