6io FAUNA HAWAIIENSIS 



these by the more regular pronotal outHne laterally, as described above. The single 

 example from Molokai has the tomentum pale golden, rather than silvery, but otherwise 

 seems identical with three examples from Hawaii, which show no noticeable variation. 

 With these, however, was taken an example of a uniformly brown colour, which may be 

 known as var. casianeus. 



Hab. Molokai, Hawaii. — Hawaii, Kilauea, Molokai, 3000 ft. 



(46) Xylcfobius flosciihis, sp. nov. 



Parvulus, angustus, rufescens, capite nigricante, pedibus antennarumque articulis 

 2 basalibus aut compluribus pallidis, totus aureo tomento aequaliter et laeve vestitus, 

 antennis brevibus. A', ihryscidi cognatissimus. Long. 2'5 mm. 



Allied to A', chryseis, but readily distinguished by the very uniformly distributed 

 pale golden pubescence, the surface of the elytra being smooth, the tomentum not at all 

 rough or shaggy. Elytral striae invisible in perfectly fresh examples, the tomentum 

 concealing them. Pronotum formed as in A', chryseis and allies, the front margin 

 towards the sides a little produced or with a rounded explanation in dorsal aspect. 



Hab. Hawaii, Kilauea; a single example taken on each of three occasions. 



(47) Xyletobuts stcbbingi, sp. nov. 



Minus fortiter angustus, parvulus, niger, dense tomento argenteo aut pallide aureo 

 ubique vestitus, antennis sat brevibus, articulis basalibus pedibusque rubris. Pronotum 

 dense tomentosum, medium postice plaga quasi nuda magna nigricante signatum, 

 margine antico versus angulos laterales haudquaquam explanatim prominulo. Elytra 

 peraequaliter tomentosa, haudquaquam variegata, leviter striata, striis parum fortiter 

 sinuatis. Long. 3 mm. 



Remarkable amongst the species with short antennae for the very uniform and 

 regular clothing of the elytra, on which the tomentum lies in a very even manner, and 

 is neither variegate from differences in colour of the clothing, nor from inequalities of 

 the surface. The pronotum is of a simple form, not appearing excised laterally as in 

 the A', sykesii group, nor with the front margin laterally prominent in dorsal aspect. 

 Three examples taken. 



Xyletobuts stebbingi var. uotatus nov. 



Paullo major, elytris circa aut post media plus minusve fuscescentibus. 



I have seen four examples taken on Molokai, which I refer to this species as a local 

 race or variety. They are not in very good condition, but the tomentum of the elytra 

 is generally slightly darker in tint than in the type form and near or behind the middle
