brilliant than those bred from Desmodiara, and has the dark margins 

 of the fascia less distinct. Otherwise, I have not noted any difference- 



LiTiioc'oLLETis CELTiSELLA, Cham., aud L. TRiT^NiAELLA, Cham. 



I have heretofore referred the larvae of these species to tlic " flat 

 group," having been misled by somewhat hasty observations on the 

 mines found on the upper surfaces of the leaves. In fact, both belong- 

 to the " cylindrical group," the larva? of which are flattened in their 

 first three stages, and cjdindrical in the last four. The mine of tritce- 

 niaella is confined to the upper surfaces of the leaves of its food-plant 

 [Ostrya), and is large, roomy and white. The mine of celtisella begins 

 on the under surface of the leaves of the hackberry (Celt is), where it 

 is long, linear and crooked; but afterwards the larva eats through the 

 parench^'ma to ihe upper cuticle of the leaf, where it makes a flat, 

 blotch-like mine, which is then made tentiform by a small fold of the 

 cuticle. The larva of L. tritosniaella is deeply stained with fuscus — 

 in fact, is almost black, being the only larva of the cylindrical group 

 known to me which shows that color. 



LiTHOCOLLETIS SOLIDAGINISELLA, U. Sp. 



From Mr. W. H. Patton I have received a single specimen of a species 

 bred by him, in Connecticut, from a larva mining a leaf of Solidago 

 patula. He was not able to inform me which group the larva belonged 

 to, nor which surface of the leaf was mined by it. The species is not 

 at all closeU^ allied to any of our species heretofore described, and no 

 Solidago feeding species of this genus has heretofore been described. 

 L. basistrigeUa, Clem., is, perhaps, its nearest American compeer, and 

 is of about the same size. SoIidaginiseUa, however, has but a single 

 basal streak on the forewiug, and that one is placed beneath the fold, 

 and extends only to about the basal fourth of the wing length. Ver- 

 tical tuft, thorax, and upper surface of the forewings pale golden yel- 

 low. On the forewings are four silvery white costal and two dorsal 

 streaks. The first two costal streaks are oblique, pointing backward, 

 while the last two point obliquely forward; and all four are rather 

 short, aud all are dark margined behind, except the first, which is unmar- 

 gined; the second and third would, if projected, meet so as to form an 

 obtuse angle about the middle of the wing, where also they would 

 meet the first dorsal streak. The first costal streak is placed a little 

 behind the basal fourth of the wing-length. Tiie two dorsal streaks 

 are longer than. the costal ones, and point obliquely back, so that the
