side. Wings oval, rounded at the apex, and anal angle not 

 prominent, shorter than the abdomen, surface hairy. Auxi- 

 liary vein more than one-third the length of the wing, but not 

 half its length ; no subcostal cross-vein ; first longitudinal 

 slightly arcuated, ending near the apex of the wing ; second 

 longitudinal arcuated, joniing costa just before the apex ; 

 costa prolonged beyond the tip of the second longitudinal 

 and reaching the apex ; basal portion of second longitudinal 

 about one and a half times the length of the submarginal 

 cross-vein, which is situated some distance before the apex 

 of the auxiliary vein ; petiole of the third longitudinal about 

 the same length as the anterior branch, branches divergent ; 

 apex of the second posterior cell situated before the apex of 

 the second submarginal cell ; branches of fork of fourth 

 longitudinal very divergent ; fifth longitudinal incomplete. 



This geniis differs from most of the others in the sub- 

 section in the absence of the subcostal cross-vein. It is 

 closely allied to Boletina.

Length of antennae, 0093; size of body, 0-154 x 0-016;

Antennae 2 + 14 jointed, longer than head and thorax 

 together ; joints of scapus short, nearly globular, very light 

 yellow ; first joint of flagellum light - yellow at base, but 

 upper portion and all succeeding joints dark-brown ; length 

 of joints about three times their diameter, all rather thickly 

 clotted with black hairs ; terminal joint slender but rounded. 

 Palpi very dark brown ; first joint rather slender, second 

 long and slightly swollen, third shorter and more slender, 

 fourth longest and more slender than any others. Thorax 

 bordered all round with light-yellow, central portion light- 

 brown ; one central row of short black hairs ; two lateral 

 rows, the outer one consisting of long hairs ; central row

 Scutellum light-yellow, bordered with long black hairs. Meta- 

 thorax and pleurae brown. Pedicel long and slender, support- 

 ing rather a large club, both pedicel and club being covered 

 with a short black pubescence. Abdomen light-yellow, the 

 posterior margin of each segment especially on the sides being

 Lamellae of female dark-brown, and forceps of male rather 

 large, black. Abdomen of male with broader brown borders 

 on posterior portion of abdomen than in female. Legs long 

 and slender ; coxae rather short, very light yellow ; femora 

 rather long, light-yellow, but covered with black hairs ; tibiae 

 and tarsi light-coloured, but covered with black hairs, and
