HYMENOPTERA OF THE BOMBAY PRESIDENCY. 659 



a spot behind tegulse, 2 spots at base of scutellum, apical slope of scutellum, 

 pleura;, the sides of 1st abdominal segment, the apices and bases of the 

 segments narrowly, their sides widely, a spot in the centre of the 1st ventral 

 and the apices of the others widely covered with white pubescence, as are also 

 the greater part of the legs. Wings hyaline, tinged broadly with violaceous 

 at the apex. $ . 



Length 8 mm. 



Matheran. March. 



Scutellum broadly rounded posteriorly, the teeth stout, bluntly pointed 

 broader laterally than above. Ventral plate of apical segment large, spoon- 

 shaped, with a broad rounded upper border, keeled on the inner edge. The 

 apex of the apical dorsal segment is strongly, coarsely punctured, depressed and 

 with a smooth, stout keel in the centre of the depression. There is a trans- 

 verse, somewhat broad keel near the apex of the 2nd and 3rd segments, 

 bordered before and behind by a smooth, shallow furrow. Frontal keel broad, 

 smooth on lower half only. 



Puncturation on the head strong and close, on the scutellum it is closer, 

 running into reticulations. The apical ventral segment projects half the length 

 of the dorsal beyond the apex of the latter. The part between the broad frontal 

 keel and the ocelli is depressed. 



In Bingham's key this little species would come into A. b, : it cannot be 

 confounded with fuscipennls or angulatus.
