of the head, face, clypeus, metapleurse, base and apex of abdomen, sides of ventral seg- 

 ments and legs white; on the rest of the body sparser and black; the mesosternum 

 laterally ends in front of the middle coxse in a stout, triangular tooth; the keel on basal 

 ventral segment is armed with a small rounded tooth near the base, nearer the apex are 

 2 larger ones united together, the first being larger than the apical, projects distinctly 

 below it and has a straight lower edge, the smaller apical tooth being rounded; base of 

 2nd ventral segment stoutly keeled in the centre to near the middle of the segment, the 

 keel ending in a stout, projecting tooth. Pygidium broadly smooth in the middle. Thorax 

 nearly 3 times longer than wide, its base above slightly rounded, the sides ending in 

 blunt tubercles; the sides beyond the basal third are roundly, but not deeply incised, the 

 incision deeper and more distinct at the base than the apex; behind the incision is a 

 distinct tooth, which becomes gradually widened from the base to the apex; at the apex 

 of the incision is a blunter, more rounded tubercle, followed by a smaller rounded one. 

 Apical slope of metanotum straight, obliquely sloped; a stout keel runs down its centre 

 to near the apex; the part on either side of this is smooth, narrow above, becoming 

 gradually widened below; looked at from above the apex is transverse, with the sides 

 rounded. $ 



Length 21 mm. 



Usambara : Mombo, June. 



Head slightly wider than the base of the thorax, longitudinally rugosely reticulated, 

 the longitudinal striae stronger and more distinct than the transverse; it is longer than 

 it is wide; the temples long, longer than the eyes; the occiput transverse. Antennal 

 tubercles smooth and shining. The mandibles end in a longish tooth, bluntly rounded 

 at the apex. Antennal scape with longish deep punctures and covered with white hair; 

 the flagellum opaque, bare, its 2nd joint as long as the following 2 united. Thorax 

 above, except at the apex, stoutly longitudinally striated-punctured; pleura? coarsely reti- 

 culated, except the base and a broad curved oblique space above, this upper part 

 extending to the apex of the metapleurte, where it is weakly, irregularly reticulated. Base 

 of abdomen broad, roundly curved inwardly, the sides projecting. Tibiee with 3 or 4 

 stout, longish black spines, their apex also having one.

Black, the thorax dark red, the pleune largely suffused with black; 2 oval spots 

 of white pubescence near the middle of the 2nd abdominal segment, and an interrupted 

 band on the 3rd. Keel on 1st ventral segment with 3 distinct teeth on the apical half; 

 the 1st tooth distinctly separated from the 2nd, which is united to the 3rd and is broader 

 and longer than the other two, which are of almost the same size and are rounded at 

 the apex; the basal half of the 2nd is bluntly keeled down the centre, the keel at the 

 apex projecting into a blunt tooth. Thorax fully 3 times longer than wide, transverse 

 at the base and apex, with the edges rounded ; the sides are slightly roundly curved in-
