l^aly, has likewise similariy coloured legs, but the elytra 

 are of a differeut colour, and have eight costa3 (presumably 

 in the female). 



Ghalcophana erichsoni, sp. n. 



Black, with a slight bluish tint, the basal joints of the antennae 

 and the labrum fulvous, thorax witli a few fine punctures, elytra 

 reddish-brown, closely punctate-striate, the interstices at the sides 

 costate. 



Length 10 millim. 



Fern. Head with a deep, central groove, finely strigose, clypeus 

 elongate, wedge-shaped, scarcely punctured, labruni fulvous, antennte 

 black, the lower three joints fulvous (the last two joints wanting), 

 fourtli joint distinctly longer than the third ; thorax scarcely 

 twice as broad as long, narrowed anteriorly, the sides moderately 

 rounded, the anterior angles produced, the surface with a few fine 

 punctures and some very fine longitudinal strigse near the base, 

 bluish-black, scutellum black ; elytra elongate, with a transverse 

 dejiression below the base, reddish-brown, rather strongly and closely 

 punctured, the punctures much finer towards the apex, sometimes 

 slightly arranged in double or treble rows, the interstices at the sides 

 below the base raised into short costse to the number of three, the 

 shoulders prominent and followed by a more pronounced costa 

 extending nearly to the apex at which place it is very strongly 

 raised, the lateral margin likewise strongly and acutely costiform ; 

 below and the legs black, very shining, with a slight bluisli lustre, 

 impunctate. 



Hah. Peru. 



I cannot identify this species, of which I only know the 

 female, with G. coii&jjicua of Lefevre, who describes his insect 

 (likewise from Peru) as having the abdomen " cyaneum," 

 the breast, head and thorax as " nigro-seneis " and the tarsi 

 as "rufis"; the author also describes the elytra as geminate 

 punctate, and mentions two costse only below the shoulders ; 

 in other respects the two insects seem very much alike. 



Ghalcophana picta, sp. n. 



Fem. Fulvous, the head, antenna?, the breast and the tibite and 

 tarsi black, thorax minutely punctured, subangulite at the sides, 

 elytra closely and more strongly punctured, fulvous, two elongate 

 stripes (one humeral, the other lateral) and a transverse irregular 

 band at the apex, including a fulvous spot, black.
