COLEOPTERA ^j-j 



(19) Eopenthes itnholor, sp. nov. 



Nigerrimus, nigro-pubescens, sat nitidus, thorace sat fortiter punctate ; tarsis 

 gracilibus, articulo quarto baud abbreviate ; elytris sat profunde striatis. Long. 7 — 8 mm. 



Resembles the variety of E. cognatns with dark legs very closely ; but in addition 

 to having the legs and base of the antennae completely black, it has shorter antennae 

 and a differently shaped thorax, this being less elongate and parallel-sided, with the 

 hind angles more distinctly directed outwards. In E. nnicolor the apices of the elytra 

 are not spinose. This character and the quite simple tarsi completely separate the 

 .species from E. ftinebris, which is similar in colour and size and is also a Kauian 

 species. We have only two males of E. nnicolor.

(20) Eopenthes fnnebris, sp. nov. 



Nigerrimus, gracilis, parum convexus, nitidus, nigro-pubescens, prothorace gracili, 

 fortiter minus dense punctato, antennis pedibusque elongatis, tarsis anterioribus articulis 

 bene dilatatis, articulo quarto brevi ; elytris profunde striatis. Long. 8 mm. 



Though very similar to E. cognatns, this is readily distinguished by the more 

 coarsely punctured thorax, and the considerably shorter fourth joint of the tarsi ; this 

 last character is correlative with an evident incrassation of the basal joints. There is 

 no doubt of the distinctness of this insect, though we have only two male specimens. 



Hab. Kauai, mts. Waimea, 3000 ft. vi. 1894 ; high plateau, viii. 1S96 (Perkins). 



(21) Eopenthes p/ebeius, sp. nov. 



Rufus, plus minusve infuscatus, vix nitidus, pube elongata pallida vestitus ; 

 prothorace crebre fortiter punctato, angulis posterioribus evidenter divergentibus ; 

 elytrorum marginibus saepe dilutioribus. Long. 9 — gf mm. 



We have six e.xamples of this species, all of which are males. It appears to be 

 variable as to colour, but not in a definite (or racial) manner. One of its most 

 conspicuous characters is the pallid pubescence, which is longer and more conspicuous 

 than usual. The head is never quite black. The punctuation of the thorax is rather 

 dense and coarse ; the elytra are deeply striate, and the punctuation of the interstices 

 makes them rough ; the apices have no spine, or only a minute trace of one, at the tips. 

 The legs and antennae are elongfate. 



The parts of the body are more or less infuscate. In the example with greatest 

 development of this dark colour, the thorax is nearly entirely black : the insect then 

 resembles the male of E. obscnrns, but the side margins of the elytra as well as
