OF WASHINGTON. 439 



bees have become somewhat yellow on the abdomen, whereas 

 the pure strain is gray. This fact is attributed by the natives 

 to cross breeding of the bees with the drone fly, Eristalis 

 ten ax. 



APRIL 12, 1900. 



The i5ist regular meeting was held at the residence of Dr. L. 

 O. Howard, 1336 3oth street. President Dr. Gill in the chair, 

 and Messrs. Mathis, Chapin, Kotinsky, Busck, Dyar, Morris, Pol 

 lard, Ashmead, Vaughan, Howard, Heidemann, Marlatt, and 

 Hay, active members, and Professor B. W. Evermann, visitor, 

 also present. 



The Corresponding Seen tary announced the death of Mr. 

 A. Bolter, of Chicago, 111., Corresponding member of the Society, 

 which took place on March 18, 1900. 



Under the head of Short Notes and Exhibition of Specimens, 

 Messrs. Morris, Chapin, Ashmead, Dyar, and Mathis discussed, 

 briefly, the crippling or non-expanding of wings of Attacus poly- 

 phcmus in a dry atmosphere or in a confined space. 



Mr. Heidemann showed a new species of the Tingitid genus 

 Proxius, collected by Messrs. Hubbard and Schwarz at Tampa, 

 Fla. This is the first specimen of this genus found in the United 

 States. It is probably identical with one of the forms described 

 by Champion from Central America. Mr. Ashmead said that he 

 had taken several Mexican beetles on Metacumbe Key, Fla., and 

 Dr. Dyar remarked that the insect fauna of the east coast of south 

 ern Florida is West Indian, and that of the west coast is more 

 Mexican. 



Mr. Busck showed a handsome Tineine collected in Florida 

 by Dr. Dyar, the larva of which constructs a y-chambered case on 

 palmetto leaves. He proposed to erect a new genus for this form 

 and will call it Homaledra. It belongs to the Elachistidse. 



Dr. Dyar spoke of the curious change in the color of the head 

 of the larva of a Syntomid in which the head is colorless until the 

 7th stage, when a strong U-shaped black mark appears, which, 

 however, is again lost in the final stage. This instance is unique 

 in his experience.
