either shortly connected with C (1 J , 1 ? ) or anastomosing 

 (1 ? ) and may either be free from SC 3 " 4 or connected there- 

 with ; in the hind wing SC^R 1 may be either stalked (the 

 type ? ) or connate (one £ ) or even coincident throughout 

 (the only known <?). 



Microxydia riificomma, sp. n. 



cJ . 21-24 mm. — Face and vertex white. Palpus and 

 antenna ochreous, occiput and collar bright ferruginous; 

 front of thorax bright ochreous; the rest of thorax and the 

 abdomen cream-colour, base of the latter marked dorsally 

 with pale ochreous, followed by a large spot of bright ferru- 

 ginous, and this again by some much smaller ferruginous 

 marking. Fore wing cream-colour, finely irrorated with 

 ochreous, and with a few scattered dark scales ; costa, termen, 

 and fringe bright deep ferruginous, a thick, blackish line at 

 base of fringe ; the lines ochreous, rather thick, but indis- 

 tinct, at about one third and two thirds; autemedian starting 

 from a ferruginous mark from costa, somewhat bent in cell ; 

 postmedian from a thick, comma-shaped, ferruginous mark 

 at costa, which contains a smaller blackish comma, an angle 

 on R 1 at which the ferruginous mark abruptly terminates, but 

 there is a smaller one on the line at inner margin ; cell-spot 

 elongate, pale ochreous. Hind wing without ferruginous 

 costa or costal markings, otherwise the postmedian line and 

 termen as in fore wing ; antemedian wanting ; cell-spot 

 weak. Underside similar, cell more clouded with ochreous, 

 cell spots distinct, dull ferruginous, lines on fore wing 

 obsolescent, that of hind wing spotted with ferruginous on 

 the veins.

Microxydia strigosa adoxa, subsp. n. 



$ . 21-23 mm. — Differs from the typical (Peruvian) race 

 of M. strigosa, Warr. Nov. Zool. xi. p. 576, in being paler, 

 the ochreous speckling much less, and in having the post- 

 median line of both wings further from the termen, that of 

 the fore wing therefore more approximated to the antemedian;
