Lee. An. Lye. 5, 156. 



A very pretty little species found at San Diego, on the sea shore, and nearly 

 related to the preceding four species ; the head is densely and more finely 

 punctured, the frontal line very fine. The thorax is scarcely as wide as long, 

 slightly narrowed behind ; the basal margin is indistinct. The elytra are convex, 

 truncate at the base, with the humeral angles moderately rounded. The punc- 

 tures are denser and a little finer than in A. nanus. 



34. A. pubescens, nigro-fuscus, pul)e cinerea suberecta hispidus, capite 

 postice truncato, thoraceque subtiliter punctatis, hoc quadrato, postice vix 

 angustato, elytris parallelis convexis grosse punctatis, basi truncatis. Long. 12. 



Ferte, Anthic. 177. 



One specimen, New York. This species and the two following differ from 

 all the preceding, in the form of the elytra, which are convex, truncate at base, 

 and with the sides straight as far as the middle, parallel in the males, slightly 

 diverging in the females, with the base each side of the scutellum a little 

 elevated. The head of this species is wider than the thorax, the eyes large ; 

 the frontal line narrow ; the occiput impressed ; thorax almost square, rounded 

 anteriorly, scarcely narrowed behind, very finely and densely punctured. Elytra 

 twice as wide as the thorax, punctures coarse, not dense ; the feet and base of 

 the antennae are piceous. 



35. A. fulvipes, nigro-fuscus, brevius subtiliter pubescens, capite postice 

 truncato, parcius punctulato, thorace subtiliter confertissime punctulato, postice 

 subangustato, elytris parallelis, basi truncatis, grosse punctatis, antennis pedi- 

 busque rufis. Long. -1. 



Ferte Anthic. 177. 



Louisiana, Mr. Wapler. Smaller than the preceding, with which it agrees 

 pefectly in shape, except that the thorax is more distinctly narrowed behind. 

 The head is much less densely punctulate, and the occiput is not impressed. 

 The pubescence is very different, being fine, short and not all erect. 



This is very evidently La Ferte^s species, although he says that the thorax 

 is not margined at base. I fear this is an error, as of all the American species 

 I have examined, there is but a single one, A. coracinus Lee. in which the 

 marginal line is not to be discovered. 



36. A. corticalis, fusco-piceus, pube longa suberecta vestitus, capite tho- 

 raceque impunctatis, illo postice truncato, hoc trapezoideo, postice subangus- 

 tato, elytris basi truncatis, parallelis, convexis, grosse punctatis, pedibus rufis. 

 Long. '11. 



Lee. An. Lye. 5, 154. 



I found this species very abundant at the junction of the Colorado and Gila 

 rivers, under the bark of trees. It agrees accurately in form with the two pre- 

 ceding species, but the head and thorax are impunctured; there is no occipital 

 impression ; the thorax is scarcely longer than wide, and is but slightly narrowed 

 behind. '1 he antennae are fuscous, with the base testaceous. 



37. A. maritimus, pallidus, cinereo-pubescens, capite thoraceque subti- 

 lissime punctulatis, illo truncato, hoc longiusculo ovato, elytris subtilius punc- 

 tatis, murinis, ellipticis convexis, basi emarginatis. Long. '09. 



Lee. An. Lye. 5, 156, 



San Diego, under sea-weed. At once distinguished by the roundness and 

 convexity of the elytra, which have scarcely any humeral angles; the frontal 

 line is very fine ; the thorax is as wide as the head, regularly narrowed to the 

 base, which is scarcely perceptibly margined. A variety occurs with the 

 suture and base of the elytra pale. Ferte's figure of A. bignttatus 

 represents very well this insect ; the species resembling it from the Atlantic 

 coast of the United States (A. i c t e r i c u s Ferte,) I have not yet seen.
