1 66 Cameron, Hymenoptera Orientalia. 



distinctly appendiculated, triangular ; the apical transverse 

 cubital nervure curved ; the recurrent nervure is received 

 shortly beyond the middle. Petiole shining, impunctate, 

 the base depressed ; the apex of the depression rounded ; 

 its sides narrowly keeled ; the keels obliquely continued to 

 shortly beyond the middle ; the second segment is broadly 

 depressed laterally at the base ; the transverse furrow 

 wide. The third, fourth, and fifth segments are closely 

 and rather strongly punctured ; the sixth obscurely punc- 

 tured ; the apical smooth ; the transverse furrows are 

 distinct, moderately wide and deep, and obscurely crenu- 

 lated. On either side of the petiole in the middle are two 

 irregular marks, wider than they are long : there are no 

 marks on the second ; there are two large marks on the 

 base of the third ; on the base of the fourth are two small 

 marks ; on the base of the fifth two large marks broader 

 than they are long ; on the base of the penultimate are two 

 larger marks. 



b. Abdomen impunctate. 



The central area on the median segment square, the basal 

 two segments each with two black marks. P. khasiana. 



The central area on the median segment wider than it is 

 long, wider at the base than at the apex ; the basal two 

 segments immaculate. P. indubia. 



PiMPLA INDUBIA, Sp. nov. 



Long. 15 mm. 



Similar in coloration to P. lepcha, having only 6 marks 

 on the abdomen ; but that differs in having the middle 

 segments of the abdomen strongly and distinctly punc- 

 tured, and in having the middle basal area of the median 

 segment distinctly narrowed from the middle to the apex, 

 whereas in the present species it becomes gradually
