NORTH OF MEXICO. ■'''-"■> 



Our species are four in number and maj be known b) the characters of the following 

 table: 



Elytra oval, not produced at api \ in i ; hairs shorter. 



1 Iair^ yellow. littoralis. 



Hairs black. 



Elytra denselj muricatelj punctured. nigropilosa. 



Elytra less densely, and simplj punctured. t enebrosa. 



Elytra elongate oval, caudate in j, ; hairs longer, yellowish ; an- 

 terior femur of ; armed. c a u <1 a t a . 



A. litto rali s, Bsch., Zool. Ail. IV. ... 13, pi. 18, fig. 6. 



This species may be known 1>\ its smaller eye and by the yellowish hairs with which 

 it is clothed. The sides of the thorax are stronglj rounded from the front to the hind 

 angles, tin' latter being mi\ obtuse. The thorax is also nearh as broad as the elytra. 

 The sculpture of the elytra consists of rather 'densely placed coarse punctures, the larger 

 id which arc arranged in indistinct striae. 



Length .26-.34 inch. 



Abundant around the Baj "!' San Francisco. 



A. nigropilosa, Lee, Arm. Lye. V. 136. 



\ prettj species, resembling, when deprived of its hair, Eleodes cordata. The sides "f 



the thorax arc very convex, but the hind angles are quite distinct, the surface being rather 

 densely and coarsely punctured. The elytra arc very broadly oval, slightly depres 

 and sculpture consists of dense inuricate punctures without any tendency to their arrange- 

 ment in stria?. The hairs which everywhere rather sparsel) clothe the body are black 

 and nearly erect. 



Length M-. is inch. 



Less abundant than the preceding, occurring in southern California, from Tejon to 

 to San 1 >iego. 



A. tenebrosa, black, less shining, ami sparsely clothed with black ereel hairs. Bead rather coarsely and 

 densel] bu( nol confluently punctured. Thorax broader than long, c >arsely and moderately densely punctured; 

 strongly rounded, slightly narrowing behind; hind angles distinct. Elytra elongate oval, regularly convex with stria 

 of targe punctures closely placed, of which the interstices arc less coarsely and irregularly punctured. Beneath black, 

 shining, coarsely bu( sparsely punctured. 



Length . 10— .46 inch. 



Easily distinguishable from the preceding species, by its more elongate form and the 

 distinct striae of punctures of the elytra. The thorax is nearlj as broad as the elytra, 

 while in the preceding species tic elytra are always more broadly oval, depressed above 

 and notably broader than the thorax.
