 Long., 6J 1. ; lat,, 3 1. 



Easily recognizable by the characters cited in the tabu- 

 lation. The trilobed outline of the head well denned but 

 scarcely divided, the middle lobe about three-fifths of a lateral 

 lobe in size.

 A fine large species, of a bright-reddish ferruginous colour ; 

 readily distinguishable by the characters indicated in the 

 tabulation. The trilobed outline of the head is fairly well 

 developed but not divided, the middle lobe about two-fifths 

 of a lateral lobe in size.
