2 nd less strongly nodose. The eyes at the antennae are separated by 

 alraost the saine distance as they are at the vertex. The l st abdominal 

 segment is clearly longer than the 2 nd and 3 nl united. 



Characteristic of this species is the transverse trilobate keel over 

 the antennœ. 



Stiziis pulchritinctus sp. n. — Black, shilling, the abdomen 

 tincted with metallic violaceous and bine; the antennal scape, 

 except above, face, a Une on the inner orbits from the face to slightly 

 above the antennal scape when pressted against the front, face, 

 clypeus, labrum, base of mandibles, a line on the apex of the 

 pronotum reaching to the tubercles, the tubercles, a minute spot 

 on sides of mesonotum, teguhe, scntellar keels, a triangular spot 

 on the sides of scutellnm, longer than it is wide at the apex, the 

 narrowed end at the base, the greater part of the post-scutel- 

 lnm, the sides of the apical slope of the metanotum, including 

 the teeth, a line on the apices of the basai 5 abdominal segments, 

 that on the l st , much wider than the others and bilobate, the 2 nd 

 line trilobate, a line on the apex of the 2 nd ventral and narrower 

 Unes, interrupted in the middle, on the following 3, pale lemon- 

 yellow, as are also the greater part of the fore femora, the tibise, 

 except for a longish line on the inner side, that on the hinder ail 

 round the apex and the greater partof the hind tarsi, black. Wings 

 hyaline, the stigma and nervures black, the 2 nd cubital cellule 

 almost appendiculated, the l st transverse cubital nervure in front 

 straight, oblique from shortly below the middle, the 2'"' broadly

Lukombe, 7 th October (A. Koller). 



The incision on the sides of metanotum large, almost semicircular, 

 placed on the top half, the teeth large, bluntly triangular. Body 

 covered, but notdensely^ with a grey pile, smooth, the base of the 

 mesonotum from near to the middle, closely, irregularly longitu- 

 dinally striated. The antennœ are almost double the distance from 

 each other as they are from the eyes. Clypeus above bounded by a 

 narrow curved furrow; as long as it is wide below, Eyes strongly 

 converging below. 



This species has the for m and size of S. Braunsii Kohl and has 

 the incision on the sides of the metanotum pretty much as in 

 S. tridens, being wide and rounded. It is more slenderly built than • 

 a Cape tf of what I make out to be S. Braimsii, that has the body 

 and legs much more densely haired and with the pile longer; it 

 has also the yellow markings more extended and wider ail over,
