mediately in front of the hind angle. Disc of thorax rather dcnf5ely but not 

 very coarsely punctured, color above and beneath yellowish ferruginous except 

 the middle third of the upper surface which is brownish. Elytra slightly 

 wider than the thorax, feebly convex, striate, strire punctured, intervals con- 

 vex, rucjosely punctured ; color brownish except humeral angles which arm 

 yellowish ferruginous. Body beneath more shining than the upper surfaeo 

 sparsely punctured and pubescent, pale yellowish ferruginous, abdomen and 

 prosternum somewhat darker. Epipleura; j'ellowish ferruginous. Legs palo 

 yellowish testaceous. Tarsi with first joint as long as the two following which 

 are not sublobed beneath, fourth joint small scarcely longer than half the third. 

 Length .42 inch; 10.5 mm. 



The antenna) of" this species are equal in length to about half that 

 of the entire body. It is from the tables of Candeze allied to the 

 European, A. procerus. 



The unique in my cabinet was collected by Mr. (jabb, in the south- 

 ern Coast Kaiige, of California. 



A. flavangularis, n. sp. — Slender, parallel, piceous shining, with distinct 

 ffiueous tinge. Head coarsely punctured, front concave and bi-impressed, an- 

 terior margin feebly reflexed. Antennae not serrate, piceous, basal joint yel- 

 low, third joint one-half longer than the second. Thorax moderately convex, 

 l)iceous black, angles yellowish testaceous, surface moderately punctured; 

 one-third longer than wide at base and- slightly narrower in front, sides very 

 feebly arcuate, slightly sinuous at middle, anterior angles slightly explanalts 

 and prominent outwardly, hind- angles obtuse not carinate slightly divergent, 

 and with a slight emargination on the outer edge. Elytra parallel at anterior 

 three fourths, moderately convex and mor6 than three times as long as wide, 

 surface with rows of rather coarse punctures replacing the stria;, interval.s 

 sparsely punctured. Body beneath brownish sparsely punctulate. Legs pale 

 testaceous. Surface above and beneath sparsely clothed with short cinereous 

 pubescence. Tarsi with second and third joints sublamellate, fourth joint 

 very small nearly hidden in the third. Length .36 inch ; 9 mm. 



Closely allied to acanthus, but differs in color and lustre and with 

 the anterior angles more prominent and the hind angles distinctly di- 

 vergent. The elytra are transversely more convex than in acanthus, 

 in which the surface is striate.
