and become single-brooded, or that some closely allied grass- 

 inhabiting Cecidomyid had taken to wheat. 



Mr. Alwood spoke of an outbreak of Goes pulverulcnta 

 on the elm shade trees in the city of Richmond, Va. He 

 described the excessively injurious work of this insect and stated 

 that there had been a loss to the city of from $15,000 to $20,- 

 ooo through its attacks on shade trees. By the cutting down of 

 the badly infested trees and by cutting off the limbs where these 

 only were attacked, at his advice, he considered that the damage 

 had been arrested. 



Dr. Lugger stated that some years ago the allied species Qoes 

 pulchra had been very abundant upon hickories near Balti

Under the head of "Exhibition of Specimens," Mr. Patten 

 showed a live specimen of Lasioderma serricorne taken from 

 a box of Key West cigars. He also showed a cigar from which 

 the beetles had emerged. Mr. Schwarz stated, apropos to this 

 insect, that it does not breed in northern cigar factories and that 

 he doubted whether it would breed in cigar shops in Washington. 

 Mr. Howard gave an instance which had come under his obser 

 vation in which the insects were unquestionably breeding in a 

 small cigar store in Georgetown and stated that the owner had 

 rid his premises by the use of bisulphide of carbon. 



Mr. Ashmead exhibited some interesting specimens from a 

 small collection of Hymenoptera made by Mr. Townsend at San 

 Rafael, Mex. Those to which he called special attention were 

 a species of Amiseon, Trichaulus singularis Mayr, Podagrion 

 toivnsendi n. sp., P. mantis Ashmead (for comparison), two 

 new species of Philanthocephalus and Hontalia earner onii n. sp.
