Pyrophila glabella, Morr. 



Havilah, Cal. {Mr. Henry Udioards, No. 6589). The specimen does 

 not dififer essentially from one sent me from Illinois by Mr. Thomas B. 

 Bean. 



ZOTHECA TRANQUILLA Var. VIRIDULA. 



I have received two specimens of tranquilla from California, which, 

 instead of being pale reddish-brown over the thorax and primaries, are 

 pale green, and to this color- variety, which is sufficiently extraordinary, 

 I give the above name. The simple markings of the typical form are 

 evident, but at first sight no one would refer the two to the same species* 



Graphiphora contrahens, n. sp. 



$. — Form slight. Byes hairy. Tibiae unarmed. Thorax hairy, 

 untufted. Fuscous over faded ochreous. The primaries are darker- 

 shaded over the costal region, above the middle of the wing, to the 

 reniformj again over terminal and subterminal spaces at the middle 

 and on costa, where three pale dots are included. Lines geminate. A 

 dark basal mark. T. a. line waved, upright. Orbicular obsolete. Eeni- 

 form rather small, rounded, concolorous with the pale ochre tint of the 

 wing, which extends beyoud it to apices. T. p. line slightly sinuate, 

 contiguous to reuiform. A black, interrupted, terminal line. A pale 

 line at base of fringe. Hind wings dirty white, with dark, interrupted, 

 terminal line. Beneath whitish ; fore wings shaded with fuscous on the 

 disk, with a common, dark, slightly irregular line and <. 'seal points. 

 Thorax mixed grayish. Expansion^ 38 millimetres. Nova Scotia (No. 

 2378, Mr. Thaxter). 



I have seen a specimen of this species, labelled "Celwna-contraJiena 

 Walker", in Coll. Can. But. Soc. 



LlTHOPHANB VIRIDIPALLENS, Grote. 



$. — Pale gray-green; lines on primaries darker-shaded. Allied to 

 querquera, but differing at once by the absence of the black markings 

 and the narrower reniform. Thorax with a central black dot ; edges of 

 the tegulsB faintly lined. Lines on primaries double ; median shade fus- 

 cous or blackish, upright, diffuse, dentate. Subterminal line without 

 the black markings of querquera at the middle, and again on submedian 

 fold. Terminal dots reduced. Hind wings fuscous, with whitish fringes, 

 not ruddy as in querquera; beneath with a faint flush. Size of querquera. 

 Massachusetts {Mr. Boland Thaxter). 



LiTHOPHANE CAPAX, G. & B. 



This species has the tibise unarmed. Notwithstanding its broader 

 wings, it must be referred to LitJwphane ; it is not congeneric with 

 Anytus sculptus Grote, which has spiuose tibioe.
