back ; at the apical third, a triangular costal spot and opposite it, a 

 much smaller dorsal spot: just before the apex, a small white costal 

 spot. Apical cilia white ; cilia below the apex gray with a line of dark 

 scales through their middle, extending to the tornus. Hindwings dark 

 brown. Abdomen dark brown, underside whitish, except near the 

 thorax and at the bases of the segments. Legs black, with silvery an- 

 nulations of varying width. Expanse: 5-5.5 mm. 



This species was named by Chambers from the mine only, 

 and erroneously referred to the genus Thyllocnistis. Cham- 

 bers states (Cin. Quart. Jn. Sci. II. 108. 1875) tnat ne found 

 the mine only in Southern Kentucky on the leaves of Siniln.r 

 glabra and never met with it in Northern Kentucky. 



The three minees which produced the moths from which the 

 above description was prepared, were found at Cincinnati, 

 Ohio, August 3 ist, on the upper side of leaves of Smila.r 

 hispida Muhl. The mine is silvery white, narrow, even in the 

 later stages not more than 2.5 mm. wide, with a narrow cen- 

 tral line of frass. Its course is very winding, crossing and 

 recrossing the earlier portion of the mine, and covering in the 

 case of the smaller leaves almost the entire surface of the leaf. 



The larva at maturity turns bright red, and leaving the mine, 

 spins the peculiarly ornamented cocoon characteristic of the 

 genus. 



The cocoon, which is yellowish white, with a group of iri- 

 descent globules at each end, is spun in a small fold at the 

 edge of the under side of the leaf. 



The imagoes appeared September 23d and September 29th. 

 In two of them, the fascia at the basal third is complete, in the 

 third, it is represented only by the dorsal spot.

Several specimens of this species were bred from the flat 

 white fungus which often covers large portions of the trunks 

 of dead and partially burned beech. 



The larva is a case-bearer and feeds externallv on the fun-
