Phtheochroa, Stph. 



Phtheochroa (?) albiscutellum, sp. n. 



Antennce simple, or very slightly ciliate towards apex; 

 wjiitish cinereous, basal joint cream-white. Palpi and head 

 cream-white. Thorax cream-white ; tegulte with a black 

 spot at their base. Fore wings cream-white ; with a short 

 basal patch of mixed black, cream-white, olive-brown, and 

 some ferruginous scales, the black being arranged in two or 

 three costal spots, with one above the fold and one beneath 

 it ; beyond the basal patch, on the costa, are two olive-brown 

 quadrate spots containing some blackish dots, and between 

 and below these two, but not touching them, is the apex of a 

 transverse band arising from the middle of the dorsum and 

 consisting of numerous tufts of raised steel-grey scales, 

 margined outwardly with black, the whole fading into pale 

 olive-brown before the dorsum, with which it is connected by 

 three blackish marginal dots, forming part of a more com- 

 plete dorsal series; on the apical fourth of the wing are two 

 very faint olive-ochreous bands, with silvery white lines 

 between and around them, containing one or two tufts of 

 mixed shining white and silvery grey scales ; these are sepa- 

 rated from the apex, first by a narrow band of shining white, 

 and then by a streak of ferruginous brown mixed with blackish 

 scales which crosses the wing from before the apex to the 

 middle of the termen ; beyond it the apex and termen are 

 olive-brown shaded with greyish fuscous ; cilia olive- 

 ochreous, touched with greyish fuscous towards their apex. 

 Exp. al. 21 mm. Hind wings pale brownish ; cilia whitish, 

 with a slender pale brownish shade along their base. Abdo- 

 men pale brownish. Legs cream-white; hind tarsal joints 

 spotted above with pale brown.

 in having veins '6 and 4 separated at their origin by a very 

 small space.
