598 FAUNA HAWAIIENSIS 



notum if viewed from the side, has its tipper outline a Httle sinuate, not simply curved 

 or convex. This is due to the lateral impressions extending right across the pronotum, 

 but the character is much less marked than in well-developed specimens of X. stdcatus, 

 of which this is so characteristic a feature. The subapical joints of the antennae of the 

 male, though strongly elongate, are not so slender as is usual in males of this group. 

 What I believe to be the female has much shorter antennae, the eighth joint evidently 

 elongate, the two preceding hardly or not at all so.

(21) Xyleiobiits ashuieadi, sp. no v. 



Niger, plerumque minus dense griseo-tomentosus, elytris ante media rufo-fasciatis, 

 fascia lateraliter elytrorum basim attingente, post media rufo-bimaculatis. Tibiae nigri- 

 cantes aut piceae. Antennarum articulus secundus (aliique hujus vicini nonnunquam) 

 rufus. Caput subtiliter granulatim sculpturatum, oculis mediocribus, late separatis. 

 Antennae elongatae, maris toto corpore paullo breviores aut saltern elytris evidenter 

 sat longiores, feminae elytris nonnihil breviores, articulo secundo parvo, subgloboso, 

 tertio intus distincte angulato, quarto pro longitudine sequentibus latiore, haud tamen 

 transverso, caeteris versus apices antennarum longitudine accrescentibus, cunctis (prae- 

 sertim $) elongatis. Pronoti latera desuper visa quasi emarginata, pronoto a latere 

 viso supra fere aequaliter conve.xo. Elytra leviter striata, stria secunda plerumque 

 cum quinta confluente, et tertiam quartamque includente, haudquaquam cum tertia sola 

 apicaliter conjuncta. Long. 3 mm. 



This species is easily recognized by its general appearance. The tomentum is 

 usually more or less flavescent on the red markings of the elytra, and is pretty evenly 

 distributed, so as to give the insect a generally smooth appearance. The five or six 

 terminal joints of the antennae are very elongate, more strongly in the $ than in the $, 

 and they become more slender towards the apex of the antennae.

Nigricans aut fusco-niger, capite pronotique lateribus pallide tomentosis, anten- 

 narum articulis 2 aut 3 basalibus rufis, tibiis laete testaceis aut rufescentibus, elytris 

 trans basim nigricantibus aut nigro-fuscis, tum fascia transversa pallide tomentosa, post 

 hanc nigricantibus aut nigro-fuscis, apicibus plus minusve pallido tomento ornatis. 

 Caput obscurius granulatum, oculis mediocribus, maris late distantibus, spatio, quod 

 interest, una conjunctis latioribus, antennis sat elongatis, ^-is elytris longitudine 

 aequalibus, ?-ae elytris paullo brevioribus, articulis 5 apicalibus sat fortiter elongatis. 

 Pronotum, a latere visum, supra convexum, parum inaequale. Elytra subtiliter striata, 

 stria secunda cum tertia sola apicaliter haud confluente, sed saepe cum quinta conjuncta, 

 et tertiam quartamque includente. Long. 3 mm.
