HYMENOPTERA NEW TO CEYLON, WITH DESCRIPTIONS 



OF NEW SPECIES. 



By 0. S. WiCKWAR, F.E.S. 

 With Plate ; and Appendix by Col. Bingham. 



THESE notes will deal with the tribes and families described in 

 Col. Bingham's work on the Hymenoptera of British India, ■ 

 Vols. I. and II. (Fauna of British India Series). 



The following list, compiled from the volumes in question, gives 

 four tribes with their respective families and relative number of 

 species, showing a total of 193 species recorded from Ceylon, 59 of 

 which are endemic, against a total of 30 species recorded in Sir 

 Emerson Tennent's work on Ceylon about fifty years ago. 



The fact tliat many of our commonest species are not recorded 

 from Ceylon will sliow what little attention has hitherto been given 

 by collectors to Ceylonese Hymenoptera. 



I have to thank Dr. A. Willey , the Director of the Colombo Museum, 

 who has kindly placed at my disposal the Museum collection. My 

 thanks are also due to Messrs. E. E. Green, F. M. Mackwood, Col. 

 N. Manders, R.A.M.C.,and Mr. Thos. Bainbrigge Fletcher for the 

 gift of several specimens. Above all, I am indebted to Col. C. T. 

 Bingham for his generous assistance at all times, and for ready help 

 proffered in verifying my identifications and checking several 

 descriptions. It is proposed to continue these notes from time to 

 time when sufficient information and material have accumulated.
