NOVITATES ZOOLOOICAE XXIV. 1917. 305 



with black ; pectinations in <?, at their longest point, scarcely three times diameter 

 of shaft. Thorax and abdomen as in the allies (chlorargyra group). 



Porewlng bright green, rather more yellowish than in the allies ; the white 

 costal edge rather broad, strongly tinged (excepting the pure white basal sub- 

 costal streak) with red and — -especially at costal extremity — with some metallic 

 blackish irroration ; midcostal streak rather broad and reaching to the posterior 

 end of DC ; distal border of equal width throughont, its white element con- 

 tinuing round the apex between SC and SC* to about 3 mm. from termen, where 

 it curves forward in a cedilla-shaped mark and is lost in the reddish suffusion ; 

 oblique mark from tornus fairly broad but rather short., pure white, only at 

 extreme tornus tinged with yellow. — ■ — Hinclwing as in the allies. 



Underside with the suffusions predominantly greenish, on the hind wing 

 almost entirely so. 



Upper Aroa River, British New Guinea, March 1903, type S, and February 

 1903, ?; Kumusi River, N.E. British New Guinea, low elevation, August— - 

 September 1907. All in coll. Tring Museum, collected by A. S. Meek. Also from 

 Penang and Perak in the same collection and from Singapore and Borneo in coll. 

 Brit. Mus. 



The <J antennal pectinations are much shorter than in an}' other of the 

 group, unless it be the very distinct iodioules T. P. Luc. ( = eucraspeda Turn., 

 syn. nov.),* of which only the ? is known. 



31. Pyrrhorachis pyrrhogona (Walk.). 



I am now inclined to think that Warren was correct in separating his cornuia 

 (Nov. ZOOL. iii. 292) as a distinct species. If not, it is a constant race with very 

 wide distribution (New Guinea and its satellite islands and again on Borneo 

 — not yet kno\\Ti to me from the intervening area). In any case the forms still 

 left under pyrrhogona vary geographically. Walker described from South India 

 and his form has the distal border of the forewing rather narrow, not swelling 

 appreciably at the tornus. The AustraUan form, marginata T. P. Luc, seems 

 only separable by its larger size. 



P. p. angnstata ( Warr. MS.) subsp. nov. A single 9 in coll. Tring Museum, 

 from Lifu, Loyalty Islands, has the distal borders still narrower, thread-Uke. 



Another uniqtie specimen, deliciosa Warr., from the Natuna Islands, may 

 be a subspecies with the border broadened and not traversed by blackish metallic 

 scaling, but as the hindwing is rather less elongate, I have left it provisionally ag 

 a separate species. 



P. p. tnrgescens subsp. nov., from the Khasis, is easih' and constantly dis- 

 tinguishable from the name-type by having the marginal spot between tornus 

 and M' of the forewing considerably enlarged, more than twice as broad as the 

 rest of the series ; the apical and tornal borders of the hindwing also show a 

 tendency to enlargement. Type in coll. Tring Museum. 



It is desirable to add that the specimen from which the genitalia were 

 diagnosed {Gen. Ins. fasc. 129, p. 239) was a Khasi example (subsp. turgescens) 

 in my collection. 



* Lucas's type is in coll. Tring Museum. It was unknown to me when I prepared Pt. 14 of the 

 LepidopUrorum Catalogus, and I merely cited the name under Agathia, in which genue its author 

 quite erroneously published it.
