with outstanding curved setae quite conspicuous ; the posterior foveae or 

 impressions sometimes indistinct, sometimes entirely wanting. 



Elytra long, sparsely clothed, so that the coarse close punctures are 

 easily seen, the clothing consisting of very minute setae, and of longer 

 erect pallid ones, these also being short. Humeral angles distinct and 

 produced, the tubercles at the base, on each side of the scutellar region, 

 are verj^ little developed, but their position is rendered evident by a con- 

 densation of clothing on their surface, forming a pair of small but 

 noticeable spots, distinct from the general vestiture. The femora, and 

 tibiae may be either red or dark. The basal abdominal segment is dis- 

 tinctly punctate on the disc, microscopically sculptured between tlie punc- 

 tures. Length, male and female, 2.5-3.5 mm. 



Hab. jMaui, Kaleakala (August 29, 1918, Swezey) ; de- 

 scribed from 26 of the 27 examples captured on the dead leaves 

 at the bases of the rare and very local Composite plant, Argy- 

 roxlpliium virescens, growing in a small canyon a little above 

 Pun ISTianiau. 



Proterhinus cuneatus n. sp. 



Head and thorax obscure red. witii golden clothing, the elytra red 

 with the covering whitish, this being nearly uniform except on the black 

 spots, which are bare and situated mostly near the middle of the wing- 

 cases. The elytra are widest at the base, the sides almost straightly 

 converging from the shoulders. 



IMost like P. molokaicnsis. probably an even rather larger species, 

 with long antennae, but at the same time the elongate funicle joints are 

 much stouter than is usual in the genus and rather resemble those of 

 the species just named. 



Eyes large and very convex, the head strongly constricted behind 

 them, so that a strong ridge is formed there, though less evident in the 

 middle. Scape of antennae long and robustly subtriangular, the second 

 joint elongate, as long as the fourth and much stouter, all the funicle 

 joints elongate, the seventh antennal joint being twice as long as its 

 apical width and the eighth very much longer than wide. The rounded 

 sides of the pronotum are set with quite conspicuous curved setae and 

 very greatly narrowed anteriorly ; the anterior impression is very large 

 and though deep is vague, the posterior pair are roundish, very deep 

 and distinct. Humeral angles of the elytra very strongly produced, the 

 tubercles on either side of the scutellum also produced, but less strongly, 

 and bearing a spot formed bj^ whitish setae ; the punctures are deep but 

 not at all dense on the basal portion of the elytra. The erect setae are 

 white, long and slender, very conspicuous, being more numerous than 

 usual. Femora dark, the tibiae red. tarsal lobes not large for the size 

 of the insect. Lengtii, male. 4.5 nun.
