59. Eiirytoiua soleiiozoplierise u. sp. — % 9. Length .08 to .10 inch. 

 Black, less coarsely pniictured than usual, face and thorax covered with a silvery- 

 gray pubescence. In shape it somewhat resembles E. stiidiosa Say, but the black, 

 polished abdomen is much more compressed, and the projecting valves longer, 

 and its tip is only slightly pubescent. The antennse are brown-black, excepting 

 scape at base, which is pale ; in outline the antennae are subclavate, 8-joiuted, 

 the joints of club not distinctly separable, the joints of flagellum are rounded, 

 the flr.st being slightly longer than broad. The legs are brownish- yellow, the 

 posterior femora brown or black, excepting tips and a brown line on anterior and 

 middle pairs, and on all the tibise, excejiting the anterior pair in the male. The 

 peduncle of the male is very long, as long as the anterior femora. 



Hdb. — Toronto, Canada. Desci-ibed from specimens sent me by 

 Mr. Wm. Brodie, and reared from the cynipidous gnW Solenozopheria 

 vaccinii Ashni. 



Its finer punctured surface, denser pubesceiice, large peduncle in 

 the S , differently colored antennse and legs, will readily distinguish 

 it from E. sfudiosa Say, to which it shows affinity.

Dr. Fitch, in his " Fifth Report on Noxious and other In.sects of 

 New York" described a chalcid reared from his oak gall Cynips 

 lance = Andricus flocci Walsh, which he called Spalangia querci-lance 

 and a variety of it dorsalis, which I am satisfied is nothing but a 

 Decatoma, as from this same gall I have reared nothing but Deca- 

 tomce, two varieties agreeing in all particulars with this so called 

 Spalav.gia, and which I shall show were afterwards described by Mr. 

 Walsh as two distinct species, reared from galls on the white oak. 



Let us compare descriptions in parallel columns:

Black, with the face, antennae, sides 

 of collar, whitish or greenish-yellow. 

 Its cubital head, which is about as long 

 as wide indicates its relationship to 

 l^palangia, thoticih in some respects it does 

 vot appear to fidly coincide with the char- 

 acters assigned to this genus. The ab- 

 domen is smooth and polished, its un- 

 derside of a tawny red color, and is 

 separated from the thorax by a pedicel. 



Legs whitish or greenish -vel low.
