EUDOLIA.

towards the base ; in front of the basal line is a transverse 

 depression, often interrupted in the middle and containing a few 

 rather large punctures. Scutellum smooth, impuuctate. Elytra 

 •elongate, par;illel-sided, broadly rounded at apex ; surface punc- 

 tate, the puncl ures being arranged in closely-placed longitudinal 

 rows, but the arrangement is not sufficiently regular for the rows 

 to be definitely counted ; on the convex basal and the apical part- 

 the punctures are feeble and sparse, while they are strong and 

 closely placed in the middle. Underside smooth, impuuctate, 

 sparsely covered with fine white hairs. 

 Length, 4|-5 mm.

Type in the British Museum. Described from five examples. 



139. Eudolia ratula *, sp. nov. 



Head, prothorax, and basal segments of antennae red-brown ; 

 apical segments of antennae piceous ; front and middle legs lighter 

 brown : hind legs often very dark brown, but they may be as 

 light as the other legs ; underside black. The basal segments of 

 the antennae, the prothorax, and the legs may vary from quite a 

 light to a deeper brown. The colour of the elytra is never a 

 pure blue and varies to a shade which has a large admixture of 

 violet. 



In all essential features this species resembles the preceding 

 two. The basal segments of the antennae present a certain 

 amount of variation in their relative lengths, especially the second, 

 third and fourth; the second is sometimes quite small as compared 

 with the third and sometimes not so, in the latter case the third is 

 shorter than usual ; similarly, the third may be either distinctly 

 longer than, or almost equal to, the fourth ; the fifth and sixth 

 are considerably swollen in some cases, in others (males) they are 

 less swollen, but still distinctly more dilated than the preceding 

 segments. The variation in colour is described above. 



Length, 3-4 | mm.

This very variable insect may prove to be a form of the 

 preceding species and, further, ail the species of Eudolia from our 

 regions may be really one. They all occur in mountainous parts, 

 in the Himalayas or their eastern extensions. I also believe that 

 the males (taken by themselves, leaving the females out of account) 

 will show a dimorphism in the structure of the antenna?. But 

 the material before me is insufficient to establish these points.
