528 Mr. DFharp on some new 
Antenne rather slender; 2nd joint elongate, fully as 
long as and rather thicker than the 8rd; 9th joint a 
good deal stouter and longer than the 8th. Thorax 
appearing nearly straight at the sides, but constricted 
before and behind, very coarsely punctate, the punctures 
causing the sides to appear serrate ; the sides and front 
armed with elongate sete, the surface with some shorter 
scanty curved depressed sete. Elytra coarsely punctate, 
and bearing numerous elongate sete, and besides these 
with some depressed short setze which replace, to a certain 
extent, the squamosity of other species. 
I have a pair of this species before me; the female 
differs from the male, not only by the rostrate head, but 
also by having the surface dull and the sculpture more 
indefinite. It is allied to P. blackburni, but is very much 
larger and more elongate. 
Mr. Blackburn informs me this species is ‘‘ not very 
rare” on the mountains of Hawaii. 
Proterhinus dispar, uu. 8. 
Rufo-niger, parcius squamosus, elytris setulis albidis, 
brevibus, erectis parce minutis; prothorace impresso, 
impressione anteriore magno; elytris parce fortiter 
punctatis, humeris fere rectangularibus, basi rufo. Long. 
mas 4, fem. 3 mm. 
Antenne largely developed, nearly black; the 9th 
joint a good deal broader and longer than its predecessor. 
Kyes very prominent. Thorax a good deal rounded at 
the sides, and with a distinct, abruptly constricted 
anterior portion ; just behind the middle, on each side, 
there is a rather large impression, and a very large one 
in front, in the middle ; the surface is coarsely punctate, 
and apparently but little squamose. The elytra also are 
but little squamose, and their erect sete are not numerous, 
and are rather short; the shoulders are just a little 
prominent, and so are only slightly acute ; the colour is 
black or pitchy red, with a large patch of dark red at 
the shoulder of each; they are quite dull, and .bear 
coarse deep punctures. The front cox are very widely 
separated. 
The male is twice the size of the female, and has the 
front of the head produced into a short, broad, punctate, 
not shining, rostrum, and its antenne are more elongate,
