184 Mr. L. B. Piout on 



type taken in 1915, tlie other two labelled "dry season^' 

 but not dated. 



Perhaps a race of hypopolia, Hmpsn. (Nov. Zool. xxv. 

 p. 208), from British Central Africa. Fore wing with ante- 

 median line more upright, postmedian'more deeply bisiuuate, 

 aud with violet shade in median area ; hind wing with 

 white apical spot. 



27. Achaa indistincta, Walk. 



This species, of which the type is in coll. Joicey, has been 

 sunk by Hampson (Cat. Lep. Phal. xii. p. 538) to ablunaris, 

 Guen. On account of the broader dark border of the hind 

 wing (two-fifths of length of wing, against two-sevenths in 

 ablunaris), combined with more angulated postmedian line 

 on underside of both wings, it seems likely that it is really 

 a separate species. 



Costa Rica to Bogota. 



28. Parallelia valga, sp. n. 



? . — 58 mm. 



Head and body coloured as in riyidistria, Guen. ; palpus 

 with third joint considerably shorter than in the ? of that 

 species, less than one-third as long as second joint. 



Fore wing coloured as in the lighter forms of rigidistria ; 

 subbasal line as in that species ; autemedian arising some- 

 what further from base, strongly incurved between SC aud 

 base of M^, strongly oblique outwards to hind margin near 

 median line ; median line slightly interrupted outward near 

 costa ; postmedian line much less deeply crenulate than in 

 rigidistria, with a single angle at W ; indications of a dark 

 line from this angle to apex ; subtermiual further from 

 terraen, the dark shading beyond it rather weak ; fringe 

 light brown. 



Hind icing with termen rather fuller near tornus than in 

 rigidistria ; less clouded with blackish ; pale postmedian line 

 wanting ; tornal pale mark weak. 



Underside rather paler than in most rigidistria ; fore wing 

 with the median line obsolete, postmedian extremely weak, 

 arising further from termen than in rigidistria, apparently 

 deeply incurved so as to reach postmedian angle of cell; 

 hind wing with cell-dot replaced by a weak comma, median 

 and postmedian lines approximated, especially posteriorly, 

 the latter scarcely crenulate, subterminal chiefly shown by 

 three or four weak yellowish spots in anterior part. 

 Khasia Hills {Nissary).
