Hab. — Amazons ; collected by Mr. Bates. 



Head short, rather coarsely punctured, front broad; 

 eyes distant, bordered above Avith a sunken orbit ; clypeus 

 transverse, obliquely inflexed, pentangular, its anterior 

 margin subangulate-emarginate ; antenna3 rather more 

 than half the length of the body, robust, the six outer 

 joints thickened, compressed and dilated, gradually in- 

 creasing in width from the sixth to the tenth ; the eleventh 

 rather narrower than the tenth, ovate, its apex angulate, 

 acute; five lower joints fulvous, the six outer ones black; 

 labrum fulvous. Thorax twice as broad as long ; sides 

 straight and parallel from the base to the middle, thence 

 obliquely rounded and converging to the apex, the hinder 

 angles posteriorly produced, very acute; basal margin 

 deeply concave on either side, the medial portion broadly 

 rounded; disk transversely convex, obliquely deflexed on 

 either side at the apex ; surface impressed with deep 

 round punctures, scattered over the disk, rather crowded 

 on tlie sides, interspaces sparingly impressed with very mi- 

 nute punctures. Scutellum semirotundate-ovate. Elytra 

 very slightly broader at the base than the thorax, slightly 

 attenuated towards the apex, oblong-ovate, convex, not 

 depressed below the base, deeply but not very closely 

 l)unctured, the punctures indistinctly arranged in longi- 

 tudinal strife, which become much more defined at the 

 apex; interspaces very finely punctured, plane, obsoletely 

 convex between the apical stria3. Body beneath rufo-ful- 

 vous, more or less stained with piceous; thighs thickened. 



Chrysodina nigrita. 



Ovata, convexa, nigra, nitida, antennis basi rufo-piceis, 

 thorace fortiter, remote punctato ; elytris thorace latiori- 

 bus, fortiter seriatim puuctatis, interspatiis planis, impunc- 

 tatis.
