wings fusoo-liyaline with a small black stigmal dot, and with the last two-thirds 

 of the outer costal edge black, other veins brownish ; legs yellowish, anterior and 

 middle femora infuscated in middle, the thick oval posterior femora yellowish- 

 brown, a broad dark medio band occupying one-third or more of the surface, the 

 band is also extended over on to the tibire as may be seen when these are drawn 

 up into the femoral groove, the latter armed with about eighteen small but regular 

 teeth, tarsi pale yellowish, ungues black. 



Captured on rose galls. I do not think it parasitic on the galls ; 

 it was probably attracted there by some larvte.

Eurytonia bicolor Walsh, Amer. Eutom. vol. ii, p. 298, 1869. 



Eurytoina priiiiicola Walsh, loc. cit. fig. 1. 



This species I have bred from the cynipidous oak gall ('. q. riigosa 

 Ashmead. It agrees very well with Walsh's description excepting its 

 larger size and the whole abdomen being black. He says : " $ with the 

 bng medial or fifth joint always rufous and the fourth generally piceous." 

 I am therefore in doubt whether the determination is correct.

Walsh was unable to identify this species and seemed to think the 

 "laws of coloration forbid its existence." Neither Walsh's want of suc- 

 cess in finding it, nor are the laws of coloration sufficiently demonstrated, 

 to warrant its rejection.
