represented in the Joicey collection, and presumably tlirongh- 

 out the {jenus. /Snellen's challenge of it (Tijd. v. Ent. 

 xxviii. p. 11) was due to his erroneous composition of the 

 genus, and it is carious that Hampson, who has purified it, 

 has not noticed the palpal structure in more detail. 



12. Lagoptera rubida velutina (Warr., MS.?), subsp. n. 



$ . — Differs from rubida rubida. Walk., as follows : Pectus 

 much darker, strongly mixed with dark grey- brown. 



Fore wing with posterior spot of reniform stigma (not 

 mentioned in Hampson's description) much larger, nearly 

 confluent with anterior spot, pale with dark centre ; anterior 

 part of postmedian line more sharply defined ; pale distal 

 border of more uniform width nearly to toruus, then 

 obliquely cut off, the ground-colour running to tornus. 



Hind icing with the blue-white band at least twice as 

 broad (5 mm.), narrowing gradually at its extremities. 



Underside rather more smoky than in r. rubida. 



Arfak Monntains, Dutch New Guinea (Pratt), type and 

 another, the type from Angi Lakes, 6000 feet, ]March 1914; 

 the type labelled by Talbot "Lagoptera rubida velutina 

 Warr.," which must be an unpublished name.

13. Lagoptera ochrobrumiea. Strand. 



Lagoptera inversa ab. ockrobrunnea, Strand, Arch. Nat. Ixxix. A, (8) 

 p. 71 (1914) ( = ab. 1, Hmpsn., Cat. Lep. Phal. xii. p. 419J. 



It was overlooked by Hampson that this is a perfectly 

 distinct species, and the differentiation from true inversa, 

 AValk. ( = bivirgata, SnelL), though just sufficient to give 

 validity to Strand's name, needs supplementing. 



cJ $ . — Size and nearly shape of inversa, distal margin 

 of hind wing perhaps slightly more irregular. Head and 

 thorax more tinged with ochreous, pectus and underside of 

 palpus clear ochreous. Abdomen rather paler, beneath more 

 mixed with ochreous. 



Fore wing more ochreous-brown than in inversa ; subbasal 

 line obsolete, except for the feeblest traces costally ; ante- 

 median rather more proximally placed ; median area ample 

 (8-10 mm. wide), containing in addition to the reniform a 

 black proximal dot representing the orbicular ; distal area 

 without pale line in front of K,^ ; narrow pale terminal baud 

 rather broader and more variegated than in inversa. 



Hind wing with the bluish-white band much narrower and 

 shorter than in inversa ; white patches on fringe more 

 ochreous and more extended than in inversa.
