1 66 FAUNA HAWAIIENSIS 



Apparently a very distinct species. The elytra are much more parallel-sided than 

 is usual in the genus (as in O. pulchrum, &c.), and are comparatively widely rounded at 

 the apex. The interstitial puncturation is very distinct, and the traces of striation are 

 very feeble even towards the apex. The metallic colouring is not very pronounced. 



Hab. Kauai, Halemanu. One example taken. 



(28) Oodemas purpurascens, sp. nov. 



Robustum, oblongo-ovatum, nitidum. Rostrum rugoso-punctatum, apice baud 

 dilatato. Antennarum articulus secundus brevis, tertius hoc multo longior. Pronotum 

 sat longum, subtiliter densius punctatum. Elytra nitida, metallescentia, parum distincte 

 striata, seriatim grossius foveolatim-punctata, interstitiis plus minusve, (nonnunquam 

 crebre), punctulatis. Tarsorum anticorum Z articulus tertius parvus. J $. Long. 



4— 5"25 mm. 



The head and thorax are black with little or no metallic colouring, the elytra are 

 very distinctly metallic, of a dark colour inclining to purple. The interstices are very 

 faintly, sometimes hardly perceptibly, convex, their puncturation in the single ^ is faintly 

 impressed and not conspicuous as in the two females examined, but of the latter one has 

 the interstitial puncturation considerably more strongly developed than the other. The 

 ^ is much smaller than either of the females. The species appears to be most nearly 

 allied to O. puncticolle, from which it differs in the colour, in its more robust form, 

 coarser punctures of the elytra, which are less vertical behind, and more pointed at the 

 apex, &c.

 elongatum, rugoso-punctatum. Antennarum articulus secundus (praecipue $) fortiter 

 elongatus, tertius hoc longior. Elytra grosse seriatim foveolato-punctata, interstitiis

Shining, elongate, oblong ovate, prothorax bronze-coloured, elytra bright metallic 

 green. Rostrum very short in the $, considerably longer in the female, rugosely punc- 

 tured. First joint of the funiculus of the antennae elongate, very strongly so in the ?, 

 the second joint generally still longer, but sometimes the two are nearly equal in length. 

 Prothorax shining, much narrowed in front, not very wide at the base. Elytra very 

 coarsely punctured, their surface brightly shining, the sides but little rounded, giving
