288 SPHEGIDJE. 



lateral angles and sides of the last, the pro- and mesopleurse, and 

 broad transverse bands on tbe lst-5tb abdominal segments above 

 sulphur-yellow, the band on the basal segment with four deep 

 rounded emarginations anteriorly, and the bands on all the seg- 

 ments bisinuate posteriorly ; two small spots on the clypeus, the 

 middle of the pronotum anteriorly, some irregular marks on the 

 sides of the thorax, and lateral spots on the bands of the 2nd-5th 

 abdominal segments bla«;k ; legs variegated yellow and black ; 

 wines slightly flavo-hyaline, nervures brownish, tegulse yellow. 



c? similar, the 8th-10th joints of the antennae spiuose, and the 

 11th and 12th excavated beneath, the apical half of the intermediate 

 femora serrate or dentate posteriorly, the apical segment of the 

 abdomen with the lateral margins waved, scarcely dentate (in the 

 2 these are straight), the 6th abdominal segment with a trans- 

 verse yellow band.

5 . Head and thorax very finely and closely punctured, pubes- 

 cent ; abdomen shining, the surface very finely aciculate ; the eyes 

 slightly but distinctly divergent below ; the apical segment of the 

 abdomen triangular, punctured, the sides sinuated, the apex rounded, 

 with a very slight short medial carina. Black ; the labrum, the 

 anterior margin broadly of the clypeus, a line behind the eyes, the 

 pronotum, a U-shaped mark on the mesonotum, a line over the 

 tegute. a curved line on the scutellum, another shorter one on the 

 postscutellum, a third broader one, produced triangularly back in 

 the middle on the medixm segment, the posterior lateral 'angles of 

 the same, and more or less broad transverse bands on the basal 

 four segments of the abdomen, with an oval spot on the sides 

 of the 5th segment, bright yellow ; these transverse bands on the 

 abdomen vary in different specimens in width, and in the manner 

 in which their margins are festooned or intruded on by the black 

 ground-colour, but the band on the 2nd segment has always, on 

 the 3rd sometimes, a black obliquely placed spot on each side ; 

 leo-s yellow, variegated with black ; wings hyaline, nervures and 

 tegulse testaceous. 



S . In the two specimens I have seen the 6th-8th joints of the 

 anterinsB are spinose beneath, the 10th-12th joints excavate, and 

 the apical joint curved, the intermediate femora dentate posteriorly, 

 the dorsal plate of the apical segment emarginate at apex, and the 

 clypeus and face to the posterior ocellus yellow. Otherwise the 

 two sexes are similar.
