404 AXTHEIBIDJE. 



[LeConte. 



not extend beyond tlie prolonged angles of the second joint. The beak is flat 

 and parallel on the sides ; the antennal cavities extend to the eyes, which are 

 oval and coarsely granulated, somewhat truncate in front. The side mar- 

 gin of the prothorax extends to about the middle ; the base is slightly bisin- 

 uate, and the lower basal margin is very well defined, so that when the 

 prothorax is deflexed, it might be supposed that the transverse ridge was 

 not absolutely basal. The same is the case, though to a less extent, in the 

 genera of the preceding group. The front coxae are contiguous, and the 

 mentum is but feebly emarginate in our species ; the buccal fissures are 

 rather wide. 



CBATOPABIS Sch. 



Our two species differ by the color of the pubescence : 

 Brown, with the sides of the prothorax, and large elytral 

 spot concave backwards, yellowish-gray, rest of the sur- 

 face mottled 1 . lunatus. 



Black, varied with white ; elytral spot irregular, extend- 

 ing to the base, enclosing a quadrate black scutellar 

 space, apex of elytra white \ 2. lugubris.

Atlantic States, abundant southwardly. 



Group III. Bracby tarsi. 



In this group the beak is gradually narrowed from the eyes forwards, so 

 as to become trapezoidal in form ; the antennal cavities extend to the eyes, 

 which are coarsely granulated and emarginate in front. The first and 

 second joints of the antennae are stout, the second a little longer, 3-8 

 shorter, gradually a little wider ; 9-11 much wider, forming an oval com- 

 pressed sensitive club. Prothorax rounded in front, overhanging the head, 

 basal ridges flexed rectangularly at the angles, but extending only a very 

 short distance along the sides; inferior basal margin acute. Elytra with even 

 and equal interspaces. Tarsi with the first joint scarcely longer than the 

 second, which is triangular and emarginate ; third deeply bilobed, not nar- 

 rower than the second, claws toothed near the tip, so as to appear cleft. 

 Mentum deeply emarginate with lobes, rounded at tip ; gula transversely 

 impressed. 



Our species represent two genera, one of which has not been previously 

 recognized.
