the whole of the subfamily Calandrine being here dealt with. An Appendix to the 
Curculionide is added, on pp. 178-212, enumerating a few additional forms and 
making some corrections to the synonymy. ‘The Cossonina and Calandrinz are each 
represented in Central America by a large number of species, some of the Calandrids 
attacking palms, cacti, sugar-cane, maize, Musacew, &c. The Mexican Cossonids (the 
genus Cossonus excepted) had been previously studied by Wollaston and the Calandrids 
by Chevrolat, nevertheless, with more abundant material, many new forms were found 
in our collection. Altogether 344 species are enumerated, 231 of which are described 
as new. ‘The nine plates are coloured or partly coloured.

The greater part of this Volume (pp. 1-436), published in 1879-1885, is devoted to 
the enumeration of the Longicornia by Mr. Bates, the Bruchides, by Dr. Sharp, 
published in 1885, occupying pp. 437-504. Altogether the two tribes number 1445 
species: Longicornia 1273 (648 new), Bruchides 150 (117 new). Mr. Bates, 
in his Introduction to the Longicornia, published in 1886, remarks as follows: 
“Compared with the Tribe Geodephaga, it is beyond doubt far more numerously 
represented in tropical than in extra-tropical lands, and its species and genera are 
naturally multiplied in the highest degree in tropical forests, where woody vegetable 
growths, to which the Longicornia are almost exclusively attached in their larval states, 
are most numerous and varied. Although their beauty of form and colour has led to 
their having been industriously collected, it is evident, from the number of new 
species continually arriving from countries supposed to be fairly well explored, that we 
are as yet far from possessing even an approximately complete knowledge of the whole 
product of Nature in this department. ‘his is partly due to the recondite and, to a 
great extent, nocturnal habits of a vast proportion of the species, and the difficulty of 
the search for them in dense primeval forests where few clearings offer the necessary 
openings.” The author thinks that the main conclusions arrived at after a similar 
examination of the Geodephaga are confirmed, viz. (1) that the Central-American 
fauna is essentially Neotropical ; (2) that the northern portion of the region (Mexico 
and Guatemala) is not an extension southward of the Nearctic Province, but (3) that 
it is a remarkably distinct subprovince of the Neotropical fauna, Dr. Sharp, 
in his remarks on the Bruchides, numbering 150 in all, says (p. 437) that our 
knowledge of these insects is not sufficiently advanced to enable any trustworthy 
generalizations to be made in reference to the species found in Central America ; 
and, as the northern parts of Mexico had been inadequately explored, it was not 
possible to say what relationship existed between the North American species and 
those of the regions southward.
