say whether his collection, now owned by 

 Oberthiir, contains any specimen from either 

 country; but he possesses specimens from 

 French Guiana collected by Constant Bar at 

 Isle Portal on the Maroni, the river which 

 separates French and Dutch Guiana. He 

 gives a list of other localities from which he 

 possesses specimens, but none of them are of 

 special importance. 



PROCEEDINGS OF SOCIETIES. 



CAMBRIDGE ENTOMOLOGICAL CLUB. 



8 March 1S89. — The 144th meeting was 

 held at 156 Brattle St., the president in the 

 chair. 



Dr. H. A. Hagen said that the cyclamens in 

 a greenhouse in Montvale, Mass., had been in- 

 jured by Otiorhynchus sulcatus , and remarked 

 on the history of our knowledge of its depre- 

 dations in America. 



Mr. S. Henshaw stated that it had recently 

 heen introduced into New Zealand where it 

 is also doing much damage. 



Mr. H. Hinkley showed a variety of Satur- 

 tiia io in which the eye-spot on the hind wing 

 is almond-shaped. He has raised a large 

 number and showed a fairly large series 

 which exhibited some very prettv gradations 

 of color. 



Mr. S. H. Scudder remarked on the former 

 range of distribution of Pieris oleracea. He 

 gave as a reason why P. rafae has extermi- 

 nated P. oleracea that the first brood of the 

 former hatches about two weeks earlier than 

 that of the latter species. 



Mr. Scudder then read a paper on cosmo- 

 politan butterflies. 



Dr. H. A. Hagen remarked briefly on the 

 distribution of certain dragon-flies in Brazil, 

 showing that many are extremely local. 



Mr. J. H Emerton showed drawings of the 

 copulatory organs of Agalena naevia. The 

 palpal organs are, with few exceptions, of 

 three varieties, the most common variety 

 having a stout spiral tube of one and a half 



turns with the tip turned outward. Another 

 variety found only in large individuals has 

 the tube longer and more slender, and a third 

 variety found in spiders of various 6izes, has 

 the tube very short and coiled in a small 

 spiral. The epigynum is of two principal 

 forms; one with a simple opening, and the 

 other, usually occurring in large spiders> 

 with a wide opening partly divided into two 

 by a process from the front edge ; between 

 these are many intermediate forms. The 

 other parts of the male palpi vary but little 

 and there are no other variations which 

 would show that we have more than one 

 species of these spiders. 



Mr. Emerton stated that he had found a 

 new species of spider in the natural history 

 society building in Boston. There were two 

 specimens, one male and one female. They 

 may be foreign as they were found near some 

 West Indian material that had been there for 

 about two years. 



[The records of several meetings at this 

 point have been lost.] 



11 October, 18S9. — The 148th meeting of 

 the Club was held at 156 Brattle St., the 

 president in the chair. 



The secretary stated that the records of the 

 last meeting had been mislaid. 



Mr. S. H. Scudder gave an account of what 

 had been done at the meeting of the Execu- 

 tive Committee, and showed the circular 

 which was sent soliciting subscriptions to 

 Psyche. 



Mr. Scudder then gave a brief account of 

 his field work in the west during the past 

 summer for the U. S. Geological Survey. 

 Having first visited Florissant in order to 

 make sure of bringing home a sufficient 

 number of fossil insects to warrant the out- 

 lay of the expedition, he next went to west- 

 ern Colorado to examine two localities near 

 together. One of them on the summit of the 

 Roan Mountains, on the divide between the 

 White and Grand Rivers, where fossil plants 

 of species identical with those found at Flor- 

 issant had been obtained many years ago,
