Length 5-6 millini. 



Mas. Head finely and rather closely punctured, the clypeus 

 transverse, more strongly punctured than the vertex, antenna3 

 extending to the middle of the elytra, fulvous, the third joint slightly 

 shorter than the fourth ; thorax twice as broad as long, the sides 

 strongly rounded, suljangulate in the female, very obscurely so in 

 the male, with a distinct reflexed margin in both sexes, the surface 

 very finely and closely punctured, with an obsolete depression at 

 the sides ; scutellum broader than long ; elytra scarcely perceptibly 

 depressed below the base, rather strongly and regularly punctured, 

 the interstices slightly rugose, obsoletely costate near the apex ; 

 prosternum slightly narrowed at the middle. 



Hah. Brazil. 



Of this species, three specimens are contained in my 

 collection ; the female is of larger size, with the thorax 

 more transverse and the reflexed margins broader and the 

 angulation at the sides more marked. The species might 

 perhaps equally well find its place in Mhabdopterics had 

 it not been for the structure of the thorax. No other 

 species of Hermesia described w^ to the present is of 

 similar coloration. The exact locality is unknown to me. 



Alethaxius angulicolUs, sp. n. 



Obscure aeneous, the basal joints of the antenna3 fulvous, thorax 

 finely and subremotely punctured, the sides angulate below the 

 middle, elytra finely punctate-striate, the interstices costate at the 

 extreme apex. 



Fe.Mi. The elytra finely geminate-jninctate, the base with three 

 elongate tubercles. 



Length 4-5 millim. 



Head closely and rather strongly punctured, the clypeus not 

 separated from the face, emarginate at its anterior edge, labrum 

 seneous, palpi fulvous, the last joint piceous, antennae short and 

 robust, the terminal joints strongly thickened, more or less piceous, 

 the basal five joints fulvous, the fourth and the following two 

 joints of equal length, the third slightly shorter ; thorax twice as 

 broad as long, the sides obliquely narrowed anteriorly, angulate 

 below the middle, the anterior margin produced at the middle, 

 much shorter than the posterior one, the angles mucronate, the 

 surface very finely and sparingly punctured at the disc, more 

 strongly and closely so at the sides, scutellum broader than long, 

 im punctate ; elytra not wider at the base than the thorax, with a
