Aids guttata Hulst, Bay of Islands, Nfld., July 21, was the fourth specimen 

 of the species thus far known; the two types came from Pennsylvania and 

 New Jersey, a third specimen was caught at Ottawa. 



Mr. Grossbeck also alluded to the close relation between certain New- 

 foundland and European forms as Noctua baja of Europe and smithii of 

 America which Hampson claims are alike; Pamphiia palamon ; Mesoleuca 

 tncncata approaching closely M. immanata, etc. 



Mr. Leng referring to Mr. Engelhardt's account of the west coast of 

 Newfoundland said that Birchy Cove on Bay of Islands would probably prove 

 better than Humbermouth ; and that the Blomidon Mountains at the entrance 

 to Bay of Islands, reaching an elevation of 2,150 feet, and attainable for col- 

 lecting purposes via York Harbor, as well as St. Anthony on the east coast, 

 should both be investigated before an effective comparison between the fauna 

 of Newfoundland and Labrador could be made. 



Mr. Hall spoke of Distribution of Argynnis (see Short Notes). 



Mr. Grossbeck exhibited a number of caterpillars blown by Mr. Mattis, 

 which were commented upon by Messrs. Davis, Lutz, Southwick and Engel- 

 hardt, especially in reference to the admirable preservation of the natural 

 color. Mr. Engelhardt also described the methods he used. 



Mr. Woodruff recorded an extension of the known range of the Deltoid 

 moth Bomolocha atoiiiaria described from Volga, So. Dak., and found by him 

 at Litchfield, Conn. 



Meeting of March 18. 



A regular meeting of the New York Entomological Society was held 

 March 18, 1913, at 8:15 P. M., in the American Museum of Natural History, 

 President Dr. Raymond C. Osburn in the chair, with 19 members present. 



The curator reported a donation from J. H. Emerton of 80 species of 

 spiders. 



Mr. H. H. Brehme, of Newark, N. J., was nominated for active member- 

 ship by Mr. Grossbeck, seconded by Mr. Davis. 



On motion the by-laws were suspended and the secretary instructed to 

 cast an affirmative balTot, electing Mr. Brehme. 



The president opened the Symposium on Parasitism and Symbiosis in 

 Insects. 



Mr. Comstock, after referring to the general treatment of the subject by 

 Folsom, gave a list of local Rhopalocera» and their recorded hymenopterous 

 and dipterous parasites with numerous additions from his own and Mr. Wat- 

 son's collection. Mr. Comstock described the emergence of various parasites, 

 and spoke of other difficulties in raising larvae, disease, cannibalism, attacks 

 of Hemiptera and other predaceous creatures. Passing to Feniseca tarquinius 

 of which the larva is predatory on woolly plant lice, he said the eggs were laid 

 on alder stems within an inch or two of the groups of lice, the young larva; 

 crawling along the stem to them and, being covered with long hair, soon 

 resembling the lice from the exudations with which they became covered.
