164 THE ENTOMOLOGIST. 



elytra more strongly punctured in semi-regular rows, the last inter- 

 stice costate. Length, 5 mill. 



Head rather strongly but not closely punctured ; the epistome not 

 separated from the face, its anterior margin very slightly concave ; 

 labrum black ; antenna? extending to the base of the thorax, black, the 

 lower five joints fulvous, the basal joint stained with piceous above, 

 terminal joints broader than long ; thorax twice as broad as long, the 

 sides strongly and obliquely narrowed in front, the surface finely but 

 not very closely punctured, the interstices sparingly and still more 

 finely punctate, the base scarcely produced at the middle, the basal 

 margin with a row of stronger punctures ; scutellum much broader 

 than long ; elytra with a short but distinct transverse depression below 

 the base, the sides narrowly marginate, the surface rather strongly 

 punctured in somewhat close rows, the outer interstice costate from 

 below the shoulders to the apex ; under side dark blue, nearly im- 

 punctate ; tarsi blackish ; prosternum longer than broad, rugose, and 

 pubescent. 



Hab. Paraguay. 



One of the larger-sized species, which may be known by the 

 blue under and green upper surface, the colour of the antennae, 

 and their very broad terminal joints. 



Chrysodina jicruana, n. sp. 



Violaceous, above metallic cupreous ; head and thorax very finely 

 and closely punctured ; elytra more strongly punctate, the punctures 

 arranged in rows, the last interstice at the side costate near the apex. 

 Length, 6 mill. 



Head extremely minutely granulate, rather closely and strongly 

 punctured ; the clypeus not separated from the face, subquadrate ; 

 palpi stained with metallic green ; antennas black, the lower four joints 

 fulvous below, metallic greenish above, terminal joints very strongly 

 transverse, much broader than long, extending beyond the base of the 

 thorax ; the latter twice as broad as long, of the usual shape, the 

 punctuation fine and close, with still smaller punctures at the inter- 

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

 elytra punctate-striate, the punctures stronger than those of the 

 thorax, each elytron with about fifteen or sixteen rows, somewhat 

 unevenly placed, the last interstice strongly costate below the middle ; 

 under side and legs violaceous blue, nearly impunctate ; tarsi piceous. 



Hob. Peru. 



Of larger size, but similar coloration as C. fulgurans, Har. ; 

 the terminal joints of the antennae much broader than in that 

 species and of different colour, the punctuation of the thorax 

 liner and closer. 



Deutcrocampta optica, n. sp. 



Greenish black ; head and thorax greenish aeneous, opaque, spar- 

 ingly punctured ; elytra obscure fulvous, opaque, distinctly punctate- 

 striate. Length, 10 mill. 



Head greenish, opaque, with a few fine punctures ; the anterior 

 margin of the clypeus straight ; antennae black, the basal two joints
