ters and the greater part of the femora black ; wings liyaline, 

 the middle clouded with fascoiis, the nervures and stigma 

 fuscous, the latter white at the base. 5. 



Length 10 mm. ; terebra 8 mm. 



Ceylon (Nietuer). 



Pubescence long, sparse, erect, white. Front and vertex 

 closely, distinctly but not very strongly transversely striated ; 

 the temples longitudinally striated ; the malar space smooth. 

 Face rugosely transversely striated ; the striœ stronger and 

 more distinctly separated on the sides below. Antennae almost 

 bare. Temples broadly rounded, longer than the eyes ; the 

 occiput broadly roundly incised. Pronotum transversely, the 

 pleurae longitudinally striated, the striae on the former rounded. 

 Mesonotum trilobate, the base of the middle lobe finely, the 

 lateral lobes more strongly rugosely punctured ; the depres- 

 sion between the lateral lobes stoutly transversely striated, 

 the striated part bordered near the outer edge by a longitu- 

 dinal keel. Scutellum very finely closely transversely striated.
