Germantown. Mr. Hornig had found the larvae at Washing- 

 ton Park, Catnden Co., N. J. Mr. Laurent suggested that 

 the species may winter as egg as well as larva. D. Skinner 

 exhibited some Coleopterous larvae, sent to him by Mr. Edward 

 Potts. They have the peculiar habit of crawling quite rapidly 

 on their backs. They were identified by Prof. Smith as Allo- 

 rhina nitida. Mr. C. W. Johnson exhibited some flies he had 

 found on the decayed berries of a vine at the grounds of the 

 Biological School of the University of Pennsylvania. He also 

 found one on decayed grapes at Riverton, N. J. Mr. Coquillette 

 determined it to be Chrysomyza demandata Fabr. , a European 

 species. Mr. Johnson did not know of any previous record for 

 American specimens. Dr. Calvert gave an account of the 

 classification of some of the Odonata.

The ninth regular meeting of the Harris Club was held at 

 35 Court St., Boston, on Friday evening, September 21, 1900. 

 Mr. W. L. W. Field gave a brief talk on the quantitative study 

 of variation in insects. Mr. A. P. Hall exhibited a specimen 

 of the occasional red suffused form of Attacus cecropia, and also 

 a specimen of Adias Inn a, whose wings bore fast-fading shadowy 

 transverse lines, similar to the lines upon the wings of A. 

 sclcne. A photograph taken when the specimen was fresh 

 showed that the lines had been much more distinct at that 

 time. A like specimen, taken in Guilford, Conn., in 1894, by 

 Mr. Field, has altogether lost the transverse lines in the space 

 of six years, and now has the aspect of a perfectly normal Inna. 



Mr. Field reported the existence of what appears to be a 

 thriving colony of Enodia portlandia in the Cold River Valley 

 of southwestern New Hampshire. This butterfly is rare in 

 most parts of New England. 



Mr. Newcomb brought forward several exhibits, comprising 

 a series of Chrysophanns hypophlu-as showing .variation through 

 a wide range of patterns ; an albino Phyciodcs tliaros, in which 

 the ground color is white instead of tawny ; a deep gray female 

 of Lcncarctia itcr<rti, resembling the aberrant male form of the 

 same species quoted by Harris ; and lastly some cocoons,
