ZOOLOGY. 69 
Allocorynine, and Thecesternine, each including a few species only, are common to 
North America and Mexico or Central America. The apterous Otiorrhynchids are 
mostly restricted to the central plateau—Hupagoderes, Epicerus, and Epagriopsis 
being the dominant genera in the highlands of Mexico,—while the winged forms 
preponderate in the warmer forest regions to the east, west, and south, this 
distribution being similar to that of the Tenebrionids. Pandeleteius and Pantomorus 
are characteristic winged genera in the open country. Various papers on the 
Apionine by Herr Hans Wagner, in which additional species from our region are 
described, have been published during recent years. Unfortunately, very little 
is known as yet of the actual food plants of any of the Central-American 
Rhynchophora. 
The fifteen coloured plates include figures of nearly 400 species. 
24. CoteopTreRA. Vol. IV. part 4: by G. C. Champion: Curculionide (part). 
The whole of this Volume is devoted to the Subfamily Curculionine, which are so. 
numerous in the forest regions of Tropical America as to deter most Coleopterists 
from venturing to describe them. Twenty-two groups are enumerated, the Sitonina 
to the Cryptorrhynchina inclusive, numbering in all 1365 species, 1146 of which 
are treated as new. Some of the genera include a very large number of species: 
Conotrachelus (nearly 200), Anthonomus (over 100), Hilipus, Otidocephalus, Cryptor- 
rhynchus, Kubulus, &c., so that it seems an almost hopeless task to prepare a complete 
list of these insects. Dr. Sharp and Mr. Champion have been the first to describe 
the whole of the Curculionide of a tropical country, and, though the genera of the 
Cryptorrhynchina still remain in inextricable confusion, the present contribution will 
doubtless be of considerable assistance to future workers. Some of the Groups, 
Anchonina, Cholina, &c., are purely Neotropical ; others, Pissodina, Sitonina, Hyperina, 
Balaninina, Cleonina (Lirus excepted), belong to more temperate regions, but extend 
southward to within our limits. 
The thirty-five plates include figures of nearly 1000 species: nineteen (x. and 
XVill.—-xxxv. inclusive) are coloured, one (xii.) partly coloured, and the rest 
uncoloured. 
25. CoLEorTeRA. Vol. IV. part 5: by G. C. Champion: Curculionide (continued). 
This Volume deals with four more Groups of the Subfamily Curculionine—the 
Zygopina, Tachygonina, Ceuthorrhynchina, and Barina, the vast complex mass known 
as Barina being represented by eleven Sections, all but three of which are purely 
tropical. The Zygopina also are almost entirely tropical, a few forms only occurring 
north of the Mexican frontier and they are wholly wanting in the European fauna..
