80 laticeps. 



cati, articulis subaequalibus. Mentum quadratum, latitudine fere duplo brevius, antice 

 subrotundatum. Pedes tenues, tarsi articulo 1 mo longiore. Approaches Boros, but the 

 antennae are very din'erent : the clypeus is not prolonged in front of the antennae, and 

 the lateral margin bends downwards before reaching the eyes. 



C. discicollis. Elongatus, piceus, punctatus, capite lateribus parallelis antice acuto, 

 thorace capite plus sesquilatiore, transverso rotundato, L ii-;tato truncatoque ; 



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

 parallelis, versus suturam iudistincte striatis. Long. '62. 



' 9 PIUOGXATHUS. Corpus alatura elongaturn. Caput elongatum antice acutum oculis 

 parvis integerrimis, clypeo hnpresso, marginato labro valdo tvansvevso. Antennae longe 

 ante oculos sitee, capite thoraceque longiores, articulo 3 io leviter elongato, 3 ultimis 

 subrotundatis. Mandibula? apice incisce, intus serratro. Palpi maxillares articulo 

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

 tenues, tarsi articulo 1 mo longiore. 



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

 plainly a Tenebrionite, although the position of the antenna? with reference to the 

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



30 S. laticeps. Niger, punctatus, thorace cordato, capite non latiore, obsolete car- 

 inato, elytris costis 3 vel 4 minus distinctis, antennis capite thoraceque fere Icngiori- 

 bus. Long. '75.
