124 FAUNA HAWAIIENSIS 



closely punctured. Elytra with regular rows of very closely-set punctures, the interstices 

 narrow, and very smooth and shining ; along the striae there are rows of minute pale 

 scales for the most part placed singly, but in places, especially at the shoulders, and 

 towards the apex of the elytra, forming more or less dense patches.

Niger, capite strigoso et punctato. Antennarum articulus secundus et tertius 

 subaequilongi. Elytra opaca, pube inconspicua et brevissima vestita, seriatim punctata,

 (Plate VII. fig. 3.) 



Black, the antennae, tibiae, and tarsi sometimes with a reddish tinge. The head is 

 strigose and punctured, the antennae have the second and third joints nearly equal in 

 length, the apical joint of the club is evidently shorter than its basal one. The thorax 

 is densely punctured, and has a small pale pubescent spot on each side at the base. 

 The elytra are quite dull, each with about a dozen regular rows of punctures dorsally, 

 and clothed with an excessively short pubescence, usually hardly visible without close 

 examination, but in some examples sufficient to give the surface a slightly greyish 

 appearance. The interstices are furnished with minute scattered tubercles, which are 

 slightly less dull than the general surface. The intermediate and posterior femora have 

 a distinct patch of pale pubescence outwardly.

(5) Rhyncogonus viinor, sp. nov. 



Niger, parum nitidus, capite pubescentia pallida parcius vestito. Antennarum 

 articulus secundus tertio vix longior. Prothorax utrinque linea pubescentiae pallidae 

 continua ornatus. Elytra, humeris et parte apicali exceptis, baud pubescentia. ?. 

 Long. io'5 mm. 



In general sculpture this species bears a strong resemblance to the preceding, but it 

 is a much smaller insect and it is comparatively less elongate. The pubescence of the 

 elytra is confined to some scanty patches at the extreme base, and a very sparse clothing 

 on the apical portion. Their surface is evidently less dull, and except towards the 

 sides and apex there are no evident minute tubercles on the interstices. Their form 

 is different, for they are much more suddenly narrowed to the apex, the narrowing 

 beginning only about one-third of their length from the apex. The front of the head 

 is evidently more pubescent, and there is a wide and distinct stripe of pubescence on
