SOUTH AMERICAN CHRYSOMELIDJE. 165 



flavous below, terminal joints distinctly widened, scarcely longer than 

 broad ; thorax three times broader than long, the sides straight at 

 the base, moderately rounded in front, the anterior angles not mucro- 

 nate, the surface dull opaque greenish aeneous, very sparingly punc- 

 tured, the sides with some stronger punctures ; scutellum metallic 

 green ; elytra wider at the base than the thorax, regularly convex, 

 rather strongly and regularly punctate-striate, dull and opaque, fulvous, 

 the interstices entirely impunctate ; epipleurae, the under side, and legs 

 dark metallic greenish. 



Hah. Brasils. 



A species of very dull colouring, and somewhat silky appear- 

 ance, allied to D. ceneo-lucens, Stal, which is described as having 

 the elytra "testaceo-peilucidis," and a distinctly punctured 

 thorax. 



Deuterocampta (?) irregularis, n. sp. 



Black ; the head with a small fulvous spot ; thorax extremely 

 finely and sparingly punctured ; elytra fulvous, irregularly punctured 

 in double and treble rows ; terminal joint of the tarsi dentate. Length, 

 12-13 mill. 



Head with a few fine punctures, black, the vertex with a small 

 fulvous spot ; ultimate joint of the palpi testaceous at the apex; thorax 

 nearly three times broader than long, the sides straight and parallel at 

 the base, rounded near the anterior angles ; the latter rather produced, 

 the disc very sparingly and finely punctured, the sides with some 

 slightly larger punctures, black ; scutellum triangular, black ; elytra 

 rather wider at the base than the thorax, entirely fulvous, rather 

 strongly, closely, and irregularly punctured, the punctures here and 

 there arranged in rows, although very indistinctly so ; under side and 

 legd black, the sides of the breast nearly impunctate ; tibiae only 

 channelled near the apex, the claw-joint toothed at the apex ; claws 

 distant. 



Hab. Bolivia. 



This species scarcely fits into any of the groups of Stal's 

 arrangement, and differs from almost any of its allies in the 

 irregularly punctured elytra ; the prosternum, however, scarcely 

 differs from that of Deuterocampta, but the dentate claw-joint 

 agrees with Leptinotarsa, from which it again differs in the non- 

 sulcate tibiae. Two specimens are contained in my collection. 

 The species entirely resembles Doryphora semifulva, Jac, like- 

 wise from Bolivia, except in the structural characters. 



Deuterocampta crux nigra, Stal, var. bimaculata. 



Piceous ; the labrum, antennae, and the legs fulvous ; thorax finely 

 punctured, the disc blackish, the sides broadly flavous ; elytra finely 

 punctate-striate, flavous, the suture, the lateral margins posteriorly, 

 and a small round spot below the middle of each elytron greenish 

 black. Length, 11 mdl. 



Head finely and rather closely punctured, piceous, the vextex with 

 a fulvous spot ; the clypeus and the labrum fulvous ; antennae only
