Unfortunately the writer has been able to examine only one speci- 

 men of flaminms from Europe, so that the identity of eytehveinii 

 (Ratzeburg) could not be investigated fully. Obviously the two 

 forms are much alike, flaminius being described as having the middle 

 tarsi black, the hind tai-si and middle tibial spur white, and eytel- 

 iveinii as having the discoloration of the tarsi just reversed. Mayr 

 considered them to be forms of one species, and apparently had 

 examined intermediate specimens. The specimen in the hands of 

 the writer may also be considered intermediate since the hind tarsi 

 are black, the middle pair almost entirely blackish underneath, and 

 the tibial spur dark brown or in part blackish. Nevertheless no such 

 variation in the color of the tarsi has been observed in specimens 

 from other parts of the world, the hind tai-si being uniformly dark 

 and the middle pair white or pale yellowish in all specimens exam- 

 ined from such remotely separated regions as South Africa, China, 

 and Australia. 



Girauit's species orci and microgaster can not be separated from 

 fiar.iinius, as they are based on too variable characters. The com- 

 parative lengths of pedicel and first two funicle joints, of the stigmal 

 and postmarginal veins, and the slight variations in color noted above 

 can not be relied upon to distinguish species in this group. In gen- 

 eral it may be said that in very small specimens the fii-st funicle joint 

 is usually no longer than thick, and becomes gradual!}^ longer with 

 increase in size.

This species is known to the writer only by description. In colora- 

 tion it recalls certain forms of terminalis of North America, such as
