AMERICAN LEPIDOPTEUA. 181 



may be correctly referred to that species. They differ from roxeositffu- 

 selfa in their smaller average size; but a knowledge of their larval habits 

 is necessary to establish this as a distinct species and to contribute to a 

 general revision of the group to which they belong. 



G. (Ergatis) pudibundetta , Zell. Verb. z.-b. Ges. Wien. 1873, p. 273, 

 must be at least very closely allied to this species ; but I have not seen 

 the type.

Gelechia absconditella, Walk. Cat. Lep. Het. B. M. xxix. p. 595. 



Gelechia patpiannu/ella, Cham. Can. Ent. iv. pp. 68,69. 



These two specimens, presented by Mr. Chambers to the P. A. 8. 

 8alem, Mass., and therefore presumably equivalent to his type, have one 

 peculiarity which is omitted in the original description. The fifth, tenth, 

 and less distinctly the thirteenth joints from the apex of the antennae are 

 whitish ochreous above, giving the appearance of three ambulations ; but 

 the difference of color is scarcely distinguishable in the under side. I 

 find this same peculiarity in Walker's Gelechia absconditella, and have 

 no hesitation, after a careful examination of his type, in referring G. 

 palpiannidella to that species. Walker's "length of wings G lines," 

 should have been "expanse of wings t! lines," which is an outside meas- 

 urement. Something approaching to the same ornamentation of the 

 antennae is described by Mr. Chambers as a characteristic of Gelechia 

 tephr late/la, Cham. (Can. Ent. iv. p. (i8), which, however, appears to 

 differ considerably from G. absconditella in general coloration. 



This specids appears to be allied to Gelechia ( Auaca nipsi>i) antht/l/i- 

 detta, Hiib. ( Wocke, Cat, 2078).

smooth, orange-yellow, the secoud joint thickened,' nut tufted, the apical joint 

 longer than tlie second. Eyes crimson (as in G. agrimoniel la, Clem.). Antennae 

 greyish fuscous, indistinctly annulated with pale ochreous. Head iridescent steel- 

 blue ; face yellow. Fore wings with the apical margin slightly more oblique than 

 in G. ugrimonieUa, greyish fuscous from the base to beyond the middle, with a 

 greenish hue in some lights ami a steel-grey streak along the costal margin, pass- 

 ing over the front of the thorax; beyond the middle very dark brown, with a 

 transverse white fascia extended outwards at the commencement of the costal 

 cilia, narrowed in the middle of the wing, and somewhat dilated about the dorsal 

 margin; beyond it are three, sometimes four, white tooth-like Streaks, with their 

 bases joined towards the apical margin and separated from the steel-grey fringes 

 by a reduplicated line of dark brown, which passesaround the apex. Hind wings 

 brown, with grey fringes, oblique, but scarcely emarginate below the apex; the 

 base of the costal margin steel-grey. Abdomen brown, with three or four white 

 transverse bands at the ends of the posterior segments. Posterior legs dark brown 

 externally, pale ochreous on their inner sides, banded with pale ochreous above the 

 spurs (which are also pale ochreous) and at the tarsal joints. Expanse II! millim.
