CHAMBEES ON NEW TINEINA. 85 



separates it from quercicella as a distinct section, characterized by the 

 great length of the palpi, it is not necessary to refer to it further in this 

 connection. C faginella has the basal joint of the antennae yellowish- 

 ochreous, except a wide blackish line extending along its upper surface; 

 quercicella has "two black stripes in front"; and the species from Texas 

 and that from Missouri agree in this respect with quercicella. G. faginella 

 and also the Texas and Missouri specimens have the stalk of the antennae 

 ochreous-yellow, with two blackish lines extending along the upper side 

 of the basal half, and the remainder of the stalk has each alternate 

 joint blackish; quercicella has simply " a black line above, terminating 

 in black spots". In quercicella, the fore wings are "yellowish-brown, 

 varied with blackish irregular strias, chiefly from the costa, with a black 

 dot on the end of the disk"; faginella agrees with this description, ex- 

 cept that I should call the ground-color of the wings dull yellowish- 

 ochreous, as they are likewise in the Missouri specimen; while in the 

 Texas species the grpundcolor is paler, while the transverse stripes are 

 more distinct, showing also a tendency to become more confluent, espe- 

 cially about the end of the disk, where they present to the naked eye 

 something like a faint dark fascia; faginella has a more silky lustre 

 than the other species, though this may be owing to the fact that the 

 specimens are newer. 



In the Texan specimens, and in that from Missouri, there is no spot at 

 the end of the disk, and it is not distinct in faginella. In quercicella, 

 " the posterior margin is tipped with blackish, and the cilia are yellowish- 

 brown, containing two dark fuscous hinder marginal lines"; in faginella, 

 there is a row of blackish spots around the apex, and a single faint 

 brownish hinder marginal line in the cilia (which in the single specimen 

 before me are a little injured). In the Missouri specimen, there are five 

 very distinct blackish spots around the apex, and behind them in the 

 cilia are two distinct, brownish, hinder marginal lines. Indeed, the cilia 

 may be called brown, with a median, paler, hinder marginal line. Besides 

 the five distinct spots, there are other very faint ones, and the brownish 

 cilia are paler than the spots. The specimens from Texas agree in this 

 respect with that from Missouri. One of these I sent to Mr. Cresson for 

 comparison with Dr. Clemens's type of quercicella in the collection of 

 the entomological section of the Phila. Acad. Sci. (formerly American 

 Ent. Soc). After comparing them, Mr. Cresson informs me that it "is 

 not Psilocorsis quercicella Clem., which differs by having a rather broad, 

 distinct, dusky border on the apical margin of the anterior wings, other- 

 wise they look very much alike". 



The species are all of very nearly the same size — about eight to nine 

 lines in expanse of wings. Professor Zeller (Bei. z. Kennt. 1873, 40) iden- 

 tifies specimens received by him from Ohio and Texas with quercicella 

 Clem. His Texan specimens were collected in the saijie region of the 

 State from which I have received mine ; and as in two collections that 

 I have received from that region there is only one species, I think the
