^ laticeps. 



cati, articulis subacqualibus. Men turn quadratum, latitudine fere duplo brevius, antice 

 subrotundatum. Pedes tenues, tarsi artieulo 1 ™o longiore. Approaches Boros, but the 

 antenntE are very different : the clypeus is not prolonged in front of the antennas, and 

 the lateral margin bends downwards before reaching the eyes. 



C. discicoUis. — Elongatus, piceus, punctatus, capite lateribus parallelis antice acute, 

 thorace capite plus sesquilatiore, transverso rotundato, basi angustato truncatoque ; 

 planiusculo, ad latera, et in disco leviter bi-impresso ; elytris thorace nou latioribus 

 parallelis, versus suturam indistincte striatis. Long. -62. 



29 PiuoGNATHUS. Corpus alatum elongatum. Caput ejongatum antice acutum oculis 

 parvis integerrimis, clypeo impresso, marginato labro valde transverso. Antenna; longe 

 ante oculos sitre, capite thoraceque longiores, artieulo 3 'o leviter elongate, 3 ultimis 

 subrotundatis. Mandibular apice incisa?, intus serratae. Palpi maxillares artieulo 

 ultimo leviter inflate, truncate. Mentum transversum, antice truncatum. Pedes 

 tenues, tarsi artieulo 1 ™o longiore. 



I know not what induced Mr. Randall to class this insect with the (Edemeridse, it is 

 plainly a Tenebrionite, although the position of the antennae with reference to the 

 eyes is peculiar. Only the last three joints of the antennae are meniliform. 



3° S. laticeps. — Niger, punctatus, thorace cordate, capite non latiore, obsolete car- 

 inate, elytris costis 3 vel 4 minus distinctis, antennis capite thoraceque fere longiori- 

 bus. Long. 15.
