Coleoiitera from the Hawaiian Islands. 93 



part of the surface, of a mark on the elytra between the 

 suture and shoulder, of another mark behind the iniddle, 

 and of an infuscation of the posterior part of the suture ; 

 these marks are no doubt very variable in the extent to 

 which they are developed. The very dense, very fine, 

 and very short sette Avith which the upper sui-face is 

 covered may easily be overlooked. 



Found on Waianae mountains, Oahu, and sent to me 

 as No. 36. Specimens, which are apparently varieties of 

 the same species, have been found on Halea Kala, INIaui 

 Island, and on the mountains of Kauai.

 punctatis, apice impunctatis ; pedibus antennisque tes-

The thorax is rather elongate and narrow, distinctly 

 narrower than the elytra ; and the lateral and basal 

 margins are excessively fine and difficult to distinguish. 

 The elytra are slightly narrowed towards the shoulders ; 

 the black mark at their outer margin does not extend to 

 the apex. The species is readily distinguished by its 

 shining surface fi*ee from set^e, and the pale, almost white 

 elytra, with black marks, as well as by the punctuation of 

 the elytra. The colour is probably variable, as two 

 individuals apparently belonging to the species have the 

 thorax entirely yellow. 



Found on the mountains near Honolulu, sent by 

 Mr. Blackburn as No. 34. 



Cis tnbidus, n. sp. Oblongus, angustulus, sat convexus, 

 nitidus fere Ifevigatus, nigro-fuscus, elytris sordide testaceis, 

 lateribus fasciaque mediali parum discrete nigris ; thorace 

 elytrisque parum fortiter et dense punctatis, his ad apicem 

 fere impunctatis, antennis pedibusque testaceis, illis clava 

 fusca. Long. 1| mm. ; lat. § mm. 



The front margin of the thoi-ax is more or less distinctly 

 pale ; the thorax is nearly as broad as the elytra, and is 

 but little longer in the middle than it is at the sides. The
