probably to discoloration. At once distinguished from G. ceylonensis 

 by the much more transverse and finely punctured thorax as well as 

 by the uniform obscure, not metallic green, colour of the elytra. 



Galerucella crotchi, sp. nov. 



Obscure testaceous, finely pubescent ; the head with one, the 

 thorax with three fuscous spots ; elytra metallic green, finely rugose 

 and pubescent, the sutnral and lateral margin narrowly purpUsh. 



Length 2| lines. 



Head minutely punctured, with an indistinct central longitudinal 

 groove, the vertex with an obscure large fuscous spot. Antennae half 

 the length of the body, testaceous, the terminal joints stained with 

 fuscous, the third joint shorter than the fourth. Thorax twice as 

 broad as long, the sides rounded, narrowed at the base, surface 

 finely pubescent, with an obsolete transverse lateral and a deeper 

 longitudinal central depression, the sides and the central groove 

 fuscous. Scutellum fuscous. Elytra covered with rather long grey 

 pubescence, bright metallic green, narrowly margined with purplish, 

 the surface finely rugose-punctate. The tibiae unarmed, the first 

 joint of the posterior tarsi nearly as long as the two following joints 

 together. Claws bifid ; anterior coxal cavities open. 



Ga/eruca cenescens, Fairm., from Central China, seems to be closely 

 allied to the present species, but differs in the equal length of the 

 third and fourth joints of the antennas and in the traces of longi- 

 tudinal costse of the elytra, also in the different shape of the thorax. 



Galerucella marginata, sp. nov. 



Obscure testaceous ; antennae, tibiae, and tarsi black ; head and 

 thorax strongly punctured, shining, the thorax with five black spots ; 

 elytra very finely punctured and pubescent, obscure testaceous, a 

 narrow longitudinal stripe near the lateral margin blackish. 



Length 3| lines. 



Head closely rugose-punctate, the vertex obscure fuscous. Antennae 

 more than half the length of the bodj', black, slender, the third 

 joint the longest. Thorax more than twice as broad as long ; the 

 sides subaugulate at the middle, the anterior angles slightly dentate ; 

 the surface closely impressed with larger and smaller punctures, the 

 sides with a deep round fovea, the middle with an obscure longitudinal 

 depression, the latter of black colour, a similar-coloured spot is placed 

 close to the lateral margins, making in all five spots placed transversely 

 across the disk. Elytra rather convex, very finely and closely punc- 

 tured and covered -with short whitish pubescence ; a narrow lateral 

 stripe commences at the shoulder and is abbreviated a little distance 

 from the apex of each elytron ; the first joint of the posterior tarsi 

 as long as the two following joints ; claws bifid. 



A single specimen. 



Xenarthra mirabilis, sp. nov. (Plate XI. fig. 9.) 



Elongate, parallel ; subdepressed, testaceous ; antennae piceous, 

 pectinated, 12-jointed ; head with three, thorax with five piceous
