AMERICAN TORTRICIDAE. 263 



Posterior wings dull fuscous internally, deep ochreous beyond. Under 

 surface of both pairs ochreous, deeper in color apically, where they are 

 frequently speckled with brown irrorations. 



Expanse, % 22 — 25 mil,; 9 24 — 30 millimeters. 



Habitat — Mass., N. Y., Pa., Fla., and Texas. 



Tortrix gurgitana, n. s. (Plate iv, fig. 16.) J _ 



Head and thorax tawny brown. Palpi dark brown above, paler be- 

 neath. Anterior wings boldly arched at the base of costa, which is 

 deeply excavate from the middle to just before the obtusely produced 

 apices. The upper surface is irregularly striated with brown lines and 

 all the veins distinctly covered with blackish-brown scales. Basal 

 patch indicated by a fine line of brown scales which curving outwardly 

 to below the cell, runs thence obliquely inwardly to internal margin. 

 Central fascia brown, narrow from costa to the cell where it is interrup- 

 ted; below the cell it spreads out broadly towards the internal angle. 

 This fascia is distinctly limited by two lines of brown scales. Costal 

 spot indicated by an aggregation of brown scales on the costa within 

 and below the excavation, from which two fine lines run gradually ap- 

 proaching each other to internal angle. Fringes blackish-brown api- 

 cally becoming paler towards internal angle. 



Posterior wings pale shining fuscous internally, pale ochreous beyond. 



Under surfice of both pairs pale ochreous, of a deeper shade on costa 

 and apically, where there are indications of two lines of brown scales 

 running parallel with the internal margin. 



Expanse, $ 26 — 28 mil. 

 Habitat. — West Virginia (Jas. Ridings), Illinois (J. C. Allen). 

 Pennsylvania (Theo. Bunte), 



This species is nearly allied to rosaceana, but is readily distinguished 

 from it by the excavate costa of the primaries and the distinctness 

 with which the veins are marked by lines of dark scales. 



Tortrix purpurana. (Plate 1, fig. 4.) 



Lozotaenia purpurana, Clemens, Proc. Ent. Soc. Phil., v, p. 136, 1865. 



Palpi, head and thorax dark brown. Anterior wings with the usual 

 markings nearly obsolete. In some specimens the basal patch is indi- 

 cated by an indistinct curved line of glossy dark brown scales, and the 

 central fascia by two similar, nearly parallel lines partly filled in with 

 scales of a warmer hue. The excised portion of the wing before the 

 apex is bordered with bright brown scales from which two lines run 

 parallel with external margin to internal angle. Fringes concolorous. 



Posterior wings dark fuscous internally, pale testaceous beyond.
