202 FAUNA HAWAIIENSIS 



(35) Proterhimis adehis, sp. nov. 



Elongatus, parum convexus, nigricans, vel subobscure rufescens, elytris rufis, nigro- 

 variegatis. Antennae modice elongatae, graciles, clava distincte 3-articulata, basim 

 versus rufae. Vertex capitis a fronte baud divisus. Oculi vix magni, sed fortiter 

 prominentes. Pronotum minus dense squamosum, antice angustatum, et profunde 

 impressum. Elytra basim versus subangustata, maculatim pallide squamosa, parte 

 basali rufa, postice nigro-maculata, setis erectis parce et parum conspicue vestita, dorso 

 parum convexo, basi leviter arcuatim emarginata, humeris distinctis. Abdominis seg- 

 mentum primum ventrale fortiter ubique punctatum, suturis ventralibus sat profundis. 

 cT?. Long, circiter 3 mm. 



Of this apparently distinct species only a single pair, $ and ?, were taken. Apart 

 from the usual sexual differences they are very similar, except that the </ being some- 

 what abraded, has lost nearly all the curved setae from the sides of the thorax (which 

 appears less abruptly narrowed in front), as well as the erect ones from the elytra. 

 Otherwise it differs only in having the thorax and legs redder in colour, and the eyes 

 slightly, but quite evidently, larger. 



Hab. Oahu. A pair were taken in the Koolau range at an elevation of 2500 ft. 

 in the winter of 1892. 



(36) ProterJiinus obscuricolor, sp. nov. 



Nigricans, maculatim squamoso-vestitus, antennis pedibusque obscuricoloribus, 

 P. vestito forma et magnitudine simillimus. Antennae ? graciles, clava minus abrupte 

 3-articulata. Pronotum minus dense squamosum, rugoso-punctatum, 3-impressum, 

 impressione anteriore magis profundo et majore, antice angustatum, haud abrupte 

 fortiterque constrictum, lateribus sat rotundatis, setisque curvatis ciliatis. Elytra 

 maculatim squamosa, setisque pallidis erectis gracilibus conspicue vestita, basi emar- 

 ginata, angulis humeralibus distinctis. %. Long. 2-25 — 3 mm. 



Allied to P. vestitiis, but differing in colour, the shape of the prothorax, &c. 

 The elytra are black, with a somewhat vague humeral or subhumeral spot of pale 

 squamosity, and some other roundish spots behind these ; at the base they are formed 

 much as in typical vcstitiis. A single female only of this species was taken, but there 

 are two males in Dr Sharp's collection, which no doubt belong to the same. They 

 differ from the ? in their antennae being shorter, and the club more distinct (i.e. the 

 9th joint is more stout in proportion to the preceding), and they are considerably
