large and is placed in the angle of the midrib, and a lateral vein. 

 The web is so thin that larva is visible through it ; and yet is so com- 

 pact, that I at first mistook it for the loosened epidermis, and believed 

 it to be a mine. When the larva is ready to pupate, it gathei-s the 

 whole web into a dense mass around it, in the angle of the veins, and 

 passes the pupa state under it. I have only found it in September 

 and October, and the moth emerges in April. 



Semele — gen. nor. 



This genus is allied, but not very closely, to Thiea. In repose the 

 species sit very flat upon the surface on which it rests, with the wings 

 nearly horizontal but a little depressed. The tongue is rather short 

 and is naked. Maxillary palpi well developed, pendant ; labial palpi 

 divergent, ascending as high as the vertex, with the second joint a 

 little longer and not much thicker than the third, and clothed with 

 scattered depressed bristles ; head roughened as in Tinea nearly ; An- 

 tennae slender simple about §• as long as the forewings. \Yings long 

 rather narrow (having but a single specimen I have not denuded 

 them), the cell of the forewings is closed and they are numerous mar- 

 ginal veins ; the cell of the hind wings appears to be unclosed and 

 they have long cilife and are narrow, with the costal margin excised 

 from about the middle and the posterior margin curved like a knife 

 blade. 



S. cridatella, n. sp. 



Maxillary palpi yellowish white ; labial palpi with the second joint 

 dark brown with a white line along its upper surfiice ; third joint 

 white. Face white, vertex black, antennae brown, and the upper sur- 

 face of the thorax deep velvety black. Fourwings shining velvety 

 black with a large spot like burnished silver at the base and not quite 

 touching the costa, margined behind by a transverse row of raised 

 scales ; about the basal fourth is a shining silvery fascia which is 

 slightly curved, a little irregular in outline, widest about the middle 

 but wider on the costal than on the dorsal margin, and margined be- 

 hind by a transverse row of raised scales. About the middle of the 

 wing is another fascia of the same hue, which is a little oblique, being 

 nearer the base on the costal than on the dorsal margin, and appear- 

 ing under the lens to be slightly interrupted cibout the middle ; it also 

 is irregular in outline, and margined behind with a transverse tuft 

 near the costa, and has some scattered silvery scales margining it behind 

 from the middle to the dorsal margin, and extending back along the
