ITALIA , LONGITARSUS. 



333 



long and club-shaped, second thicker but shorter than third, 

 fourth shorter than third ; from the fifth the segments are thicker. 

 Prothorax much broader than long, sides straight, anterior lateral 

 angles thickened, basal margin forming a very wide arch, almost 

 straight; surface convex, smooth, shining, seen under a high 

 power to be extremely minutely and sparsely punctate. Scutellum 

 broader than long, triangular, with apex broadly rounded, surface 

 smooth, impunctate. Elytra closely, strongly, and confusedly 

 nunctate. Underside: posterior tibiae much longer than those of 

 the front and middle legs, somewhat bent, their outer edge with a 

 series of spinules, which are smaller and closer together near the 

 apical end than in the more proximal parts ; first segment of 

 posterior tarsi somewhat longer than the following two together. 

 Length, 2± mm.

Genotype: Chrysomela atriciUa, Linn. (Fauna Suec. 1761, 

 p. 166 ; Europe). In proposing the genus, Latreille cited several 

 species, from amongst which I select this species as the genotype. 



This genus is very large and includes a great variety of forms. 

 But in spite of this diversity the following characters are con- 

 stant in the genus : the insects are generally small ; the antennae 

 are fairly long and .slender, extending to beyond the middle of the 

 elytra, or even exceeding the length of the insect; the posterior 

 femora are well thickened; the posterior tibiae are long, graduallv 

 broadened, and flat above towards the apex, which ends in a 

 distinct, well-developed and sharp spine ; the portion of the hind 

 tibia? which is gradually broadened is not channelled on the outer 

 surface, although in some cases it may appear so owing to the 

 edges being dark ; the internal edge has a fringe of fine hairs and 

 the outer has equally a fringe and a series of spinules, more 



* Chapuis, Seudder, and Agassiz quote Latreille's ' Families Naturelles du 

 Begne animal ' (Paris, 1825, p. 405) as the work in which this genus was first 

 published ; but, although the genus is first mentioned there, it was not until 

 1829, in Ouviers ' Begne animal,' that a description (with the citation of 

 several species) of Longitarsus appeared.
