SERPHOID AND CHALCIDOID PARASITES OF THE HESSIAN FLY 65 

 Family PTEROMALIDAE 



AMBLYMERUS MAYETIOLAE (Gahan) 10 



(Fig. 15) 



Eutelus mayetiolae Gahan, U.S. Natl. Mus. Proc. 55: 128, 1919; Packard 

 U.S. Dept. Agr. Tech. Bui. 81 : 14, 1928. 



Figure 15. — Amblymerus mayetiolae Gahan: A, Adult female; B, antenna of female 

 C, antenna of male. A, x 26. 



DESCRIPTION 



The immargined occiput, 5- jointed funicle, neckless propodeum, 

 hyaline wings, wholly metallic abdomen, pale legs, and the black 

 antennal club of the male distinguish Amblymerus mayetiolae from 

 all the related North American parasites of the fly. 



Female. — Length 1.5 to 2.25 mm. Head very slightly broader than thorax, 

 fully three times as broad as thick antero-posteriorly at the middle, the occiput 



10 Gahan and Fagan (U.S. Natl. Mus. Bui. 124: 10, 64, 1923) pointed out that 

 Amblymerus Walker and Eutelus Walker have the same species as genotype. Since 

 Amblymerus has page precedence in publication, that name should be used in place of 

 Eutelus. Hence Eutelus mayetiolae Gahan becomes Amblymerus mayetiolae.
