2 70 FAUNA HAWAIIENSIS 



margin being sometimes connected with the wide transverse fascia, but sometimes are 

 altogether wanting. The extreme apex of the elytra is usually dark. The meso- 

 sternum is prolonged subhorizontally in front of the coxae, almost continuing the plane 

 of the metasternum. It is coarsely sculptured except for the very narrow front margin 

 which is overlapped by the prosternum. 



Hab. Molokai. Highest forests above 4000 ft. 



(12) Apterocis subaeneus, sp. nov. 



Praecedenti cognatissimus, sed forma paullo angustiore, prothorace nigro, subaeneo- 

 micante, ad angulos anteriores haud flavo-maculato, distinguendus. Long, vix 2 mm. 



Extremely like A. strigosus but a narrower insect with black slightly aeneous 

 prothorax, which is not maculate at the front angles. The pale setae are observable on 

 the thorax, and on the elytra they are decidedly less inconspicuous than is the case in 

 the preceding species. A series of examples may, however, prove this to be only a 

 variety of A. strigosus. 



Hab. Maui. A single example taken on Haleakala at an elevation of 5000 ft. 



(13) Apterocis Iiystrix, sp. nov. 



Unicolor, testaceus, aut capite nigricante, ovalis, sat convexus, setis erectis elon- 

 gatis dense ubique vestitus. Pronotum latum, postice haud marginatum, densissime 

 subtiliter punctatum. Elytra dense irregulariter rugoso-punctata. Long, circa 2 mm. 



Unlike any other species, in form something like A. strigosus and its allies, the 

 convexity of the elytra and prothorax not forming a very strong and even curve, when 

 viewed laterally. The elytral puncturation is dense, rugulose and indefinite, the punc- 

 tures apparently not being of even size, and but shallowly impressed. 



Hab. Lanai. Two examples (one mutilated) were taken on the top of the 

 mountains.
