6o8 FAUNA HAWAIIENSIS 



(41) Xylctobins praeccps, sp. nov. , 



Niger aut fusco-niger, pedibus antennarumque articulis 3 basalibus aut compluribus 

 rufescentibus aut flavescentibus. Caput albido-tomentosum, antennis brevibus, articulis 

 4 — g latis. Pronotum, desuper visum, medium nigro-fusco-tomentosum, lateribus 

 dense albido-tomentosis, margine antico versus angulos laterales sat fortiter (nonnun- 

 quam angulariter) explanato sive prominente. Elytra nigro-fusco-tomentosa, hinc illic 

 plus minus ferrugineo- aut aureo-nitentia, lateribus tomento argenteo (plus minus aureo 

 commixto) vestitis. Long. 3'5 mm. 



Evidently allied to X. sykesii and its allies, the elytra shorter than in most of these 

 and less uneven. Tomentum for the most part dark fuscous with golden or ferruginous 

 reflections, but silver or mixed silvery and golden on the sides of the pronotum and of 

 the elytra. Pronotum angulate at the sides or almost so, in dorsal aspect, owing to the 

 anterior margin being explanate before attaining the lateral angles. 



I have seen but two examples taken together in June 1S96, one of which is more 

 slender and only half the bulk of the other, though probably both are females. They 

 are obviously of the same species and otherwise differ very little except in minute details 

 of vestiture. The pronotum is much smoother and the colour of the clothing utterly 

 unlike that of A', sykesii violokaiensis, which is found in the same locality, while the 

 elytra also are not conspicuously impressed.

(42) Xylctobins luiindiis, sp. nov. 



Brunneo- sive fusco-niger, capite cinereo-tomentoso, pronoto elytrisque tomento 

 simili fusco, aureo-micante, vestitis, horum lateribus dense argenteo-tomentosis, pedibus 

 flavis, antennis articulis nonnullis basalibus rufescentibus. Long. 3 mm. 



Evidently closely allied to X. sykesii, but very different in superficial appearance 

 from the dark fuscous tomentum on the pronotum, resembling that on the elytra and the 

 other differences in the latter, as noted in the diag^nosis. The anterior marg^in of the 

 pronotum near the lateral angles is strongly prominently rounded or explanate, of the 

 same general form as that of A', sykesii. The three or four joints preceding the terminal 

 one of the antennae are more elongate than in any examples of that species. It is 

 however possible that it may prove a local form of X. sykesii, although that insect in 

 its typical condition or in one rather ajjproaching the var. molokaiensis is found 

 on Oahu. 



Hab. Oahu, about 2000 ft. One example only taken.
