the length of the body, five outer joints slightly thickened, 

 pale piceoiis. Thorax more than one-half broader than 

 long ; sides moderately rounded, faintly bisinuate, anterior 

 angles obtuse, hinder angles distinct, acute ; medial lobe 

 slightly produced, obtuse ; upper surface transversely con- 

 vex ; disk strongly but subremotely punctured ; basal 

 groove deeply impressed. Elytra broader than the thorax ; 

 sides parallel, apex regularly rounded ; above convex, not 

 excavated beloAv the basilar space, strongly punctate- 

 striate ; interspaces on the outer disk and towards the apex 

 thickened; the metallic green colour sometimes tinged 

 with blue ; under surfaces of head and thorax, together 

 with the legs, pale fulvous ; breast and abdomen piceous. 



Trichaltica elegantula. 



Subelongata, convexa, nigro-picea, nitida, capite (an- 

 tennis extrorsum exceptis), thorace minus fortiter impresso 

 pedibusque rufo-fidvis ; elytris setosis, metallico-viridibus,

Long. 1 — 1^ lin. 



Hab. — Brazil. 



Vertex impressed, as well as the inner borders of the 

 eyes, vnih. large round fovete ; encarpas subtrigonate, con- 

 tiguous at the inner angle ; carina narrowed ; antenna? 

 scarcely half the length of the body ; six outer joints 

 slightly thickened, pitchy black ; eyes black. Thorax 

 nearly one-half as broad again as long ; sides straight and 

 slightly diverging from the base to beyond the middle, 

 thence rounded and converging to the apex, anterior 

 angles very obliquely truncate ; lateral margin irregularly 

 crenate ; basal margin nearly straight, the medial lobe not 

 produced ; upper surface remotely punctured ; basal groove 

 deeply impressed, divided in the middle by a longitudinal 

 ridge. Elytra broader than the thorax, oblong, convex, 

 not excavated below the basdar space ; strongly punctate- 

 striate ; interspaces slightly thickened on the outer disk 

 and towards the apex. 



Nearly allied in form and colouration to T. amazona, 

 differing from that insect in the form and sculpturing of 

 the thorax.
