widest just behind the eyes, the sides in front of the eyes fairly straight 

 and moderately convergent anteriorly ; behind the eyes the head is 

 semicircular. The posterior margin as wide as the anterior and feebly 

 convex. Eyes not very large. The scapes extend beyond the hind 

 margin by half their length, flattened as in the $. Masticatory margins 

 of the mandibles convex, with an apical tooth only. Mesonotum 

 vertical in front, with two median and impressed shining lines on the 

 vertical face, the latter merges by a curve into the flat upper and 

 posterior part. Scutellum gibbous, higher than the meso- and 

 epinotum. The dorsum and declivity of the epinotum form a con- 

 tinuous curve, the declivity vertical and longer than the dorsum. 

 Scale of petiole subconical in lateral profile, hardly longer at the base 

 than high. Seen from above, the anterior face is oblique, concave 

 transversely, the posterior face convex transversely, feebly so ver- 

 tically, the dorsal edge widely emarginate. Wings strongly tinged 

 with ochreous yellow, nervures brown, stigma brownish black.

All the nests which I have seen have been situated under large stones, 

 with a large heap of excavated soil surrounding the entrance in a 

 semicircle, but not forming a distinct half-crater. A very pugnacious 

 species.

"21, 12-12*5 mm. Head almost like that of maculatus-sanctus, very 

 wide behind and emarginate, narrow in front, with very convex sides. 

 Mandibles with 7 or 8 teeth, somewhat more shining in front than 

 in the £ minor and partly striate. Clypeus sharply carinate, with 

 a rectangular lobe. Scape flattened and widened apically as in the 

 type species. Legs, sculpture and pilosity also similar. The decum- 

 bent pubescence decidedly less plentiful, not forming a greyish 

 bloom. Colour also black, but the two yellow spots on the cheeks 

 entirely absent. Mandibles brownish red, the base brown." 



Bothaville, O.F.S. (Dr. Brauns). 



The 2j_ of the type of the species also lacks the yellow spots on the 

 cheeks. The differences between the two forms appear to me to be 

 very slight.
