Coleoi)terological Notices^ VI. *719 



Some specimens have the abdomen, head and a feeble median 

 elj'tral fascia darker. The male sexual characters seem to be very 

 feeble, the fifth ventral unmodified, the genital segment short, 

 broad, pale and coriaceous, flat and broadly, feebh'^ truncate at 

 apex. The large series before me displaj^s but little variability, 

 and the species may be readily known from nanus by its larger 

 size and relativel}^ much larger head. 



42. A. i>eiiiiisillari$ n. sp. — ^Moderately stout, convex, shining, pale 

 flavo-ferruginous throughout, the abdomen piceous; pubescence pale, moder- 

 ately long and abundant, subrecumbent. Head small, siibquadrate, slightly 

 wider than long, transversely truncate and rectilinear at base throughout the 

 width, with a feeble median impression on the vertical base of tlie occiput; 

 angles right and narrowly rounded ; eyes leather large, prominent, much longer 

 than the temiwra, the latter parallel, less prominent and rectilinear; punc- 

 tures coarse, sparse, scarcely closer and with smooth interspaces laterally; an- 

 tennae as long as the head and prothorax, very feebly and gradually incrassate, 

 the tenth joint subquadrate. Prothorax rather large, fully as wide as the 

 head, not quite as long as wide, narrowly and subangularly rounded at apical 

 fifth, the sides thence oblique an(,l straight to the base; apex broadly, evenly 

 arcuate, punctures strong and not very close-set. Elytra two-thirds longer than 

 wide, not quite twice as wide as the prothorax, the sides parallel, sensibly and 

 almost evenly arcuate, the apex somewhat broadly rounded; humeri only 

 moderately exposed and broadly rounded; scutellar impression and omoplates 

 completely obsolete; punctures strong but not very coarse, close-set. Abdomen 

 finely, rather closely punctate and coarsely pubescent, the legs moderate in 

 length, slender. Length 1.8 mm.; width 0.7 mm. 



Lower California. 



The male has simple sexual characters, the fifth ventral being 

 unmodified, the genital segment short, coriaceous and subtrun- 

 cate at apex ; only the tip of the copulatory sheath is exposed in 

 the type, but this is stout and rather rapidly narrowed to an ob- 

 tuse ogival or parabolic point, the under surface deeply excavated 

 throughout the width to the apex. 



This species is closely allied to na?i!<s, but differs abundantl}- in 

 its somewhat lai-ger size, denser punctuation, much larger eyes, 

 more rectilinearly truncate head and relatively larger prothorax, 



43. A. nyinplia n. sp. — Shining, pale flavo-ferruginous throughout, mod- 

 erately convex; pubescence of the head very sparse but long, coarse and dis- 

 tinct, of the pvonotnm shorter and more al)undant, of the elytra suberect, 

 rather long, coarse and moderately dense. Jlead subquadrate, a little wider 

 than long, truncate at base, the angles right, scmiowhat narrowly rounded; 

 eyes rather large and convex, longer and more prominent than the tempora,
