the voyage of the ^ Novara/ Mayr describes in detail the new 
genera and species of Ilcteroptcra briefly characterized by him 
in the Verhandl. zooL-bot. Gescllsch. in Wien (see ^ Record/ 
1864, p. 575, and infra, p. 537), and adds a considerable number 
of valuable remarks on the general classification of these insects. 
A few new genera and species are described ; and most of the 
new genera established by Mayr are illustrated in the five plates 
accompanying the work. 
B. Separate Work. 
Stal, Carolus. Hemiptera Africana. Tom. ii. & iii., Stock- 
holm, 1865 ; & iv., ibid., 1866. 
These volumes contain the conclusion of StaTs descriptions 
of the Rhynchota of Africa, of which the first volume was 
noticed in last yearns ^ Record ^ (p. 686) . The analytical tables 
of genera throughout include the characters of many new genera 
from other parts of the world, of which no further notice is 
taken in this work ; the typical species are indicated or de- 
scribed in StaPs Analecta Hemipterologica,^^ published in the 
' Berliner entomologische Zeitschrift' for 1866, — a most incon- 
venient and reprehensible course of proceeding.
