EBYTHBUS. 229 



regular ridges and without any distinct puncturation ; tne surface 

 dull. Elytra with the lateral ernargination near the base not 

 deep ; the surface dull all over, closely and not very strongly 

 punctured, the punctures somewhat evenly distributed, not much 

 larger near the base than they are near the apex ; apices rounded, 

 briefly mucronate at the suture. 



$ . Antennae much shorter than the body ; prothorax less 

 abruptly constricted at the apex, closely, sub-rugosely punctured 

 above ; abdomen entirely of a dull reddish tint. 



Length 13| ; breadth 3 mm.

Pronotum, except at the front margin, and elytra red ; head, 

 body beneath, legs, scutellurn and antennae black. Head finely 

 and densely rugulose-punctate. Antennae of c? slightly longer 

 than the body ; third joint slightly longer than the first and dis- 

 tinctly longer than the fourth ; fifth subequal in length to the 

 third, widened and strongly angulate at the apex in front ; sixth 

 to tenth also dilated and strongly angulated at the apex ; eleventh 

 a little longer than the tenth. Prothorax subnitid, subcylindrical, 

 narrowed very slightly in front ; transversely striated and rather 

 sparsely punctured above and on the sides ; very densely punctured 

 below and around the outer borders of the acetabula. Elytra 

 strongly and very closely punctured, especially near the base, 

 where also they are slightly nitid ; rounded and unarmed at the 

 apex. Thorax densely and rather strongly punctured, the abdomen 

 finely and less closely punctate. Legs subnitid, feebly and sparsely 

 punctulate, and, like the underside of the body, very scantily fur- 

 nished with short greyish pubescence. Femora not carinate, and 

 not strongly thickened. First segment of abdomen as long as the 

 second and third united, the last segment sinuate at the apex.
