costal margin, and is thus scalene. In T. camerounensis the apical side is 

 angled acutely to the costal margin, the triangle being equilateral. The 

 contrast in color between this triangle and the basal area is greater than in 

 T. rattrayi, the triangle being of a darker brown and the ground tone of the 

 wing lighter. In T. rattrayi there are two bands, one subbasal, one median, 

 both curving basad as they approach the costal and the inner margin. In 

 T. camerounensis the areas included in these two bands are faintly indi- 

 cated by interrupted geminate lines. The narrow white line bordering the 

 costal marginal triangle in T. rattrayi apically, is in this form a brighter 

 white, and broadens costally. A dark line extends from a point on the 

 costal margin, 4 mm. distant from the wing tip, and at right angles to it, 

 to SC5; thence it extends basad to a point between Rl and R2, where it 

 curves distad to R2; thence first basad and then distad to R3, where it 

 merges into the dark line which this form has in common with T. rattrayi. 



Fore wing beneath : Otherwise like T. rattrayi, it has on the costal mar- 

 gin, 5.5 and 4 mm. distant from the wing tip, two bright white dote, one 

 mm. in diameter, which are only obscurely indicated in T. rattrayi. 



Hind wing above: Dark brown, unicolorous except for a light brown 

 area at anal angle, crossed by a narrow, dark submarginal line. 



Hind wing beneath: Like T. rattrayi, except for a pink line extending 

 from base to apex near anal angle. 



Temnora rattrayi R. and J. 



Al. ant. long., 9,19 mm. Al. ant. lat., 9,8 mm. Marg. ext., 9,10 mm. 



Habitat. — Banga Manteke, Belgian Congo. One female in coll. B. 

 Preston Clark, collected by Mr. A. L. Bain, and received in exchange from 

 Dr. W. J. Holland of the Carnegie Museum. The female of this species, 

 so far as I know, has not been previously noted. 



The female of this rare species, at least in this instance, follows 

 the pattern of the male, but the markings are more indistinct. 



Gurelca mulleri sp. nov. 



Al. ant. long., d\ 21 mm. Al. ant. lat., cf , 7 mm. Marg. ext., o\ 8 mm. 



Habitat. — Guerrero, Mexico. One male in coll. B. Preston Clark, pre- 

 sented by my friend Mr. Roberto Muller, of Mexico City, for whom I 

 have named it.
