COLEOPTERA 233 



(97) Proterhimis le^icothorax, sp. nov. 



Nigro- vel rufo-piceus, pedibus antennarumque basi plus minus rufescentibus. 

 Oculi sat magni, prominuH. Pronotum fortiter 3-impressum, setis appressis squamisque 

 albidis dense vestitum (impressionibus 2 lateralibus densissime squamis albicantibus 

 vestitis), medium postice subsulcatum. Elytra grossissime dense rugoso-punctata, 

 maculis duabus albidis squamosis postice signata, ex majore parte squamis carentia, sed 

 setulis brevibus erectis albidis sat evidenter vestita, sutura distincte elevatula, cariniformi, 

 angulis humeralibus fortiter productis. Femora postica parum fortiter incrassata. ^ $. 

 Long. 2 — 2'25 mm. 



One of the smallest species of those which have the humeral angles of the elytra 

 strongly produced forwards. It is chieHy remarkable for the gross sculpture of the 

 elytra which are nearly free from squamous covering, and especially for the peculiarly 

 dense whitish clothing of the thorax. I see no trace of a transverse ridge between the 

 front and vertex of the head in the t, and only the faintest trace thereof in the %. The 

 species is allied to P. innotabilis. 



Hab. Molokai. Three examples (one of which has lost most of the squamous 

 covering) were taken at an elevation of about 4000 ft. 



(98) Proterliiniis angiistior, sp. nov. 



Subgracilis, nigricans, elytris plus minusve (praecipue basim versus) rufescentibus. 

 Antennae graciliores, minus fortiter elongatae, articulis basalibus plerumque rufescenti- 

 bus, clava 3-articulata. Pronotum baud latissimum, % saepe angustulum, baud dense 

 squamosum, subfortiter 3-impressum. Elytra angustiora, nigricantia, partibus pallidiori- 

 bus (sc. rufescentibus) squamas pallidas ferentibus, setis erectis, elongatis, parce 

 conspersis, sat evidenter vestita, fere aequaliter convexa, basi scutellum juxta utrinque 

 plus minus tuberculata, sutura levissime elevata, humeris fortiter productis. Oculi 

 parum fortiter prominentes. Femora omnia fortiter incrassata, lobis tarsorum anticorum 

 minoribus. t ?• Long. 2-4 — vix 3 mm. 



The affinities of this species are evidently with P. htimeralis of Maui, which 

 in many respects it greatly resembles. All the femora are quite strongly incrassate, 

 very much as in that species, but the antennae, especially those of the t, are much less 

 developed, as also are the eyes and the lobes of the front tarsi. The chief variation 

 exhibited by the seven examples taken lies in the shape of the prothorax, which is a 

 eood deal more dobose in some than in others. No doubt in a long series the tendency 

 would be to a greater elongation generally in the females, as I have observed to be the 

 case with other species. The sides of the rostrum of the ? are slightly convergent 

 from base to apex. 



Hab. Molokai, mountains (3000 ft.).
