46o FAUNA HAWAIIENSIS 



A single male from Molokai differs from A. viacrothorax in the characters given 

 above. The punctures on the prothorax are obsolete, with striae radiating from them 

 in a stellate manner, as in Eupctiims marginatus. The supplementary segment tapers, 

 but is rounded at the apex ; pygidium truncate with rounded angles. The wings are 

 about half as long as the elytra. 



Hab. Molokai, over 4000 ft., 15. vi. 1893 (Perkins). H. S.

This species was described from a single very good male specimen from the 

 mountains near Honolulu. We have now a series of 128 specimens, almost all of 

 which are darker than the original specimen, which was scarcely mature ; it was 

 described as " ferrugineo-testaceus " in the original diagnosis. " Fusco-ferrugineus, 

 prothorace interdum minus infuscato" is applicable to our series. The head and eyes 

 are small. The alternate interstices of the elytra form conspicuous ridges, which are, 

 however, frequently interrupted by vague inequalities of the surface. The pubescence 

 on the abdomen is less coarse and dense than in some allied species. 



The abdomen is acuminate. The male supplementary segment is obtusely acumi- 

 nate, with a number of long hairs at the apex. The male pygidium is somewhat long, 

 narrow and convex, having a truncated ape.x with rounded angles ; female pygidium 

 shorter and broader, rounded at the apex. 



We have examined the wings of several specimens, and find them less than half 

 as long as the elytra, somewhat triangular in shape ; rather like those of Cyrtostolus 

 suhalatiis, but more reduced. 



Hab. Oahu ; Honolulu mountains, end of Koolau range, &c. ; found in numbers 

 only in one spot, on the ground, in dead leaves ; xi. and .\;ii. 1900, vi. 1901 (Perkins).

(4) Apetimis brevis. Sharp. 



Brachypeplus brevis Sharp, Tr. ent. Soc. London, 1878, p. 137. 

 This is allied to A. explanatus, though very much smaller, and with much feebler 

 legs. It has not been found by Mr Perkins. 



Hab. Oahu, "by sifting dead leaves at the foot of a precipitous cliff" (Blackburn). 



(5) Apetimis piimilio, sp. nov. 

 Brevis, latiusculus, convexus, sordide testaceus, sat nitidus, parce pubescens, oculis 

 parvis ; prothorace lateribus rotundatis, crebre jDunctato, disco obsolete quadri-impresso; 

 elytris brevibus et latis, seriatim punctatis, interstitio quinto pone basin magis elevato ; 

 abdomine fortiter, parce punctate. Long, vix 3, lat. vix i^- mm.
