plates is a distinct depression forming a sub marginal groove. TJie caudal segment 

 bears a pair of posteriorly directed spines near posterior margin dorsally and a pair of 

 median anal lobes ventrally. Head, legs, and antennae free. Antennae passing 

 behind first and second pail's of legs and over wing pads. Elytra folded ventrally 



over the posterior legs. 

 Eyes conspicuous. Pleural 

 margin of abdominal seg- 

 ments bearing mammiform 

 tubercles. Body without 

 haii-s or bristles. 



The adult 1 (fig. 26).— More 

 or less shining, elytra not 

 pubescent. Antennae with 

 the third joint scarcely as 

 long as the next two com- 

 bined, fourth joint a little 

 longer than the fifth, the 

 latter slightly longer than 

 the sixth, the latter and the 

 seventh equal. 



Pronotum usually widest 

 at the middle, frequently 

 widest just in front of the 

 middle. 



Elytra irregularly and 

 quite densely muricately 

 punctate, very minutely so 

 on the dorsum, coarser on 

 the sides and apex; from 

 each puncture arises a rather 

 short, stiff, curved, incon- 

 spicuous and semirecum- 

 bent seta. These are not 

 evident on the inflexed 

 sides. 



Otherwise as in letcheri f 

 but a little more robust.
