70 CONTENTS OF EACH VOLUME. 
The Ceuthorrhynchina, on the other hand, are numerous in temperate regions and 
but poorly represented in the tropics. Of the 908 species enumerated for the four 
groups mentioned, 620 belong to Barina; 717 are described as new, with 81 new 
genera. 
The remaining groups of the Curculionine—the Acamptina, Trypetina, and 
Cossonina—are described in Vol. LV. part 7. The twenty-three plates belonging to 
Part 5, illustrating 720 species, are wholly or partly coloured. | 
26. Connoprera. Vol. IV. part 6: Brenthide by D. Sharp; Scolytide by WwW. X, 
H. Blandford ; Anthribide by K. Jordan. 
Three families of the Rhynchophora are enumerated in this Volume: the Brenthide, 
published in 1895,.by Dr. Sharp; the Scolytide, published in 1895-1905, by 
Mr. Blandford; and the Anthribide, published in 1906-1907, by Dr. Jordan. 
Part 6 was reserved for them in 1895, long before the Parts 4 and 5 were commenced, 
The general sequence of arrangement adopted in this work has therefore been 
interrupted by the interposition of these families in the present volume; the 
remainder of the Curculionine belonging to Part 5 were concluded in Part 7. The 
total number of species included in the three families is: Brenthide 140 (104 new), 
Scolytidee 272 (181 new), and Anthribide 193 (148 new). The Brenthide are mostly 
confined to the forests of the tropics, and are particularly numerous in Tropical 
America, Madagascar, and the Indo-Malay region. As regards the Scolytide the 
author, Mr. Blandford, remarks that the genera are either cosmopolitan or Neotropical, 
some of the latter being represented by stragglers in North America; he also says that 
the southward limit of many northern forms is doubtless determined by the distribution 
of the Conifer, which do not reach south of Nicaragua. . Dr. Jordan, in his intro- 
ductory remarks on the Anthribide (p. 299), writes as follows :—‘‘ The present 
treatise offers an illustration of the great increase in the number of known species 
when a tropical district has been more exhaustively examined. Hardly three dozen 
forms were known from Central America, while the material now before me comprises 
close on 200 species.” ‘These insects are rarely found in large numbers, owing to their 
ereat resemblance to the bark of trees on which they occur. The author divides the 
Anthribide into two ‘subfamilies, the Pleurocerine and the Anocerine, and gives a 
key to the whole of the genera (pp. 300-302). In the text the type of each genus is 
indicated, and the species of the larger genera are tabulated. 
Fourteen plates are issued with this volume: three for the Brenthide, six for 
the Scolytide, and five for the Anthribide, the last mentioned being coloured. 
27. Cotroptera. Vol. 1V. part 7: by G. C. Champion: Curculionide (concluded). 
This Volume finishes the Rhynchophora, the rest of the Curculionide belonging to 
the Subfamily Curculionine—the Groups Acamptina, Trypetina, and Cossonina—and
