THE CAMBRIDGE ENTOMOLOGICAL CLUB 



Respectfully solicits Iron] entomologists and the general public 

 pecuniary assistance needed to defray the expenses of its gratu- 

 itous labors for the promotion of North American Entomology. 



This Club, having its headquarters in Cambridge, Massachusetts, i > u t 

 its membership distributed from Maine to ( Jaliforuia, has published, during 

 nearly three years, a monthly periodical entitled Psyche. This magazine 

 has contained, besides the das-; of matter usually found in an entomolog- 

 ical publication, a current Bibliographical Record <>i' all writings upon 

 Entomology published in North America, and of all foreign writings upon 

 North American Entomology, from the beginning of the year L874. It is 

 upon the value of this Record thai the Club bases its claim for assistance 

 from all persons disposed to render aid. [ndeed. the magazine was start- 

 ed principally as a channel for the publication of this Record, which has 

 occupied aboul 80 out of the 176 pages already issued. 



Past experience shows that an annual income of nearly one hundred 



and fifty dollars re than can be expected from ordinary subscriptions is 



needed to save the Club from exceeding its resources in the publication 

 of this magazine, It has therefore beeii determined to establish a publi- 

 cation fund of at least two thousand dollars, the income of which is to be 

 devoted solely to the publication of this magazine with itsRecord. Should 

 this fund be secured, American Entomologists will have the satisfaction 

 of possessing a em-rent analysis of the literature of their own department 

 nmn carefully prepared and mou promptly issued than any which the students 

 of other departments possess. At the end of each volume of Psyche a classi- 

 fied index to the Record will be given; this index, in itself, will consti- 

 tute a treatise upon entomology more instructive and comprehensive, in a 

 small space, than is obtainable elsewhere. 



All persons who are disposed to contribute to this fund may rest 

 assured that while the largest genei^osity will be fully appreciated, any 

 small sum will be gratefully received, and all the means placed at the 

 disposal of the Club will be used in the most impartial manner for the 

 benefit of North American entomologists, without regard to further terri- 

 torial distinctions. 



Contributions may be sent to B. Pickman Mann, Cam- 

 bridge, .Mas,-,. ; acknowledgements will be made by letter, and 

 will be published on the cover of Psyche. 



Mr. C. V. Riley writes, iu contributing live dollars to the publication 

 fund of Psyche: ••! will be one of si hundred to contribute twenty-five 

 dollars, and whenever you secure the other ninety-nine, call on me for 

 the additional twenty dollars. There ought to he a hundred entomologists 

 in the country, willing to thus establish your little Bui lei in. which, if not 

 run in the interest of any local faction, may become invaluable.*' 



four persons have promised already to contribute on these conditions.
