544 INSECTS ABKOAD. 



stripes so closely resemble the plumage of the trogon, that the 

 Butterfly was named Papilio trogon. This is a much better 

 name than that which is now given to it, but as the latter name 

 was found to have precedence in point of time, it must be 

 retained. Beneath, the wings are black and green, changing 

 towards the base into a deep, rich blue when viewed by a side 

 light. The thorax is entirely crimson above, and of the same 

 colour below, but barred with black. 



" This species," writes Mr. Wallace, who discovered it in 

 1855, " which was then quite new, and which I named after Sir 

 J. Brooke, was very rare. It was seen occasionally flying swiftly 

 in the clearings, and now and then settling for an instant at 

 puddles and muddy places, so that I only succeeded in cap- 

 turing two or three specimens. 



" In some other parts of the country I was assured it was 

 abundant, and a good many specimens have been sent to Eng- 

 land, but as yet all have been males, and we are quite unable to 

 conjecture what the female may be like, owing to the extreme 

 isolation of the species, and its want of close affinity to any 

 other known insect." 



The second figure represents Papilio Panthous, a species which 

 inhabits Amboyna and Ceram. 



The figure represents the male, and is slightly reduced on 

 account of the exigency of space. The female is very much 

 larger, her extended wings sometimes measuring more than 

 eight inches from tip to tip. 



The upper surface of the wings is shining black with grey 

 streaks, and the under surface of the upper pair of wings is 

 coloured in much the same manner, except that the black and 

 the grey are both dull. The lower wings are brilliantly coloured. 

 A stripe of black begins at the base and runs round two-thirds 

 of the wing. It is very broad at the base, and narrows with the 

 anal angle, where it terminates. On the stripe there are six 

 large yellow marks, arranged as shown in the illustration, those 

 towards the base of the wing being orange and the other golden 

 yellow. The centre of the wing is pearly white in the male, ami 

 duller in the female, with several large oval black spots. 



The thorax is velvety black, and the abdomen is of the same 

 colour, but adorned with several large spots of orange.
