224 PROC. ENT. SOC. WASH., VOL. 26, NO. 9, DEC, 1924 "I find also under date of September 16th a request for the 13th and 14th reports of the State Entomologist's Office from the State Library of Massachu-setts, showing that a knowledge of the appearance of the 14th report had begun to become general by that date. "I am enclosing these letters, which you will kindly return when you have verified their dates." Upon the receipt of this interesting and valuable information the writer submitted his evidence to Mr. Gahan, in response to which he replied as follows: "Your registered letter of March 1 received, and I was very glad to see the interesting correspondence sent by Dr. Forbes. The evidence he submits seems to be very conclusive that the description oi Pteromalus fiihipes Forbes ante-dates the description of Merisus subapterns Riley. This being the case, of couvse fulvipes is the specific name which should be used." "P. S.: Although the dates printed on the signatures in which Riley's descrip-tion oi subapterus appeared are Sept. 14th and 17th as Forbes states, the records in the office of Correspondence and Documents of the U. S. National Museum indicate that the papers were not received from the Government Printing Office until Oct. 3. A. B. G." Although the author regrets to see the name subapterus^ which is so applicable to the species, give way to the name fulvipes, yet the change must be made, if the rule of priority is to be strictly adhered to, and credit given the one to whom it rightly belongs. In view of the fact that Girault erected the genus Nemi-cromelus citing Merisus subapterus Riley as the genotype which has now proven to be a synonym of Pteromalus fulvipes Forbes, the proper name to be applied to this common species of Hessian fly parasite is Nemicromelus fulvipes (Forbes). THE SYSTEMATIC POSITION OF THE GENUS HARMOLITA MOTSCHULSKY WITH ADDITIONAL NOTES (HYMENOPTERA). By a. B. Gahan, U. S. Bureau of Entomology. Messrs. W. J. Phillips and W. T. Emery in 1919^ published a "Revision of the Chalcid-Flies of the Genus Harmolita of America North of Mexico." Largely upon the advice of Mr. J. C. Crawford and the writer, the authors used the generic name Harmolita Motschulsky for this group of insects which constitutes the well known jointworms of grasses and grains previously going under the generic name Isosoma Walker. The name Isosoma was shown to be preoccupied, having been used by Billberg (1820) in Coleoptera. Dr. Ashmead, in his "Classi-fication of the Chalcid Flies," had pointed out that Mot->Proc. U. S. Nat.
