liibited a large collection of insects made during the past two years among the White Moun- 

 tains, em)>racing many very interesting species, and offered some remarks on their habits. 



Messrs. Cook, Lintner, Morris and Riley were elected members of the (Jlub. 



Mr. Grote presented some instructive facts in relation to the identity of some of the 

 White Mountain moths with those of Labrador. Mr. Riley inquired whether many Calop- 

 teiwi; had been found on Mount Washington, and expressed an opinion that a race of spreili.i 

 had been found there. 



Mr. Saunders inquired of the Michigan Iriends whether rirris nqnv had been found in 

 the State. Prof. Conk stated that it had not yet appeared in Michigan ; he remarked that 

 protodire was much more numerous than olcracea. Mr. Riley stated that jn-ofodice was most 

 abundant throughout iUiuois and Missouri. Mr. Ison, of Cleveland, stated that ?-w;)(r' ap- 

 peared in his neighbourhood for the first time last spring ; at first it was found aluug the lake 

 shore, but before the reason closed it was abundant throughout the greater part of the district ' 

 over which his observation had extended. Mr. Ison said that with them the larva seemed to 

 prefer mignonette to cabbage. In reply to a question as to the correctness of the views ad- 

 vanced by some Entomologists in regard to the colour of the imago being afiectcd by this 

 food plant, Mr Lintuer said that he had, from among 500 or 600 specimens fed on cabbage, 

 found a number of the yellow variety. Mr. Riley stated that the larva of prokidice was also 

 partial to mignonette. 



Danais o.rckippus formed the next topic of discussion. Mr. Cook had found the larva 

 this season peculiarly infested by several parasites. Mr. Riley had seen Tachina flies bred 

 from nrclnpjms. Mr. Saunders had reared, on one occasion, a large number of small Hymenop- 

 terous parasites from a chrysalis. He also a.-ked the members if any explanation could be given 

 of the rea.son why this species assembled occasionally in immense swarms and migrated thus 

 from place to place, and referred to instances of such swarming. Mr. Json referred to an im 

 mense swarm which passed over Cleveland three years ago. In this instance it appeared as if 

 they had crcssed the lake from Canada ; they were seen in immense numbers for three or four 

 days. Archiiqms was said to occur in Australia, where it al.so occa.sioiially swarms. 



References were made by Mr. Grote to several rare captures of Lepidoptera in the vicinity 

 of Buffalo. Among others he had taken Theda oce/lifcra, which is al.so found in the West 

 Indies. Mr. Saunders stated that he had again reared a specimen of Theda driqosa from 

 Ihorn, and referred to the capture of specimens of P. thnar; and P. marcellus at North Ridae, 

 Ont., by Mr. F. C. Lowe, of Dunnville. Mr. Cook said that thoas had been found this year 

 at Lansing, that it occurred there to his knowledge some three years ago, and that last season 

 it was quite common, the larva feeding on prickly ash. Mr. Riley stated that the larvae of 

 phi/enor feed on a creeping plant very closely allied to Aristolochia. Mr. Ison has found 

 phiknar scarce about Cleveland during the last five or six years, but mura'Uus rather com- 

 mon ; the larva of the latter feeds on pawpaw. One of the Detroit members remarked that 

 there were jiawpaw liushes growing within a few miles of Detroit. 



A discu.ssion on .sugaring for Noctuse was next in order. Mr. Ison reported excellent 

 success with this method at Cleveland ; he pieferred adding a little rum to the usual mixture 

 of beer and molasses or coar.se sugar. Mr. Lintner greatly interested the members in relating 

 hie wonderful success in sugaring. He produced a tabulated list of Noctuidae captured or ob- 

 served at sugar at Schenectady, N. Y., commencing with July 7th, giving the results of six- 

 teen evenings in that mouth, and four evenings in August. 



Seventy-eight species of Noctuae are recorded, and opposite each species observed or col- 

 lected is ])laced a check in a colunm bearing the day of the month at its head. Four species 

 were observed on each evening, viz. : — //(((/«»« arrtica, JJijdroecia sera, Homnpi/ralis larttis 

 and Asojiia costalis. Cf the first two, hundreds could have been collected on a single evcnins. 

 IJudeiia Ugnicolor was unobserved on only one evening ; Erastria carneola on only two 

 evenings; Calorala iiltnmia and lliidcna devastator on only three evenings. 



The following s])ecies were common : — A. liarbkhi, A. haru.<!pica, A. plecta, Orthodes in- 

 finna, J'sem/othi/atira cxpullrix, IJi/driieda nictituris, Amphi/ii/ra jii/ramidoide.i and Enistria 

 iiujritula. Of Vatocala uUroiiia about seventi/ examples in fine condition were captured ; of 

 Catocahi niiptala, of which not a .single example h.id ever before been taken by .Mr. ]j., thirty- 

 six were collected ; and of Cntooda par/a sixteen examples had been secured, all in perfect 

 Condition. Specimens of Caloada Mcskei, C. Serena, C. Briseis, G. Clmtonii, C. polygona 

 and (J. siinlli.s had -lUo been obtained.
