FOSSORIAL WASPS. 613 



All the dorsal and ventral segments have broad chitinous bands 

 of brown, covered on the four basal dorsal segments with golden 

 pnbescence. 



Two females and one male in the British Museum, all from 

 Smith's collection.

The type is unique in the British Museum, without any data 

 to show whence it was received. At one time I confused it with 

 2ndchrinum, but it differs as pointed out in the description of 

 that species. There is a minute tubei-cle on each side of the 

 mesostei'num, as in auratus and aniveosericeum.

$ . Nigra ;, mandibulis, antennis articulis quinque basalibus, 

 tegulis, femoribus apice, tibiis tarsisque ferrugineis ; segmentis 

 dorsalibns 3-6, ventralibus 2-6 fascia apicali bruunea ; segmento 

 dorsali primo fascia apicali aureo-pvibescente ; fronte dense, 

 thoi-ace segmentoque mediano sparsius aureo-pilosis ; alis hya-

S .- Feminse similis. 



Long., 5 13 mm., cJ 10 mm. 



9 . Clypeus very broadly rounded or subtruncate at the apex, 

 clothed with golden pubescence, which extends on the front as 

 high as the emargination of the eyes. Second joint of the 

 flagellum longer than the third, about equal in length to the 

 first and third combined. Posterior ocelli a little fui'ther from 

 each other than from the eyes, separated from the eyes by a 

 distance slightly exceeding their own diameter ; eyes more than 

 half as far again from each other on the clypeus as on the 

 vertex. Front somewhat convex, the frontal sulcus indistinct ; 

 the punctures of the head microscopic. Thorax rather more 

 distinctly punctured, the pronotum and postscutellum clothed 

 with golden pubescence. Mesosternum with a minute tubercle 

 on each side. Median segment short and broad, finely punctured, 

 clothed with pale golden pubescence ; the median sulcus distinct, 

 but shallow, the median carina not reaching the apex; the 

 apical slope coarsely transversely striated, with a deep median 

 sulcus. Abdomen microscopically punctured ; the basal segment 

 short and broad, a little depressed at the apex, with a broad 

 band of golden pubescence, second segment without an apical 

 band of pubescence, the bands on the third and fourth segments 

 fairly broad. Recurrent nervures intei-stitial with the trans- 

 verse cubital nervures ; second abscissa of the radius longer than 

 the petiole of the second cubital cell ; transverse median nervure 

 received beyond the basal nervure. 



(5 . Clypeus with a small spine in the middle of the apical
