250 THE ENTOMOLOGIST. 



Lamprospluerus amazonicus, sp. nov. 



Dark fulvous ; the antennas (the basal joints excepted) and the 

 legs black ; thorax extremely finely and sparingly punctured ; elytra 

 remotely punctate-striate. Length, 4 mill. 



Oblong or subelongate ; the head impunctate, fulvous ; the clypeus 

 not separated from the face, entirely impunctate, its anterior margin 

 concave at the middle ; antennas extending below the middle of the 

 elytra, black, the lower three joints flavous, third and fourth joints 

 equal, the fifth slightly longer, terminal joints elongate and slightly 

 thickened ; thorax transversely convex, twice as broad as long, the 

 sides strongly rounded, with a narrow margin, the anterior angles 

 slightly thickened, the surface with a few extremely minute punctures, 

 only visible under a strong lens, posterior margin scarcely produced at 

 the middle ; elytra slightly wider at the base than the thorax, convex, 

 oblong, tbe shoulders prominent, distinctly but not very regularly 

 punctate-striate, the punctures as well as the rows distantly placed, 

 the suture not preceded by an impressed line, but by a row of closely 

 placed punctures ; sides of the elytra strongly deflexed so as not to be 

 visible from above ; legs nearly black, the anterior femora more or less 

 fulvous at the base ; prosternum oblong, rather broad, slightly narrowed 

 between the coxae. 



Hob. Amazons. 



This is another species of far more oblong shape than the 

 typical forms, but agreeing in the main points with Lamprosphcsrus. 



Lamprosphcerus flaveolus, sp. nov. 



Oblong-ovate, flavous ; the apical joints of the antennae black ; 

 thorax remotely punctured ; elytra with basal depression, strongly 

 punctate-striate, the punctures distantly placed. Length, 4 mill. 



More elongate in shape than the typical species of the genus, of 

 entirely flavous colour ; the head distinctly but remotely punctured, 

 the vertex with a central longitudinal groove ; the clypeus separated 

 from the face by a transverse depression, remotely but strongly punc- 

 tured ; eyes large ; the antennae extending to the middle of the elytra, 

 flavous, the fifth and the following four joints fuscous, the apical two 

 flavous again, third and fourth joints equal ; thorax more than twice 

 as broad as long, of equal width, the sides strongly rounded, with a 

 narrow reflexed margin ; elytra oblong, depressed below the base, the 

 surface remotely punctate-striate, the punctures distantly placed, a 

 short row of closely placed punctures is placed near the suture at the 

 base, followed by an impressed or punctured groove which accompanies 

 the suture, the apex of the elytra less strongly punctured than the rest 

 of the surface ; elytral epipleurae moderately broad at the base, flat ; 

 prosternum subquadrate, longer than broad. 



Hob. Amazons. 



I have retained the name for this species given to it by the 

 late Ed. Lefevre, who examined the insect. The latter is by no 

 means a typical representative of the genus, as the general shape 

 is not ovate or rounded, nor is the prosternum broader than long.
