Nordstroemia humerata (Warren) comb. n. 



(PI. 4, fig. 328; Pis. 9, 10, figs. 350, 355, 356) 



Albara humerata Warren, 1896 : 335.

This species is readily separable from the other species of Nordstroemia by the 

 small size, the weakly falcate fore wings, the distinctive colour-pattern of the wings 

 (see plate in Warren, 1922) and by the simple unbranched socii and uncus in the 

 male genitalia. The affinities of humerata within Nordstroemia are doubtful, though 

 its present generic placement is probably correct.

Nordstroemia undata sp. n. 



(PL 4, fig. 329 ; Text-figs. 161-164) 



o*. Outer surface of palp, front of head, and pectinations and base of antenna reddish brown ; 

 rest of antenna and patch posterior to base of antenna buff ; patch between antennae, posterior 

 margin of vertex and collar very pale buff. 



Thorax buff. Colour-pattern of upper surface as in PI. 4, fig. 329. Ground-colour of upper 

 surface of fore wing buff, slightly darker apically ; medial fasciae and cell-spots darker buff, 

 subterminal fascia dark brown ; outer margin edged with orange-buff ; fringe dark brown. 

 Hind wing brownish white on upper surface ; trace of postmedial and subterminal fascia at 

 anal margin in some specimens, discocellular spot of under surface usually showing through 

 wing. Under surface of fore wing buff, more brownish apically, at base and along costa ; 

 with dark brown discocellular spot, trace of spot at posterior angle of cell, and trace of anterior 

 part of postmedial fascia ; outer margin and fringe as for upper surface. Under surface of 

 hind wing pale buff irrorate with brownish buff distally and anteriorly ; usually with faintly 

 marked brownish buff postmedial fascia ; cell-spots as for fore wing. Legs pale buff with 

 outer surface of prothoracic leg darker buff. 



Abdomen brownish white. 



o* genitalia as in Text-figs. 162-164. Diaphragma with very weakly developed lateral 

 sclerites ; seventh abdominal sternum unmodified. 



$. As for male but with filiform, sparsely ciliate antennae. 



$ genitalia as in Text-fig. 161. 



Wing, o* 17-0-19-5 mm. (8) ; $ 17-5-21-0 mm. (17). 



Readily distinguished from the rest of the genus by the very distinctive colour- 

 pattern, undata has been placed in Nordstroemia because of general generic resem- 

 blances in the male and female genitalia. It is, however, clearly much less closely 

 allied to the type-species than the remaining species of Nordstroemia.
