192 FAUNA HAWAIIENSIS 



are widely red at the base, and covered with pale squamosity, generally over a sub- 

 triangular area ; behind this are two large black, or dark, lateral spots, extending nearly 

 to the suture, and free from squamous covering ; the apical portion is often more or less 

 infuscate, and the squamosity broken up into spots. 



Hab. Kauai mountains (4000 ft.) ; found very sparingly on several occasions.

Proterhinus scutatus Blackburn, Tr. Dublin Soc. iii. 1885, p. 169. 



I have taken only three or four examples of this species, which mostly quite agree 

 with those collected by Mr Blackburn. This insect is much less clothed with squamosity 

 than most of the species, the thorax being nearly bare, and the elytra in fresh examples 

 very little squamose, except for two longitudinal lines extending backwards from their 

 shoulders ; but the latter bear numerous short and rather thick erect setae, which are 

 pale in colour and quite conspicuous. In structure this species closely resembles some 

 examples of P. simplex, but it is no doubt distinct. 



Hab. Kauai, 2500 ft. (Blackburn) ; (2000 — 4000 ft.), in the Waimea district. 



(15) Proterhimis sctiilostts, sp. nov. 



Ferrugineus, elongatus, angustulus, setulis erectis brevibus vestitus, elytris non- 

 nunquam nigro-maculatis. Antennae plerumque breviores, concolores, rufae. Rostrum 

 $ breve, fortiter longitudinaliter rugosum, paullo vel baud longius quam latius. Prono- 

 tum minus latum, plerumque plus minusve evidenter 3-impressum, setis appressis parce, 

 aliisque erectis, vestitum. Elytra fortiter elongata, lateribus subparallelis, subseriatim 

 punctata, setis brevibus erectis vestita, vix aequaliter convexa, angulis humeralibus 

 distinctis, paullo productis, vel fere rectis. Femora postica parum fortiter clavata, 

 tarsorum anticorum lobis parvis. $ $. Long. 2*5 — 3 mm. 



In its rufescent colour, elongate elytra, and the absence of squamosity, this species 

 somewhat resembles the P. loiigulus Sh. of Oahu, and the other species allied thereto. 

 It is however more nearly allied to P. blackburni Sh. &c., the second joint of the 

 antennae in certain aspects being not much shorter (though more robust) than the 

 third, and the short rostrum of the ? is coarsely sculptured. The seven or eight 

 examples taken exhibit some variation, the antennae being decidedly less short in some 

 than in others. The dorsal surface of the elytra is somewhat flattened, and, at least in 

 some examples, there are traces of longitudinal raised lines. 



Hab. Kauai (2500 — 4000 ft.); not common.
