on the submedian nervure. The orbicular spot is nearly obsolete, 

 sometimes seen as a blackish spot. Reniform spot narrow and sub- 

 rectangular, filled with black. The median shade is blackish, dif- 

 fused, passing obliquely from the costa across the reniform, then 

 parallel with the exterior line. The latter is drawn in below the cell; 

 its teeth connect with a series of more or less distinct spots on the 

 nervules. The subterminal line is light, preceded by a dark, diffuse 

 shade; in one specimen this shade is condensed into a series of black 

 spots. The nervules towards their termination are sometimes marked 

 with black. A yellow line at the base of the concolorous fringe. The 

 posterior wings are white at the base, with a diffused, gray, terminal 

 border. The fringe is yellow. Beneath the anterior are gray; on 

 the costa the exterior line is seen. The posteriors are whitish, 

 evenly sprinkled with gray atoms, with a distinct discal dot and 

 traces of the median line. The base of the fringe yellow.

Described from three specimens which vary among themselves, but 

 which are evidently referable to the same type. 



Homohadena retroversa nov. sp. 



This form differs very much from the typical badistriga Grote, and 

 with my present material I can hardly doubt that it is specifically 

 distinct. 



Size and coloration of H. badistriga, but both wings are narrower, 

 and the posterior more angular and less rounded. The basal 

 streak is obsolete. The median lines have their origin in irregular 

 spots on the costa. The interior line is only slightly curved, and not 

 strongly outwardly projected on the costa. The ordinary spots are 

 visible, small, black-centred, with broad white annuli. The broad 

 streak found in badistriga extending from the interior line to the ex- 

 terior margin, is here reduced to a fine black line, present only just 

 before and after the exterior line. The latter is not evenly outwardly 

 projected beyond the reniform spot, but follows its outlines closely, be- 

 ing slightly depressed immediately after it, strongly drawn in below it, 

 and then connected with the interior line by a short, intense black 

 streak ; below this dash the line extends obliquely outwards, not 

 straight to the inner margin, as in the allied species. The black 

 dashes on the nervules in the terminal space are obsolete in retro- 

 versa. The posterior wings are as in badistriga, except that the 

 median line is absent. The posterior wings, beneath, have the
