less fused, and M, more or less completely preserved. It may be 

 recognized as an Ennomid by its spined abdomen. 



6. Dominantly South American. Sparta from Europe is closely 

 related, but has rudimentary tongue and palpi and even more reduced 

 hind wings, 



7. The typical group from Europe is extremely close to Lobo- 

 phora, differing from our Umitata group only in the separation of Sc 

 and R in the male. Veritata Pears, is aberrant in its squarer, more 

 thinly scaled wings. The genus is also in South America. 



A considerable group of exotic genera will run out here. Mysti- 

 coptcra Meyr. has four spurs and a large folded lobe in the male. In 

 Siona (Schisostege) the modification on the inner margin is a small 

 pocket, as in Carsia to which it is related. The Rhopalodes group, of 

 South America, have antennae distinctly, though slightly, swollen to- 

 ward the tip ; Rhopalodes is otherwise like Trichopteryx; Tomopteryx 

 has an acute fore wing with the outer margin bent at the middle, etc., 

 an outlier is Tatosoma of Australasia, which has the same antennae, 

 a very long abdomen, the lobe spirally coiled, and in the species seen, 

 three spurs on the hind tibia. Rcmodcs has more complex structures 

 on the hind wing, and the rare combination of very long palpi and 

 smooth front. For other genera see the " Moths of India." 



8. Nannia morensata Hulst appears to be H. (Lygranoa) fusca of 

 Japan with incorrect locality, but as the type is a female I cannot be 

 sure, it could be a suffused specimen of refusata. 



Male antennae bipunctinate, head and wing characters intermediate (group 

 Lygranoa) fusca (Asia). 



Male antennae fasciculate. 



Hind wing with inner margin bent over at base only, forming a rudi- 

 mentary pocket suggesting Carsia, with a hyaline patch farther out, 

 crossed by the root of Cuj, and enclosed by the rudimentary root of Cu^; 

 Cui turning at right angles and running to anal angle. Fringe of hair 

 below M, slight beyond cell ; M^ and M^ close together at origin. 



Female with front as wide as eyes (group Nannia) refusata. 



Hind wing with a folded lobe at anal angle also, supported by the distinct 

 rudiment of Ciu, which runs to anal angle as well as Cui, — the area 

 crossed by Cuj recognizable, but hyaline only in badly rubbed material. 

 Ml and M, widely separate, female with larger eyes (group Hetero- 

 phleps) triguttata. 



Other types of structure doubtless occur in Asia where the genus 

 is better known as Dysethia.
