Color black, a small red spot on vertex, uniformly clothed with 

 short, very sparse, black, erect pubescence ; form rather short and 

 robust ; head subquadrate, a slight median impressed liile on occiput, 

 vertex transversely somewhat impressed, sparsely and mecliumly coarse- 

 ly punctured, the punctures being thickest just at vertex; labntin 

 obcordate; the anterior half rather thickly and coarsely punctured, the 

 posterior half impunctate, labro-clypeal suture distinct; clypeus short, 

 transverse oblong, anterior 1-3 impunctate, posterior 2-3 punctured 

 like labrum ; maxillary palpi short and stout, art. 2 long, 3 short, last 

 a little longer than 2, strongly flattened, truncate; antennae medium 

 in length, stout, art. i short, strongly swollen, 2 very small, beadlike, 

 3 longer than I, 4 as long as I, 4-10 subequal in length but gradually 

 increasing in diameter, last longer than 10 and strongly pencil-sharpen- 

 ed ; eyes small, far apart, slightly convex, very slightly notched. 



Pronotum subquadrate, sharply contracted in front, rather strongly 

 narrowed behind, posterior margin strongly everted, a deep longitud- 

 inal median impression extending almost its entire length, sparsely 

 punctured, the punctures like those of head ; scutellum small, rounded, 

 finely and thickly punctured; elytra 2*/ 2 times as long as joint width, 

 slightly widened posteriorly, ora distinct, 2 middle nervures visible, 

 finely and vermiculately rugose, a little more strongly marked toward 

 apices, separately rounded behind; ventral surface sparsely and finely 

 punctured ; legs long and stout ; femora and tibiae punctured like ven-

$ . Antennae longer and slenderer than 9 , pronotum convex and not 

 rugose, posterior tibial spurs long and slender, slightly trumpet-shaped. 



9 . Antennae shorter and stouter, pronotum slightly depressed and 

 slightly rugose, posterior tibial spurs shorter and stouter and strongly 

 trumpet-shaped.

Type in my collection. Type locality Humboldt County, Cali- 

 fornia. 



Distribution. Orleans Bar, Humboldt County, California, V. 

 22, n (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 blaisdclli'] and 

 by the much duller texture of the head and thorax and elytra.
