doubtful of the correctness of the former identification, Mr. Schaeffer sent specimens 

 of this species to Mr. J. Weise, of Berlin, who pronounced them identical with the 

 European species except that they lack the ferrugineous scutellar spot. Eurypepla 

 jamaicensis Linn, is another species new to our fauna taken in Key West, Florida, 

 and sent to him by Mr. Schwarz. The distinction between some of the closely allied 

 species was given. 



Mr. C. W. Leng gave an interesting account of the collecting trip which he and 

 Dr. Love took in West Virginia last summer. 



Meeting of May 3, 1904. 



Held at the American Museum of Natural History. In the absence of the Pres- 

 ident, the Vice-president, Mr. Leng, occuoied the chair with twelve members and 

 one visitor present. 



The treasurer, Mr. Davis, reported a balance of ^1,007.62 in the bank. 



The secretary presented the resignation of Mr. R. Stutz, of Johnsonburg, Pa., 

 which was accepted on motion of Mr. Joutel. 



Mr. Davis, of the field committee, reported that two outings had been arranged, 

 one to Great Notch, N. J., on May 15, and the other to Lakehurst, N. J., May 30, 

 31 and June I. 



On motion of the secretary the society voted to discontinue the meetings during 

 June. 



Mr. Franck read a paper on "The Genus Anthocharis and varieties," and ex- 

 hibited specimens to illustrate. 



He had recently examined about 600 specimens o{ Anthocharis which he had in 

 stock representing nearly all of the species and varieties. On consulting the various 

 authorities he discovered that they all disagreed regarding the variety hyantis. H. 

 Edwards and Strecker treat it as a synonym of cretisa. Smith in his new list retains 

 it as a distinct species. Dyar in his recent list makes it a variety of ausouidis. Skin- 

 ner drops coloradensis as a variety of ausonides and accepts hyanlii as a variety. 

 Mr. Franck agreed with Dr. Skinner on this point. He thought there was but slight 

 excuse for retaining colo> adensis as a separate variety, as a long series shows all inter- 

 grades, and only by selecting extremes can perceptible differences be noticed. 



He also gave some attention to the group containing sara, reakirti, julia and 

 Stella. The type form (summer form) of saia is easily recognized by its larger size 

 and by the underside of the wings being much less olive colored. Reakirti (winter 

 or early spring form) is easily fixed. He finds that the females are not always white 

 as stated in descriptions for he has frequently received yellow females from various 

 localities in California which were captured at the same lime with white males. To 

 julia, accepted as a variety oi sara, yellow females are credited. He pointed out the 

 slight differences between reakirti and jiilia. In examining a lot from Sonoma Co., 

 California, of over 120 specimens he found all males of reakirti {orm, and females 

 both white and yellow, white predominating. One lot from Verdi, Nevada, shows 

 both reakirti and julia males, both white and yellow females. In one lot from 

 Pasadena, California, both julia and reakirti males, all white females. But in one 

 lot from Plumas Co., California, of over 200 specimens, all males both reakirti and 

 julia forms are yellow and all females are yellow.
