TWO NEW SPECIES OF CEBRIO (COL.). 



By Charles Schaeffer, Brooklyn, N. Y. 



Cebrio antennatus new species. — Castaneous, head black or piceous, an- 

 tennae, legs and underside paler. Head moderately densely punctate; 

 labrum emarginate; mandibles as in hicolor; last two joints of maxillary 

 palpi nearly equal in length ; antennae rather strongly serrate, reaching 

 to about basal fourth of elytra, third joint about half as long as fourth, 

 last joint elongate and feebly constricted. Prothorax transverse, sides 

 almost straight, rather feebly converging towards apex, hind angles feebly 

 divergent, surface moderately coarsely, not densely punctate. Elytra! 

 striae rather feebly impressed; intervals nearly flat and moderately densely 

 punctate. Prosternal process hearly as wide between the coxas as in 

 bicolor. Abdomen finely, not closely punctate; last ventral more densely 

 punctate than the other segments, apex entire and broadly rounded. 

 Length 17 mm. 



Arkansas (coll. Dietz).

 in having longer antennae, entire last ventral segment, which is
