Of the two species here described, the first shows more resemblance to the genus 

 Ensina, in which it and the aUied species are often placed. But at present I prefer to 

 leave it in Oxyna, the genus Ensina being restricted to the single species sonchi, which 

 is distinguished by the very depressed head, hyaline wings with the first vein reaching 

 the small cross- vein and the body partly yellow. 



The two species are very easy to distinguish : — 



1 (2j. Proboscis very long and slender, the terminal portion being as 



long as the basal ; abdomen grey with black spots ; wings 



with less marked pattern and rather diffuse reticulation. . . sororcula, Wied. 



2 (i). Proboscis shorter and thicker, the terminal portion shorter than 



the basal ; abdomen shining black ; wings with intensive 



pattern . . . . . . . . . . parca , n. sp.

This species is very like the European elongaiula, but is distinguished by the un- 

 spotted stigma and the more diffuse reticulation of the wings. Thorax, scutellum and 

 abdomen entirely grey, the abdominal black spots more or less distinct. Bristles black ; 

 ovipositor shining black. The wing-pattern more or less dark, often very light. 



This species seems to have a wide distribution in warm countries ; Wiedemann 

 described it originally from Teneriffe, where Becker found it very common ; Wollas- 

 ton records the species from Madeira and I have seen numerous specimens from 

 Krythraea, East Africa ; the species is also found in Egypt. Van der Wulp describes 

 his variipennis from Ceylon, and I think that the synonymy is right, because Czerny 

 compares the species with elongatula. The Central American species picciola, Bigot 

 ( = aurifera ,T\iovcis. and Äwmz7/s,Loew), which is placed in Ensina by American writers, 

 is an allied form ; but it seems to be distinct in having always a pair of very small 

 but distinct apical bristles on the scutellum, which in the present species are only 

 found exceptionally.
