the posterior angles slightly rounded and the posterior margin straight. 

 Frontal area wide and triangular. Clypeus very convex, subcarinate. 

 The scape extends beyond the hind margin by quite one-third of 

 its length (shorter in Steingroceri). Mandibles closely and evenly 

 striate, armed with 6 or 7 strong black teeth, the apical tooth 

 twice as long as the others. Thorax like that of Steingroceri, but 

 the promesonotum is a little more convex, the dorsum of the epino- 

 tum shorter, with the stigmatic orifices more prominent at the 

 posterior angles. Scale rounded, or barely emarginate at the summit, 

 erect, as high as in Steingroceri. Abdomen dilated. 



Q minor. More shining than the ^ major; the sculpture more 

 effaced; head a little longer than wide; the scape extends beyond 

 the hind margin by half its length. Promesonotum less convex than 

 in the ^ major. The stigmata on the epinotum even more promi- 

 nent at the posterior angles, the latter more accentuated. Scale 

 thick, not emarginate above, abdomen smaller, otherwise like the 

 ^ major. It also differs from Steingrijoeri in colour, with which it 

 is closely allied".

(f. 40-11*5 mm. Thorax, scale and antennae pale yellowish 

 brown, the legs brownish ochreous, head blackish, mandibles ochreous 

 with black teeth, the abdomen in greater part dirty brownish yellow, 

 with indistinct darker or brownish bands dilated in the middle on 

 the apical margins, the base of the 1st segment brown. The pubes- 

 cence on the head and thorax less plentiful than in custodiens, the 

 pubescence on the abdomen directed straight backwards, not undu- 

 late as in custodiens. This species bears a very great resemblance 

 to custodiens, but differs from it as follows. 



The head is longer, or a trifle longer than wide behind the eyes, 

 the width behind the eyes is only one-fourth greater than the width 

 of the anterior margin, (a little more than one-third in custodiens). 

 The mandibles are shining, only aciculate and not sharply striate 

 as in the other species, and with much blunter teeth. The eyes 

 are a little smaller but more prominent. The scapes are nearly 

 straight, not curved at the distal third as in custodiens. The thorax 

 is lower, the dorsum of the mesonotum and scutellum not raised 

 much above the base of the epinotum. The mesonotum is a little
