( to ) II. New Lepidopteia from (he Schouten Islands. By J. J. Joickv, F.L.S., F.Z.S., F.E.S., and G. Talbot, F.H.S.. with description of a new Tineid by J. Hartley Durrant, F.E.S. 1 1 toad October 6th, 1915.] Plates III-VI. The present paper is a continuation of one on Biak Lepido-ptera by Messrs. Joicey and Noakes which appeared in the Transactions for 1915, Part II, p. 177 et seq. The specimens were collected mostly on Biak by Messrs. A., C, and F. Pratt during May and June 1914, and some were obtained on the adjacent island of Soepiori (Mysore) at Korrido. The types are in the collection of Joicey except where otherwise stated. It may be said here that the expedition made by Messrs. Pratt to the Schouten Islands has added greatly to our knowledge of their Lepidoptera. The present paper brings the number of new forms discovered by these indefatigable collectors up to sixty-one. The following notes on the island of Biak and its Lepido-ptera, communicated to us by Mr. Felix Pratt, will be of interest. Very little information on this island is to be found in geographical literature. " On Biak, as on most islands out here, the commonest insects are Danaids and Satyrids. To the east, Appias and Catopsilia, particularly the former, were exceedingly common, i. e. for this part of the world. In South America forty to fifty Catopsilia in one sweep of the net is quite possible on a mule road. Such a take out here is an im-possibility; four or five at once would be unusual. To the west, although the country is open and suitable to rapid-flying Pierids. the Appias and Catopsilia were con-spicuous by their absence. In fact, speaking from the standard of mos1 tropical islands, butterflies in general are rather rare on Biak. " The difference between the forms on Biak and their TRANS. ENT. SOC.
