DICKANOMYIA. 373 



the basal part extremely contracted, without vestige of alula or 

 anal angle, increasing gradually in width to the widest point, this 

 being beyond the middle of the wing. Stigma brownish, distinct 

 but ill-defined. The 2nd longitudinal vein begins at fully four- 

 fifths the length of the wing, the adjacent veins below it being 

 more crowded distally than even in I), kobusi. Discal cell present, 

 oblong, inner side nearly in a line with the cross-veins, the cell 

 about as long as the 2nd and 3rd posterior cells. Halteres very 

 long and slender, pale, clubs black.

In the above description the characters of the male are adapted 

 from Meijere, the female (previously unknown) being described 

 from a single example of this sex in the Indian Museum from the 

 Dawna Hills, 2000-3000 ft., 2-3.iii.08 (Annandale). 



Type c? in the Amsterdam Museum. 



Meijere only described the male from a single specimen from 

 Java, but from the peculiar shape of the wing and the character- 

 istic venation there can be no possible doubt as to the identity of 

 the species. The difference in the wings of D. saltans and cunei- 

 formis is sufficiently striking when the two species are placed side 

 by side. Besides being distinctly narrower in cuneiformis, the 

 2nd longitudinal vein originates beyond three-quarters the length 

 of the wing, and (reckoning from the origin of the 4th longi- 

 tudinal) the inner end of the discal cell is placed at four-fifths of 

 the wing's length, whilst in saltans it occurs very distinctly before 

 that distance. In Meijere's species the veins from the 2nd longi- 

 tudinal hindwards are much more removed to the tip of the wing 

 than in saltans. 



It may be noted that both Doleschall and Meijere describe the 

 tarsi of their respective species as snow-white. This is indeed so, 

 but the basal part of the metatarsus (varying from a third to a 

 half) is dark, like the tibia. This is apparently an oversight, as 

 it is not always easy to define the exact limits of each tarsal 

 joint. 



Mr. Edwards refers this species also to Fhrypticomyia, a genus 

 in which the basal part of the wing is extremely narrowed, without 

 any vestige of an anal angle. Personally I have my doubts of the 

 validity of Thrypticomyia on account of intermediate forms.

3 $ . Head obscure brownish yellow ; proboscis and antenna 

 a little clearer ; palpi dark. Thorax brownish yellow, the posterior 

 half distinctly lighter, including scutellum and metanotum. Abdo- 

 men brownish yellow, brown or blackish ; genitalia normal. Legs 

 brown, a little yellowish on coxae and base of femora, the tips of 

 the femora very slightly thickened ; basal half of metatarsi black, 

 the remainder of the tarsi snow-white. Wings clear pale yellow,
