Rah. Colombia (PchlJce), Mus. Stettin and ray collection. 



The general colour of this species is a very dark, almost 

 blackish-green a?ncous, in which it resembles C. strigosa, 

 Lef., and several other species, it is however of rather 

 small size, the antennae and legs are likewise dark, and 

 the elytral punctuation is distinctly geminate near the 

 suture, the interstices however are only costate near the 

 apex. There seems to be no difference of importance 

 between the sexes. 



Colaspis ainabilis, sp. n. 



Metallic green, tlie basal joints of the antennfe and the legs pale 

 fulvous, thorax closely and finely punctured, anguhite at the sides, 

 elytra finely semi-geminate punctate near tlie suture, more strongly 

 and irregularly so at the sides, the interstices at the latter place 

 transversely rugose. 



Length 5 millim. 



Mas. Head rather closely punctured, metallic green with purplish 

 or cupreous stains, the space between the eyes with a deep transverse 

 groove, clypeus triangular, closely punctured, labrum ol)scui'e fulvous, 

 palpi flavous, the apical joint piceous, antenna; piceoiis, the Ijasal 

 four or five joints fulvous below, the first joint metallic green above ; 

 thorax with the sides angulate at the middle, the anterit-r angles 

 thickened and tu]:)erculate, the disc punctured like the thorax, the 

 punctures rather fine but deep and closely placed, the interstices 

 scarcely raised ; elytra with a transverse depression below the base, 

 the punctures near the suture not stronger than those of the thorax 

 and placed in not very distinct double rows, but singly near the 

 apex, those at the sides much stronger and more irregularly placed, the 

 interstices transversely rugose at the same place ; legs fulvous, the 

 posterif)r femora with a more or less metallic green gloss, the extreme 

 apex of the tibiio and the tarsi piceous. 



Hah. Bolivia. 



One of the smaller-sized species and principally distin- 

 guished by the rather evenly and not very strongly 

 punctured tliorax with the interstices not raised, also by 

 the smooth appearance of the elytra near the suture, where 

 the punctures are fine and placed in double rows. C. 

 gciiiculata, Lef., has a widely punctured thorax and 

 rounded or semi-rounded lateral margins according to the 

 description, the knees are also described as piceous and 

 the colour of the upper surface as bright cuppeous. C.
