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

 twice as wide as the prothorax, the sides parallel, feebly arcuate, becoming 

 straight near the base; apex almost evenly rounded; humeri narrowly rounded, 

 somewhat Inroad ly 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 ratlier longer than the remainder, 

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

 Length 1.6 mm.; width 0.65 mm. 



Wisconsin (Bayfield). Mr. H. F. Wickbam. 



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

 smaller eyes, longer tempora, longer antennjje 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 solely for 

 taxonomic reasons. 



TAlVirOTES n. gen. 



The members of this genus greatly resemble Vanonus 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 eyes 

 moderate in size, coarsely faceted, with very short -setse, which 

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

 from the base and minutely, feebly emarginate anteriorly. Epi- 

 stomal suture distinct, the epistoma narrow!}- coriaceous at apex, 

 and apparently with an adjacent terminal beaded segment which, 

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

 Vanonus. Antennae somewhat short, abruptl}' clavate, the club 

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

 Scutellum moderate, trapezoidal. Middle coxi\? 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 var3ing in length, the first three segments margined at 

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

 the hind femora completel}^ devoid of the papillose pad of Vano- 

 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 b}' the capitate antennae and toothed 

 hind femora ; they ma}^ be known as follows : —
