COLEOPTERA 559 



(11) Oligota {Ncsoligota) cribripennis, sp nov. 



Lata, brevis, fere glabra, nigricans, antennis pedibusque testaceis, elytris piceis 

 profunde remote punctatis. Long. \ mm. 



A very broad, compact little insect ; closely allied to O. glabra, but comparatively 

 broader, and distinguished by the more definite punctures on the elytra. The surface 

 is almost destitute of pubescence. Four specimens. 



Hab. Kauai, Halemanu, 4000 ft. v. 1895 (Perkins). 



(12) Oligota (^Nesoligota) ciirrax, sp. nov. 



Lata, subglabra, nigra, antennis palpis pedibusque testaceis, femoribus fuscis ; pube 

 rara sed minus minuta vestita; elytris parcius fortiter punctatis. Long. i|- mm. 



This is very closely allied to O. glabra; slightly larger, with the sculpture and 

 pubescence more distinct, and the legs a little longer. Though we have only one 

 example I have little doubt as to its being distinct. 



Hab. Hawaii, Olaa, xi. and xii. 1S96 (Perkins), 



(13) Oligota {Ncsoligota) glabra. Sharp. 



Oligota glabra Sharp, Tr. ent. Soc. London, 1880, p. 46. 



This is the most robust of the Hawaiian allied forms. In the mature state the 

 colour is black, the antennae and legs yellow, but the latter always more or less in- 

 fuscate, sometimes strongly infuscate; the club of the antenna may sometimes be slightly 

 obscured in colour, especially at the tip. The sculpture is peculiar, consisting of a few 

 large distant, shallow punctures, on the anterior parts only ; the abdomen is destitute of 

 punctuation, but its surface is finely coriaceous. The pubescence is excessively slight, so 

 that it does not affect the shiningness of the surface, which however is much diminished 

 by the minute coriaceous sculpture. 



The specimens above described occur on several islands, but they exhibit consider- 

 able variation, so that it is probable that there may prove to be more than one species. 

 The most remarkable point in the variation is in the suture between meso- and meta- 

 sternum, which is sometimes obliterated and sometimes strongly developed. In the 

 type specimen it is absent. Cf no. 8 — O. polita — as to this point.
