TENEBRIONIDAE. 223 



front and rounded on the sides, coarsely punctured, with a faint 

 smooth dorsal line, and the elytra with faint costae between the 

 rows of irregular fovese, may be called Branchus Jioridanus. 



Tribe IV.— CONIONTINI. 



Body oval or globose, apterous ; epistoina covering the base 

 of the mandibles; labrum prominent; mentum moderate, emar- 

 ginate ; gular peduncle short or almost obsolete ; ligula promi- 

 nent, emarginate ; maxilla? exposed ; eyes transverse, small, mode- 

 rately coarsely granulated ; elytra usually with narrow epipleurse ; 

 anterior coxas subtransverse ; middle coxa? with distinct trochantin, 

 side pieces of mesothorax attaining the coxal cavities ; meta- 

 sternum very short, episterna wide, epimera visible ; hind coxa? 

 approximate ; irrtercoxal process of abdomen acute ; tibial spurs 

 long, tarsi spinous beneath ; the first joint of hind tarsi very 

 long. 



Antennae very short; 1st joint of anterior tarsi prolonged into a large spine. 



Coelds. 

 Antennae long ; tarsi simple ; 



Anterior tibiae with the outer angle much prolonged ; 



Inflexed portion of elytra wide ; 



Epipleuras suddenly dilated at the base, Discodemus. 



Epipleurae gradually wider in front. Eusattus. 



Inflexed portion of elytra narrow, limited by epipleural margin. 



Conipinus. 



Anterior tibia truncate at hip ; inflexed portion of elytra narrow. 



Coniontis. 



Ccelus contains two species found on the California seashore. 

 Discodemus is founded upon Zojihosis reticulata Say., from Kansas 

 and Arizona, and Conipinus upon Eusattus dubius and ]jroductus 

 Lee, from Arizona; Eusattus is distributed from Kansas to 

 Texas, California, and Oregon. Coniontis contains several Cali- 

 fornian species, one from Oregon and one from Kansas. These 

 insects are all found under stones, &c. on the ground. 



Sub-Family III.— TENEBRIONIDAE (genuini). 



In this sub-family the posterior margin of the third and fourth 

 ventral segments is coriaceous ; the middle coxa: are usually pro- 

 vided with a distinct trochantin, and their cavities extend out- 

 wards to reach the epimera ; sometimes (Ulomini) the. trochantin 

 is absent, but in these cases it appears to me rather to be united
