CHRYSOMELINA. 
This tribe contains about seventy genera, of which eighteen occur in 
Europe; the most important in point of numbers are Chrysomela, 
Doryphora, and Paropsis; the two latter of these are not found in 
Europe, but Chrysomela appears to hold its own throughout the greater 
part of the world; next to this genus Z?marcha and Orina are the chief 
European genera ; the tribe is fairly represented in Britain by ten genera, 
but the number of species does not come up to this proportion, only forty 
being found out of two hundred and eighty which are inhabitants of 
Europe ; the characters of the tribe are hard to define with any certainty; 
it is closely allied to the Eumolpina, from which it chiefly differs in 
having the anterior coxal cavities transverse instead of round: Weise 
(Le. p. 276) gives as an additional character that the third tarsal joint 
is bilobed (zweilappig) in the Eumolpina, whereas it is entire or emar- 
ginate at the apex in the Chrysomelina ; in the table of genera, however 
(1.c. p. 303), he separates off one of the larger divisions of the latter 
tribe (containing Phedon, Hydrothassa, and Prasocuris) as having the 
tarsi with the third joint “ apice evidenter sinuato, bilobo,” whereas the 
division containing Plagiodeva and Melusoma is said by him to have the 
third joint “ apice obsolete vel haud sinuato;” when, however (l.c. 
p- 552), he is discussing the charaeters of Melasoma (Lina), he states that 
the third joint of the tarsi is bilobed (zweilappig) in half the German 
genera, and in the rest emarginate at apex. I have discussed this par- 
ticular point somewhat at length, as it shows that the characters of the 
whole group are very unsettled; as a matter of fact, nearly all the 
members of the tribe appear to be strongly bilobed, as the onychium 
arises from the neighbourhood of the base of the third joint which is 
usually deeply channelled ; the character therefore must be ascertained 
from below, and as the joints are often thickly pubescent it is in many 
cases hard to determine whether the lobes are divided or not; as a matter 
of fact this appears to be comparatively seldom the case among the 
Chrysomelina; the head is rather deeply sunk in the thorax and the eyes 
are entire ; the clypeus is subtruncate with the anterior margin trans- 
versely depressed ; the antenne are usually moniliform with the five or 
six last joints often somewhat thicker, and are inserted on the forehead 
behind the base of the mandibles ; the anterior coxal cavities are trans- 
verse, and asa rule, but not always, are open behind ; the thorax is 
closely applied to the elytra, and is usually as broad or nearly as broad 
as their base ; the abdomen, as in the rest of the Phytophaga, is com-
