Head coarsely and closely rugose, the penultimate joint of the palpi incrassate, 

 piceous ; antenna; more than half the length of the body, black, the third joint much 

 longer than the first, and the longest, the following gradually reduced in length ; 

 thorax about one-half broader than long, narrowed at the base, sub-angulato before 

 the middle, the angles acute, the surface rugose like the head, with two rather deep 

 basal depressions, divided by a raised longitudinal space, the disc impubescent, rufous ; 

 scutellura fulvous, broad ; elytra with a slight transverse basal depression, the space 

 surrounding the scutellum raised, of a bright metallic greenish-blue colour, mode- 

 rately strongly punctate-striate, the punctures more deeply impressed at the anterior 

 portion, the interstices irregularly and rather obscurely wrinkled, with a few stifE

Peribleptus ecuadoeiensis, n. sp. 



Fulvous ; the antenna;, anterior legs and the posterior tibise, black ; head nearly 



smooth ; thorax rugosely punctured ; elytra dark violaceous, finely punctate-striate. 



Length, 3 lines. 



Head with a few fine punctures ; antennae as in the preceding species ; thorax 



twice as broad as long, the sides obtusely angulated before the middle, the surface 



finely rugose, sparingly clothed with fulvous pubescence, obsoletely depressed at the 



base ; scutellum fulvous ; elytra without basal depression, finely punctate-striate, 



the interstices finely rugose ; impubescent ; below fulvous, the apical portion of 



the femora and all the tibiae and tarsi, black ; claws bifid. 



Hah. : Ecuador {BucTcley). 



P. ecuadoriensis is closely allied to P. metalllcus, but differs in 

 the nearly smootli bead, tbe more transverse tborax, tbe want of an 

 elytral depression, and tbeir dark violaceous colour. I possess a single 

 specimen. 



OCTOGONOTES APICICORNIS, n. sp. 



Broadly ovate, moderately convex, entirely pale fuscous, pubescent ; the terminal 

 four joints of the antennfe black ; thorax rugosely punctured ; elytra deeply punctate- 

 striate, the interstices convex, covered with short golden pubescence. 



Length, 3 lines. 



Head finely rugose, fovcolate between the antennae, the space below the latter 

 deeply transversely depressed, labrum fulvous with four deep punctures placed 

 transversely, apex of jaws black ; antennae half the length of the body, fulvous, the 

 four last joints black, thickened and shorter, the thii'd and fourth joints equal ; 

 thorax transverse, the sides sub-angulate before the middle, the anterior angles pro- 

 duced, the disc with a distinct semicircular depression near the base, closely and 

 finely rugose throughout, not pubescent ; scutellum triangular ; elytra broad with a 

 very obsolete post-basal depression, the punctures deep except near the apex, the 

 interstices rather distinctly longitudinally convex, clothed with very short golden 

 pubescence ; the apex of the posterior tibiae bimucronate ; claws appendiculate, the 

 inner division rather long.
