Atelestus basalis, Lee., Proceedings of the Academy 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 middle. 
This genus, while agreeing with Atelestus in the absence of wings and the shortness of the elytra, 
differs essentially in the anterior tarsi of the male, the second point of which is obliquely prolonged 
above as far as the end of the third joint, precisely as in many species of Anthocomus : the epistoma is 
membranous and quite distinct, while in Atelestus it is described as indistinct. These 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.

4. E. YKNTiiicosus, niger nitidus, pilis longissimis albidis versus latera lanuginosus, capite tlioraceque 
impunctatis, hoc versus latera rugis paucis elevatis notato; elytris parce subtiliter punctatis, punctis 
versus marginem muricatis; pedibus longe pilosis. — Long. 13 1/2 mill. — Tab. XII, fig. 8.

Congeneric with this species is Pimelia rotunda, Say, Journ. Acad. Nat. Sc. 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 full description of this and the 
other généra of Tenebrionidæ here mentioned, the student is referred to the fifth volume of the admi- 
rable work of Lacordaire on the généra of Coleoptera.

tundato, angulis anticis porrectis ; elytris ventricosis rotundatis, thorace plus duplo latioribus, 9 -seriatim
