ing the hypopleura. Scutellum yellow, punctate like the thorax, with the apical half 

 black. Pleura bare, shining, with longer white hairs on the propleura, pteropleura 

 and lower portion of the sternopleura. All the bristles are black: 2 scp., 2 npL, 

 3 sa., I prsc, I mpl., i pt. ; scutellum with four bristles, the basal pair on the yellow, 

 the apical on the black part. Haltères yellow ; squamae very small, pale haired. 



Abdomen oval, as broad as the thorax, black, with the hind border of the first 

 segment ^ very narrowly and that of the second more broadly yellow ; hind border 

 of the 5th segment also narrowly yellow ; the pale pubescence on the sides of the 

 first two segments is longer ; third segment of the male with a row of black bristles 

 on the sides of the hind border ; venter yellowish , with a longitudinal median black 

 band. Male genitalia not prominent, dark yellow; the circular pregenital ventral 

 plate shining black ; ovipositor depressed, slightly longer than the fourth and fifth 

 abdominal segments taken together, shining black, the apical segment yellow. 



lyCgs brownish black, the basal half of all the femora and the first joint of all 

 the tarsi light yellow; fore coxae, and four anterior tibiae somewhat yellowish, the 

 middle tibiae in the male often wholly yellow (there are some pale hairs), those of the 

 upper side of the femora a little longer. 



Wings hyaline ; costa narrowly bordered with brown from apex of the auxiliary 

 vein to the tip of the wing, distinctly widened in the apical portion; anal cell filled 

 with brown, in the male more broadly, the brown widened at the tip; the apical 

 lower corner of the discoidal cell is somewhat filled with greyish. 



Of the described species, D. incisus of Walker seems to be not unlike this 

 species, but differs in the colouring of the legs, etc. 



This new species seems not to be rare in India ; there are in the collection four 

 males and six females from Shillong, Assam {-f5~~~H^) \ i'^om. Siliguri, N. Bengal, 

 in July (-xf-); from Kurseong, 5000 ft., E. Himalayas, ix-09 ; and from Bhowali, 

 Kumaon, 5700 ft., 15-vi-io {A. D. Imms).

A medium-sized species, very like diver sa, but at once distinguished by its 

 greater size and the four bristles on the scutellum. 



The facial band is simple. All the bristles are black. The first joint of aU the 

 tarsi is whitish. Third abdominal segment of the male ciliated. 



The caudaUts of Wiedemann belongs partly here. 



This species is known from Java. In the collection is a female from Kurseong, 

 5000 ft., B. Himalayas, g-vii-oS, (^ff-), and another from Calcutta, August, 1909. A 

 male from Java is determined by Prof. Meijere. 



1 In the numeration of the abdominal segments 1 have not followed lyoew, since the segment that 

 he numbered the first is here always considered as formed by two, the first and the second ; our third 

 segment is the second of L,oew, etc.
