a kind of support to it. The scutellum is obsolete. The 

 elytra are shorter than the abdomen, slightly margined, 

 at the end rather widest, truncate and subemarginate, 

 taken together of an oblong-oval shape. Their surface 

 is distinguished by nine lines of deeply impressed points; 

 the line nearest the suture towards the base diverges a little, 

 so as to give room for another very short line of points, 

 running from the base a little way down the suture : in the 

 space between this and the diverging line two impressed 

 points are observable. The interstices between the lines are 

 rather convex, and very minutely punctulate. The abdomen 

 consists of five segments with a very obtuse anus. 



Fabricius describes the tarsi of this insect as consisting 

 only of four joints, with the last bilobed; from which it is 

 plain he did not take into the account the terminal or un- 

 guicular joint. Without this, however, no insect has five 

 joints in its tarsi. In Panzer's figure, which, although 

 too blue, is certainly intended for our insect, the tarsi have 

 only four joints with the last but one bilobed. This is 

 clearly a mistake. M. Latreille corrects this error, by 

 placing it in a section in which the species have all the tarsia 

 of five joints.
