tion of the anteanse. But, in addition to this, the shape of 

 the legs, the structure of the pronotum, and the form of the 

 pro- and mesosterna, together with other minor characters, all 

 point to the Eumolpin^ as the proper position for the genus. 

 The peculiar form of the intercoxal processes of the pro- and 

 mesosterna, which it possesses in common with Aalexis^ 

 il/e;air?/o???/cAa, and other EumolpinoBj has never been adequately- 

 described, though it could scarcely have escaped observation. 

 The prosternal process is rather strongly arched, and at about 

 the middle of its length is angularly dilated on each side, with 

 the angle fitting into a corresponding niche in the coxa; 

 behind this point it is slightly narrowed, and then gradually 

 widens out behind. The mesosternal process is somewhat 

 similarly dilated between the middle of its length and the 

 hind border. This form of the sternal processes is all the 

 more important, inasmuch as, so far as I am aware, it nowhere 

 occurs in the Galerucina3. 



One of the chief characters of Aulexis is that the epistome 

 is emarginate in the middle of its anterior border and is 

 furnished with a tooth on each side which overlaps the 

 labrum. This character is even more pronounced in Gonio- 

 pleura. In other points of structure these two genera exhibit 

 the greatest resemblance, notwithstanding that the species of 

 Goniopleura average more than twice the size of those of 

 Aulexis. 



Up to the present only four species of Goniopleura have 

 been described ; and the last of these was probably founded 

 on female examples of the first. I have now to add to the 

 number the following new species : — 



Goniopleura hicoloripeSj sp. n. 



Rufo-testacea, dense punctata, griseo sat sparsim pubescens ; elytris 

 (parte quinta basali excepta) cyaneo- aut viridi-metallicis, tarsia, 

 tibiis, geaibus efc antennarum articulis octo distalibus, nigris. 

 Elytris maris setis griseo-fulvis, longissimis, erectis, sparsim 

 hirsutis. 



Long. 14-15 mm.

This species resembles G. auricoma, Westw., but may be 

 easily distinguished by the narrower reddish area at the base 

 of the elytra, and by the colour of the legs and antennte, 

 which in auricoma are entirely testaceous. In both species 

 the males only have tlie elytra furnished with very long and 

 erect pale tawny hairs; in the females the elytra have a 

 shorter greyish pubescence. This sexual difference does not
