6. jEolopus fatus, sp. n. 



$ . Of the size of A. ihalassitms, but more robustly built.

 a little shorter than the pronotum, raodcrataly reclinate. 

 Face and cheeks smooth, very sparsely and finely punctured. 

 Frontal ridge thick, convex, feebly impressed at the ocellum, 

 sparsely punctured below the latter and densely above it ; 

 margins of the ridge very obtuse, gradually divergent from 

 the fastigium downwards, disappearing just below the 

 middle ocellum. Temporal foveoise only half as long again 

 as broad, narrowed apieally, very feebly impressed, rugu- 

 losely punctured ; their lower margin indistinct, interrupted 

 by the punctures. Fastigium of the vertex a little broader

 sulcus distinctly before its middle ; hind angle obtuse, 

 rounded, with its sides straight (not convex, as in A. thalas-

 smooth in the fore part and in the middle, and densely 

 punctured behind and on the sides ; lateral lobes not much 

 liigher than long, very feebly narrowed downwards, with the
