Mr. Osburn and Mr. Sleight reported the receipt of a number of photo- 

 graphs to add to the collection. 



Mr. Engelhardt presented the name of Mr. Rowland R. McElvare, 231 

 Decatur St., Brooklyn, as an active member. On motion, the by-laws were 

 suspended and the secretary instructed to cast a single ballot for the election 

 of Mr. McElvare. 



Mr. Hallinan, through Mr. Davis, presented two interesting letters to add 

 to the collection of letters of eminent entomologists, one from A. S. Packard, 

 dated October 23, 1871, and the other from Samuel Lockburn, dated May 25, 

 1869. 



Mr. Engelhardt related his travelling experiences in a short trip to the 

 Adirondack Mountains in September, when he visited Ausable Chasm, Keene 

 Valley, Cascade Lakes and Lake Placid. Among others the following insects 

 were shown : Lepidoptera — Catocala relicta, Fylina baileyi, petulca, disposita, 

 unimoda, georgii, Litholomia napal, Lithomoia germana, Polia sp., Hyphoraia 

 partJienos cocoon, Notolophtis antigua, Dryobota jjlocato ; Coleoptera — Dytiscus 

 harrisii, Ilydrobius globosus, Cicindela rcpanda, var. 12— guttata, Dicerca pro- 

 longata, Adelocera brevicornis, Meloe angusticollis, the last named abundant at 

 Cascade Lakes ; Orthoptera — Pezatettix glacialis, on hazel nut at Lake Placid ; 

 Hymenoptera — Bombus ternarius, perplexus, fervidns, terricola and an undeter- 

 mined species ; Diptera — Spilomyia quadrifasciata, fusca and Conops sp. 



Mr. Olsen read an account of some experiments he had made in rearing 

 Corniopepla carnifex in order to determine the life history. As the eggs were 

 sucked dry by the young bugs, he had found it necessary to isolate these as 

 soon as hatched. 



Mr. Leng read a paper on " Variable Maculation in Coccinellidse." He 

 commented on the great range of maculation and tendency to variation in the 

 members of this family and referred to some recent papers by Roswell Johnson 

 and Major Casey in which are described a number of new species founded on 

 slight differences of maculation and which in his opinion should not in many 

 cases be given varietal rank as it is possible to find in a large series intergrading 

 forms. Mr. Leng's entire paper is printed in the body of the Journal. 



In this connection Dr. Lutz exhibited specimens of the common asparagus 

 beetle showing three different color variations which had been given varietal 

 names by European Coleopterists. When interbreeding these varieties Dr. Lutz 

 found that they held constant. 



Mr. Engelhardt exhibited a number of Cleis picta from Claremont, N. H., 

 to show the degree of variation in this species of Coccinellidse. Mr. Dickerson 

 referred to the range of variation in the Coccinellid, Hyperaspis signata, which 

 feeds on the cottony cushion scale of the maple, in which certain specimens 

 had an extra apical spot on the elytra, Mr. Davis exhibited a number of the 

 local species of Coccinellidae, showing variation in the typical maculation, 

 which in some cases was due to injury in the early stages, in others the right 

 and left elytra were unlike. Mr. Hyde exhibited some cocoons of spiders 

 illustrating an excellent method of preparing these for exhibitions. 



Mr. Schaeffer exhibited specimens of butterflies of Papilio dardanus subsp.
