ADDITIONS AND CORRECTIONS TO "THE TYPE-SPE-CIES OF THE GENERA OF THE CYNIPOIDEA OR THE GALL WASPS AND PARASITIC CYNIPOIDS." By S. A. RoHWER and Margaret M. Fagan, Bureau of Entomology, United States Department of Agriculture. INTRODUCTION. In the paper on The Type Species of the Genera of the Cynipoidea, or the Gall Wasps and Parasitic Cynipoids, published in the Pro-ceedings of the U. S. National Museum/ there are several omissions and errors requiring correction. These corrections, which were called to our attention by the kind-ness of Mr. L. H. Weld, include the addition of a few generic names, several overlooked type designations, and corrections of dates, page references, and orthography. In the case of the page references for the genotypes transferred by Dalla Torre and Kieffer to other genera, the pages quoted in the paper refer to the page of the synonymy of the genus and not to the page of the transfer of the type-species. CORRECTIONS. Page 360 : Allocynips Kieffer. Correct reference is : Phil. Journ. Sci., vol. 9, sec. D, 191-1, p. 185. Page 362 : Aulacidca Ashmend. Clinnge " Present designation " to Original designation. Auloxysta, sliould read : Auloxysta TiioMsoN=(Bothrioxysta Kieffer). Opuse. Eutora., P. 8, 3887, \\. 811. Seven species. Type. — Auloxysta nigripes Thomson (Designated by Ashmead, 1903, p. 142.) [Type. — Auloxysta stricta Thomson. (Rohwer and Fagau 1917.)] Isogeuotypic with Bothrioxysta Kieffer. Genotype placed in Fhae-noglypMs Forster by Dalla Torre and Kieffer, 1910, p. 294. Belenocnema should be: Belonocnema. Both spellings occurred in the original discussion of the genus, but inasnuich as JIayr himself pointed out the error of the spelling Belenocnema it is better to use Belonocnema. Bothrioxysta should read : (Bothrioxysta KiEFFEB)=Aiiloxysta Thomson. Bull. Soc. Hist. Nat. IMetz (2), vol. 10. 1902, p. 11. Type.— Auloxysta nigripes Thomson. (Rohwer and Fagan, 1917.) Isogeuotypic with Auloxysta Thomson. Genotype placed in Phae-noglyphis by Dalla Torre and Kieffer, 1910, p. 294. 1 Vol. 53, June 6, 1917, pp. 357-380. Proceedings U. S. National Museum.
