abdomen white, on the rest of (ho back black; apical segment punctured, narrowly smooth 

 in the centre. The hair on the legs white; it is thicker on the tibia? than on the femora, 

 and denser on the tarsi than on the tibia?; the latter have 2 or 3 black spines and 

 white spurs. 



Mn! ilia (Dolichomutilla) apicircticnlata, sp. nov. 



Black, the thorax red, entirely closely reticulated-punctured above; the propleime 

 similarly punctured, the mesopleura? smooth, except for a triangular, reticulated space in 

 the centre below, the metapleuro? smooth; base and apex of thorax bluntly rounded 

 above; central part of ventral basal keel with 2 distinct teeth of almost equal size; the 

 keel on basal half of 2nd segment distinct, not projecting much at the apex, but with 

 the .tooth distinct enough. $. 



Length 12 mm. 



Usamlara: Mombo, June. 



The hair on thorax and top of abdomen is black; on the sides and ventral surface 

 of abdomen while, as it is also on the legs; calcaria white. The 2nd joint of the an- 

 tennal flagellum slightly longer than the following 2 united. 



Mut ilia (Dolichomutilla) heterodonta, sp. nov. 



Black, the head and thorax lighter in tint than the abdomen which is of a deeper 

 black colour; the 3rd abdominal segment with 2 oval spots of white pubescence shortly 

 behind the middle; the 3rd with a wide interrupted band of similar pubescence; thorax 

 about 4 times longer than wide; the base transverse, the apex rounded; at the apex of 

 the basal third of the thorax, on the sides above, is a longish tooth, with the apical 

 (and smaller) part narrowed ; shortly beyond the middle are 2. blunt teeth, of which the 

 basal is the larger and rounder; the apex of the thorax has a gradually rounded slope 

 and is gradually and slightly narrowed. Ventral keel with 3 teeth on apical half; the 

 1st roundly curved at the base, the bottom bluntly rounded; the 2nd is larger, trans- 

 verse below r ; the 3rd is the smaller and becomes gradually narrowed to a blunt point; 

 Ihe basal half of the 2nd ventral segment bluntly keeled, the keel ending in a somewhat 

 sharp tooth. $. 



Length 13 mm. 



Meru low lands, November. 



Head as wide as the base of the thorax; the temples clearly longer than the eyes, 

 hardly narrowed towards the back; occiput transverse; the front and vertex widely, deeply 

 reticulated,; covered, not very thickly, with silvery pubescence, and, more sparsely, with 

 long black hairs; both kinds being denser on the malar space and face than elsewhere. 

 Upper part of thorax coarsely longitudinally reticulated, this being also the case with 

 the propleura?; the mesopleurae smoolh, weakly reticulated at the base; the lower apical 

 part thickly covered with depressed white pubescence; the metapleuree smooth at the 

 base above, the rest reticulated like the metanotum. The mesosternum, in front of the 

 middle coxa?, projects into a large looth, of which the basal end is the larger. Upper
