would retain them at present as a subdivision of Atlantis, to which the larger of 

 their representatives in general aspect a good deal approximate.

277. Atlantis clavatus, Woll. (Tab. VII. fig. 3.) 



A. subelliptico-ovatus gracilis piceo-niger, pube fulvescenti-brunnea depressa variegatus, oculis parvis 

 valde promineDtibus, prothorace (prsesertim autice) angusto crebre punctate, elytris punctato- 

 striatis obsolete undulato-insequalibus, liumeris leviter porrectis, interstitiis fulvescenti-subfasci- 

 culato-tessellatis, antennis pedibusque infuscato-testaceis, illarum articulis secundo et tertio sub- 

 sequalibus. 

 Mas adhuc latet. 



Fcem., pedibus gracilibus simplicibus. 

 Long. Corp. lin. 3|-. 



Habitat in montibus IMaderse, rarissimus; — a meipso sub lapide in deseensu a fastigio "Pouso" ad 

 campum excelsum ilium Fateiras dictum, tempore vernali a.d. 1848, semel tantum repertus. 



Insectum antennarum structura Laparocero sat affine, sed babitu cum Atlantide potius convenit : ex 

 unico tamen specimine, fceminco, vix satis de genere adjudicare licet. An igitur genus novum 

 constituat egomet affirmare nequeo, sed Atlantidi affinitate generali proximum videtur. 



A. subelliptical-ovate, and slender, being somewhat acute both before and behind, piceous-black, and 

 clothed (though apparently not very densely) with a decumbent fulvescent-, or slightly golden- 

 brown pubescence. Rostrum a little longer and slenderer than in any of the other species, and 

 (as in them) slightly dilated at its apex ; rugosely punctm-ed ; and with a very abbreviated longi- 

 tudinal channel between the eijes, — which are small, perfectly round, and exceedingly prominent. 

 Prothorax very much narrower than the elytra, widest behind the middle ; densely and rather 

 coarsely punctured. Elytra ovate, but much truncated at the base, the humeral angles being 

 slightly porrected ; the surface rather undulated or uneven ; punctate-striated ; entirely free from 

 the elongated, suberect additional hairs which are so evident in nearly all the other species ; the 

 suture more densely and uniformly clothed, and the interstices (especially the alternate ones) 

 longitudinally tessellated, with pale fulvescent-, or somewhat golden-brown pubescence. Antenna 

 and legs testaceous, though a little infuscated in parts ; the former with the first and second 

 joints of their funiculus equal, and with their club slender and elongate-oblong ; the latter with 

 the clau'S black. 



Male, hitherto undiscovered. 



Female, with the legs exceedingly slender, and simple. 



As already stated, the present insect, on account of a female example having 

 been alone discovered, is one of extremely doubtful location, and will perhaps form 

 the type, eventually, of a distinct genus. At any rate, it cannot be a tvue Atlantis, 

 regarding that group as limited to the seven species which constitute the first 

 portion of the second of the sections into which I have distributed the entire 

 number, — the construction of its antennae, in which it is coincident with Laparo-
