        "content_text": "98 \n\nV. R. BURKHARDT \n\nKong,\" published in 1907 illustrated about that number. Since the last war a dozen entomologists have added to the check list, and over fifty fresh discoveries have been made. The most striking was the large \"bird-wing\" ornithoptera Troides helena (Linn.) found in abundance in an obscure wood in the New Territories by Wallis in 1952. The butterfly is black with yellow hind wings and the male has a span of five inches whilst his mate has three quarters of an inch more. Eggs and larvae were found on aristolochia, a creeper which imparts an unpleasant taste to the larvae of this and other insects which patronise it as a food plant. Unfortunately the local villagers stripped the trees of the vines and Troides helena has not been recorded since 1958. In the two years of its abundance several people bred the butterfly from the egg. Its larva is very similar to that of Papilio aristolochiae being black, with numerous processes like fleshy spines, and a white belt in the centre of the body.\n\nPAPILIO PARIS \n\nWhilst England has only one of the Swallowtail family, Papilio machaon, which is confined to the fens of Cambridge and Norfolk, Hong Kong can count seventeen, many of which are very common. Perhaps the most striking is Papilio paris whose sapphire hind wing patch catches the eye as the insect flashes past. The ground colour is rifle green, spangled with gold dust. When freshly emerged the patch is the greenish blue of a turquoise, but these outer scales are shed in flight, and the under feathers are a brilliant sapphire blue.\n\nThe butterfly is to be seen throughout the year except for the winter months from about mid December to mid February, the cycle from egg to imago being about sixty days. The eggs, globular and of a greenish tinge, are laid on the underside of the leaves of Xanthoxylum nitidum, a prickly woody climber or half climbing shrub, very common in the Colony. An alternate food plant is Todalia asiatica, a prickly bush, which is rather scarce, but much appreciated by Papilio paris where it occurs.\n\nWhen the young caterpillars hatch they are brownish in colour, though after the first moult they change to light green. The second, third, and fourth segments are much swollen and two processes form on each of these segments, those on the second being the most pronounced.",

Those interested in genealogies from Kwangtung should compare it with the lists of holdings in the Fung Ping Shan Chinese Library, University of Hong Kong and elsewhere, given in Lo Hsiang-lin's A Study of Chinese Genealogies (†☎##6X), Hong Kong, Institute of Chinese Culture, 1971, pp. 211-240.\n\nHong Kong. April 1977.\n\nHon. Editor.\n\nTHE OCCURRENCE OF TROIDES HELENA (LINN.) IN HONG KONG\n\nJ. CAREY-HUGHES, B.Sc., F.Z.S. AND JOHN BERRY PICKFORD\n\nTroides helena, the Common Birdwing, has an extensive range in the Indo-Australian faunal zone and was first discovered in Hong Kong by WALLIS in the New Territories, and bred by him and POTTER (a collector who bred several other butterflies through from egg to imago and recorded his findings in The Hong Kong Naturalist Vols. IX and X) from the larva. This is recorded by ELLIOT in his Check-list of December 1953.(1) The insect, apart from years of population explosion, is rare in Hong Kong which must be situated near the northernmost limits of its range.\n\nThe butterfly is spectacularly beautiful and its high soaring flight about the tops of trees is a memorable sight. The forewings are black with white-dusted veins and the hindwings black and gold as can be seen from the illustrations. The females are larger than the males having a wingspan of up to 13 cm. although this is exceeded in other parts of its range where measurements of up to 18 cm. have been noted. Males and females are easily distinguishable even on the wing by their different pattern, apart from the size.\n\nOur first encounter with Troides helena took place in 1958 when a male and female were captured in two isolated areas of the New Territories. Sporadic sightings occurred between then and 1967, although BURKHARDT, in a conversation with one of us, expressed the opinion that he thought the insect was extinct in Hong Kong and mentioned in Vol. IV of the R.A.S. Journal that the butterfly had not been seen for a number of years.(2)",
