31. Corzoptera. Vol. VI. part 2: by J. S. Baly and G. C, Champion: Phytophaga 
(part). 
This Volume gives an account of the Hispide by J. 8. Baly, published in 1885-1886, 
with a short Appendix, in 1894, by G. C. Champion; and of the Cassidide by 
G. C. Champion, published in 1893-1594. For the two families 453 species are 
enumerated—Hispide 226 (169 new), Cassidide 227 (59 new). The Central- 
American representatives of these groups are essentially N eotropical, America north 
of Mexico possessing a very limited number of species. Many of the characteristic 
South-American genera of Cassidide, however, do not reach so far north as Panama, 
or, if present, are represented by very few species. Mexico is particularly rich in 
peculiar forms belonging to the genera Che/ymorpha, Physonota, Coptocycla, &c. 
‘The Hispidee attack Musacee, Bambusacee, &c., and abound throughout the warmer 
parts of Tropical America. 
The thirteen coloured plates inclnde figures of nearly 300 species. 
82. CoLeoptera. Vol. VIL: by H. S. Gorham: Erotylide, Endomychide, and 
Coccinellidee. . 
The three families enumerated in this Volume are placed by recent writers in the 
Clavicorn-series, which are dealt with in Vol. II. part | of the present work. The 
total number of species is as follows:—Erotylide 282 (154 new) ; Endomychidee 
81 (39 new); and Coccinellide 239 (108 new). The Erotylide, including the 
Languriides, were published in 1887-1889, the Endomychice in 1889-1891, the 
Coccinellide in 1891-1898, and a short Supplement to all three families, and the 
Introduction, in 1898-1899. The Author, speaking of the Erotylide, exclusive of 
the Languriides, says that the members of this highly developed family of fungivorous 
beetles are largely endemic. The Endomychide are somewhat poorly represented in 
Central America; the Coccinellide, or ‘lady-birds,’ on the other hand, are very 
abundant in species and individuals, the phytophagous Epilachne in particular. The 
small Aphid- and Coccid-devouring Coccinellids have of recent years become of 
economic importance. 
The thirteen coloured plates include figures of nearly 300 species. 
This is the last of the eighteen volumes devoted to the Coleoptera; the total 
number of species enumerated is 18,029. Several genera of doubtful position, left 
undetermined by the various authors, have recently been described and figured, and 
the species of the genus Hapalips revised, by Mr. Champion (Trans. Ent. Soc. Lond. 
1913, pp. 58-169, pls. iii, iv.). 
83 Hymenoprera. Vol. 1.: By P. Cameron: Sessiliventria and Petioliventria. 
The fifteen families of Phytophagous or parasitic Hymenoptera worked out in this 
Volume number in all 1109 species, of which 596 are described as new. The
