Tthopalocera from Central Ceram. 399 



from New Guinea, the formation of the cell of the hind wing 

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

 cate the specific distinction of this form. 



The cell of the hind wing is longer and narrower than in 

 any other species of the group; upper discocellular longer, 

 and middle and lower discocellular shorter than in other 

 forms. 



Upperside with general pattern of goliath group. Fore 

 wing with green costal area as in suprenius, but less green 

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

 median green area as in supwenuts, its outer edge straighter 

 and further from the margin, and less sharply defined, hind 

 wing with black marginal border wider than in other forms ; 

 green markings more extended than in supremus, the veins 

 being more heavily marked, and the distal edge of the anibei- 

 coloured area being wider and extended round the apex; 

 three postdiscal spots placed as in suprenius, entirely green 

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

 streak in cell along its lower edge. 



Underside. — Fore iving as in suprenius, but more greenish. 

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

 broad, the veins more strongly edged with green distally, 

 some green sealing along costal edge, cellule 2 nearly filled 

 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 sttpremus and 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 suprenius. 



Length of fore wing 97-103 mm. 



The ? measures 116 mm., but a specimen has been obtained 

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

 expanse of 9^ inches. This is second only in size to alex- 

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

 135 mm. 



Described from 3 $ $ obtained on the Manusela Range, 

 Central Ceram, 2500 feet, October and November. 



We append some notes made by the collectors : — 



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

 rare, but is most easily obtained in the open country at the 

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

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

 goliath, titan, suprenius, and samson forms in New Guinea. 

 This is not the case with joiayi, which is apparently only 

 found in the steaming valleys surrounding the higher ranges, 

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

 O. rothschildSs limit is probably 5000 or even 6000 perhaps.
