ii. — L. crateegella Clem., he. cit. 



All of my specimens have a very pronounced though rather short white 

 dorso-basal streak, which is sometimes continuous - with a longitudinal 

 median white streak upon the thorax, and in all of them the median basal 

 streak is continuous with a white line across the anterior margin of the 

 thorax, which is extended backwards over the tegulae. The dorso-basal 

 streak and the markings of the thorax and tegulae are not mentioned by 

 Dr. Clemens. But these thoracic markings are very variable in a great 

 many species. In some specimens ot some species no trace of them is 

 visible ; in others they are very faint : and in others thev are pronounced 

 and distinct. 



The larva mines the leaves of the Apple. Wild Cherry ( Primus sero- 

 tina), Haw (Crataegus) and Sweet scented Crab (Pyrus coronariaj, on 

 the under side. It is of the first group, and the mine is tentiform. Dr. 

 Clemens records of it. that it quits one mine to form another — in- which 

 it is singular. 



There is considerable variation in the shades of coloring, some species 

 being much more golden than others, and the same specimen varies in 

 this respect with the light. Al. ex. A to -/V inch. 



Common in Kentucky, and probably wherever in America its food 

 plants are found. 



Sub.-div. c. No apical spot. Apex dusted. 



* No basal streak. 



t No fascia, but with dorsal and costal streaks. 



12. — L. nonfasciella. N. sp. 



Face and palpi white, tuft white, mixed with pale golden ; antennae 

 white, each joint tipped with fuscous above ; thorax and anterior wings
