77. Gadirtha impingens ? 



Gadirtha impingens. Walker, Cat. Lep. Het. xiii. p. 1103(1857). 

 One specimen, apparently referable to this species, but larger than 

 the type, and too much rubbed for certain identification. 



78. Ercheia CHARON, sp. u. 



Near to E. cyllaria\ but tlie primaries above witli no distinct 

 oblique costal whitish dash, the discal parallel black lines forming a 

 wide semicircular curve; a submarginal irregularly undulated whitish 

 line : secondaries with the central white spot large, the discal spot 

 obsolete, the apical spot large and oblong. Secondaries below with 

 no distinct black patch on the anal area, but the discal belt conti- 

 nuous ; two distinct zigzag submarginal pale brov/n lines. Expanse 

 of wings 2 inches 5 lines. 



One female example. 



I have compared this with a specimen of JE. cyllaria in Mr. Moore's 

 collection, and find it very distinct; it is larger than that specimen. 



Catephiid.^, 

 79- Ercheia htsifera. 



AchcEafusifera,\i&\\\e\-, Cat. Lep. Het. xiv. p. 139S (1857). 



One example. 



The following species, placed in AcJicea by Walker, must be referred 

 to Ercheia — A. cjiUota, A. cyllaria, A. fusifera, A. signivitta, and 

 A. polycliroma ; CaiepJda dubia may also be placed in this genus.

80. Plecoptera dolosa, sp. n. 



Greyish brown, more cinereous in the female than in the male :

 with grey centre and brown margin, followed in the male b}' a 

 notched dark-brown sjiot ; discal line extremely irregular, having 

 two deep angular sinuses ; submarginal line indistinct, zigzag,

 which become gradually more defined towards the costal margin; in 

 the same sex there is an indistinct marginal series of greyish spots : 

 secondaries crossed in the middle by an oblique, slightly sinuous, 

 whitish-bordered, blackisli stripe ; external area dark brown, crossed 

 by an abbreviated whitisli ziczag line, and interrupted by a marginal 

 series of pale spots. Under surface altogether paler ; wings with
