I89O.] ENTOMOLOGICAL NEWS. 45 



A large part of the region to be traversed will lie away from civilization, 

 necessitating travel by primitive methods, and for some distance probably 

 the protection of an armed escort will be necessary, especially in the re- 

 gion of the revolted Indian tribes of Yucatan. 



The expedition is organized under the auspices of the Academy of 

 Natural Sciences, which has received the co-operation of its individual 

 members, and also of the American Philosophical and American Ento- 

 mological Societies. 



This expedition, it is stated, is the first extensive one that has been or- 

 ganized by a scientific institution in this country' to be sent outside of the 

 bounds of the United States for many years, and its results are awaited 

 with a great deal of interest by scientists. 



The entomological collections, which will be made in all orders, will be 

 distributed among the leading specialists, and the conclusions reached by 

 them will be published in the Proceedings of the Academy of Natural 

 Sciences of Philadelphia, or in the Transactions of the American Ento- 

 mological Society. The narrative of the expedition will probably be pub- 

 lished in separate book form. 



Editor Entomological News : — I should like to ask some of your 

 readers if Sudbury, Ontario, is not a very Northern locality for Calosoma 

 scrutator? I have always understood that if ever found North of the Great 

 Lakes it came only as a shipwrecked mariner. While looking under pine 

 bark for Alans niyops last spring, of which I took nineteen specimens in a 

 few days, I found a fresh, living, fiill-sized specimen of C. scrutator. 



Altogether, I took some 450 different species of beetles here last season, 

 but cannot get more than half of them named. Elateridce were peculiarly 

 plentiful. I took some 200 individuals and nearly 30 species; also 42 spe- 

 cies of Carabidcs and 21 of water beetles. My prize is a large green in- 

 sect, apparently a Cantharis, but certainly not one of the common Cati- 

 tharidce; also several Cerambycidce and Pyrochroidce that local entomolo- 

 gists cannot determine. 



Lepidopterists will be interested to know that Colias interior, both male 

 and female, are quite common here in the season. — E. D. Peters, Jr. 



Hop Worms. — Late last August I found several larvae feeding in the 

 Hop (Humulus lupulus). I removed portions of the stems, cutting five 

 or six mches above and below the swellings, and placed them in a box 

 used for feeding larvae. In about three weeks the imagos emerged, prov- 

 ing to be Gortyna rutila Gu^n. The vine from which they were taken 

 was literally riddled with them. No description of the larvae was taken at 

 the time, but I hope to be able next season to give a more detailed account 

 of them. Two broods of Gortyna nitela, with its variety nebris, were 

 raised in the same manner. The larvae were feeding in the stems of the 

 great rag-weed (Ambrosia trifida). This larva feeds also in the stems of 

 burdock (Arctium lappa). As far as my experience goes, all the Gortynae 

 are internal feeders. — C. A. Blake.
