c? ? . A near relation of D. longifrons, from which it differs chiefl)' in the 

 (^-genitalia. The npper and lower autepygidial bristles are of practically even 

 length in the c? as well as the ? . The last but one geual spine is broader than 

 in 1>. longifrons. Both sexes have three rows of bristles on the pronotnm, and a 

 pronotal comb of thirty or thirty-one spines. The mesopleura bear 38 (37) 

 bristles and the metepimeram 32 (33) in both sexes, the basal abdominal sternite 

 having 15 (17) in the (?, and 23(23) in the ?. The eighth sternite has on each 

 side 56 (61) in the c?, and the eighth tergite below the stigma 39 (41) in the ?, 

 while the seventh tergite bears on both sides together a row of twenty-three long 

 bristles, and fort3--eight additional bristles in the S, and sixteen and thirty-six

respectively in the ?, the numbers of bristles on the seventh sternite being in the 

 tj 11 + 41, and in the ? 20 -|- 63. The species has a comb on the first abdominal 

 tergite in both sexes, the spines in the other abdominal combs being in the S 

 2, 7, 8, 9, 3 (1, 8, 8, 9, 3) and in the ? 2, 8, 9, 8, (2, 7, 8, 8, 0). 



The ninth tergite (text-fig. 41) of the 3 bas six or seven long bristles at the 

 oblique distal margin. The long process of the clasper is less widened in the 

 middle than in D. longifrons, and its ni)per distal angle a little less prominent. 

 The ninth sternite (IX. st.) is much slenderer distally than in any of the other 

 species, and bears a dense comb of bristles from the apex to the centre, the series 

 being interrnpted twice (text-fig. 41). 



Length (mounted specimens) : i 3-5 mm., ? 4-3 mm.
