slightly interrupted in the middle, and is narrowly dark-margined poster- 

 iorly; (on one wing it is not interrupted, but it is angulated and produced 

 posteriorly) ; another rather wide fascia of the same hue, before the cilice 

 slightly produced along the base of the dorsal cilice. An apical brown 

 streak and a costo-apical streak (of the same hue as the fasciae), which 

 reaches the inner end of the brown streak and is there bent backwards 

 passing around the end of the brown streak, and in a direction nearly 

 parallel with it to the dorsal cilice just behind the apex. Hinder marginal 

 line at the base of the apical cilice golden brown. Cilice pale golden. 

 The specimen from S. lo?igifolia is scarcely at all dusted, the markings 

 are paler and narrower, though similarly disposed, and the white ground 

 colour is not so marked as in the other, but I have no doubt they 

 are of the same species. 



2p. L. juglandiella. 



Dr. Clemens (loc. cit.) names this species also from the larva which 

 he found mining the upper surface of leaflets of the Black Walnut (Juglans 

 nigra), and Dr. Packard refers to it in the same way as to the last named 

 species. Dr. Clemens suggests the probability that it may be identical 

 with L. caryaefoliella. I have never found it on the Walnut, but have 

 occasionally, though rarely, found it in the leaves of the Butternut, (yuglans 

 cinerea), and judging from the larva, without having bred the imago, I 

 have no doubt that it is L. caryaefoliella. Clemens, ante p. log.

1 have not succeeded as yet in getting this species from the mine, and 

 have never seen the imago. But I have found on the upper surface of 

 leaves of the White Oak ( Quercus alba) a larva and mine which I believe 

 to be the same described by Dr. Clemens. It is a long, rather narrow 

 band, gradually widening, in which the larva lies transversely, eating first 

 upon one and then upon the other side, so that the frass is deposited in a 

 narrow line along each side. Dr. Clemens has alluded to the peculiar 

 appearance of the larva, which in fact differs from the ordinary flat Litho- 

 colktis larva, as much as that does from the larva of the first group (cylin- 

 drical). It is considerably larger, vertically thicker, depressed but not flat, 

 the head is more obtusely rounded in front, and the sides of the segments 

 are more distinctlv mamillated. The cuticle is sleek and shining. It is 

 white, with the alimentary canal nearly colourless or watery, and the con- 

 tents of the body on each side of it white and granular. It remains much 

 longer in the larval state than the other species, and hence is much more
