AMERirAN LEPIDOPTERA. 859 



Abdomen griseous. crested towards the base ; beneatli. paler, with two 

 fine lateral dark lines. Legs pale testaceous griseous; tarsi subannulate. 



Anterior wings of an intense bright green above. Ordinary lines 

 prominent and distinct, carneous with black edges. A basal half-line. 

 Transverse anterior line nearly straight, regularly and shortly jagged 

 or dentate. JNIedian space wide. Orbicular and reniform spots dis- 

 tinct; the former carneous with a prominent black central dot and a 

 fine black annulus; the latter, largely carneous, rounded, faintly mar- 

 gined and shaded outwardly with whitish. There is an accessory spot 

 below the median nervure underneath the orbicular and smaller, while 

 similarly appearing to this latter, wanting, however, the carneous color. 

 There is a diffuse, discally interrupted, dark median shade Jine strongly 

 marked on costal region, which latter shows also a second dark shade 

 line. Transverse posterior line arcuated strongly over the nervules, 

 but running very slightly inwardly obliquely below median nervure, 

 thus leaving the median space wide inferiorly. This line is followed 

 by the narrow, but very distinct, pure white subterminal space; the 

 white color gives place superiorly to the green ground color of the wing. 

 Subterminal line black, consisting of a series of interrupted cuneiform 

 marks, irregular below costa. Three white costo-apical streaks. Ter- 

 minal space bright green ; a terminal series of dark interspaceal marks. 

 Fringes dark griseous, narrowly cut with paler hairs at the extremity 

 of the nervules. Secondaries evenly dark griseous, silky, with no per- 

 ceptible markings; fringes a little paler than the wing. Beneath, both 

 wings are obscure greyish ; secondaries with a darker shaded trans- 

 verse line and discal dot; primaries with costal marks and dots, the 

 fringes plainly cut with pale shades.

Habitat. — Atlantic District. (New York to Penna. !) 



This pretty species is a miniature reproduction of E. muscosula, (rn.. 

 and is readily separated from the latter by its smaller size, the brighter 

 green of the primaries, the carneous color of its transverse lines and 

 ordinary spots, and quite prominently by the absence of the white sub- 

 terminal line which is characteristic of Guenee's species. 

 Selenia kentaria, G. & R., Deso. Am. Lep. i^o. 1, pp. 12 — 13, figs. 5 — 6. 



This species, which is a true Selenia, is mentioned to correct an er- 

 ror which accompanied its original description. It is closely allied to 

 the European S. illunaria, with which it is compared and the specific 

 differences pointed out, but owing to an error in the determination of 

 our material of the European species, this latter is alluded to as "•Peri- 

 callia si/riiu/a7-('a,'' which in reality is a distinct though allied form.
