COLEOPTERA 127 



(11) Rhyncogomis kaiiaiensis, sp. nov. 



Niger, vel plus minusve rufescens, capita et corpore toto subtiliter griseo- vel rufo- 

 pubescente. Caput strigosum et punctatum. Prothorax dense punctatus, utrinque vitta 

 pubescente ornatus. Elytra vix opaca, subtiliter pubescentia. Long. 10 — 13 mm. 



Colour varying from black to reddish brown. The male generally much depressed, 

 the % more convex, but neither sex is constant in this respect. Head more or less 

 strigose and punctured, clothed all over with fine pale hairs, which form a denser line 

 around the inner margins of the eyes. Thorax densely punctured, clothed with fine 

 pubescence like that of the head, and on each side with a line of dense pale pubescence. 

 Elytra usually more or less shining, but much duller in some examples than others, 

 clothed with fine grey or reddish pubescence, the series of punctures for the most part 

 distinct, but towards the sides becoming more or less confused, and the surface more or 

 less rough, often tuberculate. The pseudepipleural region of the elytra always with 

 conspicuous patches or spots of dense pubescence. 



Hab. Kauai (4000 ft.) ; 15 examples taken. Apparently a very variable species. 



(12) Rhyncogomis sordidus, sp. nov. 



Niger, vel subrufescens, opacus, subtiliter pubescens, capite punctate. Prothorax 

 dense nee grosse punctatus. Elytra opaca, pubescentia, seriatim punctata, lateribus 

 maculis pubescentibus haud ornatis. $%■ Long. 10 — 12 mm. 



The colour of this species varies from black to obscure red. The front of the head 

 and rostrum is almost without pubescence, the puncturation of the latter is usually not 

 very close and it shows little or no trace of longitudinal strigosity, its surface is more or 

 less flattened or depressed. The thorax is densely, but not coarsely, punctured, more 

 or less impressed near the base, clothed with very short and fine pubescence, and with 

 a line of denser and rather longer hairs on each side, but even in fresh examples these 

 lines are obscure. The elytra have a very fine pubescence, which is more conspicuous 

 in the ?, and of a reddish colour. Their surface is dull, but not rough, and the 

 punctures towards the sides remain quite distinct, although the series may be more or 

 less confused. On their deflexed portion there is no trace of spots or lines of dense 

 pubescence, such as are found in the preceding species. In the ^ the apical ventral 

 segment only of the hind-body is densely hairy, the others but sparsely so, the two 

 basal more or less strongly impressed. 



Hab. Lanai, mountains (3000 ft.). A short and rather variable series taken. 

 The relative length of the second and third joints of the antennae appears to vary, as 

 also the puncturation of the insect. Fragments of a Rhyncogomis found on Molokai 

 are probably referable to this species. In one spot these were very abundant, but the 

 species had no doubt been extinct (so far as that particular locality is concerned) for 

 years, the vegetation consisting only of small stunted bushes.
