50 Bibliographical Notices. Genus Prosopis. Prosopis mixtus. Female (length 2;^ lines) black ; the clypeus cream-coloured ; the tubercles and tegulse white ; the wings white, hyaline ; all the tarsi pale ferruginous ; the pubescence on the posterior legs white ; the margins of the abdominal segments testaceous ; the disk of the thorax is very smooth and shining. Hab. Ind. Although I have placed this insect in the genus Prosopis, I do not feel quite satisfied that it belongs to it ; in the neuration of the wings it exactly corresponds with that genus. I cannot ex-amine the tongue, and the specimen described is much mutilated and gummed to a piece of card, and is altogether in bad con-dition. I have described it, believing it to be an Hylceus, as it is to me a new habitat for the genus. BIBLIOGRAPHICAL NOTICES. A Naturalist s Sojourn in Jamaica. By P. H. Gosse. 1851. 12mo. Longman and Co. There are perhaps few parts of the world of whose natural pro-ductions we know less than those of our own West Indian Colonies. At first sight this may appear rather surprising, considering the number of Europeans constantly residing in those beautiful islands ; but as most of these regard the old country as their home, and their sojourn in the West Indies only as a means of making money, they are still, as in the time of Bancroft, " more attentive to the acqui-sition of wealth than natural knowledge." Occasionally indeed some clergyman or medical man does pay a little attention to the natural objects which surround him ; but the number of these exceptions is but small, whilst few of them ever do more for the preservation and publication of their observations than the insertion of a notice of some remarkable occurrence in one of the innumerable ' St. George's Chronicles ' or ' Kingston Gazettes,* or an occasional article in one of those red-covered almanacs, which, to European eyes, have such a curiously exotic appearance. The natural history of Jamaica has once or twice engaged the at-tention of naturalists and been made the subject of a special treatise, but much remained to be done, — how much, the present delightful volume, the result, or rather part of the result, of a "sojourn" of only nineteen months in the island, will abundantly show. Mr. Gosse is too well known as an acute observer of nature, and his reputation as an agreeable writer is too well established, to leave much doubt in the minds of our readers that a book from his pen on the natural history of Jamaica, perhaps the most beautiful of tropical islands, will contain an abundance both of information and entertain-
