Holcobms jnajor S\\dir\i, Tr. Ent. Soc. London, iS8i, p. 521. 

 Varies somewhat in size and in the colour of the antennae. 

 Hab. Maui: Halealcala, 4000 — 5000 ft. (Blackburn, Perkins). 



(2) Holcobius siiiiulans, sp. nov. 



H. majori forma colore et magnitudine simillimus, sed pronoto toto opaco, 

 distincte subtiliter sculpturato, interstitiis parum convexis facile distinguendus. Long. 

 10 mm. 



The antennae in the single example are nearly black, excepting the apical joints. 

 The sculpture of the pronotum is extremely fine and dense on the disc, where are a few 

 shallow punctures, the surface very dull, the elytral interstices seem to be even flatter 

 than those of H. major. 



Hab. Maui : Haleakala, 5000 ft., but not taken with H. major. 



(3) Holcobius insignis, sp. nov. 



Statura majore, nigricans, robustus, opacus, antennis plus minus testaceis. 

 Pronotum dense aureo-pubescens, granulatum, lateribus, desuper aspectis, antice quasi 

 emarginatis. Elytra fusco-pubescentia, subfortiter striata, striis punctatis, interstitiis 

 convexiusculis. Long, i i mm. 



Much more robust than H. major and H. simulans and with the thorax very 

 densely clothed all over with golden pubescence. Punctures on the striae coarser than 

 in most of the allied species, but difficult to see, unless denuded. 



Hab. Kauai ; 4000 ft. ; one specimen. 



(4) Holcobius halcakalae, sp. nov. 



Sordide niger aut fusco-niger, opacus, dense fusco-pubescens, pube sub-aureomi- 

 cante, antennis tarsisque (ex parte) testaceis. Antennarum articulus 9 ultimo evidenter 

 brevior. Pronotum totum peropacum, subtiliter granulatum, lateribus quasi emarginatis.
