Coleoptera from the Hawatan Islands. 531 
Antenne stout, not elongate ; 2nd joint thick, stouter 
than the 8rd, and but little shorter than it; 9th dis- 
tinctly longer and thicker than 8th. Thorax evenly 
rounded at the sides, and so without constricted anterior 
portion ; behind the front margin, in the middle, with a 
large but indefinite impression ; the surface dull, without 
distinct puncturation, but with a good deal of squamosity, 
which is not arranged so as to form any pattern. Hlytra 
rather elongate and narrow; the shoulders but little dis- 
engaged from the thorax, and not prominent ; the surface 
red, with a dark patch on each side, with deep, extremely 
large, punctures, with a fine irregular squamosity, and 
forming definite marks, and with short erect pale sete. 
Legs thick, pale red. 
In the male the front of the head is rather elongate, 
and the antenne are rather stouter than in the female, 
the 1st and 2nd joints especially being thicker. 
The species is remarkable for the coarse puncturation 
of the elytra. It is allied to P. oscillans, but is much 
larger and more elongate, and has the antenne thicker, 
and I should think it is most probably distinct. 
This was taken on the island of Maui, I believe. 
Proterhinus validus, n.s. 
Major, suboblongus, piceus, supra cum _ pedibus 
ochraceo-tomentosus, setulis erectis munitus; oculis 
perprominulis ; prothorace conspicue trifoveolato, elytris 
inequalibus, fortiter punctatis, humeris antrorsum promi- 
nulis. Long. 4$—53 mm. 
Antenne short, much clothed with hairs and sete ; 
2nd joint greatly shorter than 3rd ; 8th distinctly shorter 
than 7th; the three terminal joints each thicker but 
not much longer than the 8th. Head closely and 
roughly tomentose. Thorax large, much narrowed in 
front; the narrow front part elongate, but not abruptly 
separated from the posterior portion; on each side, just 
behind the middle, with a very large and distinct fovea, 
and the middle, behind the front margin, very broadly 
but less definitely impressed; the surface clothed with 
curved sete, some of which, more especially those about 
the front and sides, are elongate and suberect, while 
others become so short and depressed as not to differ 
from tomentum. Elytra large; the shoulders prominent 
in front; at the base on each side, some distance from
