2o6 FAUNA HAWAII ENSIS 



typical individuals of that species it is readily distinguished by the much less con- 

 spicuous setae on the elytra, and the hardly visible curved setae at the sides of the 

 prothorax. From the less typical examples which I have referred to P. angtdaris, it may 

 be known by the shorter and less slender antennal joints, and its evidently flattened, or 

 subdepressed form. 



The shoulders of the elytra are formed as in P. angtdaris, and are likewise marked 

 with pale squamosity, but as a rule less conspicuously, and the basal ventral segment of 

 the abdomen is strongly punctate. 



Hab. Oahu, Halemano (Koolau range) (2000 ft.), in January, 1893.

The examples from which this species was described, appear to me to be not only 

 immature, but also particularly small and ill-developed specimens. Large individuals 

 are twice the size of the specimens sent by Mr Blackburn, and altogether wider and 

 more bulky, the colour pitchy or reddish pitchy, the elytra red, with dark markings 

 laterally, about the middle, and extending sometimes to the suture. The squamosity 

 is not continuous, there being an oblique spot near the shoulders of the elytra and 

 others behind these. The setae are shorter, and less conspicuous, than those of fresh 

 examples of P. obscuricolor, vestitus and others. The prothorax is much wider, and has 

 the sides much more strongly rounded than in the type, and is often distinctly 3-im- 

 pressed. The eyes, the tarsal lobes, and humeral angles of the elytra are often all 

 much more developed, but all of them vary, even in the larger examples. Length 

 2 — nearly 3 mm. 



Hab. Oahu. Both mountain ranges, at elevations of 2000 — 3000 ft. 



(44) Proterhimis oxygonias, sp. nov. 



P. scutato forma facieque simillimus, colore plerumque minus obscuro, elytrorum 

 angulis humeralibus fortius et acutius productis, distinguendus. ^%. Long. 2*25 — 

 275 mm. 



This species appears to be very closely allied to P. scutatus, from which it differs 

 generally by its less obscure {i.e. more red) colour, the less evenly rounded sides of the 

 thorax, and the more strongly and acutely produced humeral angles of the elytra. 



Hab. Oahu, mountains near Honolulu (2000 ft.). A single example taken in the 

 Waianae range of the same island appears to be a variety of this species.
