Head smooth, the forehead obtuse. Antenna; setaceous, almost as 

 long as the body, the basal joint sJiort, clavate. Labial palpi small, 

 rat/ier thick, acuminate. Tongue of moderate length. Abdomen rather 

 thick, short. Wings with very long cilia, the anterior elongate, with 

 metallic spots, the posterior linear-lanceolate. In the anterior wings 

 the discoidal cell is expanded posteriorhj, and hardly closed ; there is 

 no secondary cell ; the furcate apical vein terminates in the apex and 

 in the hinder margin, below it are four veins; the subdorsal is simple ; 

 the submcdian not thickened ; in the posterior wings the median vein 

 is trifid, tlu; discoidal vein is simple, and the apical vein is simple. 



This genus only contains a single species, of which no speci- 

 mens have been taken in this country for probably the last thirty 

 years. According to tlie observations of Tischer and lleegerj the 

 larvse feed in June, rather gregariously, on Chenopodm^ii, Atri- 

 plex, etc, drawing several leaves togctlier by a number of silken 

 threads ; the perfect insect appears in J uly, and is frequently again 

 met with in May after hybernation. 



It is hardly necessary to add that tlie Linncan habitat, "in 

 Mali foliis subcutanca," is founded on a misconception that Dc 

 (icer^s figure of a Jjit/ioculletis, to which he refers, rt'presents this 

 insect; subseciuent authors have copied Liinm:us in indicating 

 apple as the food of the larva, without verifying his observation, 

 or noticing the evident cause of his error.
