internall}' with black. At apical fourth, between the last costal streak 

 and apex, is an oval black spot with the center white and the entire 

 costal edge is sliohtly mottled with black. Cilia dark fuscous with a 

 whitish line parallel with the dorsal edge. Hindwings and cilia dark 

 g-ray. Abdomen dark fuscous, anal tuft yellowish. Legs silvery 

 yellow; tarsi Avith black annulations. 



Alar expanse, 7.6 to 8.4 mm. 



Described from 3 specimens, bred from Seba^tlania lac'ida^ collected 

 by Dr. Dj^ar at Palm Beach, Florida.

Larva makes a ))rown, irregular, elongated upper Ijlotchmine, with 

 the upper epidermis drawn into a longitudinal ridge. It leaves the 

 mine and spins its white cocoon in a sharp fold at the edge of the leaf. 



PHYLLOCNISTIS Zeller. 



Of the American species placed under this genus P. amjpelopsiella 

 Cham])ers, Viriodendronella Clemens, iwjndiella Chambers, mtifolieUa 

 Chambers, vitujeneUa Clemens, and llquidamberisella Chambers all 

 conform well with the definition of that genus. So does P. magnoUa- 

 eUa Chambers, the imago of which has never been described, but which 

 I have hvvA and found to be a distinct species. 



P. f<inilacisella Chambers is known only from the mine, and is 

 unknown to me except from description. 



The imago of P. erechtitiseUa Chambers has never been described, 

 but I have bred a large series of it from Erechtites hieracifoUa. I 

 have also a large series of P. insignis Frey and Boll bred from Seiiecla 

 aureus. The mines of both are among the earliest found in spring, 

 and several generations are produced during summer until late fall. 

 The insects overwinter as imago like the other species of the genus. 

 Living material of both is now before me, and 1 am unable to find 

 any difierence between them in any stage. Frey's name must stand. 

 Dr. Edward Meyrick, of England, has kindly called my attention to 

 the fact, that this species is not a true Phyllocnistis, according to the 

 present definition of that genus. P. insigms has the antennae some- 

 what longer than the forewings instead of somewhat shorter, and the 

 basal joint is in no way dilated into an eyecap. Frey says about his 

 type of this species: "Wirglauben iiber die generishe Stellung des 

 reizenden Thierchens uns nicht zu taiischen," and gets out of the 

 difiiculty l)y stating: ''Fiihler defect." 



Otherwise, in venation, characters of the palpi, head and posterior 

 legs, it agrees perfectly with Phyllocnistis and the general pattern of 

 the wings is also much like this genus. 



As th(^ early stages and the work and hal)its of this species are also 

 identical Avith those of the genus, I should propose to widen the defi- 

 nition of Phyllocnitis rather than to erect a new genus, the more so
