COLEOPTERA 609 



(43) Xvlctobius aurifcr, sp. nov. 



Piceus aut fusco-niger, antennarum articulis basalibus pedibusque flavis aut rufes- 

 centibus. A', sykesii affinis, sed minus ang-ustus, elytris pronotoque tomento aureo 

 concolori vestitis, illis minus fortiter impressis distinguendus. Long. 3 mm. 



Shorter and wider than A', svkcsii (typical), the pronotum much less uneven than 

 in the var. molokaiensis, the clothing of tomentum more uniform in colour, this form is 

 at present to be regarded as a distinct species. Nevertheless future observations may 

 prove it to be no more than a constantly occurring variation of A', sykcsii, some examples 

 of which evidently approach it more closely than others. 



Hab. Hawaii, Kilauea. 



(44) Xv/t'/o/>i)is chryseis, sp. nov. 



Parvus, elongatus, angustus, dense aureo et fusco-aureo tomento vestitus, pedibus 

 antennarumque articulis basalibus flavis aut ruhs, antennis brevibus. Margo pronoti, 

 desuper visi, anticus juxta angulos laterales fortius prominulus sive explanatus. Elytris 

 minus fortiter inaequalibus. Long. 2 '3 mm. 



Closely allied to X. sykesii but smaller, the surface less uneven and consequently 

 appearing more regularly clothed. Pronotum in dorsal aspect with the front margin 

 rather strongly prominent or explanate at the sides. The tomentose covering is more 

 like X. aurifer than that of sykesii, but the former is at once separated by its much 

 wider form. 



H.AB. Oahu, Waianae mountains, about 2000 ft. I have only seen half a dozen 

 examples, obtained together and showing no variation. 



(45) Xviciobiits scotti, sp. nov. 



X. sikcsii subsimilis, angustus, parvus, tomento argenteo aut pallide aureo vestitus, 

 nigricans aut fusco-niger, pedibus pallidis, tlavescentibus, antennarum 2 aut 3 articulis 

 basalibus flavis aut rufis, pronoto antice, nonnunquam etiam postice, rufescente, elytris 

 juxta humeros supra rufomaculatis. Antennae sat breves, articulo sexto et sequentibus 

 aut transversis aut parum elongatis (maris quam feminae paullo longioribus). Pronotum, 

 desuper adspectum, fere simplex, lateribus levissime concavis, hand subfortiter quasi 

 excisis, margine antico versus angulos laterales haud evidenter prominulo sive explanato. 

 Elytra et pronotum tomento fere simili colore vestita. Long. 3 mm. 



The tomentum on the elytra, as in A', sikcsii and its allies, is conspicuously 

 irregular, some of the short hairs of which it is composed being directed transversely 

 inwards, some outwards, while some are longitudinal in direction, some of the striae 

 a good deal sinuate at the elytral impressions. The species is quite distinct from any of
