Galerucina.~\ HIYTOPHAGA. 321 



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. 

 The two tribes may be separated as follows: 



I. Posterior femora slender, not formed for leaping ; anterior coxae 



conical ly prominent at apex GALXRUCJB. 



II. Posterior femora thickened, formed for leaping ; anterior coxae not 



conical! y prominent at npex UALTICJ:. 



GALERUCJE. 



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 

 and 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 Galerucce 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 Lochm&a, Weise, and Sermyla, Chapuis, as the species belonging 

 to them appear to be distinct from those with which they have been 

 classed. 



The larvae of the Galerucee are more elongate and linear than those of Chrysomela ; 

 the mouth parts, according to Chapuis (Cat. des Larves des Coleopteres, p. 274), 

 resemble those of Criocerig, but the larvae 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 Chrytomela is 

 here replaced by a simple and rather larger process ; as a rule the larvae are of a 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 ; the larvae bury themselves in the ground before 

 assuming the pupal state. 



The larvae of Adimonia tanaceti and Oaleruca 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 (1. c. 

 p. 383, p. 47, fig. 4) ; it is more elongate than is the case with the generality of the 

 larva; of this tribe, and according to Douche 1 it moves along like the caterpillars of the 

 Geouietridae. 



I. Anterior coxal cavities open behind. 



i. Elytra without epipleurae PUYLLOBBOTICA, Rtdt. 



ii. Klytru with the epipleurte distinct, at least near 



shoulders.
