I 890.] ENTOMOLOGICAL NF.WS. 43 



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

 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 organixed under the auspices of the Academy of 

 Natural Sciences, which has recei\ed the co-operation of its individual 

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

 niological Societies. 



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

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

 bounds of the I'nited 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 readied 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 Ca/osonta 

 scrutator? I have always understood that if ever found North of the (in-at 

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

 bark for Allans invops last spring, of which I took nineteen specimens in a 

 few days, 1 found a fresh, living, full-sixed 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. ] : .latcrid(f were peculiarly 

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

 cies of Carabidcc and 21 of water beetles. My prixe is a large green in- 

 sect, apparently a Cantharis, but certainly not one of the common Ca>i- 

 tharidif; also several Ceratnbycidtc and fyrochroidif 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. 1). PKTKKS, JK. 



I b IP W< IKMS. --Late last August I found several larx.e feeding in the 

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

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

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

 ing to be (,'oiiyini nitila (iueii. The \ine from uhich they were taken 

 uas literally riddled with them. No description of the larva- was taken at 

 the time, In it I hope to be able next season to give a more detailed a i count 

 of tlii-rn. Two broods of (.iortyna nilcla, with its variety ;/</>; v'\, were 

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



great rag- weed i A ml in >sia trilida i. This larva feeds also in the stems of 

 burdock (Arctium lappa). As far as my experiem e goes, all the < ', . >i iv na- 

 are internal feeders. C. A. HI.AKK.
