narrowed behind, posterior margin strongly everted, a deep longitud- 
inal median impression extending almost its entire length, sparsely

finely and thickly punctured; elytra 2%4 times as long as joint width, 
slightly widened posteriorly, ora distinct, 2 middle nervures visible,

Type in my collection. Type locality Humboldt County, Cali- 
fornia. 
Distribution. Orleans Bar, Humboldt County, California, V. 
22, 11 (F. W. Nunenmacher). 
Nunenmacheri can be told from blaisdclli by its sulcate pro- 
notum, by its much thicker (twice as thickly) punctured head, 
by its rugose pronotum and by the posterior tibial spurs being 
very trumpet-shaped (they are only grooved in Dlaisdelli) and 
by the much duller texture of the head and thorax and elytra.
