of four new Dipterous Insects. 61 



three shallow cavities on the interior margin of the eyes, from 

 which arise single bristles. A ntennce ^^XdiceA in front, approximat- 

 ing at the base, three-jointed, the two first joints inversely conical, 

 short, the third long, declining, ovato-conical, with a plain seta 

 arising from the base, which is rather longer than the joint. 

 Thorax broadly ovate, obtuse in front, with the scutellum consi- 

 derably produced. Abdomen subrotund, about the length of and 

 a little broader than the thorax. Legs moderate. Wings, with 

 the anal nervure very much incrassated.

Dasyneura zonata, mihi. (Plate V. fig. 3.) 



Reddish-brown. Head yellowish-brown, with the eyes darker, 

 and having four long upright bristles on the hinder margin. 

 Thorax bristly, with a spot on either side in front, two longitudi- 

 nal streaks on the upper surface, a vertical band down each side 

 just before the insertion of the wings; the scutellum, and another 

 vertical streak just below the scutellum, yellow. Abdomen with 

 the first segment margined with yellow, and the base of the se- 

 cond dark brown ; the fourth segment lighter, with a dark line 

 down the centre of the upper surface, and a dark spot on each 

 side. 



From central India. Expansion \ inch, length \ inch. 



For this insect I am again indebted to my friend J. Prinsep, 

 Esq. 



Obs. — This interesting little insect does not enter into any of 

 the present established genera of Tephritkles, as far as I am ac- 

 quainted, and I have therefore formed it into a new sub-genus 

 under the name of Dasyneura, in allusion to the thick nerve at 

 the base of the wings, a character which will at once distinguish 

 it. This thick nerve seems to be the result of the soldering to- 

 gether, as it were, of two nei'ves, which in several genera of 

 Tephritkles closely approach each other, but here they are so 

 close to each other as to form one thick broad nervure.
