472 FAUNA HAWAIIENSIS 



(21) Enpetimis diibins, sp. nov. 



Latus, brevis, fusco-testaceus, marginibus pedibusque testaceis, leviter nitidus, tenue 

 pubescens ; prothorace fortiter transverse, ad latera conspicue explanato, lateribus rotun- 

 datis, angulis posterioribus obtusis, sat rare sed argute punctate ; elytris late explanatis, 

 inaequalibus ; sulcis haud profundis, punctatis ; interstitiis latis laevibusque ; abdomine 

 sat rare punctate. Long. corp. 2,\ — 3a """T"- I l^t. corp. circa \h mm. 



This species is distinguished from E. lanaiensis by its smaller size, and greater 

 proportionate breadth. The punctuations on the prothorax are further apart ; the 

 interstices of the elytra broad and smooth, without the transverse striations of E. lanai- 

 ensis and E. niarginatus, and giving a more shining appearance to this species. The 

 punctuations on the abdomen are less numerous, the pubescence is delicate. 



The male supplementary segment tapers somewhat, and is rounded at the apex ; 

 in one specimen of the dimidiatus form it is blunter, subtruncate. Male pygidium 

 truncate with rounded angles ; female pygidium broader, more or less rounded. 



Van dimidiatus ; this form is present in both sexes. Sixteen specimens. 



Hab. Lanai. Halepaakai, vii. 1894 (no. 134); 2000 — 3000 feet (nos. 80, "$>"], 92, 

 93, Perkins). H. S. 



Eupetinus dubius, var. ? 



A single male of the dimidiatus form from Oahu (near Honolulu, 2000 ft., no. 61, 

 Perkins) resembles E. dubius, but has the thorax longer and less narrowed in front. 



There is also a very immature female from Oahu (iv. 1901, no. 750, Perkins), 

 with broad margins to the elytra ; the thorax differs in shape from that of E. dubius ; 

 the species is quite uncertain. 



(22) Eupetijius brevicornis, sp. nov. 



Sat latus, nigricans, marginibus testaceis, pedibus antennarumque basi fusco- 

 testaceis ; antennis brevibus ; prothorace fortiter transverso, ad latera conspicue 

 explanato, antrorsum fortiter posteriusque parum angustato, angulis posterioribus argutis, 

 crebre punctato ; elytris impressis, ad latera late explanatis, sulcis punctatis, interstitiis 

 haud latis ; abdomine crebre punctato, parum conspicue pubescente. Long. corp. 3^^ mm. ; 

 lat. corp. i^ mm. 



A single female from Lanai is close to E. dubius, but differs in the shape and 

 punctuation of the prothorax ; in having the conspicuously shortened antennae ; and 

 in being more closely punctuated and coarsely pubescent ; especially on the abdomen. 

 These characters render it quite distinct. The pygidium is coarsely punctuated. 



Hab. Lanai, 3000 ft., 11. 1894 (Perkins). H. S.
