583 ) XX. A List of the Coleoptera of the Maltese Islands. By Malcolm Cameron, M.B., R.N., and A. Cahuana Gatto, LL.D. [Read March 20th, 1907.] In publishing this contribution we trust that it may be of some service to collectors and those interested in the distribution of species. We must acknowledge our indebtedness to the following gentlemen, who have been good enough to examine some of the species: — MM. Fauvel, Keitter, Pic, Regimbart, Desbrochers des Loges, Dr. David Sharp, and Mr. E. A. Newbery ; also to Mr. G. C Champion, who has kindly allowed us to see many species from the collection of Commander J. J. Walker, R.N., which had not been obtained by us, and which in the list are noted as Coll. J. J. W., or teste J. J. W. Names of species in brackets are those which have not come under our notice, although recorded by others. The order and nomenclature adopted throughout is that of the " Cat. Col. EuropEe " of Heyden, Reitter, and Weise (1891 edition). The figures refer to the months. General Description of the Maltese Islands. The group of the Maltese Islands consists of the two islands of Malta and Gozo, and of the small islets of Comino, Cominotto, and Filfola. Malta, which is the main island, is l7i miles in length and 83-miles in breadth, its area being 1)5 square miles ; Gozo is 9 miles in length, 4| in breadth, and has an area of 20 square miles; Comino has an area of about 1 square mile, and Cominotto and Filfola are even smaller. They are situated almost at the centre of the Medi-terranean ; the distance from Capo Passero in Sicily is about 60 miles, and from the nearest point in Africa about 200 miles. Close to the African shore lies the island of Lampedusa, and further west, midway between Sicily and Africa, the islands of Linosa and Pantelleria. Both with TRANS. ENT. SOC.
