and the epipleural strip is consequently undefined. In 

 the following new species a similar condition exists. This 

 species, according to Kuwert's definition, would belong to 

 JErioidterus, and, therefore, that genus must be abandoned. 

 Zang has already pointed out that Eriosternus of Kuwert 

 has no generic value.

E. platypleura is similar to E. p)dosus, Auriv., in size 

 and the configuration of the head, but markedly difi'ers in 

 the peculiarity already referred to in the lateral portion of 

 the elytra, in which it most nearly resembles E. planiceps, 

 Eschs, The lateral punctured area extends nearly half 

 the length of the elytra and is rather flat, the strias 

 becoming faint. The costa forming the outer edge of the 

 elytron behind is not continued forward to the shoulder, 

 so that no definite epipleura is traceable. The striee are 

 everywhere destitute of the punctures faintly traceable in 

 all the other species. The three lamellae of the antennal 

 €lub are extremely short, as in E. latericrinitus, Kuw. 

 The frontal carinse of the head at their posterior part, 

 which is marked off by distinct tubercles, are slightly 

 €urved outwards, instead of inwards as in E. pilosus, and 

 meet in a right angle. The posterior appendages of the 

 median horn are separated from it by distinct grooves and 

 form rounded bosses. The whole surface in our series of 

 specimens is less glossy than that of the other species.
