the range and they become scarcer and scarcer, as one conies 

 towards Honolulu, and in no part of this island does one meet 

 with them in the great numbers one finds on the uplands of 

 Hawaii near Kilauea. Holcobius glahricollis is the most inter- 

 esting species and is not rare on Koa trees. Elateridae are 

 represented by the two endemic genera Eopenthes and Itodacnus^ 

 two species of the latter, and not less than six or eight of the 

 former. Tantalus is probably the best known locality for these 

 beetles, which in most places are rare or altogether absent. They 

 are only found during the summer months, and the larvae feed 

 in decaying wood. The beetles are often found feeding in the 

 flowers of the Ohia.in fact are the only Coleopterous insects that 

 visit flowers for the sake of the sweet contents of these. 



About four Eucnemidae of the genus Fornax are known. The 

 larvae are common, but unless collecting systematically one 

 rarely comes across the mature insects. 



There is a single species of the native genus Labrocerus, and it 

 is not at all common and is usually found in company with the 

 Anobiid Xyletobius, which it somewhat closely resembles in 

 superficial appearance. 



The Cucujids Brontolaemus elegans and Laemophloeus aeneus 

 are both found, the former commonly, the latter very rarely. 

 Information as to their life-history is needed, as they seem to 

 have some connection with the various Lon^icorn beetles and 

 their burrows. 



The Colydiid, Antilissus aper is generally found under bark 

 of Straussia with the two Staphylinids Glyptoma blackburni and 

 Lispinodes explicandus. 



The Nitidulidae have two or three species of Gonioryctus and 

 no less than fourteen of Brachypeplus. B. tincius and vestitus on 

 flowers; discedens, parallelus and omaloides on Freycinetiai 

 robustus on Lobeliaceous plants ; guttatus on decayed and exuding 

 Koa; reitteri on banana; infimus on Pisonia; aper on various 

 trees, but not very common ; explanatus, impressus, and inaequalis 

 on several trees and climbing plants ; brevis and a species not yet 

 described under rubbish on the ground in shady places. The 

 Histeridae yield two species at least of Aeletes and one or two 

 smaller beetles, probably Acritus and Bacanius. 



The Staphylinidae have hardly been worked at on Oaha 

 since Blackburn's time, who took many species. One or two
