EUPTERYX ABROTANI. 121 



rounded at the apex, with famt buff neuration. The 

 abdommal apex is furnished with fine hairs. The 

 black ovipositorial saw of the female is often freely 

 exserted. The under side is all yellowish white. 



Mr. Edwards says, " Exceedingly like a pale whitish 

 variety of E. pulchella." Individuals show faint dun- 

 coloured marks on the pronotum. The examples 

 which have come under my notice do not approach 

 the marked colouring of that species. The male geni- 

 talia will be found to differ considerably in structure 

 from E. pulchella. 



Taken on oaks at Weycombe, Haslemere ; also at 

 Tyntesfield, Somersetshire ; and Felthorpe, Norfolk.

 its specific name.
