This species is a miner on the upper side of Cratacgus 

 tomentosa L. in Kentucky, according to Chambers, and in 

 Ohio on Crataegus mollis (T. & G.) Scheele, from which I 

 have bred it. The thin loosened upper epidermis of the almost 

 circular blotch is yellowish white, sprinkled with frass. Later 

 the epidermis becomes wrinkled to such an extent that the leaf 

 is often almost folded double. At the time of pupation, the 

 larva leaves the mine, and spins on the middle of the upper 

 surface of the loosened epidermis a reddish yellow cocoon 

 which is speckled with brown, exactly like the spots on the 

 epidermis. Without very careful observation, this creates 

 the impression that the cocoon is within the mine, as Cham- 

 bers described it. The epidermis is attached to the lower sur- 

 face and sides of the cocoon, this process often tearing the 

 epidermis at each side, and the upper side of the cocoon does 

 not project above the general level of the mine. The pupa, 

 on emergence, does not project through the epidermis of the 

 mine, but through the upper side of the end of the cocoon. 



O. Inusitatumella is most nearly related to 0. pnmivorella 

 Cham., from which it differs by its smaller size, more distinct 

 striae and the absence of the patch of semi-erect scales on the 

 middle of the dorsal margin.

Head and face silvery gray, except the vertex which has a few fus- 

 cous scales Antennae shining brownish gray. Labial palpi silvery 

 white, the apex of the second joint beneath somewhat roughened with 

 dark brown scales, terminal joint with a dark brown annulation near the 

 tip. Maxilary palpi dark blackish brown. Thorax dark brown. Fore- 

 wings dark brown, somewhat mottled, in some lights with a deep blue 

 iridescence. The markings which are silvery white are somewhat varia- 

 ble. At the basal third is a perpendicular slightly curved silvery fas- 

 cia ; this is, however, sometimes reduced to a white dorsal spot, reach- 

 ing only to the fold. At the middle of the costa is an oblique curved 

 white spot sometimes reaching to the middle of the wing, where its 

 apex is opposite that of a triangular dorsal spot, situated a little farther
