§ 31. Insect Deformities. Mr. H. K. Morrison showed 

 a specimen of Erynnis icelus^ which had a nick in the front 

 margin of each fore-wing, perfectly symmetrical on the two 

 wings. It seems as if the pupa must have received some wound 

 just at the point where the two fore-margins meet, which cor- 

 responds to the position of the notches on these wings.

* 955. Ja: S. Johnson. A season's collecting in Cato- 

 cala. p. 64-66. [Dec, 1877.] 



About 446 specimens of 29 species of Catocala collected [at Frankford, 

 Pa.] between 9 July and 10 Oct., 187 7, as follows: 



The search began 20 June, but no specimens were fou7id until 9 July. In 

 pleasing contrast to the ways of sham scientists who collect only good spec- 

 imens or uncommon species, Mr. Johnson collected all the specimens he 

 could get.
