Coleopterological Notices, VI. T19 



Some specimens have the abdomen, head and a feeble median 

 elvtral fascia darker. The male sexual characters seem to be very 

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

 broad, pale and coriaceous, fiat and broadly, feebly truncate at 

 apex. The large series before me displays but little variabilit}', 

 and the species nia}' be readil}^ known from nanus b}^ its larger 

 size and relativel}' much larger head. 



42. A. peiiinsulari§ n. sp. — ^loderately stout, convex, shiniug, pale 

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

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

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

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

 angles right and naiTowly rounded ; eyes rather large, prominent, much longer 

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

 tures coarse, sparse, scarcely closer and with smooth interspaces lateral] j'; an- 

 tenna; 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 and straight to the base; apex broadly, evenly 

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

 wide, not quite t^\ice as ■o'ide 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 ; onh' the tip of the copulatorj^ 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 closel}^ allied to nanus, but differs abundantly in 

 its somewhat larger size, denser pnnctuation, much larger ej^es, 

 more rectilinearly truncate head and relatively larger prothorax. 



43. A. iiyiiiplia n. sp. — -Shining, pale flavo-ferrugiuous throughout, mod- 

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

 tinct, of the pronotum shorter and more abundant, of the elytra suberect, 

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

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

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