intermingled witii erect stiff setne. Head convex, subquadrate, 

 finely, remotely punctate, tbe ej'es moderate, not as long as the 

 tempora ; base broadly arcuato-truncate, not impressed; antenna' 

 a little longer than the head and prothorax, incrassate, the outer 

 joints as long as wide. Prothorax as long and wide as the head, 

 apparently a little longer than wide, rather strongly rounded at 

 the sides anteriorly, thence strongly oblique and straight to the 

 distinctly swollen basal margin ; disk evenly convex, finely and 

 sparsely punctate, the interspaces even and highly polished. 

 Elytra barely two-thirds longer than wide, about twice as wide as 

 the prothorax, scarcely one-third longer than the head and pro- 

 thorax combined, parallel, broadly-, obtusely rounded behind, the 

 humeri broadly exposed, transverse near the protliorax ; disk 

 very obsoletely impressed at the scutellum, coarsely and strongly 

 but not densel}' punctate. Abdomen minutely, densely punctate 

 and ])ubescent. Length 2.4 mm.; width 0.7 mm. 



California (Humboldt Co. to San Francisco). This is an 

 abundant species, represented by a large series in my cabinet. A 

 series of seven specimens, all that 1 obtained in the Hoopa Val- 

 ley, Humboldt Co., are pale ochreous-flavate throughout, other- 

 wise agreeing in every particular with the ordinary black form 

 which also seems to be very constant in coloration. 



In this section of the genus as represented by the present spe- 

 cies, the genital segment of the male is less elaborately modified 

 than in Icetus, the two lobes being flattened, gradually acuminate 

 and bent downward, the tips abruptly and minutely inflexed ; the 

 intromittent organ is very slender but shorter, feebl}^ swollen to- 

 ward apex and then gradually, finely acuminate and scarcely per- 

 ceptibly bent downward. 



(). \. ai'canilS n. sp. — Shiniiij;-, lilack, tlie elytra, legs ami l)asal parts of 

 the anteniiic dark red-brown; ])vibescence coarse, semi-erect, sparse but con- 

 spicuous. Jffdd quadrate, convex, truncate and impressed at base, finely, 

 sparsely punctate, the eyes rather small, much shorter than the tempora, the 

 latter parallel; antenna; moderately stout, about as long as the head and 

 prothorax, distinctly incrassate, the penultimate joints fully as long as wide. 

 Prothorax as long but scarcely as wide as the head, apparently a little hmger 

 than wide, rounded on the sides anteriorly, straiglit and obli(jue from anterior 

 third to the tumid basiil margin; disk convex, feebly impressed and with 

 .scratch-like sculpture in the middle toward l)ase, strongly evenly and not very 

 sjKirsely punctate. Elytni three-fourths longer than wide, very much h)nger 

 than the lu'ad and prothorax and about twice as wide as the latter, just visibly
