SUPERFAMILY GELECHOIDEA 163 



empty mines. It mines the under surface, and produces a tubio- 

 ular swelling of the upper surface. It pupates among leaves on 

 the ground, and (in the breeding cage at least) the imago conceals 

 itself among the leaves and "trash" on the ground. I have never 

 seen any specimens except the two that I succeeded in rearing; 

 but the mines are abundant. The following are my notes about 

 the larvae: "Larvae now (October 6th) about f inch long; one of 

 these in the mine appears bright bluish-green, with the head 

 yellowish; another is pale bluish or bluish-green, almost white, 

 suffused with pink upon the back, head pale brownish. October 

 7th, one of them has left the mine; it is J inch long, robust, deep 

 purple, with the head and 'shield' of the first segment green. Two 

 imagines, April 14." 



Miss Braun added: 



The species is by no means common. I have reared a small 

 series of specimens from larvae collected May 28 in Powell County, 

 Kentucky, on young plants of an undetermined species of Physalis. 

 The leaves of this plant are thin in texture, and the character of 

 the mine is different from that described by Chambers in leaves 

 of Physalis viscosa. The mines are at first linear and contorted, 

 later blotch-like, with most of the leaf substance consumed. 



These records are both from Kentucky. 



Chrysopora 



Our two species of this genus mine the leaves of members 

 of the goose-foot family Chenopodium and Atriplex. A good 

 description of the larva and mine of one of them was given 

 by Chambers (1872) as follows: 



I have found it mining the leaves of species of Chenopodium in 

 Kentucky and Wisconsin. The larva, at first, is white; but 

 towards maturity, eight crimson spots make their appearance on 

 each segment; four on top and two on each side. (Stainton says 

 four, but in all of my specimens there are eight.) Sometimes 

 some of the spots are confluent. It enters the leaf from the upper 

 surface, and frequently leaves an old mine to construct a new one.
