(4) Parandrita gracilis, sp. nov. 



Angustior, depressa, nigra, supra laete aenea, nitida, antennis femoribusque piceis. 

 tibiis tarsisque rufis ; antennis apicem versus gracilibus ; crebrius subtiliter punctata ; 

 elytris striatis. Long. 2^ mm. 



This is of narrower form than the other species so that the head is not transverse ; 

 the punctuation is unusually fine ; the striation of the elytra very definite. Unique. 



Hab. Oahu, Konahuanui Ridge, xii. 1900 (no. 783, Perkins). 



(5) Parandrita molokaiae, sp. nov. 



Depressa, nigra, supra aenescens, elytris aeneo-rufis, antennis piceis, pedibus rufis ; 

 capite thoraceque crebre subtiliter punctatis, hoc intra latus linea impressa : elytris 

 striatis, interstitiis parce punctatis. Long. 3 mm. 



In this species the elytra are of a dark mahogany colour, with only a faint aeneous 

 tinge and no trace of pallid marks. The elytra are deeply striated. There is much 

 hair on the male antennae, and the terminal three joints are rather longer than they 

 are in P. aenea. Three specimens. 



Whether this and the allies may prove really distinct from P. aenea it is difficult 

 to say on so small a material. They appear to be very rare.

(6) Parandrita liturata, sp. nov. 



Depressa, nigra, capite thoraceque subauratis, elytris fusco-nigris, testaceo-signatis, 

 antennis pedibus piceis, vel nigro-piceis. Long. 2^ — 3 mm. 



This is readily distinguished by the variegate elytra, though in other respects but 

 little different from the other Hawaiian species of the genus. The head and thorax 

 are finely, very densely punctured, the thoracic line is very fine. The elytra are in 

 colour about half black and half yellow, the marks consisting of about five yellow 

 connected patches, the most distinct of which is one common to both elytra, placed 

 about half way of the length, and surrounded by black marks separating it almost, 

 but not quite, from the other yellow marks ; they are very distinctly striated, and bear 

 numerous extremely minute setae. Five specimens.
