thorax with the sides margined, and the anterior angles, as a rule, 
somewhat produced; scutellum visible; tarsal claws appendiculate or 
armed with a tooth, which is very rarely absent.

GALERUCE. 
According to the Munich catalogue published in 1876, this division, 
or family as some authors regard it, contains about one hundred genera 
and eight hundred species ; since that time, however, about forty genera 
und upwards of five hundred species have been added, and the number 
is being constantly increased by the researches of Mr, Baly, Mr. 
Jacoby, and others ; a large proportion of the additions are due to Mr. 
Champion, who has shown us, by what he has done in Central America, 
what vast fields yet remain unexplored, and how much we may expect 
in the future from other districts of the world, if only equally energetic 
workers can be found to search them; the Galeruce are represented in 
Europe by thirteen genera and about one hundred and twenty species, 
most of which are somewhat obscure and not conspicuous insects ; of 
these only seventeen have hitherto been discovered in Britain ; in our 
catalogues they are usually assigned to only five genera, but I have 
adopted Lochmea, Weise, and Sermyla, Chapuis, as the species belonging 
to them appear to be distinct from those with which they have been 
classed. 
The larvee of the Galeruce are more elongate and linear than those of Chrysomela ; 
the mouth parts, according to Chapuis (Cat. des Larves des Coléoptéres, p. 274), 
resemble those of Crioceris, but the larve of the latter insect have six ocelli on each 
side of the head, whereas those of the present tribe have but one; the bifid process 
which terminates the anal segment of the abdomen in Timarcha and Chrysomela is 
here replaced by a simple and rather larger process; asa rule the larve are ofa dull 
colour, sometimes entirely black, and are covered with more or less numerous yellow 
hairs ; the dorsal segments are transversely furrowed and furnished with shining black 
plates or tubercles as in Melasoma 3 the larve bury themselves in the ground before 
assuming the pupal state. 
The larve of Adimonia tanaceti and Galeruca nymphea are figured by Westwood 
(Classification, i. p. 377, fig. 46, 21 and 15); the former is black and fleshy, and is 
less elongate than the latter, and has each segment furnished with several raised 
setose tubercles placed transversely ; the latter has the segments wrinkled, and is only 
furnished with lateral tubercles ; the larva of Agelastica alni is also figured (I. c. 
p. 383, p. 47, fig. 4); it is more elongate than is the case with the generality of the 
larve of this tribe, and according to Bouché it moves along like the caterpillars of the 
Geometridx.
