CHAMBERS ON FOOD-PLANTS OF TINEINA. 117 



of the leaves, from which it eats out the parenchyma between the cuticles. 

 (Similar to the habit of Butalis matutella ou leaves of Ambrosia trifida 

 and Asters.) 



SOLANACEJ3. 



Solanum carolinense. Horse Nettle. 



Gelechia solaniiella, Cham. Larva in a small blotch mine. 



Physalis viscosa. Ground Cherry. 



Gelechia pkysaliella, Cham. Larva in a tentiform mine in the under 

 surface. 



Gelechia physalivorella, Cham. Larva feeds on the leaves in a way not 

 yet discovered. A larva, probably of a Laverna, burrows in the stem in 

 Colorado, causing a fusiform swelling. 



NYCTAGINACE.E. 

 ABRONIA FRACxRANS. 



Lithariapteryx abroniwella, Cham. Larva mines the leaves, frequently 

 leaving one mine to make another. Imago common about the plant in 

 July and August in Colorado. 



CHENOPODIACE^J. 



Chenopodium and Atriplex. Goosefoot. 



Gelechia hermanella, Fab. Larva mines the leaves, making an irregu- 

 lar, somewhat serpentine, track, with scattered "frass". 



LAURACE^E. 



Sassafras officinale. Sassafras. 



Gracilaria sassafrasella, Cham. Larva, when very young, mines the 

 leaves ; older, it rolls them downward. 



ULMACE.E. 



TJLMUS AMERICANA. Elm. 



Lithocolletis argentinotella, Clem. Larva makes a tentiform mine in 

 the under side of the leaves ; rarely in the upper side. 



Lithocolletis ulmella, Cham. Larva makes a flat mine in the upper 

 side of the leaves. 



(Argyresthia austerella Zeller, I am convinced, feeds in some way on 

 it; and in latter May and in June the imago may be found about the 

 trees.) 



Celtis occidentalis. Hackberry. 



Lithocolletis celtisella, Cham. Larva in a blotch mine showing about 

 as plainly on one surface as on the other. Very abundant.
