tioii of tlie antennffi. But, in addition to this, the shape of 

 the lei^s, tlic structure of the pronotum, and tiie form of the 

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

 point to the Eumolpiiuu as tiie proper position for tiie genus. 

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

 mesosterna, which it possesses in comraon with Aulexis^ 

 JI/f?aj'7/07/?/c^^7, and other Eumolpinffi, has never been adequately 

 described, though it could scarcely have escaped observation. 

 The j)rosternal process is rather strongly arched, an<l 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. Tiiis form of the sternal processes is all the 

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

 occurs in the Galerucinaj. 



One of the chief characters of Aulexis is that the epistorae 

 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 iirst. I have now to add to the 

 number the following new species : — 



Goniopleura hicoloripeSy sp. n. 



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

 (parte quinta basali oxcepta) cyaneo- aut viridi-metallicis, tarsis, 

 tibiis, genibus et antennarum articulis octo distalibus, nigris. 

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

 hirsutid. 



Long. 14-15 mm.

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

 easily distinguished by thi; narrower reddish area at the base 

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

 which in auricoma are entirely testaceous. In both species 

 the males only have the 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
