occur in the Pyraustidae, Pyralididae, 

 Phycitidae and Crambidae. The Ptero- 

 phoridae do not have them. They are 

 found in the Tortricidae, Grapholi- 

 thidae, Tineidae, Plutellidae, Gelechii- 

 dae, Coleophoridae, Lithocolletidae, 

 Lyonetiidae, NepticuHdae and Microp- 

 terygidae. 



While it is possible that these spiny 

 areas will not prove of great value in 

 classification, it is somewhat suggestive 

 when a species as Apatelodes torrefacta 

 S. & A. lacks them ; while they are 

 present in genera placed on each side. 

 In such cases they may perhaps aid the 

 systematist. 



The following lists contain an enu- 

 meration of the insects which I have 

 examined for the spinv area, referred 

 to their families. Numerals indicate 

 the number of species examined.

Notes on Butterflies. — I have seen V. 

 antiopa lay eggs on white birch and " canoe '"- 

 birch this year, and as far as I know this is a 

 new food plant for the species. 



Papilio turnus is unusually abundant in 

 Brookline, Mass., this year, as well as at 

 Jaffrey, N. H., especially around ash-trees, 

 where I have seen many eggs laid in the past 

 few days, and almost without exception on 

 the higher branches of young trees.
