which has the prothorax differently shaped, and differs in so many details that it 

 scarcely suggests an alliance with this species. The female pygidium is rather narrow 

 apically. Five specimens.

This little insect is somewhat variable as regards the colour of the thora.x and 

 abdomen, but the elytra are always greyish-yellow with numerous indefinite dark marks. 

 The sides of the thorax are less rounded than usual, the base is straight, the hind 

 ancles not definite, slightly obtuse and rounded ; the punctuation is dense ; on the front 

 of the thorax in the larger males, very dense. The elytra are dull, with a peculiar 

 silky lustre, the serial punctuation is fine and regular, but the striae are not depressed, 

 so that in some lights the sculpture does not show at all ; the spots of dark colour are 

 vague. The abdomen is less wedge-shaped than usual. The legs very short and thick. 

 The pygidium of the male (PL XIV. fig. 8 a) is broad at the tip, not visibly emarginate, 

 the angles extremely obtuse. The form of the last ventral plate is shown in PI. XIV. 

 fio-. 8 b. Supplementary segment broad, rounded. Female pygidium short, rather 

 narrow and rounded apically. Twenty-four specimens.

(8) Nesopeplus niolokaiensis, sp. nov. 



Sat latus, haud depressus, capite thoraceque rufis, abdomine pectoreque nigri- 

 cantibus, elytris testaceis vage fusco-pictis, antennis pedibusque flavis ; elytris seriatim 

 haud fortiter punctatis. Long. 3^, lat. i^ mm. 



A small series of seven specimens from Molokai can be distinguished from the 

 Oahuan N. vagepictus. The form is a little less parallel, the thorax rather shorter, a 

 little more narrowed in front, and with more rounded hind angles : the elytra! sculpture 

 is slightly coarser, and in the female the punctures of the thorax are not quite so dense. 

 The male pygidium is not emarginate, and has very blunt angles. If looked on as a 

 variation of N. vagepictus it is of interest as being dissimilar from N. roridus which may 

 almost with equal reason be considered a variety.
