i9 2 ENTOMOLOGICAL NEWS [April, '12 



Society at the Centenary of the Academy of Natural Sciences 

 of Philadelphia, to be celebrated March 19, 20 and 21. 



Mr. Laurent called attention to Circular 144, U. S. Dept. 

 Agric., and said he was not previously aware that Scolytus 

 quadrlsplnosus injured the small stems and buds of the hickory. 



He also read a newspaper clipping, dated Woodbury, N. J., 

 January 3Oth, which read as follows: ". . . According to 

 fruit experts the yield of South Jersey the coming season 

 ought to be a record breaker. These men declare that when 

 the trees have a coating of ice once during the winter the fol- 

 lowing season is prolific in the yield as the ice kills any pests 

 that may have clung to the bark. Thus far there have been 

 three sleet storms, and at present every tree in Gloucester 

 County has a half-inch ice coating." The speaker asked 

 whether it was a fact that ice kills scale and other bark insects. 



Dr. Skinner made some remarks on the so-called Pharma- 

 cophagus Papilio, P. phileiwr and its alleged mimics, Papilio 

 glaucus, polyxcnes and troilus. The records of birds attack- 

 ing these insects are very meager and it is doubtful whether 

 P. philcnor is poisonous or noxious to birds. A large amount 

 of careful experimental evidence will be necessary to prove that 

 the three species, in the female sex, mimic philcnor, and that 

 their markings were thus developed. 



Mr. E. T. Cresson, Jr., suggested that Dasyllis may mimic 

 the non-predaceous bumblebee so that it may deceive other 

 insects on which it feeds, the latter mistaking it for a bumble- 

 bee and not making an effort to escape. 



HENRY SKINNER, Sec'y.
