tlie leaves of tlie food-tree, and tlie imago emerges about 

 October and continues to be found tlirougb November. There 

 is only one brood in the year. This handsome moth is not 

 very uncommon, the larvae and pupae are largely preyed upon 

 by magpies and wattle-birds." Further reference to this species 

 will be found Trans, of this Society vol. iv., p. 142 (Editor). 



Clioragict sp. — " Expanse of wings in male If inch, in female 

 2\ inches. The great peculiarities of this species are the 

 extremely short antennae of male, extraordinary shape of the 

 first pair of legs, and the almost entire absence of the third 

 pair of legs. 



The fore wings of female are dull, smoky red, with a large 

 dull-coloured triangle of green towards apex of wing, beyond 

 which is another smaller one. Hind wings reddish- salmon 

 colour. Abdomen of female extraordinarily long. 



The larva is hard-headed, dirty-white. It gnaws the bark in 

 a ring around the branch of Melaleuca?, and makes a large 

 nearly circular pit on one side of the branch, all of which are 

 covered with a dense opaque web of silk ; then it eats down 

 into the pith. It feeds for two years, and remains in the pupa 

 state never more than a week. The perfect insect emerges in 

 January, but it is local and rare."

Note on the occurrence of a Second Species of Crocodile 

 IN Arnheim Land. By Prof. E. Tate. 



The common crocodile of the estuaries of the Adelaide, 

 Alligator, and other rivers of Arnheim Land has long been 

 scientifically known, having been identified by Gray as 

 C. porosus. 



While at the Port Darwin I saw in the possession of In- 

 spector Foelsche a small gavial-like species, which I refer un- 

 hesitatingly to C. Jolmsfoni, KrefPt, P.Z.S., 1873, p. 334, and 

 Gray, id., p. 177, tab. 27, 1874, described from a Queens- 

 land example. Inspector Foelsche informs me that the species 

 has been known to him for several years, and that it inhabits 

 the inland lagoons and creeks, and appears to be plentiful, and 

 that as far as he can learn it lives only in fresh water. The 

 eggs are long and narrow.
