Ilymenopterous Genus Tiphia. 131

I do not understand why Dalla Torre sinks SpinolaV 

 name, which has priority over Smith's. As (Smith's name 

 has to sink, I propose T.bomeensis for that species. I regard 

 specimens from the ontiuent of Asia which have been 

 refeired to Jiavipennis as distinct.

The differences in sculpture seem to bd too slight to be of 

 specific importance. 



Genus Pcecilotiphia, Cam. 



As I have before said, I agree with Ashmead in regarding 

 this genus as allied to Myzine rather than to Tiphia. 

 Although there are only two cubital cells as in Tiphia^ the 

 second transverse cubital nervure seems to be missing, not 

 the first as in Tiphia. The female is unknown. 



In spite of some differences in neuration, I am inclined to 

 think that the following species are nearly allied to this 

 genus : Methoca rngosa, Cam., in which there are two cubital 

 cells, and Myzine dimidiaticornis, Bingh., in which there are 

 three. They show many points in common, and are not well 

 placed in the genera to which the authors have assigned 

 them. The claws of M. dimidiaticornis , however, are bifid, 

 not simple, which together with the difference in neuration 

 may be sufficient to form a new genus tor it, but it is better 

 to wait till the female is known. The antennas of all three 

 species differ widely from those of Myzine, and the pronotura 

 is much longer.
