COLEOPTERA 167 



the insect a more parallel-sided appearance than is usual in the genus ; the striae on the 

 apical portion of the elytra are very deeply impressed, so that the interstices are narrow, 

 strongly convex, and almost sharp. In the ^ the second joint of the front tarsi is small, 

 short and transverse, about half as wide as the bilobate third joint. 



Hab. Kauai (4000 ft.); rare. This is an extremely distinct species by its bright 

 metallic colour, its extremely coarse elytral punctures, and its general form. In the 

 latter respect the following species closely resembles it. 



(30) Oodcvias oblongum, sp. nov. 



Praecedenti affine, nigrum, nitidum, parum aenescens, oblongo-ovatum. Rostrum 

 opacum, rugoso-punctatum. Antennarum articulus tertius secundo longior. Pronotum 

 nitidum, subtiliter punctatum antice angustatum. Elytra seriatim fortiter punctata, 

 postice striis quam praecedentis minus fortiter impressis. J %. Long. 575 — 6'5 mm. 

 (Plate VIII. fig. 19.) 



Similar in form to the preceding, black, and only slightly aeneous. The great 

 difference in colour separates the two at once, as well as the finer puncturation of the 

 elytra of the present species, the punctures though less coarse being more definite in 

 form, and the striae towards the apex are less deeply impressed, the interstices conse- 

 quently standing out less sharply. The interstitial puncturation is fine, more or less 

 dense, and very distinct. 



Hab. Kauai (4000 ft.); rare. 



(31) Oodeiiias grande, sp. nov. 



Nigrum, robustum, ovatum, parum distincte aenescens. Antennarum articulus 

 secundus et tertius sat elongati, subaequales, vel hoc longiore. Rostrum rugoso- 

 punctatum. Pronotum latum, nitidum, subtiliter punctatum. Elytra nitida, seriatim et 

 confertim fortiter punctata, interstitiis dense et distinctissime punctulatis, postice haud 

 convexim elevatis, striis vix videndis. %. Long. 7 mm. (Plate VIII. fig. 20.) 



A large robust elongate-oval species, black, with a slight aeneous tint. The 

 rostrum is rugosely punctured, rather long in the ?, the sides nearly parallel, or slightly 

 converging from the base. The two basal joints of the funiculus are both long, sub- 

 equal, or the second the longer. The prothorax is very wide at the base, strongly 

 narrowed in front, the surface shining, finely but distinctly punctured. Elytra shining, 

 the striation excessively feeble even to the apex, the punctures of the series moderately 

 large and close, the interstices densely and conspicuously punctured. 



Hab. Kauai (4000ft.); 2 % taken. A very distinct species distinguished by its 

 large size, elongate basal joints of the funiculus, the rows of large punctures on the 

 elytra and dense and distinct interstitial puncturation.
