Rhopolocera from Central Cerani. 399 



from Nev<^ Guinea, the formation of tlte cell of the hind wing 

 and the special pattern of the female seem sufficient to indi- 

 cate the S|)ecitic distinction of tliis form. 



Th(; cell of the liind win": is longer and narrower than in 

 any other species of tlie j^ronp; upper discocellubir longer, 

 and middle and lower discocidluiar short^'r than in other 

 forms. 



Upperside with general jiattern of goliath group. Fore 

 lohxg with green costal area as in supremusj hut less green 

 along upper part of cell and distally of this. Postdiscal and 

 median green area as in siipremiis, its outer edge straighter 

 and further from the margin, and less sharply defined. Hind 

 wing with black nuirginal border wider than in other forms ; 

 green markings more extended than in supretnus, the veins 

 being more heavily marked, and the distal tdcra of the ainbei- 

 coloured area being wider and extended round the apex; 

 three postdiscal s{)ots placed as in supremu^, entirely green 

 and mostly touching the vein-streaks of 4, 5, and 6; a green 

 streak in cell along its lower edge. 



Underside. — Fure wing as in supremus, but more greenish. 

 Hind wing as in supremus, but green marginal area twice as 

 broad, the veins more strongly edged with green distally, 

 some green scaling along costal edge, cellule 2 nearly tilled 

 in with greenish yellow except for a small amber spot or 

 streak. The postdiscal spots are placed a little further from 

 the green margin than in supremus aiul are black edged with 

 green. 



Head, thorax, and abdomen as in allied forms. The scent- 

 gland and hair are of the same colour as in .'■supremus. 



Length of fore wing 97-103 mn). 



The ? measures lit) mm., but a specimen has been obtained 

 which is said to measure 120 mm. (about 4|"), making an 

 expanse of 9i inches. This is second only in size to a/ex- 

 imdrte, which has attained a maximum length of fore wing of 

 135 mm. 



Des(;iibe(l from 3 (^ c^ obtained on the ]\Ianus(da Range, 

 Central Ceram, 2500 feet, October and November. 



We append some notes made by the collectors : — 



"With regard to 0. procun, the insect seems to be very 

 rare, but is most easily obtained in the o|)en country at the 

 foot of Mount Moekele at 2500 feet. It is obviously not a 

 coast insect, but is a fairly low form correspoinling to the true 

 goliath^ tilan, nujnemuft, and samsou forms in New Gninea. 

 This is not the case with joic<yi, which is apparently only 

 found in the steaming valleys snrrounding the liight r ranges, 

 and we think it doubtful if it descends below 4000 feet. 

 0. rothschihli^a limit is probaldy 5000 or even tJtlOO perhaps.
