find no sufficient reason, at present, for treating thorn as 

 conspecific. Gravely has mentioned a specimen of intermed- 

 iate length (37 mm.), but has not stated that it is intermediate 

 also in the form of the antennal club, the puncturing of the 

 head, the median groove of the pronotum, etc.

Convex, not very elongate, the middle tibia bearing only 

 a very thin fringe of hairs above. The club of the antemia 

 consists of three moderately long jomts preceded by three very 

 short ones. The marginal processes of the head are symmetrical 

 and very short, the outer ones sharply angular but not 

 produce<l, the imier one far apart, sharp, but very short. The 

 frontal ridges, extending from the median elevation to the 

 imier marginal processes, are rather straight and enclose 

 a nearly equilateral triangle. The supraorbital ridges are 

 sharp and the parietal ridge strong. The pronotum has a few 

 scattered punctures on each side, the median groove is deep 

 and the lateral scars rather large and deep. The marginal 

 groove is a little dilated at the sides of the front margin. The 

 elytra are deeply grooved, the dorsal grooves finely but 

 distinctly, the lateral grooves fairly strongly punctured. The 

 lateral scars of the mesosternum are deep, broad, and close 

 together anteriorly. The lateral depressions of the jneta- 

 sternum are broad and densely punctured and the sides of the 

 median area irregularly rugose. 



Length, 30 to 33 mm. ; breadth, 11 to 12 mm.
