116 BULLETIN UNITED STATES GEOLOGICAL SURVEY. 



Gelechia dubitella, Cham. Larva folds a leaf so as to form a case, in 

 which it feeds. 



Gelechia chambersella, Murtfeldt. Larva feeds externally on the leaves. 



Heliopsis (various species). Oxeye. 



Tischeria heliopsisella, Cham. Larval habit as in Ambrosia trijida 



(supra). 



Helianthus (various species). Sunflowers. 



Lithocolletis ambrosiccclla, Cham. Larval habit as in Ambrosia trijida 

 (supra). 



Lithocolletis helianthivorella, Cham. Larval habits as in the last 

 species (ambrosicvella); that is, it lives in a tentiform under-side miue. 



Glyphipteryx montisella, Cham. Imago found on the flowers in Au- 

 gust. Larva unknown. 



Euechtites hieeacifolius. Fire- weed. 



Phyllocnistis erechtitisella, Cham. Imago unknown. Larva in a long, 

 narrow, linear, winding mine in upper surface of the leaves. 



AQUIFOLIACE^. 

 Ilex opaca. Holly.* 



Cryptolechia cryptolechiella, Cham. Larva sews together the leaves. 

 (Having only a leaf, I am not certain of the plaut.) 



EBENACE.E. 



Diospyros virginiana. Persimmon. 



Aspidisca diospyriella, Cham. Larva in a minute blotch mine, from 

 which it cuts out a case in which it pupates. 



PEIMULACE.E. 

 Lysimachia lanceolata. Loose-strife. 



Lithocolletis lysimachiceella, Cham. Imago unknown. Larva in a small 

 tentiform mine in under surface of leaves. 



LABIATE. 



Scutellaria (various species). Skullcap. 



Gelechia scutellariceella, Cham. Larva in a case attached to the under 

 side of the leaves, and from which it mines out the parenchyma between 

 the cuticles. 



CONVOLVULACE.E. 



Ipomea and Pharbites (various species). Morning Glory. 



Bedellia somnulentella, Stainton. Larva makes a web on under side 



* In Washington, D. C. in January, I have found empty mines of two species of Ti- 

 neina, both of which are undescribed. They were found in leaves of different species 

 of Holly. One mine is probably that of a Lithocolletis larva, of the flat group, in leaves 

 of /. opaca. The other is probably that of a Nepticula, and was in leaves of another 

 species.
