3/8 FAUNA HAWAIIENSIS 



the base remain pale, and the pubescence of the surface is very different. It is 

 considerably larger than E. satelles of the same island and has not a definitely black 

 head and thorax. 



Hab. Lanai. Lanaihale ; above Koele ; Halepaakai ; July, 1894 (Perkins). 



(22) Eopenthcs aydiiiis, sp. nov. 



Rufescens, nitidus, pube pallida minus conspicue vestitus, capite nigricante, antennis 

 fusco-rufis ; prothorace sat crebre minus fortiter punctate ; elytris profunde striatis, 

 apicibus minus attenuatis, minute spinosis. Long. 7^^ — 8^ mm. 



We have one male and three females of this species ; it is very difficult to 

 distinguish by good characters from either E. antennatiis or E. ambiguiis, but I believe 

 it will prove distinct. It is considerably larger and broader than E. ambignus, and the 

 coloration though variable in both appears never to quite agree : the feet are not black 

 in E. arditns, and the thorax is not red with a large black patch on the middle, but 

 is either nearly red or nearly black. 



It is apparently smaller than the inadequately known E. anfennatus, and is less 

 depressed, and has the thorax less straight-sided, and the sides less convergent in front. 



Hab. Oahu (Perkins). 



(23) Eopenthcs antennatiis, sp. nov. 



Fusco-niger, elytrorum basi vage rufescente, antennis pedibusque fusco-rufis ; 

 thorace elongato, antrorsum angustato, dense fortiter punctato. Long. 10 — 10^ mm. 



Var. Thorace parcius punctato, elytris concoloribus. 



Distinguished from E. konae by the larger development of the antennae of the 

 male, and by the thorax being regularly narrowed to the front. The antennae are 

 5 mm. long, their joints are broader and more serrate than they are in E. konae. Six 

 specimens. There is a great deal of discrepancy in these individuals, so that if they 

 are all one species it must be a very variable one. 



Hab. Oahu, viii. 1900 (Perkins). 



(24) Eopenthcs oahnensis, sp. nov. 



Niger, nitidus, parce subtiliter pubescens, elytris summa basi flavescente, pedibus 

 testaceis, antennis testaceis vel fusco-testaceis basi testacea ; prothorace parce punctato. 

 Long, y—jh mm. 



Narrow, with the hind angles of the thorax but little divergent. Though rather 

 similar to some of the varieties of E. konae there is no doubt of its distinctnes.s. Four 

 specimens. 



Hab. Oahu (Perkins).
