NEW AND LITTLE-KNOWN SPECIES OF 207 



JNDO-MALAYAN HYMENOPTERA. 



hundreds of specimens, and in most cases series of many species of 

 each genusj still I have had only the materials afforded by my own 

 collection to judge from. My collection is fairly extensive, but the 

 data drawn from it alone may hereafter, with more material at com- 

 mand, prove to be faulty. This, however, is certain that, though I have 

 been collecting steadily for ten years in Burma and Tenasserim, and 

 have had, moreover, large collections sent to me from various parts 

 of India, Ceylon, the Straits Settlements and Sumatra, following the 

 keys given below^ I have had no difficulty in assigning every 

 pompilid insect I have so far come across to what I consider its 

 proper genus. 



■The classification followed is that of Kohl, in "Die Gattungen der 

 Pompiliden," Verb, der K. K. Zool. Bot. Ges. Wien, 1884.
