TENEBRIONIPAE. 371 



eniargiiiate ligula; the ('i)i[)l(!iirif are suddenly dilated at the base 

 in all three. 



The species of Brauehus somewhat resemble in form Opatrum, 

 and are opaque, coarsely punctured, and slightly pubescent; on 

 the elytra are rows of vague fovete as in Euaattus reliculatus, but 

 more strongly marked. They are known to us from Nicaragua, 

 Island of New Providence (Bahama), and Florida. A species 

 from Honduras differs from the others by its anterior tihiaj being 

 truncate, and constitutes the genus Anectus Horn; in form it 

 resembles a broad Asida rather than Opatrum; the tibia? of the 

 other species are prolonged at the outer angle, though less so 

 than in Eusattus and allied genera of Couiontiai.

Ccelus contains two species found on the California seashore. 

 Eusattus (including Discodemns and Covipinui^) is distributed 

 from Kansas and Texas westward to Oregon, through both Cali- 

 fornia and Arizona Coclotaxis occurs in the (xuadnhipe Island, 

 west of the peninsula of California, and is included in the present
