Head full in front, as long as broad ; male antennae plumose; palpi very 

 slender, acute, extending a little beyond the front of the head. Fore wings 

 with the costa more convex than usual, the apex either somewhat rectangular 

 or somewhat produced; outer edge slightly bent, less oblique than in Cyma- 

 tophora. The hind wings do not reach beyond the tip of the abdomen: they 

 are rounded, entire, sometimes a little produced toward the apex. In the 

 venation, this genus is intermediate between the genuine Boarmince and the 

 Ennomince. The costal vein anastomoses with the subcostal. There are 

 six subcostal venules ; a rhomboidal, short, subcostal cell, sometimes a second 

 one beyond (in the specimen figured on plate 6, fig. 3, it is represented as 

 open). The wings are thin, seinihyaline, and whitish, with two irregularly- 

 scalloped dark lines on the fore wings, and one extradiscal scalloped line on 

 the hind wings. The discal dots are very distinct. Hind male legs long 

 and very slender, the tibiae not being swollen ; the tarsi are one-fourth 

 shorter than the tibiae. Abdomen long and slender. Curtis's genus Chora 

 is really synonymous with Cymatophora {Boarmia). The type being Cyma- 

 tophora {Boarmia) cinctaria, there is no good reason why it should be retained, 

 though I do so, following customary usage. 



Larva. — "Caterpillars of medium length, rough, color of lichens, flat- 

 tened beneath, with all the rings ornamented with conical tubercles; head 

 small, globular; living on the lichens of trees.''— Guene'e. 



Pupa rather long, with broad, longitudinal, brown bands. Guene'e states 

 that it is placed under bark or under moss in a light net-work of threads. 



The species are easily recognized by the unusually transparent wings, 

 their whitish color, and the dark scalloped line and distinct discal dot, and 

 resemble the species of Zerene. 



Synopsis of the Species.
