 fuscous, in ^ more densely, abdomen with double dorsal series of black spots. Antennal 

 pectinations of t very short, tooth-like, terminating in fascicles of cilia. Forewings 

 rather elongate-triangular, termen hardly rounded, very oblique ; white, with indistinct 

 striae of fuscous and black irroration, in ^ largely suffused with fuscous and densely 

 irrorated with dark fuscous ; basal patch of four slightly curved striae, in ^ dark fuscous, 

 in ? blackish ; median band formed of seven or eight striae, in ^ dark fuscous, in ? 

 blackish, anterior edge curved, somewhat indented below middle, posterior irregular, 

 middle third forming an angular prominence ; an inconspicuous black transverse discal

2 $s, Haleakala, Maui, at 6000 — 8000 feet, above forest level, in May ; Mr Perkins 

 did not obtain a ^, and I have therefore described one received from Mr Blackburn, 

 taken in the same locality, and quite similar to the type specimen in the British 

 Museum. The sexes are dissimilar in appearance, the ^ being larger, greyer, and more 

 obscure, the $ whiter and more sharply marked, but I think there is no doubt of their 

 identity. 



(3) Xantliorhoe leucoxyla, sp. nov. 



?. 34 mm. Head, thorax, and abdomen ochreous-whitish mixed with pale 

 ochreous, abdomen with double dorsal series of suffused ferruginous-ochreous spots. 

 Forewings somewhat elongate-triangular, termen gently rounded, oblique ; ochreous- 

 whitish, with indistinct ferruginous-ochreous striae ; basal patch of four slightly curved 

 suffused darker striae, costal edge dull crimson near base ; median band of about six 

 similar striae, anterior edge acutely indented beneath costa, posterior with middle third 

 forming an angular prominence ; a round black discal dot ; subterminal line forming a 

 series of small indistinct white spots, one at \ from costa preceded by a small round 

 blackish spot. Hindwings elongate, termen rounded, hardly waved ; ochreous-whitish ; 

 a median band of several faint fuscous striae. (Plate IV. fig. 24.)
