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 Timarcha 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 

 (I.e. 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 

 (I.e. p. 303), he separates off one of the larger divisions of the latter 

 tribe (containing Phcedon, Hydrothassa, and Prasocuris) as having the 

 tarsi with the third joint " apice evidenter sinuato, bilobo," whereas the 

 division containing Plagiodera and Melasoma is said by him to have the 

 third joint " apice obsolete vel haud sinuato ; " when, however (I.e. 

 p. 552), he is discussing the characters of Melasoma (Lino), 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 antennae 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 as a 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 Phytophnga, is com-
