strongly and regularly widened downwards, \^ ilhout 

 any trace of constriction at tlie ocellum, obliterate 

 near the clypeus. Foveolae oi' vertex very short, sub- 

 quadrate with the upper anterior angle rounded, an- 

 teriorly separated from each other by only a very 

 narrow ridge. Fastigi uni of vertex strongly sloping 

 forwards, longer than it is broad, pentagonal but 

 with the side angles rounded; the apical angle about 

 90°; surface distinctly impressed. Occiput strongly 

 convex, with a very distinct median carina through- 

 out, and with two somewhat irregular submedian 

 carinae forming prolongation of the lateral carinae of 

 fastigium, but more approximated to each other than 

 those; surface between the carinae with regular trans- 

 verse rug'Osities. Eyes strongly oblique, large; sub- 

 ocular distance equal to the horizontal diameter of an 

 eye. 



Pronotum strongly laterally compressed, distinct- 

 ly narrower than the head, somewhat constricted in 

 the middle. Anterior margin rounded, posterior one 

 obtusely angulated, with the sides of the angle dist- 

 inctly concave. The typical sulcus well marked, 

 placed behind the middle; the first and the second 

 sulcus feeble. Median carina well developed, but 

 raised less strongly than in D. anntolicus. Lateral 

 carinae before the first sulcus well developed, callous, 

 distinctly bowed outwards^ between the sulci almost 

 obsolete, in metazona developed, callous, straight. 

 Lateral lobes rugulose, narrowed downwards; ante- 

 rior margin oblique; lower margin rotundato-promi- 

 nent in the middle; anterior and posterior angle ob- 

 tuse, rounded.
