AMERICAN LEPIDOPTERA. 101 



Hypena citata, Grote. — 9- — ® nr smallest species with a casual resem- 

 blance to the European H. antiqualis, but more nearly allied to the succeeding 

 species. Apices of primaries determinate, external margin roundedly exserted 

 at extremity of median nervules; fringes rather long, cut at extremity of 

 the veins. Blackish, washed with whitish, indistinctly marked, somewhat 

 speckled. At base downward along internal margin obliquely to t. p. line the 

 forewings are pale, dull brownish ; orbicular a black scale dot. T. p. line dis- 

 tinctive, nearly perpendicular, continued, outwardly a little irregularly waved, 

 whitish with an inner olivaceous brownish marginal line. Rsniform annulate 

 with pale center touching the t. p. line at extremity of disc. A very indistinct 

 minutely dentate arcuate subterminal line. A diffuse oblique whitish apical 

 6hade; costal anteapical white marks. Terminal line black, broken on the 

 veins, interspaceal, preceded by a coincident white line. Kervules tending to 

 be marked by white scales. Hind wings blackish, concolorous, dark; fringes 

 interrupted with a paler shade. Beneath both wings like secondaries above. 

 Body parts pale beneath, dark above ; labial palpi with the second thickly 

 scaled joint elongated. Expanse, 19 m. in. 



Habitat. — Alabama; August. 



A similar inception of the t. p. line on costa may be traced in H. 

 evanidalis and H. humuli, but the line is continuous and everywhere 

 distinct in H. citata. 



Hypena evanidalis, Robinson.— % 9 . — I think that the " lighter rusty- 

 brown " specimens mentioned by Harris in his description of H. humuli, refer 

 to this form which may, indeed, not be specifically distinct from the following, 

 than which it seems a little smaller. Light dusty ruddy brownish with a 

 more or less evident apical blackish shade. A dull blackish costal patch 

 above the discal cell ; on this are two separate pairs of superposed raised scale 

 dots. An angulated pale line at extremity of cell. A subterminal series of 

 small dots opposite terminal interspaceal black points. Hind wings rather 

 pale with paler fringes. Labial palpi elongated. Expanse, 28 to 30 m. m. 



Habitat. — Eastern and Middle States. 



Resembles the European Hypena rostralis, but differs by the more 

 even, less sinuate external margins of the wing 



Hypena liumuli, Harris. — % 9 • — Darker and larger than the foregoing, 

 I think Harris' " dusky or blackish brown " specimens are to be referred here. 

 The fore wings are marbled and obscurely colored. The ornamentation is seen 

 with difficulty, but it consists of raised scale dots and the angulated extra dis- 

 cal line as in H. evanidalis, from which it may not be distinct. Harris' figure 

 in the "Insects Injurious to Vegetation " undoubtedly represents this form 

 and not the preceding. On the whole this species rather resembles the Euro- 

 pean H. obsitalis, though narrower winged and darker, and, with H. evani- 

 dalis, quite unlike H. rostralis in the shape of the wings. Expanse, 30 m. m. 



Habitat. — Throughout the Atlantic District; I have a specimen 

 from Alabama.
