PHYTOPHAGOUS AND PARASITIC HYMENOPTBRA. 69 



paper doubtfully referred to Microgaster. The same remark 

 applies to the species of Microgaster described by "Walker. The 

 systematic position of some of the genera described by the Russian 

 Hymenopterist is also doubtful in some cases. Thus his genus 

 OalUopterotna, referred by him to the Iclineumonidce, belongs to 

 the Encyrtidw (fihalcididce) according to that eminent authority 

 Dr. Wm. H. Ashmead, cf. Proc. U. S. Nat. Mus. XXIIL, 152. The 

 late Mr. Francis Walker described (Ann. Mag. Nat. Hist. 1860, 

 VI.), a number of species and some new genera, none of which I 

 have been able to identify, nor has Dr. Ashmead, /.c.,been able to 

 refer them to their proper tribes. I do not know where Walker's 

 types are. Apparently they are not in the British Museum, 

 otherwise Col. C. T. Bingham would have described the aculeates 

 in his work on the Aculeate Hymenoptera of British India and 

 Ceylon. In that work he has merely reproduced Walker's descrip- 

 tions. I have myself (Manchester Memoirs) described a few species 

 taken by Mr. G. A. J. Rothney and by Col. Yerbury, and in Proc. 

 U. S. Nat. Mus. XVIII., Dr. Ashmead has described some species, 

 mostly reared from Lepidoptera and Coccidse, taken or bred by 

 Mr. Green. And some species have been described by J. 0. 

 Westwood in his Thesaurus Entomologicus Oxouiensis. From 

 what I have said it is evident that our information regarding the 

 Hymenoptera of Ceylon is of a very restricted nature — a remark 

 that applies with even more force to Southern India.
