nations decreasing to tlie apex ; ciliated beneath in the females: head small; 

 forehead smooth: et/es small: thorax moderate; wings entire, the hinder 

 margin rounded, anterior somewhat elongate, posterior ovate triangular : 

 body slender in the males, with a tuft at the apex ; stouter in the females, 

 and furnished with a retractile tube at the apex: legs moderate, slender; 

 posterior tibia; with two i)air of spurs. Larva with sixteen legs, slender : 

 pupa inclosed in a silken cocoon, covered with extraneous substances. 



The long, porrected, palpi of the Aglossae, the terminal joint of 

 which is considerably exposed, taken in combination with the varied 

 or tabled appearance of the wings, distinguish them from the pre- 

 ceding genera; their hirvae subsist upon butter, grease, and oleaginous 

 substances, and the perfect insects frequent houses.

Wings cinereous ; anterior glossy dusky-ash, with a short fuscous line at the 

 base, two nearly contiguous very much flexuous ones before the middle, the 

 space between which is pale ashy-ochre ; and midway between this and 

 the posterior margin is a third waved dusky streak, bordered exteriorly with 

 ochreous-ash ; the space between the two last streaks is rather darker and 

 bears a dusky dot, edged outwardly with ochreous-ash ; and the costa 

 between is sometimes of the latter tint : on the hinder margins arc some 

 obscure ashy clouds : posterior wings fuscous, with some very obsolete 

 darker markings : cilia fuscous. 



In some examples the markings are much stronger, and the contrasts of colour 

 more evident; the insect varies considerably in size. 



Caterpillars didl brown, shining; it feeds on butter, lard, and other oleaginous 

 substances : the imago appears towards the end of July.
