PROCEEDINGS OF THE SOCIETY. 



Meeting of January 13, 192 1. — The same officers of the So- 

 ciety were reelected to serve during the year 192 1. 



Scientific Programme. — Mr. Jacob Doll communicated '' Notes 

 on Some Interesting Lepidoptera." Referring to Mr. Engel- 

 hardt's remarks at the preceding meeting on Utetheisa hella, he 

 exhibited a large series of color variations of this species selected 

 from some 30,000 to 50,000 specimens which have passed through 

 his hands in the last 50 years. The caterpillar of this moth lives 

 on the rattle box (Crotalaria) . From his breeding experience, 

 Mr. Doll found that one year a lot of larvae that had been starved 

 gave a great variety of color forms, while adults from another lot 

 that had been well fed, were almost all alike. The wide range of 

 variation is exhibited by only the females in this species, while 

 the males are all very similar. Mr. J. R. de la Torre Bueno read ■ 

 a paper on the " Saldidae of New York State." Mr. Howard 

 Notman exhibited a series o.f the moth Eufidonia notataria Walker 

 from Keene Valley, Adirondacks, N. Y., including many color 

 variations. 



Meeting of February 10, 1921. — Scientific Programme. — "Ex- 

 hibition and Discussion of Interesting Insects." Mr. Howard 

 Notman showed Cinclidia harrisi Scudder collected by him in a 

 little meadow at the top of a hill at Keene Valley, Adirondacks, 

 N. Y., one of the specimens representing quite a distinct color 

 form. Mr. Wm. T. Davis mentioned having taken the same moth 

 at Hewett, N. ]., June 19, and at Potter Swamp, Yates Co., N. Y., 

 June 14, 1915. Mr. Chas. Schaeffer spoke of a specimen of 

 Trogus fulvipes Cresson received from Mr. Doll, who obtained it 

 from a pupa of Papilio turnus. Since there are no structural dif- 

 ferences between T. fulvipes and the common T. vulpinus (Gra- 

 venhorst), there is a question whether the former is specifically 

 distinct. Dr. J. Bequaert gave a brief account of his collecting 

 experiences with Mr. Notman in the Adirondacks last summer. 

 Mr. Davis exhibited several interesting Diptera : Hermetia illucens 

 (Linnaeus), taken at Arlington, Staten Island, N. Y. ; Mydas 

 clavatus Drury, also from Staten Island, usually found flying
