ENTOMOLOGICAL NEWS. 



Published monthly (except July and August), in charge of the joint 

 •publication committees of the Entomological Section of the Academy 

 of Natural Sciences, of Philadelphia, and the American Entomological 

 Society. It will contain not less than 300 pages per annum. It will main- 

 tain no free list whatever, but will leave no measure untried to make it a 

 necessity to every student of insect life, so that its very moderate annual 

 •subscription may be considered well spent. 



ANNUAL SUBSCRIPTION $1.00, IN ADYANCE. 



Bi^° All remittances should be addressed to E. T. Cresson, Treasurer, 

 P. O. Box 248, Philadelphia, Pa.; all other communications to the Editors

TYPE SPECIMENS. 



We have received a letter from Prof. T. D. A. Cockerell which ex- 

 presses our views exactly in regard to type specimens, and we think it so 

 important that we reproduce it here. The majority of types are not 

 unique, and at least one could be spared for some public collection : 



" I want, so far as possible, to make a practise of always sending you 

 type specimens along with the descriptions, and I think it would be a re- 

 markably good thing if no descriptions were allowed to stand unless the 

 types were deposited in a public collection. In the term ' public collec- 

 tion' I should include such as that of the American Entomological Society, 

 which I understand can always be seen by respectable entomologists. 



" I do not think for a moment that we really could refuse to recognize 

 descriptions not thus represented by types; but we might at least make 

 the practise of placing types in accessible collections a common one, so 

 that public opinion would condemn those who failed to do so. In certain 

 instances it seems justifiable to retain types during one's life-time. Thus, 

 Lord Walsingham is keeping his types of Tineidse, which he no doubt 

 finds necessary for his work; but he has arranged that upon his death they 

 shall go to the British Museum. Such a collector as Dr. Holland ought 

 certainly to do the same; possibly he has done so. If on his death his 

 numerous types were distributed by sale it would be a great pity, and I 

 might add, a serious injustice to other lepidopterists all over the v/orld." 



Pictures for the alburn of the American Entomological Society have 

 Ijeen received from Prof. D. S. Kellicott, Dr. R. E. Kunze, C. V. Piper, 

 A. G. Weeks, Jr., M. J. Elrod. We have not received nearly all that we 

 would like. We want pictures of all the entomologists of the world.
