 middle of thorax above, and a band from the apical third 

 of the costa to the middle of the hind margin, bright

 yellow. Hind wings and abdomen white.

 Catharylla rufisignella Zell., Beitr., p. 96 (1872). 

 Argyria pontiella Zell., Exotic Micr., p. 59 (1877). 



Expanse of wings, 12-16 mm. Top of palpi, face, thorax 

 and fore wings pure white, with a satin lustre ; sides of palpi, 

 top of head, collar, a dot on the middle of the costa, one on 

 the middle of the hind margin and a more or less complete 

 line connecting them, a preapical costal triangle divided by 

 an oblique of the ground color and the terminal line, all dark 

 rust red. Fringe rust yellow. Hind wings white, with a 

 silken lustre. In one variety (Plate V., fig. 5) the median 

 stripe of the fore wing is so far obliterated as to have only 

 the costal, marginal and cellular spots, and in the typical 

 rufisignella the cellular spot is also obliterated (Plate V., 

 fig. 4). Fig. 6 represents a typical pusillalis^ of which 

 lusella and pontiella are synonyms. I have before me a 

 long series passing by insensible grades from rufisignella 

 into lacteella.
