270 Records of the Indian Museum. [Vol. VI, 



Mr. F. W. Edwards, writing recently ' on some Ceylonese 

 Limnobiinae, puts this species in the genus Thrypticomyia, Skuse, 

 and emends the spelling of the specific name to saltens. 



cuneiformis, INIeij. Tijd. v. Ent., liv, 23 (f , pi. i, 2 (wing). 



Very closely allied, as the author says, to D. saltans, Dol., but 

 quite distinct. One $ in the Indian Museum collection is undouVjt- 

 edly this species, and is from the Dawna Hills, Lower Burma 

 (2 — 3,000 ft.), 2 — 3-iii-o8 [Annandale]. The difference in the wings 

 is sufficiently striking when the two species are placed side by side. 

 Besides being distinctly narrower in cuneiformis, the 2nd longi- 

 tudinal vein originates beyond three-quarters the length of the 

 wing, and (reckoning from the origin of the 4th longitudinal) 

 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 longitudinal 

 hindwards are much more removed to the tip of the wing than in 

 saltans. 



N.B. — It may be noted that both Doleschall and Meijere des- 

 cribe 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 tibiae. This is apparently an 

 oversight, as it is not always eas}^ to define the exact limits of each 

 tarsal joint. 



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

 in which the basal part of the wing is extremely narrowed, with- 

 out any vestige of anal angle. Personally I have my doubts of 

 the validity of Thrypticomyia on account of intermediate forms 

 {vide post.).

 5 — 6, Java. The t^^pe is in the Amsterdam Museum, from Java. 

 Specimens in the Indian Museum identified by me as this species 

 are from Kurseong, Darjiling district. 



N .B. — If Thrypticomyia be valid, this species also will fall in it.

N.B. — In addition to cuneiformis, Meijere in the same paper 

 describes the following species from Java, the types being in the 

 Amsterdam Museum : D. convergens, & 5 ; umhrata, cf 9 ; 

 punctulata, cf ; nervosa, 9 ; tenella, & 5 . The genus must 

 be extensively represented in the East, as I have in manuscript 

 the description of no less than nearly twenty additional species, all 

 from India.
