COLEOPTERA 267 



Brown, the prothorax with some very fine remote subobsolete punctures, the base of 

 the elytra with some very feebly impressed nearly obsolete but rather large ones. The 

 apical portion of the elytra is of a pale testaceous colour and much paler than the brown 

 basal portion much as in the var. minor. 



Hab. Maui, Haleakala, 5000ft., typical form and the var. minor; also on Molokai 

 above 4000 ft. Rare. 



(5) Apterocis variabilis, sp. nov. 



Nitidus, valde aequaliter convexus, colore variabili, sed elytrorum apice extremo 

 semper pallido. Pronoto distincte subtiliter nee dense punctato, postice haud distincte 

 marginato. Elytra basim versus remote punctata, punctis saepe obsoletis, vix videndis, 

 nonnunquam sat distinctis sed parum profundis. Abdominis segmenta ventralia dense 

 subtiliter punctata. Long. r5 — 2 mm. 



Variable in colour, like A. ephistemoides in form, but of larger average size. Black 

 with the thorax more or less piceous, the apex of the elytra pale and with a reddish spot 

 at either shoulder sometimes united to form a transverse fascia, or entirely reddish-brown, 

 with only the apex of the elytra paler than the general colour, the elytra being a little 

 darker in colour in front of the pale apex, thereby rendering the paleness more distinct. 

 Intermediates occur between the extreme forms. The dark varieties (.^ males) have 

 the thorax more closely punctured, and the puncturation of the basal part of the elytra 

 generally rather large and distinct, although shallow. In the pale forms (? females) the 

 elytral puncturation is often hardly observable, but there is evident variation in this 

 respect. The mesosternum in front of the middle coxae is I believe formed as in 

 A. ephistemoides, so that the front pair are almost contiguous with these. 



Hab. Oahu, Waianae mountains, several examples taken. In some varieties this 

 species greatly resembles A. lanaiensis but the puncturation of the prothorax is not 

 rugulose as in that species, others resemble A. montanus, which has the thorax much less 

 distinctly punctate. 



(6) Apterocis liawaiiensis, sp. nov. 



Niger, nitidus, valde fere aequaliter convexus, elytrorum apice rufescente. Pro- 

 notum nitidum, subtiliter remote punctatum, postice haud evidenter marginatum. 

 Elytra nitida, basali parte praecipue versus latera grossius remote punctata. Meta- 

 sternum et abdominis segmenta ventralia dense punctata ; segmentum basale t tuberculo 

 forti munitum. Mesosternum breve, parte sculpturata praecoxali fortiter obliqua. 

 Long, circa 2 mm.
