Coleopterological Notices, V. 411 



On the disk of the pronotum two very broad feeble parallel im- 

 pressions can be discerned behind the middle, which unite with the 

 transverse subbasal fovea ; these impressions are analogous to those 

 of Anthophagus alpestris Heer, and perliaps some other species ; 

 here, however, the disk is very convex and resembles Orobanus in 

 outline, being not at all suggestive of Anthophagus in these re- 

 spects. ♦ 



G. llllltl'boldtianilS n. sp. — Depressed, highly polished, deep black ; 

 coxae and tarsi rufescent ; antennae black ; integuments strongly and sparsely 

 punctate, the abdomen minutely and densely so ; pubescence sparse, suberect, 

 uniform and coarse, moderately long, short subrecumbent and dense on the 

 abdomen. Head as wide as the prothorax, as wide as long, strongly constricted 

 at base, the constriction as usual extending sharply across the dorsal surface, 

 where it is broadly, anteriorly angulate ; surface with a deep depression in 

 mediau third between the eyes, limited laterally by oblique excavated lines, 

 arcuately impressed between the antennae, the epistoma impunctate ; ocelli 

 on a line with the posterior limits of the eyes distant by less than one-third of 

 the total width ; eyes well developed, convex and very prominent ; tempora 

 shorter, not at all prominent, convergent and arcuate ; antennae slender, fili- 

 form, nearly three-fifths as long as the body, the joints fully three times as 

 long as wide. Prothorax nearly as long as wide, the sides evenly rounded, 

 becoming convergent and sinuate posteriorly, subparallel in basal fourth ; base 

 truncate, rather wider than the apex ; disk widest at apical third, strongly, 

 evenly convex, impressed in the middle near the base. Elytra twice as long 

 as the prothorax, and, near the apex, twice as wide ; humeri rather broadly 

 exposed, rounded; sides straight and strongly divergent; humeral width 

 three-fourths of the subapical ; disk broadly, feebly impressed in the middle 

 toward base. Abdomen with nearly four exposed segments, shorter than the 

 elytra ; border wide, moderately inclined. Legs long and rather slender, 

 finely, densely pubescent ; posterior tarsi less than two-fifths as long as the 

 tibiae; claws long, slender, arcuate. Length 4.4 mm. ; width 1.65 mm. 



California (Humboldt Co.). 



The type is a male, having the sixth ventral short and broadly 

 emarginate throughout at apex, the median segment of the seventh 

 with a thin laminate carina in the middle toward base ; anterior 

 tarsi moderately dilated. I obtained the unique representative on 

 the under side of a small loose stone in the dry bed of a rivulet 

 near Fort Gaston, 



This species differs from temporalis in its smaller size, still sparser 

 and stronger punctuation, less prominent and more convergent tem- 

 pora, and in the very strong median lamina of the seventh ventral, 

 which is completely wanting in temporalis.
