tarsi, or certain joints of the antenne dilated ; M. Allard remarks that 
he believes that in all the species, without exception, the males have a 
well-pronounced fovea on the posterior border of the last abdominal 
segment. 
In the Munich catalogue published in 1876 one hundred and forty 
genera and fourteen or fifteen hundred species are enumerated as belong- 
ing to the tribe; in M. Duvivier’s supplement, however, no less than 
forty-one new genera and nearly eight hundred species have been added, 
chiefly through the researches of Mr. Champion and the work of Mr. 
Baly and Mr. Jacoby; the members of the tribe appear to be widely 
distributed throughout the world; they are represented in Europe by 
about twenty-five genera and three hundred and seventy species, of which 
no fewer than twenty genera and about one hundred and seventeen 
species are found in Britain ; some of these are very closely allied and 
require great care in their identification, and this to a certain extent is also 
true of the genera; the tables, therefore, given below must be regarded 
rather as guides than as absolutely trustworthy, and must not be made 
use of without the detailed descriptions ; I have not made much use of 
the characters presented by the frontal tubercles and the under-side, as 
they are, in many cases, not very obvious ; the same, however, may with 
reason be said of many of the distinctions here employed, the basal trans- 
verse impressions of thorax, for instance, being sometimes more or less 
obsolete; for more detailed information regarding the group the student 
is referred to the Naturgesichte der Insecten Deutschlands, vol. vi. part 4, 
p. 666, by Weise, especially to his tables on pp. 674—678, and also to 
Allard’s ‘ Essai Monographique sur les Galerucites Anisopodes ” (Ann. 
Fr., Sept. 14, 1859) ; in many points I have preferred to follow Thomson 
(Skand. Col. x. 252).
