FYS CHE. 



[February 1S91. 



Mr. C W- Woodworth recorded the cap- 

 ture in the south-western states of Atracto- 

 cerus braziliensis. The venation is peculiar, 

 bearing a closer resemblance to that of the 

 Meloidae than to that of the clavicorns. 

 The species is distributed from Brazil to 

 Mexico, and this specimen, if taken in the 

 United States, is probably from Texas. 



Mr. S. Henshaw thought the label rather 

 suspicious. He stated that Gorham says in 

 the Biologia Centrali-Americana that the 

 large size of the eyes and readiness with 

 which this insect flies to the light indicate 

 parasitism. 



Mr. Woodworth stated that on pres- 

 sure being applied to Camponotus fensylvan- 

 i'chs a drop of what was apparently water 

 was exuded from the alimentary tract. 



Mr. S. H. Scudder read a paper on the 

 distribution of Anosia plexifpus. 



Dr. H. A. Hagen stated that a species named 

 by him as Libellula vacua was identical with 

 Cordidia lintneri, and has occurred in Mani- 

 toba and the northwest and at Centre, N. Y. 

 He also said that Aeschna grandis which has 

 been taken at Hoboken also occurs in Onta- 

 rio. 



Mr. S. H. Scudder remarked on the analo- 

 gy which the distribution of Cordidia liutne- 

 ri bore to that of Rusticus scudderii, which 

 occurs in Labrador, Manitoba, the Saschat- 

 chawan up to Great Slave Lake, and also at 

 Centre, N. Y. 



11 May, iSSS.— The Club met at 156 Brattle 

 St. Mr Samuel Henshaw was chosen chair- 

 man and Mr. S. H. Scudder, secretary. 



Dr. H. A. Hagen exhibited illustrations 

 and specimens of the early stages of the 

 species of Blepharocera which Fritz Muller 

 has found living in rapid currents in southern 

 Brazil, remarkable for the suckers attached 

 to each segment of the abdomen, by which 

 it is enabled to withstand the rapidity of the 

 stream. Dr. Hagen also gave an account of 

 our knowledge of the history of the several 

 species and in the same connection exhibited 

 the larvae of Blepharocera found by Mr. H 



G. Hubbard in the streams of Michigan. 



Dr. Hagen also announced the discovery 

 of the larva of an unknown species of Sisyra 

 in northern Illinois, and offered some re- 

 marks on the peculiar structure of this larva. 



Mr. C. W. Woodworth mentioned finding 

 a very interesting larva of Stratiomys which 

 used its palpi as locomotory organs. 



Mr. S. H. Scudder called the attention of 

 the Club to the completion of the Rev. Mr. 

 Eaton's monographs of the Ephemeridae, 

 the last part of which had been received 

 within a few days. A discussion ensued, in 

 which accounts were given of the immense 

 numbers of single species of Ephemeridae 

 sometimes seen. 



Mr. Scudder also exhibited a Hemerobius- 

 taken in the house since the last meeting, 

 in which, contrary to what is customary in 

 the Hemerobidae, a cross vein united the 

 subcosta and radius near the tip, though the 

 neuration of the two wings of the spe- 

 cimen did not agree. 



He also read from his forthcoming work 

 on New England butterflies a chapter on the 

 life-history of Anosia plexipp us, with special 

 reference to the annual recolonization of New 

 England from the south. 



Mr. Woodworth gave an account of species 

 of the group Typhlocybidae ; five genera are 

 known in the whole world, all of them found 

 in North America, where we have about 

 thirty species. 



Mr. Holmes Hinkley stated that he had ob- 

 tained an immense number of cut worms 

 from a greenhouse adjoining his residence, 

 where they were now appearing upon the 

 surface every night, attacking the pansies 

 and geraniums, and were supplied to him in 

 large numbers by the proprietor. 



The librarian announced that the Club's 

 library was now stored and arranged on 

 shelves in a room adjoining that in which 

 the meeting was held, where they will be 

 kept for the present, and be accessible to 

 the members on every Tuesday evening as 

 well as at the Club meetings.
