NORTH AMERICAN COLEOPTERA. 209 



distinctly arcuate throughout; angles broadly rounded; disk transversely and 

 rather strongly convex, impunctate, excessively minutely and obsoletely stri- 

 gose with a few setigerous punctures along the sides and base and four discal 

 punctures, one near each apical angle, and another just before and on either 

 side of the centre of the disk. Elytra at base very slightly narrower than the 

 prothorax; sides very feebly divergent, very feebly arcuate; together broadly 

 and distinctly sinuate behind; disk very feebly convex, slightly wider than 

 long, very slightly shorter than the pronotuin, evenly, not very coarsely, 

 deeply, moderately densely and asperately punctate; intervals extremely feebly 

 reticulate. Scutellum rather large, triangular, asperate. Abdomen long, 

 slender, at base nearly as wide as the elytra; apparently not capable of much 

 contraction; sides gradually convergent and nearly straight to the apex; bor- 

 der rather wide, deep, nearly vertical; surface rather convex, finely and 

 very densely punctate. Legs rather short and slender; first four joints of the 

 posterior tarsi decreasing rapidly in length, first subequal to the fifth. 

 Length 2.4 mm. 



California; (Monterey Co. 1). 



The single representative is probably a female; the an- 

 terior tarsi are slightly dilated; the seventh segment has 

 four long, setigerous, anal styles, but both the dorsal and 

 ventral plates of the sixth segment are broadly and evenly 

 arcuate at apex. 



It is related to piislo Lee., but differs in the arrangement 

 and number of the occipital punctures; these are one at the 

 middle of the upper margin of the eye and one below the 

 posterior margin of the eye between the latter and the in- 

 traocular ridge; at the base on the sides there are a few very 

 minute punctures, and a transverse row of large setigerous 

 punctures immediate!}' before the nuchal constriction ex- 

 tending across the head. 



The type specimen was found under pine bark early in 

 February near the town of Monterey. 



ABAB ACTUS Sharp. 



A. pallidiceps *>• sp. — Slender, rather depressed, piceous; head rufo- 

 Ustaceous; legs pale flavate; antennae opaque, pale flavo-testaceous; head 

 sometimes clouded in the middle of the disk; pubescence sparse throughout, 

 fine; integuments polished. Jlead distinctly longer than wide; post-ocular 

 portion slightly less than twice as wide as long, semicircularly rounded be-
