i6o FAUNA HAWAIIENSIS 



(12) Oodemas crassicorne Blackburn, 



Oode^nas crassicorne Blackb. Tr. Dublin Soc. iii. 1885, p. 184. 

 The sexual distinctions are important in this species, the second joint of the front 

 tarsi of the ^ being much wider than that of the %. 



Hab. Lanai Mountains (2000 — 3000 ft.). Not rare. 



{^i^ Oodemas haleakalae, sp. nov. 



Elongato-ovale, nitidum, aenescens. Rostrum rugoso-punctatum ; oculi parum 

 convexi. Antennarum articulo secundo brevi, tertio elongate. Pronotum baud trans- 

 versum, antice angustatum. Elytra antice levissime vel vix striata, lateribus bisinuatis, 

 striis subtiliter remote punctatis, interstitiis saepe crebre punctulatis, postice (prae- 

 cipue ?) sat convexis. Tarsorum ant. ^ articulus secundus transversus, tertius hoc 

 multo latior, lobis magnis. Long. 3 — 4*5 mm. 



This species is closely allied to O. crassicorne, Blk. It varies greatly in size, small 

 males being only about half the bulk of the female, and in sculpture, the puncturation 

 of the elytra being much more developed in some examples than in others. It may be 

 distinguished from the allied species by the longer rostrum and less convex eyes, and 

 the former is generally more rugosely punctured, especially in the female. The rostrum 

 is generally more or less evidently widened towards the apex, and is often distinctly 

 carinate down the middle. The interstitial puncturation of the elytra is as a rule hardly 

 less developed than that of the striae. Towards the apex (especially in the $) the 

 interstices become rather strongly convex, the fourth, fifth and sixth terminating 

 somewhat abruptly at the same point, a character which will distinguish this species 

 from some others of very similar appearance (e.g. O. iarduni, Blk.). 



Hab. Maui, Haleakala (5000 — 6000 ft.) ; common. 



(14) Oodemas montamim, sp. nov. 



Nigroaeneum, nitidum, ovale. Antennae crassae, scapo brevi, funiculi articulo 

 primo elongato, crasso, secundo subaequali. Rostrum nitidum, subfortiter punctatum, 

 apice leviter dilatato, fortius decurvato. Oculi convexi et prominuli. Pronotum sat 

 longum, subtilissime punctatum, antice fortiter angustatum. Elytra nitida, seriatim nee 

 grosse punctata, vix evidenter striata, interstitiis subtiliter minus dense punctatis. 

 (Sexus ?) Long, vix 4 mm. 



This species very closely resembles O. tardum Blackb., but the very stout
