592 FAUNA HAWAIIENSIS 



the latter very definitely raised all round, and shining, with elongate antennae, which do 

 not differ greatly in the sexes, though shorter in the female, may be assigned to 

 X. proteus. 



Hab. All the islands, but taken only rarely excepting on Hawaii ; very numerous 

 on that island near the active volcano Kilauea. 



(9) Xyletobuts inesochloriis, sp. nov. 



Nigricans et rufus, sat robustus, forma X. protci, capite, pronotique lateribus 

 densissime pallido-tomentosis. Pronotum antice distinctissime marginatum, margine 

 laevi, nitido. Elytra fusco-nigro tomento vestita, macula magna, mediali et transuturali, 

 pallide-tomentosa ornata, strigisque aut maculis aliis paucis pallidis. Long. 3' 7 5 mm. 



Form and structure very like that of A', proteus, but quite distinct in its clothing 

 from any of the known varieties of that species, and apparently very constant, the five 

 examples taken being closely similar. It reminds one a good deal of the var. dorsalis 

 with the general colour of the elytra and that of the dorsal spot reversed. Perhaps it 

 should be considered as a local race of A', protats rather than a distinct species, though 

 at present it is not connected with the ordinary forms of that insect by any intermediates. 



H.\B. Molokai, singly and rarely, 3000 — 4000 ft. 



(10) Xylefobius nitptus, sp. nov. 



Rufescens, plus minusve nigro- aut fusco-variegatus, antennarum articulis tribus 

 basalibus plerumque rufis, caeteris nigris. Caput sat dense pallide tomentosum, oculis 

 mediocribus, latissime .separatis. Antennae utriusque sexus fortiter elongatae, maris 

 tamen evidenter longiores, articulo septimo circiter bis longiore quam latior. Pronotum 

 latum, antice distinctissime marginatum, lateribus dense pallido-tomentosis, medium 

 evidenter granulatum. Elytra plerumque notis plus minusve elongatis nigris aut fuscis 

 variegata, lateribus versus media saepe macula triangulari aut subtriangulari fusca aut 

 nigra notatis, stria secunda saepe cum quinta ad apicem confluente, haud quaquam cum 

 tertia sola conjuncta. Long, solit. ■ii'i "ti""- 



Xylctohius juiptus var. kaiiaiensis nov. 



It will be convenient to use this name for the Kauai form of the above, even 

 though the two are not definitely separable in all cases. The variation, so far as I can 

 judge from the specimens collected, is very different on Lanai and Kauai, though 

 certain individuals from each island closely resemble one another. In examples from 

 Kauai the dark elytral markings are usually more elongate and sometimes are so 

 extensive that nearly the entire elytra are black. Near their middle there is in many
