98 Mr. D. Sharp on some 



sutures are rather deeper than usual. The dark marks on 

 the elytra are indefinite, and no doubt variable. The 

 species seems to be closer to jP. simplex than to any of 

 the others. 



A pair of this species was sent as No. 164. Mr. Black- 

 burn says it is found in a large fern growing on the Hono- 

 lulu range of mountains. 



ProterJu'nits basalts, n. sp. Latiusculus, pai"um con- 

 vexus, nigricans, setis depressis sat dense irregulariter 

 vestitus, setis erectis sat conspicuis, antennis tibiisque 

 rufo-obscuris ; prothorace latiusculo, anterius breviter con- 

 stricto, basi fortiter angustato, fortiter sed parum discrete 

 punctato, subhispido, tri-impresso ; elytris breviusculis, ad 

 basin transversim depressis, humeris acutis. Long. 3 mm. 



About the size of the largest P. vestitus, and somewhat 

 similar thereto, but broader, and readily distinguished 

 from it, and the other allies, by the depressed basal por- 

 tion of the elytra. The scutellum is more than usually 

 inconspicuous. The antenna? are rather long, and slender. 

 The prosternum, in front of the coxre, is somewhat flat- 

 tened or depressed in the middle, and the vuidersurface is 

 not so rugose as in the allies ; the large basal ventral seg- 

 ment being remarkably free from punctuation. 



Three individuals were beaten from dry sticks, at an 

 elevation of 2,000 feet, on the island of Kauai ; the one 

 sent me is of the rostrate sex, and was No. 166. 



Proterhinus stemiaUs, n. sp. Robustus, breviusculus, 

 nigricans, antennis, femoribus basi, tibiis tarsisque rufis, 

 setis depressis, densins irregulariter vestitus, setis erectis 

 sat conspicuis ; prothorace latiusculo, anterius constricto, 

 rugoso-punctato, tri-impresso ; elytris basi fortiter emar- 

 ginato, parum discrete punctatis, basi summo utrinque 

 prope scutellum subtuberculato, sutura subtilissime cari- 

 nato-elevato, hvimeris prominulis ; prosterno anterius in 

 medio concavo ; tibiis extus longius setosis. Long. 

 2^—3 1 mm. 



This is a very distinct species, though at first sight it 

 seems similar enough to P. vestitus. The eyes are 

 largely developed. The tubercle on each side at the base 

 of the elytra is tomentose like the rest of the surface, and 

 therefore not very cons})icuous ; there is also a very 

 obscure oblique elevation proceeding from each shoulder
