wide at the summit, the latter feebly convex from side to side and 

 subtrenchant. Abdomen ovate, a little longer than wide. 



9 and cf. I have no specimens of these sexes of the type species, 

 nor am I able at present to obtain access to descriptions of them. 

 They do not probably differ in any great degree from their varieties.

^, 2 - 2 mm. Head and thorax ochreous brown, the thorax paler 

 than the head ; abdomen brown. Legs, antennae and mandibles pale 

 ochreous, the flagellum and middle of the femora somewhat fuscous. 

 Entirely smooth and shining. A rather narrower insect than the 

 type of the species, from which it differs chiefly by the longer meta- 

 notum, which is quite two-thirds as long as the mesonotum. The 

 dorsum of the epinotum is more convex lengthwise and the declivity 

 is less oblique. The meso-metanotal suture is, deeper. 



"$ and rf. The 9 l ias the same colour as the §; as in the type, 

 it is less shining and more punctate than the §. The cf is about 

 as large as the rj 1 of the type."

Var. BULAWAYENSIS n. V. 



This form differs from the type of the species, (with which it was 

 included by Forel, Deutsch Ent. Zeitschr. Beiheft, p. 224, 1913) in 

 the longer scapes which extend beyond the hind margin of the head 

 by one-sixth of their length. The pronotum and basal half of the 

 dorsum of the epinotum are not punctured. The metanotum and 

 epinotum are transversely rugulose and somewhat dull. Otherwise 

 like the type of the species. 



9, 4-4' 3 mm. Brown, the legs, antennae and mandibles coloured 

 as in the ^. Pubescence very fine and short, decumbent, present 

 all over. Pilosity as in the ^. Smooth and fairly shining all over, 

 at the most only microscopically punctate. Head a little wider than 

 long, the sides parallel behind the eyes, convergent anteriorly in 

 front of them, the posterior margin straight, the posterior angles 

 narrowly rounded. The scapes extend beyond the hind margin of 

 the head by one-fourth of their length. Thorax wider than the head. 

 Mesonotum fairly flat above, wider than long. Seutellum half as long 

 as the mesonotum, the posterior margin widely convex. Epinotum 

 much wider than long, the dorsum and declivity forming a single
