the beginning of June ; the imago appeared July 25th. The 

 later larval habits are very similar to those of G. salicifoliella 

 Cham. The larva enters the leaf by means of a lunate slit 

 or. the under side, and makes a large flat upper surface mine. 

 It later deserts this mine to form a new one. At no period 

 of its larval existence is it a leaf-roller. This sharply distin- 

 guishes it from G. stigniatclla Fab., which the imago in many 

 respects resembles. The larva spins an oval, flat, somewhat 

 glaucous silk cocoon on either the upper or lower side of the 

 leaf.

The Larva of Eumaeus atala. 

 BY JOHN L. HEALY, Chicago, 111. 



That the larva of so common a butterfly as is E. atala about 

 Miami, Florida, should be overlooked is rather remarkable. 

 On the rock ridge, some three miles wide, between Biscayne 

 Bay and the Everglades, where the principal features of the 

 flora are jack-pine and palmetto, this beautiful little black and 

 orange creature is very abundant. My trip to Miami was 

 solely on business and no time was available for strictly ento- 

 mological pursuit. While on my way to the Everglades to 

 inspect some land in the company of unscientific and unsym- 

 pathetic persons, I observed such numbers of this species that 

 I prevailed upon my companions to spend a few minutes 

 watching me catch a few. I am always armed with a folding 

 net and a cyanide jar. Noticing the female ovipositing on a 

 species of fern I determined that some brightly colored larvae 

 on the same plant were probably the larvae of atala. I secured 

 two, and also three pupas, so closely resembling the larvae 

 that no mistake could be made. Eggs, larvae, pupae and ima- 

 goes were all present in great numbers. I had no glass with 

 which to observe the eggs, nor any proper receptacle in which 

 to carry them, so made no detailed observations. 



The mature larva is about one inch in length, robust, bright 

 vermilion red in color ; thorax much lighter, yellowish, semi-
