on the upper half of the pleuree, the lower half of the latter smooth, except for some 

 weak reticulations on the middle below; in the centre of the basal part is a long area, 

 extending from the base to the top of the apical slope, where it is obliquely narrowed; 

 the keel inside the outer edge is stouter than the others. Ventral keel short, slightly 

 dilated at the apex; it only extends to the middle of the segment, which turns from it 

 obliquely upwards. The 2nd segment is wider than long, is narrowed and depressed at 

 the apex; its back is sparsely, weakly punctured, the centre smooth; the other segments 

 are more strongly and closely punctured, especially the apical, which has a smooth line, 

 widened towards the apex, down the middle. There is a band of rufous pubescence 

 along the sides of the 2nd segment. Wings uniformly dark fuscous violaceous, the ner- 

 vures black; the basal 3 abscisses of the radius are almost equal in length, the 1st re- 

 current nervure is received near the base of the apical third of the cellule, tf. 



Length 14 mm. 



Usambara: Mombo. 



Antennal tubercles longish, rounded at the base and apex; below and between the 

 lower edge of the antennae, extending half way clown the face, is a stout, blunt keel, 

 roundly narrowed at the apex. 2nd antennal joint short, rounded; it and the 3rd are, 

 together, as long as the 4th. Temples roundly obliquely narrowed, the occiput trans- 

 verse, margined behind.

Black, the 2nd abdominal segment red all round, the entire body and legs thickly 

 covered with black hair, except on the sides and apical segment of the abdomen where 

 it is longer and white; wings uniformly dark fuscous violaceous; the nervures black; the 

 2nd abscissa of radius a little longer than the 3rd, its apex turned up straight towards 

 the costa; the 1st ventral segment with a short, bluntly rounded, distinct tooth at the 

 base. Scutellum large, conical, obliquely narrowed towards the top which is smooth and 

 shining. Metanotum with an area extending from the base to the top of the apical slope, 

 narrow, obliquely widened at the base; the sides of the metanotum are bounded by a 

 keel. (f.

Meru low lands, Ngare na nyuki, January, November. 



The 3rd antennal joint is as long as the 4th; the 2nd is very short. Head closely, 

 rugosely punctured. Base of mandibles covered with white pile; the apical tooth long, 

 gradually narrowed to a bluntly rounded point. Temples obliquely roundly narrowed, 

 the occiput transverse. Thorax distinctly wider than the head; the base rounded, the 

 apex transverse; closely rugosely punctured; there is a smooth, shining keel down the 

 middle of the mesonotum and a distinct furrow on the apical two-thirds on either side 

 of it. Scutellar depression smooth and shining. Metanotum coarsely reticulated; there 

 is a smooth space, bounded on the outerside by a curved keel, on either side of the 

 base on the oulerhalf; outside this is a straight, stout keel which extends to the top of 

 the apical slope; the latter is steep, and is more weakly and irregularly reticulated than
