COLEOPTERA 221 



(74) Protcrliinus separandus, sp. nov. 



Rufescens, capite, thorace (plus minusve), antennis, femoribusque obscurioribus. 

 Capitis vertex a fronte baud divisus. Oculi magni, fortiter prominentes. Antennae 

 subgraciles, articulo primo crasso et brevi, clava distincte 3-articulata, baud notabili. 

 Pronotum pallide squamosum, antice abrupte constrictum et transversim impressum, 

 impressionibus posterioribus minus distinctis, dense rugoso-punctatum. Elytra griseo- 

 squamosa, sparsim nigro-maculata, obscurius longitudinaliter carinata, basi extrema 

 bituberculata, humeris productis. Femora sat fortiter incrassata, lobis tarsorum anti- 

 corum sat magnis. $. Long. 3'2 mm. 



This species is quite distinct from any other species known on Maui, but is very 

 closely allied to the Oahuan P. ruficornis. The single J example described above is 

 probably somewhat abraded, but there are evident erect pale setae still remaining on the 

 elytra. There is no trace of a ridge between the front and vertex of the head, and the 

 eyes are very large and strongly prominent. The antennae are not very slender, their 

 basal joint is very short and stout, the second slightly longer than wide, the third about 

 twice as long as this, the club is distinctly formed by three joints, but is not unusually 

 elongate or in any way remarkable. This will easily distinguish the species from the 

 Oahuan P. ruficornis, which has the club very strongly developed, its basal joint being 

 more than usually elongate, very narrow at the base and much widened at the apex. 

 Basal segment of the abdomen beneath rather strongly punctured, evenly at the sides, 

 the puncturation becoming obsolete about the middle. Coxae rather less widely 

 separated than in most of the species. 



Hab. Maui. A single example taken in the lao valley in March, 1S94 ; and one 

 from the mountains of Molokai in 1893 may perhaps belong to the same species. 



(75) Protcrhimis mactilatns, sp. nov. 



Rufescens, femoribus nigricantibus, elytris nigro-maculatis. Antennae graciles, 

 rufae, clava vix plus quam 2-articulata. Oculi minores. Pronotum squamosum, 

 medium sat latum, antice fortiter abrupte constrictum, fortiter 3-impressum, lateribus 

 setis curvatis conspicue marginatis. Elytra maculatim squamosa, setisque erectis 

 pallidis parcius vestita, linea obliqua pallide squamosa posthumerali maculisque 

 rotundis compluribus postice ornata, basi emarginata, humeris distinctis, vel productis. 

 Femora omnia fortiter incrassata. Abdominis segmentum primum ventrale fortiter 

 sed minus dense punctatum. $%. Long. 2*6 — 3 mm. 



I have seen only two examples of this species, and the ? is so different to the 

 $ in form, owing to the extreme elongation of its elytra, as at first sight to appear
