COLEOPTERA 227 



One of the smallest species of the genus generally remarkable for being entirely, 

 or for the most part, of a rufescent colour. The series of over a score of individuals 

 exhibit not a little variation, and the tendency in some of them to become very narrow 

 and elongate in form is remarkable, although a similar tendency is observed in several 

 other species. Certain individuals approach very closely to some varieties of P. deceptor, 

 but I cannot consider the two species identical. 



Hab. Maui, lao valley. A series of examples taken in March 1894. All were 

 obtained at the same time and place. A single example taken on Molokai perhaps 

 belongs to this species. 



D. Species insulae Lanai propriae.

 and 45. 



This species is distinct at a glance by its large size (although it is of rather narrow 

 form), and the very strongly elongate slender antennae of the ^, with their exceeding 

 long but stout basal joint. In the % this joint also is extremely elongated, but less so 

 than that of the ^. Length 3 '5 — 4*5 mm. 



Hab. Lanai, mountains (2000 — 3000 ft.) ; rare, only about a dozen examples 

 were taken. 



(86) Proterhimis loiigicornis Sharp. 



Proierhimis longicornis Sharp, Tr. Dublin Soc. iii. 1885, p. 173. 



Z readily distinguished by the unusually long antennae, and especially of the 8th 

 joint, which is longer than the following or basal joint of the club. The antennae of 

 the % are much shorter, but the unusual length of the 8th joint is noticeable also in this 

 sex. The species appears to be most closely allied to P. kamptarthrus of Oahu, but 

 the two are very distinct. Length 2-5 — 375 mm. 



Hab. Lanai, mountains ; rare, less than a score of specimens taken. 



(87) Proterhinus lanaiensis, sp, nov. 



Statura majore, suboblongus, rufo-niger, elytris plus minusve variegatis. Antennae 



gracillimae, rufae, apicibus nonnunquam nigris, clava distincte 3-articulata. Oculi 



magni, coniformes, fortiter prominentes. Caput post oculos fortiter constrictum. Pro- 



notum dense aureo-squamosum, distincte 3-impressum, setis curvatis conspicuis. Elytra
