antennse are simple, scaled. Eyes naked; ocelli wanting. Maxillae 

 not perceivable. Labial palpi slight, hairy, ascending, curved. Body 

 slender, sparsely haired. Legs rather stout and long ; hind tibiae with 

 two pairs of spurs. Fore wings elongate ; costa arched 5 external mar- 

 gin oblique, even ; internal margin rounded at base, retiring before in- 

 ternal angle. Veins 12, simple, cell divided ; veins 2, 3, 4, equidistant 

 from the end of median vein. Vein 1 furcate at base. Cell incompletely 

 closed. Veins 5 and 6 nearly equidistant between 4 and 7 ; 7 from ex- 

 tremity of the vein dividing the cell ; 8, 9, 10 near together from upper 

 corner of cell, running to costa before apex ; 11 out of subcostal vein 

 very near the base ; 12 free. Hind wings 8- veined ; veins simple ; the 

 cell incompletely closed ; vem 2 out of median vein at within outer third; 

 veins tending to be equidistant. The fore wings are ochrey brown, 

 with costal dots noticeable before apices. A pale ochrey shade on in- 

 ternal margin at base, extending upwardly in a triangular manner be- 

 yond the middle. This shading is not always defined. A curved discal 

 streak. Hind wings brownish fuscous. Fringes on both wings a little 

 darker ; even, concolorous. Beneath much as above ; costal region of 

 secondaries ochrey brown. The hairy body parts concolorous fuscous 

 brown ; with paler hairs about the head and face. Expanse, 30 mil. 

 JSah. — Kew York. I have not seen the male. This form has a curious 

 resemblance to Hepialus^ but the antennse are longer. 



Heterocampa Chapmanii n. s. 



'2 . Several fresh specimens of a fine species of Heterocampa are con- 

 tained in Mr. Thaxter's collection, found in Florida. The thorax and 

 fore wings are pale gray green ; the thorax behind is brown. The sub- 

 basal field is shaded with bright brown ; the curved discal streak and 

 the thick subterminal line are dark brown ; the subterminal field is 

 shaded with lighter brown. These brown or ferruginous shadings con- 

 trast. A fine brown line broken by the veins before the margin. The 

 median lines are in triplicate, of a darker gray than the wing, waved. 

 A broad white arcuate shade before the subterminal line, opposite the 

 cell, extending to costa. Hind wings gray with a mesial line, the anal 

 angle white. Beneath gray with a rusty subterminal straight shade 

 line on fore wings. This fine species expands 52 mil., and is named for 

 Dr. A. W. Chapman of Florida. It is readily distinguished from any of 

 our species, and from the diagnoses must be difierent from those men- 

 tioned by Harris in his CorresiJondence edited by Mr. Scudder. 

 Platycerura furciUa Pack. 



The larva, discovered by Mr. Thaxter, resembles that of Gharadra or 

 JDiplithera^ and is not at all like Gerura. The moth is related to Audela 

 xiGronyctoides Walk., which I have referred to the Noctuidae and not to 

 the Bomhycidae. 



Agrotis quarta n. s. 



? . Fore tibiae unarmed. Eosy brown, resembling haja. Lines brown, 

 badly marked ; t. p. line broken into dots. Subterminal line subcontinu-
