not bred the moth from it. It is very different from another Helianthus 

 mine yet to be described. The cocoon is fusiform, suspended in the mine 

 by a thread from each end. So is the cocoon of the large Helianthus 

 mine, and the larva only differs from this by wanting the fuscus marks 

 about the head. But the mine is very different and resembles on the 

 upper side a tubercular swelling of the leaf. I have not yet bred the moth 

 from either Helianthus mine. I once found a large mine differing from 

 all of these, but with the same "kind of cocoon on the under surface of a 

 weed ( Eupatorium 1 ) at Macon, Georgia. 



20. — L. celtifoliella. N. sp. 



Face and palpi silvery white, the palpi on their outer surfaces saffron. 

 necked with brown. Antennae brown, annulate with white and flecked 

 with blackish scales. Tuft reddish-saffron with white scales intermixed. 

 Thorax reddish-saffron anteriorly, passing into brown towards the apex, 

 sparsely flecked with white, and with the usual white line (sometimes 

 absent) across the anterior margin produced backwards over the teguke 

 and on to the wings, where it is confluent with a narrow median white 

 basal streak which is strongly dark margined dorsallv, the dark margin 

 being produced beyond it nearly to the middle of the wing. Anterior 

 wings reddish-saffron, the dorsal margin nearly to the ciliae thickly dusted 

 with dark brown on a white ground, and with a streak of dark brown 

 extending to the basal streak not far from the base. Three fasciae, rather 

 indefinitely bounded, of dark brown upon a white ground ; all strongly 

 angulated posteriorly about the middle, the third one slightly interrupted 

 near the costa and passing gradually into a costo-apical patch of dark 

 brown on a white ground. The first fascia is just before the middle ; the 

 second is about the middle and each sends a white streak from its angle 

 nearly to the next fascia. There is a dorso-apical patch of dense dark 

 brown dusting on a white ground, larger than the costo-apical one above 

 mentioned. Cilias pale reddish-saffron with a dark brown hinder marginal 

 line in the ciliae. (Sometimes almost the entire thorax and dorsal margins 

 of the wings are densely dusted with dark brown on a white ground, whilst 

 the first and second fasciae blend with each other near the dorsal margin, 

 and the third fasciae blends with the dorso-apical dusting. It varies in the 

 extent and intensity of the dusting). Under surface silvery white with a 

 patch of dark brown dusting on each side of each abdominal segment. 

 Legs silvery white with the anterior tibiae and tarsi reddish-saffron dusted 

 thickly with dark brown, and the intermediate and posterior tibiae and tarsi 

 spotted and annulate with dark brown.
