COLEOFTERA 143 



(10) Dryophthoi'us pnsillus Sharp. 



Dryophihorns pusillus Sharp, t. c. p. 24. 



Hab. Oahu (Blackburn) ; in stems of the tree-fern. I have never met with this 

 species. 



(11) Diyopht horns oahuensis, sp. nov. 



Species minima, minus lata, rufescens, capite nigricante. Rostrum (^) latum, 

 rugosum, et opacum. Pronotum antice fortiter constrictum, grosse rugoso-punctatum. 

 Elytra seriatim grosse punctata, interstitiis omnibus distinctis, 2° et 4° quam 3° et 5° 

 paullo fortius elevatis, 6° ad apicem declivem fortissime carinato-elevato. Long. Z 

 (rostr. incl.) 27 mm. 



The rostrum is rather short and broad, the pterygia strongly outstanding. The 

 eyes are feebly facetted. The puncturation of the prothorax is coarse and rugose but 

 apparently shallow. All the interstices of the elytra are distinct, but not wide, the 

 second and fourth a little more raised than the third and fifth, and not interrupted, the 

 sixth alone forms the extremely strongly elevated apical side-margin. The species is 

 very distinct. 



Hab. Oahu. A single example (.?) taken in the Waianae mountains (3000 ft). 



(12) Dryophthorus kauaiensis, sp. nov. 



Species minima, rufescens. Caput (^) cum rostro rugoso-punctatum, squamosum. 

 Pronotum dense grossissime rugoso-punctatum, antice constrictum. Elytra sat grosse 

 seriatim punctata, interstitio 2°, 4° et 6° haud interrupte carinato-elevatis, tertio sub- 

 obsoleto. Long. ^ vix 3 mm. 



This species is allied to D. oaJmensis, but it is a little larger, and abundantly 

 distinct by the sculpture of the elytra, the sharply carinate form of the second and 

 fourth interstices readily separating the two. The apical margin is formed by the sixth 

 interstice, which is strongly raised towards the apex. In D. ptisilbis Shp., which is a 

 small species, the fourth interstice is continuous with that margin, as also is the case 

 with D. niodestus Shp. Both in D. kauaiensis and the preceding species the eighth 

 interstice forms a part of the lateral outline towards the base of the elytra, in dorsal 

 aspect. In the present species indeed it is rather strongly raised. 



Hab. Kauai. A single J taken in the mountains (4000 ft.).
