THE IMITATIVE FACULTY OF CATOCALA COXCUMBENS. A few years 

 ago, while collecting butterflies on a road near Manchester, N. H., I 

 noticed a fine specimen of Catocala concumbens resting on a telegraph- 

 pole. On inspecting the pole more closely I found four more specimens 

 of the same species. I examined the tree-trunks and fence-rails in the 

 neighborhood, but failed to find others, but on almost every telegraph- 

 pole for a quarter of a mile I found from one to ten of these common 

 moths. Every year since that time I have taken this species on these 

 same poles, but none could be found on the neighboring tree-trunks. 

 This year a lot of new telephone-posts were put up beside the old poles, 

 but never have I found an insect on the new posts. May it not be that 

 this moth, accustomed by natural selection to find its mate of this pecu- 

 liar gray color, chooses a post of a similar color on which to alight? This 

 would be a possible explanation of the selection of these particular poles 

 for a resting place. EDWARD WINSLOW CROSS. 



Identification of Insects (Imagos) for Subscribers. 



Specimens will be named under the following conditions : ist, The number of species 

 to be limited to twenty-five for each sending ; 2d, The sender to pay all expenses of trans- 

 portation and the insects to become the property of the American Entomological Society ; 

 3d, Each specimen must have a number attached so that the identification may be an- 

 nounced accordingly. Exotic species named only by special arrangement with the Editor, 

 who should be consulted before specimens are sent. Send a 2 cent stamp with all insects 

 for return of names. Please put date of capture and exact locality on each specimen. 

 Before sending insects for identification, read page 41, Vol. III. Address all packages 

 to ENTOMOLOGICAL NEWS, Academy Natural Sciences, Logan Square, Philadelphia, Pa. 



Entomological Literature. 



Under the above head it is intended to note such papers received at the Academy of 

 Natural Sciences of Philadelphia pertaining to the Entomology of the Americas (North 

 and South). Articles irrelevant to American entomology, unless monographs, or con 

 taining descriptions of new genera, will not be noted. Contributions to the anatomy of 

 insects, however, whether relating to American or exotic species will be recorded. 



(The Associate Editor, in re-assuming charge of the preparation of these monthly 

 summaries of Entomological Literature, desires to express not only his own thanks, but 

 also, he believes, those of the readers of the NEWS, to Mr. William J. Fox. who has so 

 acceptably performed this task for the journal from June, 1895, until Oct., 1896. P. P. C.).
