1 64 FAUNA HAWAIIENSIS 



elytra are black, with a copper-coloured metallic tint. The second joint of the anterior 

 tarsi is small, the lobes of the following joint rather large. In the other example, both 

 thorax and elytra are of a very marked copper colour, the former is rather longer, and 

 the sides of the latter less strongly rounded. 



Hab. Oahu. Mountains near Honolulu (3000 ft.) ; two examples taken. 



(23) Oodemas leiothorax, sp. nov. 



Nigroaeneum, nitidum, ovale. Rostrum c/ breve, ? sat longum, apice baud dilatato, 

 distincte punctatum. Antennarum articulus secundus elongatus, tertio paullo {i) vel 

 multo (?) longior. Pronotum nitidum, subtilissime (vix evidenter) punctatum. Elytra 

 nitida, levissime (vix evidenter) striata, striis subtilissime remote punctatis. Tarsorum 

 anticorum c/* articulus secundus brevis, subrotundus, tertius lobis parvis. Z%- Long. 

 3-5 mm. (Plate VIII. fig. 17). 



Apparently a very distinct species, by its antennae, the very feeble puncturation of 

 the thorax, and the delicacy of the series of punctures on the elytra. The metallic tint 

 of the latter is bronze-coloured and very distinct. 



Hab. Kauai. High plateau ; 2 ^, i ? taken. 



(24) Oodanas fiexirostre, sp. nov. 



Ovale, nigroaeneum, nitidum. Rostrum fortiter punctatum, ante medium fortius 

 decurvatum, apice baud dilatato. Antennarum articulus secundus et tertius subaequi- 

 longi. Pronotum nitidum, sat distincte punctatum. Elytra nitida, levissime striata, 

 striis remote parum fortiter punctatis, interstitiis subtiliter, nee dense, punctatis. Tarso- 

 rum anticorum lobi parvi. ^ (?). Long. 3-5 mm. 



Very similar to O. leiothorax in most respects, but distinguished by the more 

 strongly curved rostrum, the much more distinct puncturation of the prothorax, and the 

 less fine punctures of the elytra. 



Hab. Kauai (4000 ft.). One example. 



(25) Oodemas dubiosuni, sp, nov. 



Nigroaeneum, ovatum, elytris (j) subnitidis. Rostrum (saltern in media parte) 

 parce punctatum, apice haud dilatato. Antennae graciliores, articulo funiculi primo et 

 secundo subaequilongis [$), vel hoc longiore ($). Pronotum latum antice fortius angus- 

 tatum, subtiliter punctatum. Elytra striata, striis subfortiter punctatis, interstitiis dis- 

 tincte punctulatis. Tarsorum anticorum $ lobi parvi. Long, vix 4 — 4^5 mm.
