Mr. Comstock said Cyaniris ladon was surely its specific name, but the 

 standing of the names marginata, lucia, violacea, for its seasonal forms was 

 still in dispute ; some collectors holding that each of these represents a dis- 

 tinct succession of Spring forms appearing about ten days apart, others that 

 marginata and lucia cannot be separated, others that violacea also is insepar- 

 ably connected by intergrades ; all however agree in calling the summer brood 

 in which the spots are almost obsolete, neglecta. Mr. Comstock said that the 

 spring larvse feed on the developing flower buds of benzoin, wild cherry, 

 viburnum, etc., and are difficult to raise, though W. H. Edwards had suc- 

 ceeded in doing so. The summer form, neglecta, feeds on Ceanothus. He 

 added that the number of broods probably varied in different seasons, the 

 allied species comyntas having certainly four broods in some seasons. Further 

 south the succession of spring forms differs from that observed near New 

 York, and pseudargiolns becomes a predominant form at certain seasons. 



Mr. Davis spoke of the similar difference observed in spring form of 

 luna moth. 



Mr. Leng exhibited specimens of Arthromacra ccnea and a different spe- 

 cies of the same genus collected by Col. Wirt Robinson, in Nelson Co., Va., 

 and communicated by him in which a bright green color was accompanied by 

 difference in pronotal punctuation, and relative length of antennal joints, as 

 pointed out by Col. Robinson, who also noticed that there was no commingl- 

 ing of the two forms in copulation. 



Mr. Davis exhibited photographs of Philadelphia Academy of Sciences, 

 and spoke of his kindly reception at a recent meeting of the entomological 

 section and at a meeting of the Feltman Collecting Social, which he had 

 also attended, expressing his admiration for the great work being accom- 

 plished in that city by a comparatively small number of men. He said this 

 was doubtless aided by the magnificent library and the facilities for its use, 

 each member being provided with a key so that he can work undisturbed 

 at evening. 



Mr. Angell spoke of the metallic colors in Coptolahrns, and the crimson 

 hue that was caused by water being applied to the elytral surface, as he dis- 

 covered in relaxing and remounting, affording another illustration of the 

 mechanical character of the colors. 



Meeting of March 17. 



A regular meeting of the New York Entomological Society was held 

 March 17, 1914, at 8:15 P. M., in the American Museum of Natural History, 

 Mr. G. W. J. Angell in the chair and seventeen members present. 



Mr. Davis under the title " Remarks on Some Orthoptera from the East 

 Coast of Florida " showed his extensive collection of Floridian Orthoptera 

 and a large number of photographs thrown on the screen by radiopticon. Mr. 

 Davis said that 92 species were taken by Mr. Sleight and himself on their 

 recent visit to the East Coast, and 104 species had been taken on his several
