worth, of Cambridge, for active membership^

 and G : Dimmock. 



The chair appointed Messrs. S: H. Scud- 

 der, J. II: Emerton, R. Hayward, C:W: 

 Woodworth and G : Dimmock a committee 

 to consider the feasibility of publishing 

 Psyche. 



Mr. C : W : Woodworth remarked on two 

 larvae he had observed. 



Mr. R. Hayward showed a specimen of 

 Erebus odora from Lower California. 



Mr. Dimmock spoke of a cocoon of a lepi- 

 dopterous larva he had observed, which was 

 made entirely of human hair. 



9 December 1887. — The 133rd meeting was 

 held at 61 Sacramento St., Cambridge. The 

 president, Mr. J. H: Emerton, in the chair. 



The report of the committee appointed at 

 the last meeting to consider the feasibility of 

 continuing the publication of Psyche was 

 presented by Mr. S: H. Scudder, chairman of 

 the committee. The report was accepted and 

 in accordance with the recommendations of 

 the committee it was voted to begin a new 

 volume with 1888. 



Mr. S : H. Scudder read a letter from Miss 

 Adele M. Fielde, and exhibited, among other 

 specimens sent him by that lady from China, 

 two specimens of a grasshopper ( Conoccphalus 

 acuminatus) , the chirp of which, as Miss Fielde 

 aptly expi-esses it, "makes the heat audible." 



Mr. Scudder showed some larvae and pupae 

 oi Pier is rapaewh'xch. he has kept in a half 

 and half mixture of glycerine and watei- since 

 1871. They still retained their color. 



Mr. Holmes Hinkley showed soine speci- 

 mens of spiders which he had taken from the 

 cells of a mud-wasp. 



Mr. J. H : Emerton showed a specimen of 

 Lycosa kochii which makes a noise by drum- 

 ming on the leaves. The species lives 

 amongst dead leaves in the woods and the 

 drumming is supposed to be done with the 

 palpi. The specimen in question was from 

 Staten Island and was collected by Mr. W. 

 T. Davis who would publish his observations 



in the Proc. Nat. hist, assoc. of Staten Island 

 Mr. Emerton said that he did not know of the 

 occurrence of this spider in this vicinit}'. 



Mr. J. W. Folsom stated that he had 

 observed this spider near Arlington. 



Mr. G : Dimmock showed a Swiss spider 

 which had bitten him, causing considerable 

 poisoning. 



Mr. Emerton identified it as a species of 

 Ti'genaria. Mr. Emerton then examined the 

 spiders shown by Mr. Hinkley and found 

 amongst them several species, the majority 

 being young Epeira. He remarked that 

 spiders stored in the nests of niud-wasps re- 

 main pliable for some time. 



Mr. C : W : Woodworth remarked that he 

 had known instances where one of the spiders 

 had recovered and devoured the rest. 



Mr. Hinkley stated that he had examined 

 the larvae of some .<^;«('/'/«^^/ and observed the 

 ichneumon larva feeding under the skin, and 

 in a few hours the pupa was found on the 

 outside. He then asked how this was 

 brought about. 



In answer to the inquiry, Mr. S : H. Scud- 

 der stated that the larva emerges and forms 

 its cocoon on the outside in a very short time. 



Mr. Woodworth asked what effect the warm 

 weather would have upon insect life. 



Mr. S: Henshaw showed a piece of bed 

 ticking with a felling produced by Attagemis 

 megatoma. The larva gnaws the feathers, 

 forming a fine dust, and the felting is stated 

 by Prof. C : V. Riley to be due to the mere 

 mechanical process of beating and shaking.
