So ENTOMOLOGICAL NEWS. [March, 



was dwelt on as an unusual character. In the female the maxil- 

 lary palpi are 2-jointed, in the male 3-jointed; the presence of 

 these palpi was apparently not before noted in the Sesiidae. The 

 difficulty of inducing the sexes of this species to mate was men- 

 tioned, and although eggs were laid within twenty-four hours 

 after the insect emerged from the pupa, none were fertilized. 

 The females possess eight ovarian tubes, each containing about 

 sixty eggs. Mr. Wenzel remarked on the apparent seldomness 

 of copulation in the peach-borer. Dr. Skinner spoke on the 

 extensile structure of the club of antenna of butterflies, espe- 

 cially in regard to a species of Argynnis, in which a telescoping 

 of that part was noticed. He presented to the Social on behalf 

 of Mr. Geo. B. King, of Lawrence, Mass., a series of microscop- 

 ical slides containing coccids from ant's nests. He also referred 

 to the care of specimens from pests, etc. Napthaline is fatal to 

 pests if the boxes be perfectly tight; otherwise it is likely to be 

 ineffective. 



Mr. Aaron mentioned the efficacy of bisulphide of carbon in 

 destroying pests. The fumes will kill all stages but the egg. 

 He further spoke on the habits of Neoclytus erythrocephalus and 

 Elaphidion. Discussed by Messrs. Smith, Johnson and Laurent. 



Mr. H. Wenzel reported the capture of thirty specimens of 

 Casnonia ludoviciana at Camden, N. }., on January 29; also two 

 larvae of probably Pyractomena lucifer. 



Mr. S. Frank Aaron was nominated for membership.
