tenmo are entirely rufous, I lie apical one paler than the others, which are of a darker 

 rufous colour, and are Mack above. - - Length 18 40 mm.

The amount of red on the body and legs varies; so does also the colour of the 

 wings, some examples having them lighter - - more yellowish coloured than others; but 

 on the whole, the colouration is as I have described it. It has the narrowed 2nd cubi- 

 tal cellule of pictus KOHL, but wants the yellow abdominal spots of that species; apart 

 from pictus being almost entirely black and the tibia? and tarsi testaceous, there is a 

 distinct difference in the position of the recurrent nervures; in pictus the 2nd is received 

 close to the middle, in the present species distinctly beyond the middle, close to the 

 base of the apical third. - - Numerous examples. It is probably a common species. 



Belonogaster gracilis sp. uov. 



Rufo-ferruginous, the thorax darker coloured ; the apex of the 2nd and the follow- 

 ing abdominal segments black, as is also the flagellum of the antennae; a wide trans- 

 verse yellowish spot on either side of the apex of the 2nd abdominal segment, the 

 space between them being black; legs black, the 4 anterior COXPP, trochanters and 

 femora dark rufous; wings fuscous fulvous, the costa and stigma dark ferruginous, 

 the nervures darker coloured; the 2nd abscissa of the radius about one sixth of the 

 length of the 3rd; the 2nd recurrent nervure is received shortly, but distinctly, beyond 

 the middle. Clypeus wide, distinctly longer than it is wide, sparsely punctured, the apex 

 obliquely narrowed to a point in the middle. Malar space as long as the -4th joint of 

 the antenna?. The 3rd antennal joint as long as the following 2 joints united; the 4th 

 and 5th equal in length. First abdominal segment as long as the head and thorax uni- 

 ted, the spiracles prominent; the narrowed basal part of the 3rd segment more than 

 one third of the total length. Head, thorax and apical segments of the abdomen covered 

 with a pale grey pruinose pile. $. 



The c/ 1 has the lower part of the eye incision, the face, clypeus, mandibles and a 

 narrow line on the outer orbits, the underside of the middle coxa 1 , trochanters and 

 femora are pale yellow, the rest of the anterior legs are rufo-testaceous ; the remainder 

 of the middle and the whole of the posterior are black. Apex of clypeus broadly roun- 

 ded, almost transverse. The 7th joint of the antenna? has the apical half slightly dilated, 

 the 8th distinctly, broadly, roundly dilated, the 9th is more distinctly dilated in the 

 middle, the 10th is of almost equal width, the llth is more distinctly dilated in the 

 middle than is the 9th i. c. more narrowed at the base and apex, the 12th is narrowed, 

 of equal width and almost of the same length as the lllh. Length 19 23 mm. 



Kilinuindjaro: Kibonoto, cultivated zone, 1300 1900 m. ; April and May. 



A slender species. The males have the wings clearer - - more hyaline - - than 

 they are in the females, in which they have a distinct brassy tint. The pronolum is 

 narrowly bordered with rufous.
