Doings of Societies. 



The Entomological Society of Western Pennsylvania held 

 its regular monthly meeting in Carnegie Museum, Pittsburg, 

 Pa., Monday evening, May 3, 1909, President W. J. Holland 

 presiding. Eleven members present. Director Holland ex- 

 hibited a collection of Cossidae and Hepialidae from Aus- 

 tralia, most all very rare species, some of which have just re- 

 cently been described. 



Mr. Robert Dickson exhibited a very interesting collection 

 of blown larvae of the wood-boring moths, all mounted in 

 their natural food burrows. Among these were Prionoxystus 

 robiniae, in locust, Sanninoidea e.vitiosa, in peach, Sesia accrni 

 in swamp maple, Sesia pyri, in apple, and Sesia pictipes, in 

 wild cherry, also larvae of the clothes moth Tincola bisselliclla 

 mounted in a piece of cloth. 



Mr. Henry Engel exhibited a lot of Arctia rirgo larvae, 

 which he has been feeding on lettuce on and off since last Au- 

 gust. Mr. Engel also stated that he had observed a larvae 

 similar to Gortyna feeding in Rninc.v obtiisifolius. No one 

 present knew what it was.
