The absence of fascicles, and the insertion of scape are very 

 distinctive of this species. The rostrum is longer, and more 

 highly polished in 9 than in $. On one specimen there is a 

 feeble transverse elytral fascia of dark scales at about one-tliird 

 from the base, and several spots near the apex. 



Sympiezoscelus, Mitrastethus, and Bepharus. 



These three genera possess many, and some unusual features 

 in common; indeed, it is questionable whether the three names 

 should be retained; however, as the tibise of St/mpiezoscelus are 

 very different from those of Mitrastethus and Bepharus, and the 

 insertion and length of the scape, and the shape of the elytra in 

 Bepharus are different from those of the others, it is perhaps 

 advisable to retain all three. To avoid repetition, the features 

 they possess in common are here given. 



Head convex, not concealed by prothorax; ocular fovea small 

 and deep. Eyes small, coarsely faceted, distant. Two basal 

 joints oi funicle elongate, the others transverse. Prothorax flat 

 or very feebly convex, subconical, sides rounded from near apex, 

 apex produced, not half the width of base, base bisinuate, con- 

 striction rather feeble, ocular lobes obtuse. Scutellum small, 

 rounded, distinct. Elytra closely applied to and on a level with 

 prothorax, base trisinuate, shoulders slightly produced. Pectoral 

 canal moderately wide and not deep^ terminated slightly nearer 

 anterior than intermediate coxte. Mesosternal receptacle flat, 

 base truncate, side somewhat emarginate and then oblique to 

 apex, emargination semicircular; cavernous. Metasternum large, 

 distinctly longer than basal segment of abdomen; episterna large. 

 Abdomen large, sutures distinct; 1st segment about once and one- 

 third the length of 2nd, intercoxal process rounded; 3rd and 4th 

 large and flat, their combined length more than that of 2nd or 

 apical, with very deep sutures, Legs moderately long; femora 

 stout, edentate, not grooved except near apex; tarsi slightly
