COLEOPTERA 207 



{45) Proterhimis leptothrix, sp. nov. 



Haud latus, rufescens, elytris plus minus nigro- vel fusco-signatis. Oculi minores. 

 Antennae mediocres, clava 2-articulata, articulo 9° vix quam 8"' evidenter latiore. Pro- 

 notum parum squamosum, dense rugoso-punctatum, setisque erectis gracillimis versus 

 latera sat conspicue vestitum, antice impressum, angulis posticis macula pallida squamosa 

 signatis. Elytra plus minusve albido-squamosa, setis erectis gracillimis et elongatis 

 conspicue vestita, humeris acutis, plus minusve productis. Pedes setis conspicue 

 elongatis vestiti, tarsorum anticorum lobis parvis. $. Long. 2 — 2 "5 mm. (Plate IX. 



% 13. ?■) 



A very distinct species, owing to the form of the antennae, and the e.xtremely fine 

 and more than usually elongate setae, which clothe the elytra and legs. The club of the 

 antennae can hardly be considered as consisting of more than two joints, as the 9th 

 in whatever aspect it is viewed is hardly different in form to those that precede it. 

 A single example taken in the same locality as the $ above described is no doubt the $, 

 as it differs only in being smaller and in the usual se.xual characters, but it is a good 

 deal abraded. 



Hab. Oahu ; Kaala (3000 ft.), Waianae range ; 2 ? taken together in December, 

 1892, and a single $ in the same month but on another occasion. 



(46) Proterhinus seticollis, sp. nov. 



Praecedenti cognatissimus, sed colore obscuriore, setisque erectis elytrorum minus 

 longis gracilibusque distinguendus. ^ $. Long. 2 — 2*75 mm. 



This species is very closely allied to P. leptothrix, and may possibly on the 

 examination of a long series prove to be a form of that species. It is very easily 

 distinguished, so far as the few examples taken are concerned, by the different clothing, 

 the erect setae being much less elongate and slender. It is also generally of a darker 

 colour, and superficially greatly resembles P. scutatiis, from which it is abundantly 

 distinct by the 2-jointed club of the antennae, the stronger longitudinal furrows of the 

 rostrum in the ?, the patch of white squamosity at the hind angles of the thorax, which 

 bears conspicuous erect setae, &c. 



Hab. Oahu, Waianae mountains (3000 ft.) ; a few examples taken on the opposite 

 side of the range to the locality for P. leptothrix.
