584 FAUNA HAWAIIENSIS 



Easily distinguished from tiie very closely allied H. granulatiis Sh. by its paler 

 colour and the more conspicuous pubescence. 



Hab. Hawaii, Molokai, Oahu and Kauai. — Hawaii, Kona, 4000 — 6000 ft. ; 

 Molokai, 3000 ft. ; Oahu, 2000 ft. ; Kauai, 4000 ft. ; bred from dead wood of 

 Enpkorlna and often seen flying at dark. 



(8) Holcobiiis Q'raiiulatus Sharp. 



Holcobius granulatus Sharp, Tr. Ent. Soc. London, 1881, p. 520. 



Varies a little in sculpture, the striae being more clearly and largely punctured in 

 some specimens than in others, while the interstices are sometimes slightly convex, 

 sometimes flat. 



Hab. Maui, Hawaii. — Maui, Haleakala, not rare in dead Ohia trees ; Hawaii, 

 Kilauea, one example. 



(9) Holcobius glabricollis Sharp. 



Holcobius glabricollis Sharp, Tr. Ent. Soc. London, 188 1, p. 520. 



Hab. Oahu, Maui. — Oahu, scarce at low elevations in the mountains on Koa 

 trees. Maui, Haleakala, 4000 ft., where one or two examples were taken on Koa, but 

 I do not find these in the collection. I have a note of its occurrence and well remember 

 the fact. 



(10) Holcobius (?) simplex, sp. nov. 



Fusco- aut atro-brunneus, minus opacus, subtiliter pubescens, antennis tarsorumque 

 apicibus testaceis. Pronotum totum subtiliter punctatum, haudquaquam granulatum, 

 lateribus baud quasi-emarginatis. Elytra levius striata, striis anterius punctatis, inter- 

 stitiis crebre et conspicue punctulatis. Long. 5 '5 mm. 



Var. a. Nicer, antennis testaceis. 



Distinguished by the sculpture of the pronotum, the form of th,e palpi, as mentioned 

 in the introductory remarks. The antennal joints are less elongate than those of 

 H. major, haleakalae and divcrsus.

 testaceis (nonnunquam totis vel ex parte obscuricoloribus). Pronotum subtiliter 

 pubescens, vix nitidum, lateribus baud quasi-emarginatis, versus angulos anteriores 

 obsolete granulatim-rugulosum, supra subtilissime punctulatum. Elytra distincte
