258 XANTHORHOE. By L. B. Proit. 



line of hindwing as irregulär as in any sordidata, tliat of forewing mucli less so. Mount Goliath, Diitch New 

 Guinea, January 1911, only the tyjDe (^ known. It may be regarded as a link with Aeschrosfoma. 



caustoscia. X. caustoscia Jleyr. (25 1). The largest Hawaiian Xanthorhoe and distinguishable by its dentate hind- 



wing. Otherwise not at all a striking specdes, though some slight reddish or purplish suffusion relieves the dark 

 ground-colour. The pale subterminal line is in the $ better developed and forms a conspicuous white dot behind 

 the 3rd radial. Pectinations of the c^ antenna fairly long. Maui and Lanai, 3000 to 5000 feet, 



instihiris. X. insularis Biitl. (25 1). Less brown than caustoscia, the wings elongate, the termen of the hindwing 



scareely waved; median band distally much more sinuate and lobed. Variable, the $ smaller, whiter and more 

 sharply marked than the t^. Hawaiian Islands, at high altitudes. 



ioxaniha. X. ioxailtha Meyr. (25 1). Distinguished at once by the orange ground-colour of the forewing; hindwing 



except at abdominal margin, paler. Our figure shows the type of maculation. A $ from Kaholuamano, Kauai 

 (Hawaii), 4000 feet. In the abscnce of the ,^, the systematic position is uncertain. Perhaps related to Euphyia 

 leucoxyki. 



jinitima. X. (?) fitlitima Walk. (25 1), founded on 4 $$ from the Isle of Pines (Kuni) has also been tentatively 



referred to Xanthorhoe. but may probably, like "X." leucoxyla Meyr. (Euphyia), be found to have simple c? 

 antenna. Excepting the type, whicli has lost one hindwing, all are torn and more or less rubbed, but they 

 evidently do not vary and our figure of the type will make it recognizable. Face with jDointed cone; palpus 

 about twice diameter of eye, 2nd Joint heavily long-scaled. Distal margins almost smooth; hindwing somewhat 

 elongate anteriorly. Median band of forewing little narrower posteriorly than anteriorly, in part pale, at least 

 round the minute cell-dot, 2 or 3 antemedian and 3 postmedian lines on it fairly distinct. Under.side weakly marked. 



pallida. X. pallida Rothsch. (25 1). Palpus nearly 2, rough-scaled. Pectinations longish (4 or 5), ajiical -/- of 



antenna non pectinate. Abdomen slender. Scaling smooth and thiii. The hindwing, which is white and almost 

 unmarked above, is adorned beneath with a very characteristic fuscous suliterminal band its proximal boundary 

 (near the jjostmedian) a merely waved and very little curved line, its distal (indicating tlie white subterminal 

 line) very irregularly and strongly dentate the prongs Coming between the veins. Tlie forewing beneath is also 

 more .strongly marked than above and the hindwing (though unfortunately rubbed) shows the remains of several 

 dark lines between the base and the postmedian. Dutch New CJuinea: Carstensz Peak, Oetakwa River, 13 000 

 feet, February-Marcli 1913 (A, F. R. Wollaston), the unique type on the Tring Museum. The texture and 

 facies show the characteristics of a high-mountain species. 



vuh/aris. X. vulgaris Rothsch . (26 a). Palpus al)out as in paUida, pectinations somewhat longer and continued 



to nearer the tip of tiie antenna. A very .simple and imostentatious brown-grey species, showing very little 

 Variation. Underside with the forewing less, the hindwing more, strongly marked than above. Dutch New 

 Guinea: Oetakwa River in numbers, from 4000 to ßOOO feet; also 2 $$ have been taken on Mount Goliath, 5000 

 to 7000 feet. 



albiapicata. X. alblapicata Warr. (2t) a). This and the succeeding Papuan species, as far as alhirivala. probably 



form a natural group, \\ith the frontal tuft generally slight, the palpus shortish, the pectinations short or mod- 

 erate, the coloration (as least of the hindwing and underside) dark and glossy. From the other 2 small species 

 of the group, cdtnapicafa. is at once distinguishable by the sharply white mid-subterminal dot; there is usually 

 also much pale or white marking in the apical region (but this is variable) and always the pure white a n t e r i o r 

 half only of the postmedian line arrests attention. Owen Stanley Range and Mount Goliath. 



fulvinolaki. X. fulvinotata Warr. (2(1 a) has more white markings than any of its neighbours and the large "fulvous" 



brown patch between the postmedian and subterminal of the forewing always Stands out conspicuously. Anga- 

 bunga River and Biagi, with allnapicafa. 



hifulvata. X. bifulvata Warr. (20 a). Much darker, the bright brown outer shade less con.spicuous but extended 



into a band, a similar proximal one rei3lacing tlie much greyer band which occupies the same position in fulvi- 

 notata. Underside without the white mid-subterminal spot which is reproduced from the upperside in julvi- 

 notata and with the liindwing more regulaiiy ripjjled with whitish lines. Angabunga River. 



coeruleata. X. coeruleata Warr. (2(1 a). Much larger, pectinations proportionally nearly as short as in bifulvata. The 



whitish markings on the wings strongly tinted with a somewhat metallic blue, the fringe-spots white; a warm 

 brown patch on forewing plaeed as in fulvinotata. but occasionally obsolete. Owen Stanley Range and Gooden- 

 ough Island; type from Angabunga River. 



monastica. X. ttionastlca Warr. (26 b). Variable in size, otherwise almost constant. Forewing more unicolorous, the 



only strongly dark lines being the two which bomid the median area and a median well outside the cell-mark;
