664 FAUNA HAWAIIENSIS 



Proterhinus oscillans Sharp. 



P. oscillans Sharp, huj. op. ii., p. 210. 



This species is not very variable and is rather easily recognized, though very closely 

 allied to P. deceptor, P. subdeceptor and others. It is generally distributed over Oahu 

 in both ranges and is attached to Acacia koa. 



Proterliiniis pachycncniis Perk. 



P. pachycnemis Perk., huj. op. 11., p. 211. 



The female of this species, which was not contained in my earlier collections, 

 resembles the male in general appearance, but lacks the enormous development of the 

 femora. It may, however, be easily recognized by the long second joint of the antennae, 

 which is as long as or longer than, the third and is much stouter than the latter. 



Protcrliimts deceptor Perk. 



P. deceptor Perk., huj. op. 11., p. 245. 



This species is common in the Koolau range of Oahu, near Honolulu and elsewhere 

 and, no doubt, in my earlier collections I referred examples of other species to it. It 

 affects the lower altitudes in the mountains and is abundant on the Hau tree {Hibiscus 

 tiliaceus). I have now examined many examples and the variation does not seem to be 

 excessive. 



Hab. Oahu; common and generally distributed. 



(12) Proterhinus sjtbdeceptor, sp. nov. 



This species is almost similar to P. deceptor, but having examined a very fine 

 series, I find that it is evidently more elongate ; the elytral clothing has not the same 

 tendency to form spots and the erect setae are less developed, less numerous, and almost 

 confined to the posterior parts of the elytra. 



The colour of the elytra is usually red or reddish, with black or fuscous marking 

 each side, often forming a median band. In small dark specimens nearly the whole of 

 the elytra is occupied by this black colour except the basal third. The pronotum is 

 very densely clothed at the sides with appressed pale squamosity, and very rarely it is 

 almost equally dense between these areas. Usually a number of the basal joints of the 

 antennae are clear red, but sometimes only the scape is of this colour, while in others 

 the antennae are entirely black. 



Hab. Oahu ; widely distributed in the Koolau range. I have taken it commonly 

 from stems of Alyxia.
