30 [February, 



Locality. Middle States, Southern States, Nebraska and Upper Mississippi . 



There is considerable variation in the marking ; one specimen from the 

 Southern States was observed having the disc of the elytra irregularl_y ferruginous 

 with a broad yellow margin. Another speqimen from the South has the elytra 

 ferruginous and the spaces between the suture and 1st, 2 to 3, 5 to 6 and 8 to 9th 

 strijB yellow. 



These differences are sufficient to account for the supposed species above 

 quoted.

 penultimate joint conical, last joint cylindrical, truncate shorter than the preced-

 joint small. Coxa; widely separated. 



The genus may be divided into three divisions : 



1. Tropical species, in which the mesosternum is produced into a horn. 



2. Those in which the mesosternum is slightly excavated, and the feet without 

 spines. Sp. 1 4. 



3. Those in which the mesosternum is slightly protuberant, and the anterior 

 femora are armed with spines, at least in the male. Sp. 5.
