ORPHNUS THORACICUS, new species. 



Oval, convex, rufo-castaneous, polished. Head very short, sparsely 

 liunctulate; clypeal margin reflexed, serrate; front with a strong, sub- 

 erect, conical horn at middle and a short carina at inner margin of the 

 eye. Thorax strongly transverse, continuously margined; anterior 

 angles acute, posterior obtuse, nearly rounded; base truncate; disk 

 deeply and broadly excavate from the anterior margin three-fourths of 

 the length toward base; excavation bilobed behind; the sides in front 

 strongly couically elevated; a few coarse punctures on the sides of the 

 disk, Scutellum semioval, smooth. Elytra twice as long as thorax, 

 broadlj' conjointly rounded at apex; humeri prominent; disk with short 

 irregular strite of coarse i)unctures near the scutellum and around the 

 humeral umbones^; sutural stria obsolete. Ventral surface sparsely 

 hirsute. Anterior tibia^ strongly tridentate; spurs of posterior tibia* 

 long, reaching the apex of second tarsal Joint.

SERICA CONSIMILIS, new species. 



Broadly oval, dark ferruginous, sericeous, somewhat shining, rather 

 densely punctate, rufo-ciliate at sides. Anteuuie ten-johited, light fer- 

 ruginous; club three-jointed, somewhat longer than the stem. Clypeus 

 separated from the front by an obtusely elevated, strongly arcuate line, 

 densely punctate, with apical margin truncate, obsoletelj' tridentate. 

 Thorax evenly convex, twice broader than long, widest at base, slightly 

 narrowed to middle, strongly obliquely convergent in front: anterior 

 angles produced, posterior angles obt use. Scutellum triangular, smooth 

 at apex. Elytra at base broader than thorax, somewhat wider at mid- 

 dle, broadly rounded at apex, rather strongly punctatostriate; sutural 

 stria more deeply impressed posteriorly^; intervals irregularly punctate, 

 slightly convex. Pygidium convex, punctate. Ventral surface and 

 legs ferruginous, tarsi darker. Anterior tibia* strongly bideutate. 

 Claws all equally cleft.

SERICA NITIDIROSTRIS, new species. 



Broadly oval, convex, light ferruginous, sericeo-opaque, vaguely 

 rugosopunctate. Antenna* testaceous, tenjoiuted; club four jointed, 

 somewhat longer than the stem, the first lamella only one-fifth as long-
