Actenodes flexicaulis, new species. 



Elongate, dull bronze to nearly black, underside metallic green or blue, cupreous 

 at sides. Antenna: metallic green to purple. Clypeus truncate, with a very feeble 

 tooth at middle, front very coarsely asperately punctured with the usual chevron-like 

 design. Thorax twice as wide as long, narrower at ape.x than at base, sides straight, 

 subbasal transverse impression strong ; punctuation denser at apex, punctures larger 

 and more sparsely paced at sides and base. Elytra a little wider than the thorax, 

 parallel nearly to the middle, slightly widening behind the middle and then arcuately 

 narrowing to apex, which is obtuse, side margins serrulate ; surface scabrous, costce 

 distinct at about apical half, stronger at apex ; base transversely impressed, the im- 

 pression metallic green, a strongly angulate irregular fascia at about basal third, an 

 oblique fascia slightly behind middle and a large spot between suture and first costa 

 metallic green and cupreous, the spot and the lower costa sometimes united by a nar- 

 row cupreous lines, sides at apical third narrowly margined with metallic green. Body 

 beneath shining, abdomen sparsely punctate, the punctures not deeply impressed. 

 Length 7. 50-10. 25 mm.

 mens in the Museum of the Brooklyn Institute. 



I have taken a small number of this fine species from branches 

 of Acacia flexicaulis, in which it undoubtedly breeds; no specimens 

 were taken on any other tree. 



The North American species of Actenodes now known may be 

 separated by the following table. 



Eyes on the occiput separated by about their own width. 



Robust unicolorous, elytra without costs, front convex not longitudinally impressed. 



lueiidax, Horn. 

 Eyes on the occiput narrowly separated by about half or less of their own width. 



Elytra not distinctly costate, or at most the costas indicated by smooth more or 

 less distinct lines, hind angles divergent, faintly in some specimens of 

 acornis. 

 Elytra unicolorous, without golden or metallic spots or fascise, front convex 



not longitudinally impressed acornis. Say. 



Elytra with suture, margin near apex, humeri and four spots on each side 

 metallic green or cupreous, front longitudinally impressed. 



auronotata^ Lap. & Gory. 

 Elytra with one strongly angulated, very indistinct, metallic green and 

 cupreous fascia before the middle and one behind, ending in a slight fovea 

 near side, basal depressions and suture at base metallic green ; front lon- 

 gitudinally impressed, costae faintly indicated calcaraia, Chev. 



Elytra distinctly costate in apical half, the costse distinctly raised and more promi- 

 nent towards apex, hind angles, or more properly the sides of thorax near base 

 convergent, elytra with a strongly angulated metallic green and cupreous fascia 

 before middle and an oblique one continued down the first costa for a short 

 distance and approaching the suture, front faintly \xivgixe.%?,&A.. flexicaulis, n. sp.
