umber-brown at the sides and beneath. Thorax ochreous above, 

 brown at the sides, the tegulae shining grey. Fore wings with 

 the costa very slightly raised in the middle, apex pointed, apical 

 margin oblique, not convex : silvery grey, with four narrow trans- 

 verse fasciae, each golden yellow, with an umber-brown central 

 line throughout ; the first commencing at one-third from the base, 

 slender, outwardly convex ; the second central, stouter, slightly 

 convex outwardly, and differing from the others in the more im- 

 portant umber-brown line nearly covering its outer half; the third 

 at about two-thirds of the wing-length, slightly oblique, tending 

 outwards from costal to dorsal margin, where it terminates just 

 before the anal angle ; the fourth, also oblique, terminating beyond 

 the anal angle ; beyond these fasciae is a short transverse streak of 

 a similar colouring, immediately before the apex, preceded by a 

 short costal streak of the same colour ; a diffused golden yellow 

 basal-streak above the middle does not reach the first fascia ; cilia 

 greyish fuscous. Under side greyish, with small pale ochreous 

 and brown costal spots beyond the middle. Hind wings and cilia 

 grey. Under side whitish grey. Abdomen darker grey ; anal tuft 

 ochreous. Legs whitish ochreous. Exp. al. 16 mm.

 ^Argyrotoxaflavicostana, sp. n. 



Antennce, head, and face pale straw-colour. Palpi greyish 

 fuscous. Thorax greyish fuscous, narrowly margined anteriorly 

 with pale straw-colour; tegulae pale straw-colour. Fore wings 

 greyish fuscous, the costal margin pale straw-colour to beyond the 

 apical third ; the lower edge of the clearly-defined pale costal band 

 is somewhat sinuous and narrowly margined with whitish ; at 

 one-third from the apex a pale straw-coloured transverse streak, or 

 narrow fascia, reaches to the dorsal margin immediately before the 

 anal angle, where it is somewhat dilated, this fascia is much 

 attenuated (almost interrupted) below the costal band, with which 

 it becomes blended, it is narrowly margined on both sides by a 

 whitish line ; a pale whitish narrow sinuous line runs from the 

 anal angle around the apical margin; there are a few (4 or 5) 

 small greyish fuscous costal spots in the pale costal band, and a 

 series of spots (about 7) of the same colour runs down the centre 

 of the transverse fascia ; cilia pale ochreous, with one or two 

 darker lines. Hind wings rather pointed, with the outer margin
