530 Mr. DPhaxp on some new 
Proterhinus angularis, n. 8. 
Angustulus, nigricans, rostro, antennis pedibusque plus 
minusve rufescentibus, parum squamoso-variegatus ; 
elytris macula pallida squamosa ad humeros, setulis 
elongatis erectis crebre adspersis, fortiter punctatis, 
humeris liberis, antrorsum sat prominulis. Long. 
23—3 mm. 
@. Antenne not very long; the 9th joint not greatly 
different from the 8th. Eyes moderately large. Thorax 
elongate; the anterior part not abruptly constricted ; 
behind the front with a deep distinct impression ; the 
surface coarsely punctate, with only a very scanty 
clothing of sete. Elytra rather elongate and narrow, 
a good deal emarginate at the base, so that the humeral 
angles are distinctly prominent, but not elongate; they 
are dull, coarsely punctate, and have a very conspicuous 
patch of pale scales at the humeral angles, besides 
some more or less distinct squamous patches near the 
extremity, and with rather numerous, elongate, erect 
sete. Legs apparently varying from red to black, with 
the tarsi red. 
I have seen only the female. The species appears 
allied to two very distinct ones, viz., P. nigricans and 
P. longulus; it differs from the former by the more 
slender elongate form, and more angulate shoulders to 
the elytra, and by the elongate sete. In form it 
approaches to P. longulus, but the eyes are larger, the 
thoracic impression conspicuous, and the sete of the 
elytra elongate. The conspicuous humeral patch of 
squamosity will, I think, assist much in the identification 
of the species. 
Beaten from trees on a mountain near Honolulu.
