( 115 ) VI. A 2^'}'eH7nma'}-y catalogue of the Lepidoptera Heterocera of Trinidad. By William James Kaye, F.E.S. [Read February 5th, 190L] Plates V. and VI. Although Trinidad is within such easy reach of England, and has the inducement to visitors of being in a civilized state, its Lepidopterous fauna has been almost wholly neglected, and no scientific lists have been published, except the preliminary list of the butterflies by Mr. Crow-foot in the Transactions of the Trinidad Literary and Philosophical Society. This is all the more remarkable as the fauna is an exceedingly rich one, as one might expect in an island belonging to the Neotropical Region and lying so near to the Equator. The butterflies enumerated in Mr. Crowfoot's list number up 199, and this is far short of the actual total as my own records can show. If one can compute at all the number of Heterocera., it should, without including Tortricid/i} and Tineidie, not fall far short of 1000 sjDecies even at a modest estimate. I have been able to record only 245 at present, not including the Tortrieidie and Tiiieidm, but I hope to supplement this number at a future date. Hitherto nothing has, I believe, been published on the moths of Trinidad. It has therefore been necessary to search through the specimens at the British Museum for Trinidad labels. Comparatively few have been found, and tiie species are mostly those taken by my brother, Mr. S. Kaye, at Verdant Vale in 1895, and my own captures in various parts of the island in May and June 1898. My best thanks are due to Sir George Hampson for valuable help and advice in the compilation of this list. I have presented the types of new species to the British Museum. Family SYNTOMIDiE.
