To North American Entomologists. 



The undersigned beg leave to present the following statement :— 



Psyche, published by the Cambridge Entomological Club, has 

 met with such a favorable reception on all sides, that its contin- 

 uance in its present form is assured, but it is found impossible 

 within the limits of four pages each month to bring up to date* 

 the Bibliographical Record of North American Entomol- 

 ogy, indispensable to every entomologist. The members ol the 

 Club have therefore decided to double the numbers for January 

 and February, and to make this enlargement permanent, if sulli- 

 cient support is guaranteed before the first of March, L875. To 

 accomplish this, at least eighty new subscribers are needed. 



Psyche will contain such parts of the proceedings of the Cam- 

 bridge Entomological Club as are of general interest, contribu- 

 tions upon the habits of insects, lists of captures, and a record of 

 all writings upon entomology published in North America, and of 

 all foreign writings upon North American insects since the be- 

 ginning of 1874, with a brief note on the contents of each. 



The members also call the attention of collectors of insects to 

 the value of Psychk as a medium for exchange, as lists of dupli- 

 cates will be inserted at moderate rates. 



The terms of Psyche are one dollar a year, in advance. No. 1 

 was issued May, 1874; but subscriptions may begin at any date. 

 A specimen number will be sent on application. Address.;
