Description, — Body oval ; pale brown, approaching to 

 flesh-red, and, when alive, tinged with purple ; dotted all over 

 with numerous punctures. Antennae, white, setaceous: the 

 superior very short, with the two basilar joints much dilated, 

 and forming a broad, movable, coloured plate before the eyes ; 

 the third joint small and cylindrical ; the ultimate one, multi-

 superior, the three basilar joints short, unequal ; the fourth, 

 longer and cylindrical ; the ultimate longer than the whole, 

 and multiarticulate : the bases of the antennae approximate,

 brown, anterior and marginal, extending obliquely backwards, 

 occupying all the cranial segment except a small point pro-
