pilosity ; pubescence wanting except on the flagellum and tarsi. 

 Mandibles nearly smooth, with here and there some indistinct longi- 

 tudinal striae and pilose punctures, moderately long, narrow, with a 

 distinct and very oblique masticatory margin at the apex, which ends 

 in a curved pointed tooth. When the mandibles are closed there is 

 a large space between them and the clypeus. The head is smooth, 

 with sparse and shallow pilose punctures, somewhat stronger on 

 the sides of the head ; the latter is of a reversed trapeze shape, being 

 much wider in front than behind, and also wider there than across 

 the eyes. Clypeus short, sharply carinate, with striae on each side 

 of the carina which extend back a short distance between the 

 antennal sockets and the base of the mandibles; the carina is 

 produced in front to form a short and rather indistinct projection 

 or snout, which is almost wider than long. On each side of the 

 projection the anterior margin of the clypeus is curved slightly 

 S-shaped. The eyes are nearer the base of the mandibles than the 

 posterior angles of the head. The lower margin of the mouth is 

 without a small tooth. All the joints of the flagellum longer than 

 wide, the 2nd joint nearly twice as long as the 1st. The pronotum 

 is more or less coarsely but shallowly strigose, with a few large 

 shallow punctures at the side ; the mesonotum, which is similarly 

 sculptured, is as long as wide, fairly round, and slopes backwards in 

 such a way that the pro- and mesonotum together form a curve, 

 moderately bowed from front to back. The thorax is not deeply 

 constricted between the meso- and epinotum. The latter is long, 

 about as long as the pro- and mesonotum together, and its dorsum 

 rises gradually backwards and then falls rather abruptly towards the 

 rounded boundary between it and the declivity; the dorsum is 

 irregularly rugose, the declivity coarsely and transversely striate ; 

 the sides of the meso- and epithorax are obliquely striate. 



The node of the petiole is finely wrinkled and sparsely punctured ; 

 it is longer than wide, much wider and higher behind than in front, 

 the posterior face vertical, flat and transversely striate. The abdo- 

 men is almost smooth, barely constricted between the 1st and 2nd 

 segments. Legs long and thin, the claws distinctly pectinate.

The male of the type form is not known, but since the male sex 

 usually varies but little in sub-species and varieties, it may be of 

 some assistance to the student to be able to refer to the description 

 by Forel of the race erythraea, Emery, which is herewith appended.
