NEW SPECIES OF INDIAN HYMENOPTERA. 18 



single furrow 5 median segment rounded posteriorly, abdomen rather 

 longer than thorax, petiole very short, second segment the longest, 

 second and third segments constricted at apex. Black ; the scape of the 

 antennae, tubercles, apex of all the femora, the greater part of the tibia*, 

 and all the tarsi more or less yellow ■ the first two joints of the flagellum 

 testaceous ; wings hyaline and iridescent, nervures dark brown, 

 ■tegulse yellowish ; clypeus, front, and cheeks with short, stiff, silvery 

 pubescence. 



Long, 5 mm. 



Habitat : Kangra Valley, Punjab, 4,500ft ; two specimens sent me 

 by Mr. G. C. Dudgeon. 



This species is easily distinguished from P. levipes by its smaller 

 size, and by the median segment being reticulate. It is near to P. 

 rdiculatus (Cam.), but has no keels on the head.

 posterior ocelli further apart from one another than from the margin 

 of eyes ; antennae short, stout, the third joint of the flagellum slightly 

 the longest, remainder subequal ; median segment narrowed and round- 

 ed posteriorly. Black ; the mandibles, except their tips, the scape of 

 the antennae, apex of the femora, and the whole of the tibiae and tarsi 

 pale yellow ; the flagellum of the antennae red ; clypeus and front (#) 

 with short, thick, silvery pubescence ; wings hyaline and iridescent,

Two species of this genus have been described from India by Mr. 

 Cameron, viz. D. geniculatus and D. striolatus. From the former the 

 present species may be distinguished by the tibiae and tarsi beino- 

 yellow : from the latter by the antennae being red, not black. The 

 only European species with yellow mandibles, D. minutus (Fabr.) has 

 also the antennae black.
