President Longley read the opinions of authors as to the 

 cause of mimicry. Messrs. Comstock exhibited specimens of 

 Limentis floridcnsis and pointed out the fact that this insect 

 took the color of Anosia bcreiiicc which seems to be the com- 

 monest Anosia in Florida during the summer. Some protected 

 exotic butterflies, such as Hcbomoia giaudppc, Hypolimnas mi- 

 sippus, Anosia chrysippus, etc., were also shown. Mr. Schwartz 

 exhibited some interesting Lepidoptera mounted on plaster of 

 paris casts. He showed a specimen of Phyllhwi scythe from 

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

 mens were from the exhibit of Denton 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 covcolor, and 

 showed a photograph illustrating the work of this insect in 

 Populus tremuloides, with punctures made by downy wood- 

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

 differs from that of Cimbcx in that the .slit made in the bark by 

 the ovipositing 9 is not straight, but horse-shoe .shaped. In 

 the discussion which followed, Dr. Howard called attention to 

 the symbiotic relation between this Cinibex and the willow- 

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

 ing .stalks to healthy ones, oviposits by preference in shoots 

 already injured by the attack of Cimbcx. The genus Thecla 

 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, W. F. Low ; 2d Vice 

 President, W. D. Denton ; Secretary and Treasurer, W. L. W. 

 Field.
