South American Eumolpidie. 4G7 



Var. Metallic blue, the legs piceous. 



Length 4 millim. 



Mas. Head remotely and strongly punctured, with a short central 

 longitudinal groove, the epistoine subrugose punctate, its anterior 

 portion rather strongly widened and deflexed, antennaj extending 

 to the middle of the elytra, black, the lower four joints and the 

 base of the fifth fulvous, terminal joints thickened ; thorax twice 

 as broad as long, but little narrowed anteriorly, the sides rounded, 

 the angles acute, the surflice closely impressed with smaller and larger 

 punctures, which are more crowded at the sides than at the middle, 

 scutellum impunctate ; elytra more strongly punctured than the 

 thorax, with a distinct transverse depression below the base, the 

 punctures arranged in more or less distinct double rows, which near 

 the apex become single, the interstices below the shoulders thickened, 

 those below the middle at the sides raised into two or three short 

 costse ; legs fulvous, tarsi black. 



Hah. Bolivia. 



Of this species, five specimens, which all seem to be 

 females, are contained in my collection ; the subgeminate 

 elytral punctuation, their costate outer interstices and the 

 fulvous legs and black tarsi will help to distinguish the 

 species; of the blue variety one specimen is before me 

 which does not differ except in coloration. 



Aghalus strigicollis, sp. n. 



Below obscure ajneous, above purplish or metallic blue, basal 

 joints of the antennae fulvous, thorax extremely finely and closely 

 punctured, the sides finely strigose, elytra finely and very closely 

 punctate-striate. 



Mas. The posterior tilji* with a short pubescent tooth near the 

 apex. 



Length 5 millim. 



Head very closely punctured, the vertex finely longitudinally 

 strigose, clypeus separated from the face by fine oblique grooves, 

 punctured like the head, labrum and palpi fulvous, antenna3 extend- 

 ing beyond the base of the elytra, fulvous, the apical four joints 

 black, distinctly thickened ; thorax proportionately long, scarcely 

 twice broader than long, the sides feebly rounded, with a narrow 

 reflexed margin, the anterior angles produced but not pointed, the 

 disc transversely convex, very finely and closely punctured, the 

 sides with some fine strigie, the interstices with still more fine 

 punctures, scutellum broader than long, with a few punctures ;
