wings shortly appendiculated ; the transverse median nervure is

Black, shining ; knees broadly red ; vertex and upper side of pleuraB 

 strongly punctured ; mesonotum slightly punctured, smooth, shining. 

 Parapsides dilated. Abdomen with the edges of the segments white. 

 Antennae a little shorter than the abdomen, very slightly attenuated at 

 the apex. <$ and ? . 



Length 45 lines. 



This is a larger, broader and more robust looking 

 insect than D. vestigialis. It has the puncturing on 

 the mesonotum and pleurae much less distinct, parap- 

 sides more dilated ; antennae, if anything, longer and 

 thicker at the apex ; the legs have not so much red ; 

 anterior tibiae are black, while in the other species they 

 are red ; eyes are emarginated, nor has it the white 

 marks on the second and third abdominal segments 

 observed in vestigialis.
