A REVISION OF THE GENUS LEPTOCONOPS, SKUSE. 



19 



Of the species of Leptoconops occurring in the Mediterranean Httoral L. flaviventris 

 apparently most closely resembles L. irritans in general facies. In both species the 

 abdomen is normally pale in colour — whitish or yellowish — but they should be easily 

 separated by the structure of the claws.

Leptoconops indicus, Kieff. 



Schizoconops indicus, Kieff., Ann. Mus. Nat. Hung, xvi, p. 135 (1918). 



This species was made the type of the genus Schizoconops by Kieffer on account of 

 its toothed or bifid ungues. This character alone, however, cannot be considered of 

 sufficient importance to warrant the creation of a new genus ; and even were it of 

 subgeneric value the name Schizoconops would sink under Mycterotypns (see p. 3). 



The chief characters, taken from Kieffer's description, are as follows : — - 

 $. — Shining black. Antennae brown, the fourth to the thirteenth segments 

 transverse, at least twice as broad as long ; fourteenth segment conical, equal in 

 length to the four preceding segments together. Wings white, with pale veins ; 

 first and third veins not reaching the middle of the anterior border, fifth vein 

 bifurcating much beyond the extremit}^ of the third vein. Halteres white. Legs pale
