iihan in Melasiua, and the wings are shorter and broader in 

 the former. In the species stibarodes the build is very 

 annch like (1. i mi tat a and the bag is ahnost identical in 

 method of building, and, as Meyrick remarked in his paper on 

 this species, more like one of a Psychid moth than of a 

 Tineid. The palpi of stibarodes are covered entirely with 

 hairs which are spreading, like in the typical G-ymnelema. 

 In Melasina all the palpi I have seen are mainly covered 

 Avith scales which lie close together, though sometimes they 

 have some hairs mixed with the scales, and then also a tendency 

 to spreading and to reduction of length of palpus; never, 

 however, to the extent found in (ly mnelema. The neura- 

 tion gives little help, but that 7 and 8 of fore wing are gene- 

 rally stalked, however shortly, points to Glymnelema and 

 not to Melasina; in the female cotype of stibarodes this 

 stalk is as long as we find in Trichocossus arvensis. The 

 lack of consistency in the running of these veins in stibarodes 

 is also found in G. imitata, to which, I think, stibarodes 

 is mostly allied.
