My entomological collections were much more complete than my collections of birds, especially those of the butterflies and beetles.* [* The author's bird and insect collections were purchased at his death by Messrs Godman and Salvin who also acquired from Mr. H.W. Bates the types and other specimens of coleoptera described by him which had not remained in the original collection. These are all now in the British Museum, together with the Hewitson bequest, in which are many of the lepidoptera types. It may not be out of place to add that Mr. Hewitson left in his will the sum of two hundred pounds to Belt in recognition of the way in which the latter's collections had been placed at his service.] Mr. W.C. Hewitson has described twenty-five new species, but no list of the whole of the butterflies known from Nicaragua has yet been published. In Coleoptera I made large collections, but the extensive families of the Elateridae, Lamellicorns, and others are still uncatalogued, and very many species remain to be described. The only beetles that have been catalogued as yet with sufficient completeness to warrant any general conclusions are the Longicorns. I collected about 300 different species, and Mr. H.W. Bates has enumerated 242 of these in a paper "On the Longicorn Coleoptera of Chontales, Nicaragua," published in the "Transactions of the Entomological Society" for 1872. In an interesting summary of the results he gives the following analysis of the range of the species:-- Peculiar to Chontales: 133 species. Common to Chontales and Mexico: 38 species. Common to Do. and the West India Islands: 5 species. Common to Do. and the United States: 5 species. Common to Do. and New Grenada or Venezuela: 24 species. Common to Do. and the Amazon Region: 22 species. Common to Do. and South Brazil: 10 species. Generally distributed in Tropical America: 5 species. Total: 242 species. Omitting the peculiar species and those generally distributed in Tropical America, we have thus forty-three that are found in Chontales and in Mexico or the United States, and sixty-one that are found in Chontales and countries lying to the southward. The preponderance of southern forms is not so great as in the birds, but when we reflect on the large number of peculiar species, and that the Longicorns of the Atlantic slope of Costa Rica are yet scarcely known, it appears likely that many of the Chontales species will be found ranging southward across the San Juan river, and that the Insect fauna will be shown to have the same relations as the Bird fauna; for, as the Atlantic forest continues unbroken much further southward than northward, so will the insects peculiar to the forest region have a greater range in that direction. Mr. Hollick has beautifully drawn on wood a few of the characteristic Longicorns of Chontales, all of them, with one exception (Polyrhaphis fabricii), being as yet only known from that province, but probably extending into Costa Rica.
