TENEBRIONIPAE. 215 



Tribe IV.-EPITRAGI1VI. 



Body oval, winged ; epistoma trilobed (in our species) ; labrum 

 prominent ; mentum very large, entirely filling the gular cavity ; 

 ligula and maxillae concealed ; elytra with narrow epipleurae ; 

 prosternunr (in our .species) prolonged and pointed, fitting into 

 the deeply emarginate mesosternum ; metasternum long, with 

 narrow side pieces ; middle coxse without trochantin, inclosed 

 by the sterna ; hind coxa? approximate, intercoxal process of the 

 abdomen acute ; tarsi pubescent beneath. 



Our species are few in number, and belong to Epitragus ; they 

 are found on tall grass, in moist places. None have yet occurred 

 in the Pacific district. E. canaliculatus Say, is remarkable for 

 the thorax of the male having a broad, dorsal groove, limited by 

 elevated ridges. 



The characters here given do not apply to the tribe as received 

 by Lacordaire, which might probably with advantage be divided. 



Tribe V.— ANEPSHNI. 



Body elongate oval, apterous, sparsely hairy ; head received in 

 the thorax as far as the eyes, which are almost divided, small and 

 coarsely granulated ; front dilated at the sides over the base of 

 the mandibles, submarginate anteriorly, partly covering the la- 

 brum ; mentum large, flat ; maxillae exposed, ligula concealed ; 

 gular peduncle broad, distinct ; palpi not dilated; antenna? 11- 

 joiuted, very slightly thickened externally ; thorax not applied 

 closely to the trunk ; metasternum with narrow episterna ; middle 

 coxae surrounded by the sterna, without trochantin ; hind coxae 

 not widely separated, intercoxal process of abdomen triangular ; 

 legs short, tibial spurs distinct, especially the anterior ones, ante- 

 rior tibiae strongly dilated and compressed ; tarsi short, with 

 small spines beneath. 



Three small species, from the Colorado Desert, constitute this 

 tribe. Anepsius was placed by Lacordaire with the Ulomini, 

 from which it differs not only by the larger mentum and concealed 

 ligula, but by the absence of any coriaceous margin on the third 

 and fourth ventral segments. 



The two genera are distinguished as follows : — 



Antennae slender, gradually thickened externally. Anepsius. 



Antennae short, four last joints slightly but suddenly larger. Batulius.
