CORRECTIONS IN EVANIID^, ETC. 



BY J. CHESTER BRADLEY, ITHACA, N. Y. 



In Schletterer's "Die Hymenopteren Gruppe der Evaniiden," Annalen 

 d. k. k. Nath. Hofmuseum Wien, IV., p. 311, read trochanterata, Cameron, 

 for trochanterica, Cameron. Page 338, the locality for Evania seminibra, 

 Cresson, should be Cuba. Page 1 18, in synonymy oi Evania, date 1829, 

 after *' Evania, Curtis," should come the following reference : " Brachy- 

 gasier, Stephens, Systematic Catalogue of British Insects. I. p. 343, 1829. 

 On page 143, under synonymy of Evania minuta, the same reference, 

 Brachygasier mifiiitus, Stephens, should be put in after Evania fulvipes, 

 Curtis. In Dr. C. G. De Dalla Torre's " Catalogus Hymenopterum," 

 Vol. III., p. 1076, midtr Evania, Brachygasier, Leach, Edinb. Encycl., 

 18 1 7, should be struck out and Brachygasier, Stephens, Syst. Cat. of Brit. 

 Insects, 1S29, replace it. Leach, in the reference given simply under a 

 description of Evania ininuius, states as a synonym " Brachygasier 

 mi7iuius. Leach, Mss.," which is not even an attempt, let alone sufficient 

 to establish a genusf So a corresponding change should be made aftt:r 

 Eiania tninuia, Lamarck, on page 1082. Thus we have 1829 as the 

 date of establishment of the generic name " Brachygasier,^' but in 1826 it 

 was used for a genus of Diptera by Meigen. Hence it falls as a homonym, 

 and as the genus is to-day recognized, I propose the change: 



Brachygaster, Stephens, name preoc. = Sem^odogaster, new name. . 

 In plate I.. Dr. Schletterer, has represented (figs. 5 a-e) veins that are 

 atrophied and visible only as mere traces. This is apt to cause confusion, 

 as they are so strongly drawn as to give the impression of distinct veins. 

 E. amazonica (fig. 5 e) can scarcely show a trace of an extra vein between 

 the transverse discoidal and transverso-medial veins. Such a condition is 

 not found in any Hymenoptera higher than Phytophaga, and Dr. Schletterer 

 must have mistaken a mere coloration for a trace of a vein. The more 

 correct figuration is shown in Kieffer's " Evaniids"," in Wytsman's 

 " Genera Insectorum," plate I., fig. 7. 



Kieffer, in Zeitschr. fur Hym. u. Dipt. III., p. iii, establishes 

 Pseudevania for E. irochanieraia, Cameron, and marginaia, Cameron, 

 without giving any characters. The two are utterly unlike and generically 



February, 1905.
