Âtelestus hasalis, Lee, Proceedings of the Academtj of Natural Sciences of Philadelphia, VI, 168. 

 San Diego, California ; under seaweed. The red margin of the base of the elytra extends along the side 

 almost to the middie. 



This genus, while agreeing with Atelestus in the absence of wings and the shortness of the elytra, 

 difPers essentially in the anterior tarsi of the maie, the second point of which is obliquely prolonged 

 above as far as the end of the third joint, precisely as in many species oî Anthocomus : the epistoma is 

 membranous and quite distinct, while in Atelestus it is described as indistinct. Thèse two characters 

 are sufficient to warrant the Californian species being considered as a distinct genus. 



To this genus also belong Atelestus abdominalis and collaris, Lee, loc. cit., also from the sea coast 

 of California ; in the first, the head and thorax are red; in the latter, the thorax alone.

 Congeneric with this species is Pimelia rotunda, Say, Journ. Acad. Nat. Se. Philadelphia, III, 251, a 

 much smaller and more strongly punctured species found at the eastern base of the Rocky Mountains, 

 and represents in North America Epiphysa of South Africa ; for a fuU description of this and the 

 other gênera of Tenebrionidœ hère mentioned, the student is referred to the fifth volume of the admi- 

 rable work of Lacordaire on the gênera of Coleoptera.
