SOUTH AMERICAN PHYTOPHAGOUS COLEOPTERA. 271 



broad as long, rather strongly narrowed in front, the sides rounded, 

 the angles acute, the surface finely but not closely punctured, the sides 

 more closely punctate, impunctate near the margins ; elytra not de- 

 pressed below the base, finely punctate-striate in irregular double rows, 

 which become single towards the apex, where the punctures are much 

 finer and the interstices slightly convex, at the sides the latter are 

 much more strongly costate in some specimens than in others ; below 

 and the legs black, with a more or less aeneous gloss. 



Hob. Bolivia. 



I cannot identify this species with N. atra, Har., the only one 

 with which it may be confounded. N. atra has evidently been 

 described from female specimens only, having an elytral tubercle ; 

 the size is larger, the punctuation of the thorax is described as 

 being more remote at the sides than at the middle, the exact 

 opposite being the case in N. boliviana. The elytra, according to 

 Harold, are very obsoletely punctate-striate at the base, but dis- 

 tinctly so near the apex ; in the present species this is again 

 exactly reversed. There are nearly a dozen specimens before me 

 which, although varying slightly in the strength of the punctua- 

 tion, agree in every other way ; amongst them is only a single 

 female specimen which has the elytral punctuation much finer, 

 and a single tubercle of very small size placed at the sides below 

 the shoulders. 



Nodonota fastitida, sp. nov. 



Dark blue or violet ; the labrum, palpi, antennae, and the tibiae and 

 tarsi more or less fulvous ; thorax extremely finely and closely punc- 

 tured ; elytra strongly and rather closely punctate-striate, feebly im- 

 pressed below the base. Length, 2£ mill. 



Head very finely and sparingly punctured, shining, the clypeus 

 more strongly punctured, separated from the face ; labrum and 

 antennae fulvous, the apical joints of the latter rather darker; thorax 

 twice as broad as long, the sides rather strongly rounded at the middle, 

 obliquely narrowed anteriorly, with a narrow reflexed margin, the 

 anterior angles acute but not dentiform, the surface extremely finely 

 and closely punctured tbroughout ; elytra subcylindrical, feebly trans- 

 versely depressed below the base, the punctuation comparatively strong 

 and arranged in single rather closely approached rows, the punctures 

 themselves, however, distantly placed, the interstices flat througbout ; 

 below and the legs greenish, the tarsi more or less fulvous. 



Hab. Peru. 



Of this species two specimens are contained in my collection, 

 one of them named as above by Lefevre, but evidently never 

 described ; whether the two specimens are, however, specifically 

 identical, I am doubtful, as one of them is more remotely and 

 strongly punctured on the thorax, and has the tibiae of fulvous 

 colour, and the upper side violaceous. Other differences I am 

 unable to find.
