COLEOPTERA 633 



clava % multo minor, articulo primo angusto, circa bis longiore quam latiore. Elytra 

 minus fortiter elongata, ex majore parte fere glabra, parcissime vel etiam vix evidenter 

 punctata, conspicue subtiliter loiigitudinaliter rugulosa, parte apicali dense minute 

 punctata et pallide saepe flavide pubescente. Long. 275 — 3 mm. 



I have seen only 5 examples of this species and there is some variation in the 

 development of the individuals, but I cannot douijt that they are one species. The 

 colour of the antennae &c. varies as in many other species. One example was taken 

 close to Honolulu in the mountains at 1500 ft. in 1896, two more in 1900, and two in 

 the same range but twenty miles away in 1901. It would therefore seem to be rather 

 scarce. 



Hab. Oahu, near Honolulu and elsewhere, 1500 ft. 



(46) Mu'ostcrnus suhparcns, sp. nov. 



Capite et pronoto brunneis aut rufescentibus, elytris brunneo-nigris, marginibus et 

 circa suturam apicem versus pallidioribus, RI. pajro cognatissimus, sed oculis conspicue 

 majoribus distinguendus. 



I separate a single specimen from M. parens on account of the conspicuously 

 larger eyes, the width of one of these, in a front view of the face, being about equal to 

 the space between the eyes. I see no other specific character. 



This specimen was collected by Koebele on Oahu, on one of the occasions when 

 he accompanied me, but it bears no definite locality label. 



Hab. Oahu; collected by A. Koebele in 1900 or 1901. 



(47) AJii-ostcnuis hypocochis, sp. nov. 



Major, rufescens, flavo-pubescens, elytris nigrocastaneis, apicaliter rufescentibus. 

 Oculi magni, sed late clistantes. Antennarum clava major, articuli primi et secundi 

 angulo interno haud acuto, apicibus minus fortiter productis. Elytra ex magna parte 

 fere glabra, perparce punctata, nitida, parte apicali densissime subtilissime punctata, 

 ibique conspicue flavo-pubescente, parte suturali utrinque angustissime crebre punctata, 

 basi extrema evidenter flavo-pubescente et subtilissime crebre punctata, sutura in parte 

 elytrorum declivi fortiter impressa. Metasternum postice profunde concavum, antice 

 distincte carinatum. Long. 375 mm. 



Only one example of this species was taken. It was in company with M. enceras, 

 which in some respects it greatly resembles. It is allied apparently to M. cognaiics, but 

 easily distinguished from that and AI. konantis by the close puncturation at the base of 

 the elytra. I feel quite uncertain of the se.x of the unique specimen. 



Hab. Molokai, on the lowest edge of the forest above Kaunakakai.
