%, % and 3^ longer than wide; sixth not wider but shorter, }£ longer than 

 wide; seventh and eighth equal in width, nearly '% thicker, obtrapezoidal in 

 basal % , as long as wide and a little shorter respectively ; ninth and tenth sub- 

 similar, obtrapezoidal, more than % and nearly 3^ thicker than the eighth, % 

 and }4 wider than long; eleventh unusually short, only 3^ longer than the 

 tenth and fully as wide, obliquely ogival in apical half. Prothorax relatively 

 small, scarcely as long as wide, barely }£ wider than the head, prominent and 

 narrowly rounded laterally at apical third, the sides thence rather feebly con- 

 vergent and very broadly sinuate to the base; surface with a continuous chain 

 of irregular sculpture transversely near the base, flexed slightly forward at the 

 sides. Scutellum distinct, nearly as wide as long, ogival. Elytra nearly 

 3^ longer than wide, almost three times as long as the prothorax and twice as 

 wide, almost evenly elliptical, only just visibly wider at basal %; subhumeral 

 impression rather distinct but small, transverse and deep along the basal 

 margin ; inner fovea large and deep ; suture not modified, the impressions obso- 

 lete. Legs slender, the anterior femora rather strongly, the four posterior feebly, 

 clavate. Length 1.2-1.4 mm.; width 0.6-0.68 mm. 



California (Siskiyou, Humboldt, Sonoma and !N"evada Cos.). 



This is a very abundant species in the northern and hilly parts 

 of California, probably extendin_^ in its range much further to 

 the northward. The description is drawn from the male, in which 

 sex the anterior femora are a little more strongly clavate, the thick- 

 ened portion rather stronglj rounded but not angulate and at a 

 point much nearer the apex than in the eastern species, with the 

 apical slope very rapid and feebly granulato-serrulate. The fe- 

 male differs scarcely at all in antennal structure, but has the 

 elj'tra a little more inflated. There is but little similarity between 

 this species and sparsus, it being much larger, more ventricose 

 and much more sti'ongly sculptured.

 Lee. : i. litt. 



Moderately stout and rather feebly ventricose, polished, im- 

 punctate anteriorly, the el^ytra sparsely and quite finely punctate ; 

 body piceous-black, the elytra paler, dark testaceous ; legs and 

 antennae pale ; pubescence rather sparse and short anteriorly, 

 long, suberect,pale and conspicuous on the elj'tra. Head slightly 

 transverse, the eyes moderate in size and prominence, only 

 slightly longer than the tempora. Antenufe about ^ as long as 

 the body, gradually and moderately incrassate toward tip ; joints 

 three to five distinctlj^ longer than wide and subequal, the sixth 

 shorter and only slightly elongate; seventh and eighth distinctly 

 thicker, subequal and fully as long as wide; ninth and tenth ob-
