President Longley read the opinions of authors as to the 

 cause of mimicry. Messrs. Comstock exhibited specimens of 

 Limcntis /loridcnsis and pointed out the fact that this insect 

 took the color of .-hiosia berenice which seems to be the com- 

 monest Anosia in Florida during the summer. Some protected 

 exotic butterflies, such as Hebomoia glaucippe, Hypolimnas nii- 

 sippi/s, A'nosia c/irysippits, etc., were also shown. Mr. Schwart/, 

 exhibited some interesting L,epidoptera mounted on plaster of 

 paris casts. He showed a specimen of Pliyllinni scylhc from 

 Ceylon that resembled a clump of guava leaves. These speci- 

 mens were from the exhibit of Dentori Bros. The meeting 

 adjourned at 9.35 P. M., after which the members viewed the 

 different exhibits. 



JOHN COMSTOCK, Secretary. 



The twenty-third regular meeting of the Harris Club was 

 held at 35 Court Street, Boston, on the evening of January 14, 

 1902. President Newcomb in the Chair. Dr. L. O. Howard 

 spoke informally on opportunities for useful work in Entomo- 

 logy. Mr. Kirkland told of the damage done to willows and 

 poplars in the vicinity of Boston by Saperda co>/ro/<>r, and 

 showed a photograph illustrating the work of this insect in 

 Populus trcmnloides, with punctures made by downy wood- 

 peckers in their search for the borers. The work of this insect 

 differs from that of Cimbc.\ in that the slit made in the bark by 

 the ovipositing ? is not straight, but horse-shoe shaped. In 

 the discussion which followed, Dr. Howard called attention to 

 the symbiotic relation between this Cimbcx and the willow- 

 shoot horn tail, rhylloccus integer. The latter, preferring dy- 

 ing stalks to healthy ones, oviposits by preference in shoots 

 already injured by the attack of Cimbe.\-. The genus Tl, 

 was discussed by various members, who exhibited specimens. 



Officers were elected for the ensuing year as follows Presi- 

 dent, P. G. Bolster ; ist Vice President, \V. !'. Low ; 2cl Vice 

 President, \V. D. Denton ; Secretary and Treasurer, \Y. I,. \Y.
