rather long and distinct ; subcostal simple, and obsolete from the middle to 

 the base ; discoidal cell unclosed, with an independent discal nervule, faintly 

 indicated from the base, and furcate at the apical third. The median strongly 

 indicated and bifid rather beyond the middle of the inner margin. 



E. s imu 1 atr ic el la . Head brownish ochreous. Antennae ochreous, 

 annulated with dark brown. Fore wings dark brownish, with a white band 

 about the basal third of the wing, a white spot on the costa, near the middle, 

 and one on the inner margin, a little behind it, and a white transverse streak 

 near the tip. Hind wings dark brown ; cilia the same. 



This insect has considerable resemblance to an Incurvaria. Its neuration, 

 however, places it in a very distinct group. 



Antispila Herrich-Schaffer, Frey. 



A. Ny saef o 1 i ella . Head above dark brown. Face, labial palpi, and 

 fore feet shining yellowish ochreous. Antennae dark brown ; basal joint yellowish 

 ochreous. Fore wings dark brown, with a greenish reflection, and the base 

 with a bright coppery hue. Near the base is a rather broad, bright golden 

 band, broadest on the inner margin, where it is nearest the base, and con- 

 stricted at the fold of the wing ; a spot of the same hue on the costa, at the 

 apical third of the wing, and one on the inner margin, midway between this 

 and the band ; cilia somewhat coppery, and rather grayish at the inner angle. 

 Hind wings purple brown ; cilia grayish ochreous. 



The larva mines the leaves of Nysa multiflorain September. The head 

 is dark brown ; first segment dark brownish ; body very pale green with dark 

 atoms along the dorsum ; ventral surface with a line of two black spots. After 

 the last molting the first segment is black, and the dorsal spots become a 

 black, vascular line. When full fed, the larva weaves an oval cocoon within 

 the mine, and cutting the two skins of the leaf into a correspondent form, 

 permits it to fall to the ground. There is thus left an oval hole in the de- 

 serted mine. The imagos appear during the following May. 



A. co r n if oliella . Head, face, labial palpi, and fore feet dark brown. 

 Antennae dark brown ; basal joint somewhat ochreous. fore wings rather 

 dull dark brown, with a coppery hue. Near the base is a rather narrow, 

 golden band, not constricted on the fold, and rather indistinct toward the costa, 

 where it is somewhat suffused with a coppery hue, and nearest the base on the 

 inner margin. At the apical third of the wing is a small golden spot, and 

 nearly opposite, on the inner margin, another of the same hue, with the 

 hinder portion of the wing tinged with a bright reddish coppery hue ; cilia 

 dark grayish. Hind wings purplish brown ; cilia somewhat paler, with a cop- 

 pery hue. 



The larva mines the leaves of Cornus florida, in September. It'may pos- 

 sibly be a variation of Nysaefoliella. The larvae of the insects are very 

 like each other, but I don't know whether that ofCornifoliella undergoes 

 the same change of coloration after the last molting as that of Nysaefoli- 

 ella. The head and shield dark brown ; body nearly white, with seven 

 minute, black points along the dorsum, and eight on the ventral surface, 

 somewhat larger, and more distinct. Its mode of preparing for pupation is 

 the same as the previous species, but whilst the individuals of Nysaefoli- 

 e 1 1 a on a single tree are almost innumerable, those ofCornifoliella are 

 not abundant. 



Aspidisca. 



Fore wings with no discoidal cell. The subcostal nervure traverses the 

 middle of the wing, attenuated from the base to the basal third, where it gives 

 origin to a long, marginal branch, which reaches the costa at the apical third 

 of the wing ; near the tip it subdivides into three short branches, one of which 

 is delivered to the costa behind the tip, one to the tip, without attaining the
