without doubt is identical with miscecristatella. For differentiation 

 from tricing ulatella I refer to that species. 



H. tricingulatella Clem.— Dyar's List, p. 572. No. 6524. — Palpi whitish, 

 dusted with fuscous externally aud with a dark fuscous spot on second and third 

 joint above. Head sordid white, intermixed witli fuscous above. Antennae 

 fuscous. Thorax gray, patagia dark fuscous anteriorly. Forewings narrow, 

 margins, especially the costal, nearly straight, subparallel ; grayish white dusted 

 and speckled with fuscous ; extreme base, a fascia at one-fifth ; a second one, 

 more oblique, before the middle, a third fascia at two-thirds, curved, sinuate 

 within ; these three fascia reach the inner margin more or less distinctly, beyond 

 the third fascia are three costal and three corresponding dorsal spots, forming 

 more or less distinct, transverse bands; both margins are more or less dotted 

 between the fascias; a dark spot at the apex, a pair of dark brown scale tufts 

 along the inner margin of first and second fascia, the lower tuft being the larger ; 

 a tuft on the anterior margin of third fascia, all these tufts are faced with silvery 

 white scales within. Cilia grayish, with a broad, peri-apical, dividing line near 

 the base, barred with short white Hues which proceed from the white lines 

 between the apical marginal spots. Hindwings pale grayish fuscous, with feeble 

 brassy lustre. Abdomen dark fuscous brown above, underside fuscous mixed 

 with white. Anterior and middle legs whitish, spotted with dark fuscous, pos- 

 terior legs grayish fuscous. 



Exp. 10.0 mm. ; 0.4 inch. 



Hub. — Pennsylvania, New Jersey (Essex County). 



My friend, Mr. A. Busck, considers this species identical with 

 the preceeding. A view I cannot share. I have again made 

 careful comparisons of the type, which is in good condition in 

 the Academy of Natural Sciences, Philadelphia, with well authen- 

 ticated specimens of H. miscecristatella and can reach but one con- 

 clusion, that they are distinct, though closely related. The wings 

 in tricingulatella are distinctly narrower, margins almost parallel, 

 the upper tuft of median fascia scarsely as large as the lower and 

 immediately above it, while the lower one is further outwardly in 

 m Iscecristate I la. A specimen in my collection, received from Mr. 

 W. D. Kearfott, is identical with the type. 



Subgenus STEXOPTIKEA. 



Characters, those of Homosetia proper, except that veins 5 and 6 

 of hindwings are stemmed. The hairs of the vertex project forward 

 in form of a tuft which is met by the ascending hairs of the face. 



The two species here recognized are the smallest Tineids with plicate 

 maxillary palpi known to me, and may be distinguished as follows: 



Apical part of forewing and cilia not pale ornatella. 



Apical part of forewings and cilia buff brown auriferella.
