terior margin nearly straight. Elytra nearly three-fourths longer than wide, 

 twice as wide as the prothorax, the sides parallel, feeblj' arcuate, becoming 

 straight near the base ; a^iex almost evenly rounded ; humeri narrowly rounded, 

 somewhat broadly exposed at base; disk scarcely at all impressed except be- 

 hind the scutellum, finely, densely punctate, the omoplates small and rather 

 feeble. Abdomen finely, somewhat sparsely punctate, the punctures slightly 

 elongate, finely pubescent, the first segment rather longer than the remainder, 

 the fourth about as long as the two preceding. Legs rather long and slender. 

 Length 1.6 mm.; width 0.65 mm. 



Wisconsin (Ba^'fielcl). Mr. H. F. Wickham. 



A small but veiy distinct species to be readily known b}- its 

 smaller eyes, longer tempora, longer antennae and completely 

 black legs. It is much more closely allied to piceus than to the 

 huronicus group, and is placed at the end of the genus solelj' for 

 taxonomic reasons. 



TANILOTES n. gen. 



The members of this genus greath' resemble Yanonus in gen- 

 eral form and habitus, and the sculpture and fine, even, decumbent 

 vestiture are exactly as in the piceus group of that genus. The 

 head is only very slightly wider than the prothorax, the ej'es 

 moderate in size, coarsely faceted, with very short setae, which 

 are much more evident in densus than in lacusfris, rather distant 

 from the base and minutel}', feebly emarginate anteriorly. Epi- 

 stomal suture distinct, the epistoma narrowh' coriaceous at apex, 

 and apparentl3' with an adjacent terminal beaded segment which, 

 however, may be a basal margin of the labrum. Palpi as in 

 Yanonus. Antennae somewhat short, abruptly clavate, the club 

 parallel and five-jointed. Pronotum biimpressed near the base. 

 Scutellum moderate, trapezoidal. Middle coxa? moderateh^ sepa- 

 rated, the posterior not more widely so. Abdomen with the basal 

 segment large, much more than equaling all the others combined, 

 the fourth var3^ing in length, the first three segments margined at 

 apex with a very wide pale and coriaceous border. Legs slender, 

 the hind femora completel}'^ devoid of the papillose pad of Yano- 

 nus, but having beneath near the apex, and in both sexes, a large 

 lamelliform tooth. 



Our two species mutually differ to a great degree, but are per- 

 fectly congeneric, as shown by the capitate antenna? and toothed 

 hind femora ; they may be known as follows : —
