COLEOPTERA 157 



(5) Oodcmas costatiim, sp. nov. 



Ovatum, robustum, nitide aeneum. Rostrum nitidum, subtiliter punctatum, apice 

 subdilatato. Antennarum articulus secundus et tertius fortissime elongati, fere aequi- 

 longi. Elytra seriatim punctata, interstitiis punctulatis, a basi usque ad apicem elytrorum 

 distinctissime costatis. Tarsorum antic, et intermed. (j) articulus secundus maximus, 

 articulo tertio baud minus latus. ^. Long. 5 '5 mm. 



Ovate, shining, bronzy black. Rostrum shining, finely punctured, dilated at the 

 apex. Eyes convex, subprominent. Antennae with the first two joints of the funiculus 

 very long, subequal. Prothorax shining finely and feebly punctured. Elytra striate, 

 the striae strongly punctured, the interstices sharply raised from base to apex, giving 

 the elytra a ribbed appearance, and finely punctured. Second joint of the anterior and 

 intermediate tarsi of the ^ very large, about as wide as the apical width of the lobate 

 third joint, and rather longer than wide. 



Hab. Kauai Mountains (4000 ft.). A very distinct species, of which only a 

 single $ was taken. 



(6) Oodemas longicorne, sp. nov. 



Ovatum, robustum, aeneum, nitidissimum. Rostrum sat longum, apice dilatato, 

 nitidum, subtiliter dense punctatum. Antennae longae, funiculi articulo primo fortiter 

 elongato, secundo hoc vel longiore. Prothorax latus, nitidus, subtiliter punctatus. 

 Tarsorum articulus secundus anticorum et intermediorum aeque latus ac tertius, et 

 hoc multo longior. Elytra grossius seriatim antice punctata, interstitiis obscure costato- 

 elevatis. Z- Long. 5 mm. 



This species is closely allied to O. costahtm, but is very distinct by the sculpture 

 of the elytra, the interstices only showing a faint tendency to the costate form of that 

 species. 



Hab. Kauai. Four examples (all $), taken on the high plateau. 



(7) Oodemas ptinctulatissimtim , sp. nov. 



Nigroaeneum, nitidum, ovale, robustum. Antennae testaceae, graciles, sat elon- 

 gatae, articulo secundo brevi, tertio minus fortiter elongato, sed .secundo longiore. 

 Rostrum nitidum, apice dilatato, fortiter deflexo, subtilissime punctatum. Oculi parum 

 prominentes. Prothorax latus, nitidus, subtilissime (vix evidenter) punctatus. Elytra 

 nitida, antice vix evidenter, postice paullo distinctius, striata, dense punctulata, apice 

 fere recurvo. Pedes rufotestacei ; tarsorum {$) anticorum et intermediorum articulus
