COLEOPTERA 



4^3 



(4) Eiipetiiuis siibaper, sp. nov. 



Fusco-ferrugineus plus minusve infuscatus, antennis fuscis, pedibus testaceis, leviter 

 nitidus, vix aeneo-micans, crebre punctatus, vix dense pubescens. E. apro affinis, sed 

 angustior, prothorace ad latera minus rotundato angulisque posterioribus minus argutis ; 

 elytris ad latera minus explanatis. His inaequalibus, sulcis punctatis, interstitiis parum 

 latis transverseque striatis ; abdomine acuminato, pygidio crebre punctate. Long. corp. 

 3 — 4:]:mm. ; lat. corp. i^^ — ij mm. 



This species appears to be very closely allied to both of the two very distinct 

 forms, E. aper and E. omalioides. It differs from the former in the characters 

 mentioned in the diagnosis, and from the latter in those given under the heading of 

 that species ; it has a broader margin to the elytra and is therefore placed at the head 

 of the second section. 



The male supplementary segment is somewhat acuminate, slightly rounded at the 

 sides, fringed with long hairs. The male pygidium is rather narrow at the apex, 

 truncate with rounded angles, slightly emarginate ; female pygidium broader and more 

 rounded. The pygidium in both sexes is much more coarsely punctuated and more 

 pubescent than in E. oiua/ioidcs. The female last ventral segment is fringed with long 

 hairs. 



In both sexes the specimens in colour vary considerably from lighter to darker, 

 and some are of the van dimidiatiis form. 



A single dark male differs from the rest in having its supplementary segment not 

 acuminate but rounded ; in this particular it resembles E. omalioides, but in others, 

 especially in the coarse punctuation of the pygidium, it agrees with E. sitbaper. 

 Ninety-one specimens. 



Hab. Oahu. Apparently found frequently, and sometimes in the same situations 

 as E. omalioides \ Konahuanui Ridge, xii. 1900 (no. 783): many from mountains near 

 Honolulu ; " on strong-smelling introduced creeper " ; " on Pipturus trees " ; " on Pipturus 

 covered with stinking creeper, probably nearly all from the creeper " ; " from a deep 

 dark ravine, on dead plants"; &c. (Perkins). H. S.

The original diagnosis is "Sat latus et elongatus, testaceus, irregulariter plus minus- 

 ve infuscatus, subaeneo-micans, nitidus parce pubescens ; prothorace transverso, an- 

 trorsum vi.x magis quam posterius angustato, disco profunde tri- vel quadri-impresso ; 

 elytris inaequalibus, striatis ; abdomine sat crebre distincte punctato. Long. 3 mm. ; 

 lat. if mm."
