and toward the tip, brown ; and in the latter part much sprinkled with whitish. 

 On the middle of the costa is a short, yellowish white streak, and in the 

 apical third of the wing is an oblique line of the same hue, meeting in the 

 middle of the wing another of the same hue from the inner margin. At and 

 beneath the tip is a blackish brown spot, and in the cilia a dark fuscous line. 

 Hind wings dark ochreous, cilia the same. 



Depressaria Haworth. 



D. Lecontella. Head and face ochreous. Labial palpi ochreous: 

 second joint varied, externally with fuscous ; third joint with a slight fuscous 

 ring at the base, and one near the tip. Antenna? fuscous. Thorax ochreous, 

 with two blackish brown dots before. Fore wings dark ochreous, with dis- 

 persed blackish brown dots throughout the wing, two of which, about the 

 middle of the median nervure, are more conspicuous than the others ; 

 cilia rather pale ochreous. Hind wings pale grayish-ochreous, cilia the same. 



This is the only true Depressaria I have found thus far ; but we have other 

 nearly allied species, which differ from it in the structure of the labial palpi. 

 In this respect they resemble somewhat Gelechia r u f e s c e n s of Europe, but 

 differ from the genus to which it belongs in several particulars. I think 

 they must form a group intermediate between Depressaria and Gelechia. 



I have now nearly worked up my collection of Tineina, and would beg those 

 who feel interested in the continuation of these studies, to aid me in extending 

 my knowledge of species, by contributing collections from their various neigh- 

 borhoods. 



Description of a new species of Marginella. 

 BY JOHN H. REDFIELD. 

 Marginella roscida Redf. 



T. rhombico-ovata, polita, cinereo-lutescente, albido guttulata, versus 

 apicem albido-lineata ; labis albo, crasso, reflexo, extus fulvo trimaculato, 

 intus subdenticulato ; spira modica ; anfractus quatuor exhibente ; anfractu 

 ultimo angulato, juxta aperturam calloso ; columella quadriplicate. 



Shell rhombic-ovate, polished, light grayish brown, minutely necked with 

 white ; towards and upon the spire the white spots tend to be confluent in 

 longitudinal lines. Lip white, well thickened, obtusely reflected, extending a 

 little upon the penultimate whorl, slightly denticulate within, and bearing 

 three brown spots, one at its junction with the spire, a second about midway, 

 and the third near the base. Spire moderate, apex slightly colored, with 

 about four whorls visible ; the last whorl is distinctly shouldered, a little be- 

 neath the suture and near the aperture shows a vitreous deposit. Columella 

 with four plaits ; upper ones somewhat oblique, lower ones more so. Aper- 

 ture yellowish brown within. Length 0*57 in. (14 millim.) ; breadth 0*32 in. 

 (8 millim.) 



Habitat. Coast of South Carolina. 



Remarks. The general form of this shell is nearly that of M. apicina Menke, 

 and the spots upon the outer lip give it a further likeness to some varieties of 

 that species, but the spire is more developed, and the last whorl more dis- 

 tinctly angular than is usual in M. apicina, while the latter never displays 

 the minute white flecking of the species under consideration. This last feature 

 is common also to M. guttata, M. nivosa and M. pruinosa, but all these are 

 quite different in form and in development of spire.
