520 FAUNA HAWAIIENSIS 



the shoulder of each elytron where the punctuation becomes obsolete (PI. XV. fig. 7). 

 (In many species the sculpture in the humeral area differs from that of the rest of the 

 elytra, being often obsolete : in this species the difference is exaggerated, so that a 

 marked smoother area is apparent towards the shoulder.) Beneath, the punctures are 

 large, but much less close than in A. pnnciatjts. The head has a transverse suture 

 before the antennae. Wings not reduced. 



Hab. Oahu ; Waianae mts. iv. 1S92, from Kukui wood (no. 7, Perkins). 



(9) Acritus pitnctatiis, sp. nov. 



Ovalis, haud fortiter nitidus, piceo-niger, antennis pedibusque fusco-testaceis ; 

 prothorace crebre punctato ; elytris fortiter ac dense punctatis, ad apices parum rugosis ; 

 pygidio subtiliter punctato ; prosterno oblongo, striis subparallelis, antice parum diver- 

 gentibus ; mesosterno haud impresso ; hoc et metasterno et segmento abdominis primo 

 fortiter ac sat dense punctatis. Long. corp. i^ mm. 



Plate XV. figs. 8, 9. 



This species has a peculiar slightly dull appearance, partly due to closeness of the 

 punctures, partly to the surface between them being microscopically rugulose or aluta- 

 ceous. Head with some very fine punctures, the transverse suture just in front of the 

 antennae distinct. Prothorax with numerous punctures ; a series of punctures along 

 the extreme base, but no special sculpture or impression before the base. Elytra with 

 large close punctures, extending right to the apices, where they are somewhat drawn 

 out into rugosities. Oblique striae near the shoulder sometimes slightly marked. 

 Pygidium and propygidium with very fine, rather obsolete punctures. Prosternum 

 with the keel slightly convex, finely punctured, oblong, about if times as long as its 

 breadth in the median portion, the striae nearly parallel, only slightly divergent in 

 front. Mesosternum, metasternum and first abdominal segment strongly punctured, 

 the punctures becoming very small and obsolete over only a small area in the middle 

 of the metasternum : meso-metasternal suture very faintly marked. Wings not reduced. 

 Seventeen specimens.
