The points requiring attention prior to spraying, to ensure the best 

 results, are emphasised. For potatoes a spray of calcium arsenate, 

 with the addition of 5 lb. of hydrated lime to 40 gals, of water, is 

 advocated in preference to Paris green.

As a result of the examination of the male genitalia, it is stated 

 that Pyyausta cajfycii, Flint & Malloch {R.A.E., A, viii, 450], is a 

 synonym of Loxostege similalis, Gn. 



The species figured under the name of P. ohumbratalis. Led., is 

 P. ainsliei, Heinr. The precise identity of P. obumbratalis. Led., 

 cannot at present be ascertained.

 Chalcidoidea (Hymenoptera). — Proc. Ent. Soc. Washington, D.C.,

The Chalcids, the synonymy of which is discussed, include the 

 Pteromalids, LariopJiagus distinguendus, Foerst., the synonyms of which 

 include Meraporus calandrae. How., and M. utibilis, Tuck. ; and Meri- 

 sus isosomatis of authors, which is not Stictonotus isosomatis, K\\ey, 

 but M. febriculosus, Gir. The latter is a parasite of various species 

 of Harniolita and of Mayctiola destructor (Hessian fiy). Its distribution 

 ranges from Maryland to Kansas, but it will probably be found to 

 occur over the whole of the United States and Canada where wheat 

 is attacked by joint- worms and M. destructor.
