subparallel, not extending beyond the anterior third of the head. 

 Frontal area rather large. Clypetis feebly carinate in the middle. 

 Mandibles sparsely punctured and shining, the basal half striate. 

 The scapes extend beyond the posterior margin of the head by one and 

 a-half times their apical width. Pro-mesonotal suture obsolete (in 

 Forel's description erroneously stated to be distinct). The posterior 

 lateral angles of the pronotum bear a minute tubercle, not easily seen. 

 Meso-epinotal suture distinct. Mesonotum shallowly impressed 

 transversely in the middle. Dorsum of epinotum flat, one and a-half 

 times longer than wide, bearing two minute and vertical teeth, much 

 shorter than the interval between their bases. Declivity shorter than 

 the dorsum. Dorsal edge of the first node of petiole not emarginate, 

 the second node one-third wider than long, convex in front, the sides 

 obtusely angular, sometimes with the angles produced into short 

 truncated cones. Abdomen subtruncate at the base, longer than wide. 

 $. 57 mm. (hitherto undescribed). Brownish-black; tarsi and 

 apices of the femora and tibiae brownish-yellow, mandibles ferrugi- 

 nous. Pilosity and pubescence as in the 1/ . Head longitudinally and 

 rather closely striato-rugose, the spaces between the striae rugulose 

 and dull, except between the frontal carinae, where they are slightly 

 shining. Mandibles more strongly punctured than in the 1/ . Meso- 

 notum very closely and finely striate and dull, the striae converging 

 posteriorly ; a median patch in front and a lateral one on each side over 

 the parapsidal sutures are smooth and shining. Scutellum smooth, 

 shining and very sparsely punctured. Epinotum smooth and shining 

 in the middle, rugulose at the sides. Nodes dull and rugulose. 

 Abdomen moderately shining, the first segment and the apical margins 

 of the following segments finely punctured. Head as wide as long, a 

 trifle wider behind than in front, the posterior margin straight, the 

 sides parallel or very slightly convex in their posterior third, the 

 posterior angles moderately acute. Clypeus and antennae as in the 1/ , 

 the frontal carinae longer. Eyes not very large, ocelli slightly 

 depressed. Mesonotum flat, convex only in front, a little wider than 

 long. Scutellum semicircular, less than half as long as the mesonotum. 

 Dorsum of epinotum obsolete in the middle, forming a continuous 

 vertical plane with the declivity. Epinotal teeth stout, triangular, 

 shorter than their basal width. Posterior-dorsal face of the first node 

 wider than long, 2nd node nearly three times wider than long, the 

 lateral spines longer and thinner than in the 1/ . Abdomen one and 

 a-half to one and two-thirds longer than wide, the sides subparallel. 

 Wings feebly fuscous, nervures pale yellow, stigma pale brownish- 

 yellow.
