ampliato, liniboque inflexo uigrls; pectore medio abdo- 

 minisqiie basi piceis. 



Long. 1^ lin. 



Hub. — Amazons, Para. 



Head trigonate, strongly punctured, face impressed 

 between the eyes with a longitudinal groove; clypeus 

 wedge-shaped, its apex acute, its anterior margin sinuate ; 

 antennae four-fifths the length of the body, slender, fili- 

 form. Thorax more than twice as broad as long; sides 

 rounded and converging from base to apex, the anterior 

 angles acute ; above transversely convex, deeply but not 

 closely punctured. Scutellum semiovate, its apex acute. 

 Elytra broader than the thorax, narrowed towards the 

 apex, convex, rather strongly punctate-striate, the striae 

 not well-defined on the anterior disk, arranged in double 

 rows behind the middle, but forming only single rows at 

 the extreme apex. Apices of hinder tibi^ incurved in 

 the $. 



Colaspoides dorsata. 



Late ovata, valde convexa, sordide fulva, nitida, thorace 

 subremote sat fortiter punctato ; elytris fortiter seriatim 

 punctatis, plaga magna communi a basi fere ad apicem 

 extensa, utrinque emarginata, picea instructis. 



Var. A. Elytrorum plaga plus minusve obsoleta. 



Long. 1^ lin. 



Hab. — Amazons, Para. 



Head finely but distinctly punctured, impressed on 

 either side above the eye wdth a few fine striga? ; clypeus 

 trigonate, its anterior margin truncate ; eyes black ; 

 antenna? filiform, pale fulvous. Thorax twice as broad as 

 long ; sides rounded and converging from base to apex, 

 all the angles acute ; disk strongly but not closely im- 

 pressed with oblong punctures, interspaces sparingly 

 impressed with very minute punctures, only visible under 

 a strong lens. Scutellum semirotundate, its apex acute. 

 Elytra convex, broader and more strongly punctured than 

 the thorax, the punctures arranged in ill-defined longitu- 

 dinal rows ; interspaces plane ; the piceous patch on the 

 dorsal surface is often less distinct, being sometimes sepa- 

 rated in four ill-defined spots, two on each elytron, and 

 sometimes nearly obsolete ; in some specimens the lateral 

 margin of the elytron is edged with piceous. 



This insect closely i*esembles in general form and size 

 the species belonging to the genus Lamjirosphoerus.
