paruin fortiter sinuatis. Tarsorum anticoriun avticulus qiiartiis minus tbrtiter 

 lobatus, posticorum tantuiu siibleviter emarginatus. Abdominis segmentum 

 ultimum venfrale $ setis utrinque tribus munitum. Long. 7"5 mm. 



Hab. In montibus insulae Molokaiae altioribus et humidis meuse Februario 

 1902 captus. 



Ohs. This remarkable species appears to be unlike any described 

 Atelothrus, but rather to resemble such species as Metromcnus audax 

 (described below) and M. latifrons or some species of Mesothriscus. 

 Though the j^i'oiiotal setae are wanting, the punctures or papillae, 

 where they wei'e inserted, are quite conspicuous. 



3. — Atelothrus dehilis, sp. n. 



Angustus, elongatiis, fernigineus, capite plus minusve ini'usc-ato, pedibus, 

 antennis palpisque tiavescentibus. Caput nilidum, oculis parum forliter con- 

 vexis. Pronotnm fere aeqiia longum ac latum, vix transversinn, angulis 

 aiiterioribus parum fortiter productis, posterioribus fere rectis. Elytra nee 

 nitida, nee fortiter striata. Tarsorum anterioruui articulus quartus parvus, 

 ttTtio minor, baud lobatus. Long. G'5 mm. ; lat. elytrorum vix 2-5 mm. 



Hab. In Haleakala, monte Mauiensi, ad altitudinem pedum 3000 multis 

 ante annia captus. 



Ohs. Allied to A. longicoUis Sharp, but not much more than half the 

 size of a specimen of that species with which I have compared it. The 

 pronotum by actual measurement is a little less long (in the middle line) 

 than its greatest breadth, though it has an elongate appearance, the 

 elyti-a are dull and less deeply striate, the eyes considerably less convex, 

 a character which at once separates it from most of the other species of 

 the genus. 



4. — Atelothrus fractistriatus, sp. n. 



Piceo-niger, nitidus, elytris nigris, pedibus rufesceutibus, antennarum basi 

 pallide rufa. Caput nitidura, oculis sat fortiter couvexis. Pronotum nitidum, 

 trausversum, aut baud elongatum, lateribus subaequaliter curvatis, margine 

 postico et antico fere aequilatis, hoc parum emargiuato. Elytra anterius 

 subtiliter striata, fortiter conspicueque utrinque suturam versus lineatim 

 trifoveata, striis nonnullis posterius irregularibus sive intenuptis, serie 

 fovearum striae exterioris permagnarura fortiter impressa. Tarsorum anti- 

 corum et intermediorum articulus quartus profunde lobatim fissus. Long. 

 5*75-6"5 mm. 



Hab. In montibus Oahuensibus Honolulu juxta et alibi, plerumque supra 

 duo millia ped. alt. captus, nee frequens. 



Obs. This species appears to be out of place in Atelothrus, but I 

 can suggest no other more suitable. The shoulders of tlie elytra are
