OF THE GLOBE. 



[The Conductors of Entomological News solicit, and will thankfully receive items

To Contributors.— All contributions will be considered and passed upon at our 

 earliest convenience, and as far as may he, will be published according to date of recep- 

 tion. Entomological Nkws has reached a circulation, both in numbers and circumfer- 

 ence, as to make it necessary to put " copy'" into the hands of the printer, for each number, 

 three weeks before date of issue. This should be remembered in sending special oi im- 

 portant matter for certain issue. Owing to low subscription rate. " extras" will be charged 

 for, and when they are wanted, it should be so stated on the MS. along with the number 

 desired. The receipt of all papers will be acknowledged. — Ed. 



Pictures for the Album of the American Entomological So- 

 ciety have been received from H. F. Bassett, C. H. T. Townsend, Philip 

 Laurent, H. F. Wicicham. There are many more we want who have not

Prof. Lawrence Bruner, of the University of Nebraska, is writing a 

 revision of the "Grouse Locusts" (Tettiginae). In order to make the 

 work as complete as possible, he will be pleased to receive sets of these

To those already, or about to be, interested in the Odonata, or Dragon- 

 flies, it may be of interest to announce that the writer's catalogue of the 

 Odonata of the vicinity of Philadelphia is expected to appear in the 

 " Transactions" of the American Entomological Society about the close

2. A catalogue of the species found near Philadelphia and of other N. 

 American species for comparison, with.brief characters and descriptions; 



3. A comparison of the Philadelphia Odonat fauna with that of North 

 America, etc. The general description will serve as an introduction to 

 the study of this group and will be more detailed than any account pre-

 entomologists who are not concerned with the Philadelphia fauna. Illus- 

 trations will accompany the text. — P. P. C.

 two segments, protocerebron and deutocerebron, both entirely pre-ceso-
