710 Coleojyterological Notices, VI. 



wide, convex; sides broadly rounded, obtusely constricted at basal fifth; 

 punctures close, strong and moderately fine. Elytra scarcely two-tbirds longer 

 than wide, distinctly more than twice as wide as the protborax, tbe sides 

 parallel and almost evenly arcuate ; apex not broadly rounded ; humeri broadly 

 exposed and transversely rounded at base; omoplates obsolete; punctures 

 coarse, deep and rather sparse, smaller toward apex. Abdomen somewhat 

 alutaceous, minutely and closety j)unctate, pubescent, paler at tip. Legs rather 

 long and slender. Length 2.7 mm. ; width 0.85 mm. 



California (Mendocino Co.). 



This conspicuous species bears a striking superficial resem- 

 blance to crihratus Lee, but belongs to the curvinus group, hav- 

 ing the head truncate at base. The single male before me has 

 ver}^ feeble sexual characters, and the spicule is not at all pro- 

 truded. 



28. A. seniiiiotatus n. sp. — Eather nari'ow, moderately depressed, shin- 

 ing, pale rufo-ferruginous, the under surface of the hind body blackish ex- 

 cept toward the abdominal apex; elytra each with a rounded and feebly de- 

 fined flavescent spot at apical fourth, the adjacent surface just visibly pices- 

 cent; pubescence short, moderately dense. Head well developed, quadrate, 

 as long as wide, feebly convex, finely, rather closely perforato-punctate, with 

 an ill-defined impunctate line; base truncate and unimpressed toward the 

 middle, the angles rounded ; tempora long, parallel, the eyes somewhat small 

 but prominent; antenniE short, rather slender, feebly incrassate, the tenth 

 joint not quite as long as wide. Prothorax quite distinctly narrower than the 

 head, as long as wide, formed nearly as in cercinus ; punctures fine and close. 

 Elytra two-thirds longer than wide, scarcely twice as vnAQ as the prothorax, 

 the sides parallel and broadly, evenly arcuate, the apex somewhat broadly and 

 transversely rounded; humeri rather widely exposed at base; scutellar im- 

 pression feeble; omoplates subobsolete; punctures close, deep and rather 

 small. Abdomen somewhat shining, the legs moderate in length, slender. 

 Length 2.25 mm. ; width 0.75 mm. 



California (Los Angeles Co.). 



A small species, represented b}' a single specimen of undeter- 

 mined sex, closely allied to cervinus, but differing in its more de- 

 pressed form, smaller size, rather smaller eyes, much shoi'ter and 

 more slender antennae and finer, closer punctures of the anterior 

 parts of the body. 



29. A. parallel ii!!i n. sp. — Subparallel and somewhat depressed, rather 

 dull, dark red-brown, the under surface throughout, legs and antennse rufo- 

 testaceous; head blackish; pubescence short, even, coarse, cinereous, dense and 

 conspicuous. Head subquadrate, about as long as wide, greatly narrowed be- 

 fore the rather small but i^rominent eyes, feebly convex, somewhat coar.sely.
