bulky as others, but ver\' little in general appearance. The female has much shorter 

 antennae, the 6th, "th, Sth and 9th joints being only moderately elongate instead of ver\- 

 stroncflv so.

(iS) Xyleiobius suboculatus, sp. nov. 



Niger aut piceo-niger, antennarum articuHs duobus basalibus rufis, rarius plus 

 minus obfuscatis. pedibus (exceptis nonnunquam anticis) ex majore parte nigricantibus 

 aut obscuricoloribus. Oculi minores, latissime separati. Antennae maris valde, feminae 

 mediocriter, elongatae ; maris articulo sexto fortiter elongate (praecedente multo majore) 

 et longitudine sequentibus minus inaequali. Pronotum basim versus sat fortiter longi- 

 tudinaliter convexum, margine antico medio vix aut parum distincte elevato. opacum, 

 dense subtilissime sculpturatum. Elytra sat elongata et angusta, plus minus lineis 

 tomenti cinerei (plerumque parum conspicue) variegata, rarissime unicoloria. Long. 



2"5— 3'25 mm. 



I have examined about 150 examples of this species minutely, and others more 

 superficially. Amongst these are a few, in which the pronotum in part, or wholly, and 

 sometimes the elytra are red or reddish. In some of these examples the legs too are 

 red or yellow. I sus{>ect that the colour of these specimens is due to immaturit)-, in 

 some it is certainly so. They have much the appearance of some specimens of 

 X. carpenteri and perhaps A", suboculatus should be considered as a local race of that 

 species. If so. the variation of the tAvo forms is entirely difterent. To A', suboctilatus 

 I also refer a few specimens more recently taken on Kauai and Oahu, for I see no 

 characters to distinguish them, in spite of the fact that A', carpenteri is found on the 

 intermediate islands. A', suboculatus is not ver\- variable, as compared with other 

 species. Some examples have but little variegation of the elytra, but this is ver)' rarely, 

 if ever, entirely absent (unless abraded) and when almost absent, the surface is generally 

 covered with a blackish or fuscous tomentum, not with the grey colour of A', ocjilatus. 



Hae. Kauai, Oahu, Hawaii. — Hawaii, Kau and Hilo districts, on Mauna Loa 

 and !Maima Kea.
