458. FAUNA HAWAIIENSIS 



Apetasimus, gen. nov. 



Pedes breves, tarsorum lobi parvi. Metasternum breve. Alae minutae. 



Plate XIII. fig. 26, wing. 



In this genus the wings are much more aborted than in Cyrtostohis, being quite 

 minute. The front angles of the thorax project forwards on either side of the head 

 much less in this genus than in the allied Cyrtostolus. The metasternum is short ; and 

 the coxal process of the abdomen is broader, and has its margin less arched, than in 

 Cyrtostolus. The distance between the posterior coxae, which is characteristic of this 

 division of Hawaiian Nitidulidae, almost reaches a maximum in this form. On the 

 other hand, the tarsal lobes are small, a character which is very striking when Apetasimus 

 is compared with such of its allies as Goniothorax. The apex of the prosternal process 

 is much bent upwards; the prothorax is more conve.x transversely than it is in Oj'thostolus, 

 but there is very little e.xplanation of its sides. The genus is a very peculiar one. D. S. 



(i) Apetasimus involucer, sp. nov. 



Convexus, nitidus, fusco-ferrugineus, antennis pedibusque ferrugineis, crebre 

 punctatus, parce pubescens ; prothorace transverso, convexo, ad latera nullo mode 

 explanato, anterius angustiore, disco obsolete quadri-impresso ; elytris marginibus pos- 

 terioribus fere rectis, ad latera parum explanatis, sulcis punctis magnis, interstitiis 

 punctis parvis. Maris pygidium conspicue emarginatum. Long. corp. 4 — 5 mm. ; 

 lat. Corp. 2 mm. 



Plate XIII. fig. 25, ?. 



This species is very distinct in general appearance from those of the genera 

 Orthostolus and Cyrtostolus, and is further separated from them by its minute wings 

 (PI. XIII. fig. 26). 



In one specimen the four depressions on the prothorax are fairly distinct ; in the 

 others, hardly present. The notch in the ^ pygidium is broad and rather deep, the 

 pygidium forming a narrow and somewhat sharp piece on either side of it. t supple- 

 mentary segment terminally almost truncate. The % pygidium is somewhat long, and 

 narrow at the ape.x, rather truncate with rounded angles, and an extremely slight de- 

 pression on the posterior margin. 10 specimens.

Apetinus, gen. nov. 



Sulci antennarii convergentes. Prosterni processus ad apicem nullo modo re- 

 curvatus, brevissime ciliatus. Coxae posteriores distantes. Metasternum brevius eo 

 Eupetini. Alae abbreviatae.
