well as in several others, a remarkable variation in the con- 

 tour of the eye, which might readily be mistaken for a 

 specific character. In most specimens ,^ g the eyes are as 

 smooth as they usually are in mature Ilymenoptera; but in 

 3 (j" 5 2 the surface of the eye is elevated in a number of 

 large rounded whitish or gray tubercles— giving it a very 

 singular appearance.

I possess also 8 (5" 33 g captured at large, which should 

 probably be referred to Say's species . I have been unable to 

 identify Eurytoma orbiculata, S.ay, described in ^ se.x only, 

 and the laws of coloration seem to me to forbid the existence 

 of any species of Eurytoma with such legs as S.^y describes 

 in this species. According to him, the legs ai e ' 'honey-yel- 

 low, with the thighs, except at their origin and extremity, 

 black." Now, 1st, If the thighs were much marked with 

 black, the coxa; would necessarily also be more or less black, 

 whereas they are by implication described as "honey-yel- 

 low;" 2nd, if the front femora were mostly black, as he 

 describes them, the hind tibiie would most probably be more 

 or less black. For it is a very general law in ChalcidUlcc
