6o2 FAUNA HAWAIIENSIS 



in the other example they are sHghtly smaller. They are clearly closer together than 

 in A', kirkaldyi, just as they are clearly wider apart than those of X. megalops. I should 

 think they represent a distinct species. 



Hab. Oahu. — The type specimen was taken in the Honolulu range at an eleva- 

 tion of somewhat less than 2000 ft. I have since procured the second (mentioned 

 above) some fifteen miles from the original locality. 



(28) Xyletobius hisignis Blackburn. 



Xyletobius insigiiis Blackburn, Tr. Dublin Soc. 1885, p. 158. 



Blackburn's diagnosis is as follows; "Angustus ; dense subtilissime tomentosus ; 

 capite nigro, ore prothoraceque rufis ; elytris piceis testaceo-variegatis subtiliter striatis, 

 striis plus minusve sinuatis ; antennis (toto corpore vix brevioribus), palpis, pedibusque 

 rufis ; oculis permagnis. Long. 5 mm." 



Blackburn, in his further remarks, adds that "the antennae are entirely of a pale 

 red colour." Thousfh this latter character of itself would not be sufficient to define a 

 species, since several Xyletobius present this colour of the antennae as a variation, still 

 I do not feel justified in considering A', msignis as identical with either my A', euops or 

 X. megalops without actual comparison of the types. 



Hab. Hawaii, Kilauea (Blackburn) unique. 



(29) Xyletobms eupliorbiae, sp. nov. 



Oblongus, sat robustus, fusco-niger aut fuscus, partibus nonnunquam rufescentibus, 

 pedibus antennarumque 2 aut 3 articulis basalibus flavidis aut rubris, dense tomentosus. 

 Caput dense pallide tomentosum, oculis latissime separatis, antennis brevibus, articulo 

 sexto et sequentibus haud aut parum elongatis. Pronotum, desuper visum, baud quasi 

 fortiter utrinque excisum, disco brunneo- aut fusco-tomentoso, lateribus dense pallide 

 tomentosis. Elytra latiora, breviuscula, tomento nigro, fuscoque vestita, fascia tomenti 

 cinerei valde curvata aut angulata juxta media elytra suturam attingente, post media 

 fascia secunda transversa cinerea, et post hanc saepius fascia, plus minus distincta, 

 flavescente, interstitiis apices versus convexiusculis. Long. 3 "5 mm. 



This species is very distinct in appearance from any excepting A', cyphus, and does 

 not vary sufficiently to present any difficulty in determination. Its transversely banded 

 elytra, the tomentum forming three or four dark and two or three pale bands, are 

 characteristic. Probably the pale tomentum should be considered the ground colour, 

 and the bands are due to longitudinal apposed markings of dark tomentum on the 

 interstices. The latter are a little raised or convex towards their apices. The granula- 

 tion of the pronotum is very noticeable along the hind margin. 



I have examined a good series of this species, but nearly all of these were bred
