CAMEKON, FOSSORES. 231 



eitherside of tin. 1 middle, a little more than the basal half of the scutellum, post-scutellum, 

 the apical third of the Isl abdominal segment, more than the apical half of the 2nd, the 

 3rd from shortly behind the middle and about the apical third of the 4-th and 5th, the 

 apical part of the 2nd ventral and a lateral line on the apex of the 3rd, yellow; there 

 is a small black curved spot on either side of the middle of the 2nd, near the apex; 

 the black band on the 3rd has a square projection on either of the middle; the apex of 

 the 6th and the whole of the last are rufous coloured like the legs, which have the fore 

 coxio yellow in front, black behind; the 4 posterior coxae and trochanters and the base 

 of the fore femora are black; the apex of the 4 front femora narrowly and the posterior 

 broadly, yellow; the calcaria white. Head, thorax, base of abdomen and legs densely 

 covered with white pubescence. Wings hyaline, slightly infuscated at the apex, the 

 nervures rufo-testaceous; the radial cellule long, fully 3 times longer than wide, the 

 apical abscissa of radius roundly curved, longer than the apical transverse cubital 

 nervure. a 71 - 



Length 17 mm. 



Kilimaiidjaro: Kibonoto, 1000 1300 m. September. 



Mesonotum sparsely, the me tan o turn more closely and regularly punctured. Tegulae 

 yellow. In one example the scutellum is black, except for 2 curved lateral spots near 

 the middle ; this specimen has only 2 small spots on the pronotum and the black ab- 

 dominal bands are more extended. 



Dielis longinerva, sp. nov. 



Black, the sides of the clypeus - - the yellow on the sides narrower than the black 

 centre - - broadly; the black central mark broad above, becoming gradually, but not much, 

 wider towards the apex, which is rounded, and does not quite extend to the apex, basal 

 half of mandibles, a spot on the scutellums and narrow lines of equal breadth on the 

 apices of the basal 5 dorsal abdominal segments, and on the 2nd to 5th ventral, and 

 the fore tibia: 1 in front, pale yellow; the tarsi rufo-testaceous; wings hyaline, the nervures 

 pale fuscous, the radial cellule long, the apical abscissa projecting far beyond the 

 transverse cubital; it is roundly curved and is about one half longer than the basal 

 2 united, tf. 



Length nearly 7 mm. 



J/I-TM low lands. 



The hair on the head, thorax, base of abdomen and legs is white and only 

 moderately de'nse ; on the apices of the abdominal segments il is long and sparse. The 

 tiliial spines are distinct and white, as are also the calcaria. Apical half of the mandibles 

 bright ferruginous. 



A small slender species, noteworthy for the narrow apical yellow bands, of equal 

 width mi the abdominal segments, and for the black clypeal mark being much broader 

 above than with the other species. The apical abscissa of the radius, too, is longer.
