6o4 FAUNA HAWAIIENSIS 



(33) Xyletobius nudus, sp, no\'. 



Niger, baud robustus, antennis pedibusque nigris, subtilissime, parum conspicue, 

 cinereo-tomentosLis. Caput parum pubescens, dense subtilissime sculpturatum, antennis 

 longitudine mediocribus, fortiter intus serratis, articulis 3, 4, 5 et 6 transversis, aut 

 saltern haud longioribus quam latioribus, 7 et 8 fere aeque latis ac longis aut paullulo 

 elongatis, 9 et 10 sat conspicue longioribus quam latioribus. Pronotum subnitidum, 

 laeve, subtilissime punctulatum, subtilissime nee dense tomentosum, fortiter transversum, 

 antice distincte marginatum. Elytra subtiliter striata, striis fere impunctatis, distincte 

 sinuatis, interstitiis crebre rugulosis, stria secunda cum tertia ad apices confluente, 

 tomento albido minus conspicuo, sculpturam elytrorum haud celante. Long. 4 mm. 



I think this species must be closely allied to X. nigrinus Sharp, which I have not 

 examined, but it does not agree in detail with Dr Sharp's full description of that species, 

 and is, I should think, clearly distinct. It is not closely allied to any other known to 

 me. I have seen only the type (which I believe to be a male) and one other example. 

 The latter has the pronotum less strongly transverse and more produced in the middle 

 in front, but is clearly the same species, agreeing in other respects with the type. 



Hab. Kauai ; 3000 and 4000 ft. 



(34) Xyletobius speiseri, sp. nov. 



Fuscus, antennis fusco-testaceis sive brunneis, pedibus brunneo-testaceis, ubique 

 aequaliter tomentosus. Caput dense tomentosum, antennis brevibus, articulis 3 ante- 

 apicalibus minus fortiter elongatis, haud bis longioribus quam latioribus. Oculi majores, 

 sed late distantes. Pronotum latum, plaga dorsali dense aequaliter brunneo-tomentosa, 

 hac plaga utrinque albido-marginata, latera versus cinereo-tomentosum. Elytra utrin- 

 que sat evidenter compressa, plaga brunnea dorsali magna subtriangulari (sive postice 

 attenuata) post mediam suturam extensa, utrinque albomarginata, ornata, apicibus latius 

 aureo-brunneis, partibus caeteris cinereo-tomentosis, stria secunda cum tertia sola haud 

 confluente. Long, vix 5 mm. 



I have seen only one example of this species, probably a male. It was taken at 

 light. It is allied only to A', collingei, but is very distinct.

(35) Xyletobuts col Huge i, sp. nov. 



Fusco-niger aut fusco-rufus, antennis nigricantibus, articulis basalibus haud, aut 

 parum distincte, rufescentibus. Antennae conspicue breves, articulis intermediis haud, 

 apicalibus minus fortiter, elongatis. Pronotum dense granulatim sculpturatum, pero- 

 pacum, tomento fusco-pallido aut pallido vestitum, maculis compluribus, plus minus 

 distinctis, quasi nudioribus signatum. Elytra albido-tomentosa, plaga dorsali permagna,
