parents. He pointod out that some specimens had entirely lost the clear space in 

 both sets of wings, which made them look quite distinct. There was no variation in 

 the larva; or in the conditions in which they were bred. 



Mr. Barber said that he wished to put on record what seemed to him a ver)- 

 peculiar breeding place for a bot-fly. Mr. E. H. Emerton had noticed one day at 

 Cold Spring Harbor, Long Island, a common box turtle that had a peculiar swelling 

 under the edge of the shell near the head. They discovered that the swelling was 

 ojien in front and within, by means of forceps, they found several grubs of a bot-fly. 

 These were removed and placed in a proper jar for maturing. In a recent communi- 

 cation Mr. Emerton stated that he had obtained the fly and had determined it as a 

 species of the genus Suj-iop/iaga. Mr. Beutcnmiiller and Mr. IJrues both stated that 

 they had seen a record of the occurrence of the bot-fly on the turtle. 



Mr. Schaeff"er spoke concerning some of the genera of Cerambycida;. He said 

 that by the addition of new species the definition of some of the genera of Ceramby- 

 cid.v becomes very vague. Among others he mentioned the genera belonging to the 

 tribe I/ndionesoi Lecordaire, to which the genus Ididion with three species has to be 

 added to our list and which seem to differ only from Compsu by the carinate hind 

 tibia;, a character which, if he remembered correctly, is not so very pronounced in some 

 of the Central American species. The distinguishing characters were explained by 

 him and the following table presented : 



Front coxal cavities closed behind ; joint 3-6 of antenna; carinate. 



Tibia; carinate Ibulion. 



Tibia: not carinate Compsa. 



Front coxal open behind ; antenn.al joints and tibine not carinate Hctirachthes. 



He mentioned further that ISates, in Biol. Centr. Amer., referred all of the Cen- 

 tral American species to Ibidioit, of which some evidently would fall either in Compsa 

 or Ileterachthcs. All of the species known to occur in our fauna were exhibited by 

 him with the exception of //. nohilis. The three species of Ibidion are /. cxclavia- 

 tionis, tmc'sendi and textile var. alacrc, all three from Brownsville, Texas. 



He also exhibited a specimen of the true 9 of ^^ white ant, 'J'ertnis Jlavipes, 

 the capture of which he had recorded in one of the previous meetings ; also the 

 piece of wood out of which the queen was taken. 



His collection of Cassidini were then shown by him with a series of the newly- 

 discovered Cassida viridis* from Canada, concerning which he remarked, that from 

 what he was able to gather from the references within his reach, he takes to be the 

 European Cassida viridis contrary to the views of Messrs. Wickham and I.iebeck, 

 who identified it as C. thoracica as one of his correspondents had informed him, and 

 that Rev. Dr. Fyles who first took the species and recorded it in the (."anadian Ento- 

 mologist as C. viridis, was right in his identification. 



Adjourned. 



* Specimens of this species were exhibited by me at a previous meeting, and were 

 pronounced, by Mr. Schaefler, not to be C. viridis. The identification, however, 

 seems to have been correct. — W. B.
