1880.] LEPIDOPTERA FROM FORMOSA. ()7^> 



marginal line, fringe sordid white ; secondaries silky white ; thorax 

 pale golden brown ; abdomen sordid silky white : under surface white, 

 the primaries and body tinted with golden brown. Expanse of wings 

 1 inch. 



One specimen. 



Very much like Leucaniu info-ens in colouring. 



58. Alexia formosana, sp. n. 



Primaries above pale reddish clay- colour mottled with grey, the 

 apical third of costal border and a cuneiform subapical patch on the 

 outer margin grey ; reniform spot just visible as an indistinct B- 

 shaped marking, the lower half filled with blackish scales ; an 

 angular discal series of seven black dots, the lower three forming an 

 oblique line with the inner edge of the subapical cuneiform patch : 

 secondaries opaline white with broad pale smoky-bi'own outer border, 

 veins brownish: thorax pale clay-colour: abdomen pale brown, densely 

 clothed with long white hair at the base. Under surface of the 

 wings shining opaline white, the costal and apical areas tinted with 

 brown and speckled with black : primaries with a nearly straight 

 discal series of eight black dots on the veins, the first two confluent ; 

 a marginal series of very minute black dots : secondaries with a curved 

 discal series of seven black dots on the veins, a marginal series of 

 smaller black dots between the veins : body sordid, black-speckled. 



Expanse of wings 1 inch 5 lines. 



One specimen in fair condition. 



Resembles some of the Moths associated by Walker with Leucania 

 extranea ; indeed it is possible that this genus may be represented in 

 that series. 



59. Nonagria gracilis, sp. n. 



Primaries pale golden brown, with slender darker marginal line 

 and whitish fringe ; secondaries silky white, tinted with golden brown ; 

 body pale golden brown, the thorax greyish, the abdomen whitish : 

 primaries below paler than above, the internal area white ; second- 

 aries white, the veins slightly sordid ; body below pale sandy brown. 

 Expanse of wings 10 hnes. 



One male example. 



Glottulid^?'. 



60. Chasmina glabra. 



Chasmina glabra, Walker, Cat. Lep. Het. Suppl. ii. p. G36 (18G5). 

 Two females, undistinguishable from a female in the Museum from 

 New Caledonia. 



Xylophasiid^. 



61. Spodoptera erica, sp. n. 



Primaries above sericeous fuliginous browai, markings very indis- 

 tinct ; a small blackish-edged white discoidal stigma; four or five 



^ Walker places the genus Chasmina ia this family -with liesitation ; in my 

 opinion it is more nearly allied to the Acontiicia;.
