I30 FAUNA HAWAIIENSIS 



the Z these joints are unusually short, and either of them is only about the length of the 

 basal joint of the club. The sculpture of the prothorax is largely concealed by the 

 pubescence, its surface is roughened by minute tubercles, and the puncturation is 

 indistinct. The elytra are seriately punctured, and entirely covered with pubescence, 

 which shows no tendency to form lines, and are united to the extreme apex. There are 

 very distinct tubercles sparsely scattered over the surface, many of which terminate in a 

 single short bristle. The apical ventral segment of the hind-body in the ^ is of a 

 reddish colour, densely pubescent, and truncate at the apex. The rest of the ventral 

 surface is conspicuously, but less densely, pubescent. 



Hab. Kauai, Halemanu (4000 ft.) ; x ^ i $ taken. 



(18) Rhyncogonns sylvicola, sp. nov. 



Minor, niger, vix nitidus, pubescens, prothorace subelongato, rugoso-punctato. 

 Elytra ad basim prothorace latiora, tuberculis rare dispositis munita, apicibus breviter 

 liberis. $. Long. 9 — 9-5 mm. 



Allied to the preceding, but blacker in colour, and the surface less dull. The 

 prothorax is evidently longer, and its puncturation, which is dense and rugose, is 

 distinct. The elytra have scattered tubercles much as in that species, but they are 

 evidently wider at the base, so that the humeral angles stand out somewhat from 

 the hind angles of the prothorax, and their extreme apices are free.
