142 Mr. T. V. Wollaston on certain Coleopterous Insects 



scapo brevissimo robusto, apice clavato ; funiculo 7-articulalo brevi, 

 art" l m ° magno valde incrassato subquadrato, reliquis minutis brevis- 

 simis transversis, longitudine latitudineque paulatim vix crescentibus, 

 ultimo clavse haud arete adpresso ; capitulo solido abrupto subgloboso, 

 obscure 4-annulato. Pedes subgraciles, anteriores basi approximate 

 postici parum distautes : femoribus mutieis : tibiis (fig. 1 c) rectis gra- 

 cilibus, ad apicem externum in uncum magnum acutissimum inflexum 

 productis : tarsis pseudotetrameris gracilibus elongatis, articulo ultimo 

 elongato clavato unguiculis simplicibufi munito. 

 A o-revbs angustus, et cr/ceXtj tibia. 



So very closely does the present insect, at first sight, assimilate 

 Hylastes, that I had regarded it, previous to a critical examination, 

 as an abnormal member of that group, in which the external edge 

 of the tibiae were edentate. But, on closer inquiry, it proves to be 

 undoubtedly one of the Curculionidce, the entire structure of its 

 slender, toothless, apically uncinate tibiae, and its unreceived tarsi, 

 assigning it to that family. From Rhyncolus, however, to which it 

 is clearly related, it recedes completely in its excessively short, broad, 

 thick and subtriangular rostrum, in its very abbreviated and differ- 

 ently constructed antennse (which have apparently no lateral scrobs 

 for the reception of their scape), in its minute, punctiform scutellum, 

 its more globose, exposed head, and in its longer feet ; and I should 

 consider that the Madeiran Hexarthrum is perhaps its nearest de- 

 scribed ally, — though in that genus the funiculus is only 6-articulate, 

 whereas in Stenoscelis it is 7-. I have two uncharacterized insects 

 from the Canaries (which reside in the rotten pine-trees of the old 

 Finals of Grand Canary and Teneriffe) to which it is also much akin ; 

 but in them the funiculus is, likewise, hexamerous, the antenna) and 

 rostrum are, both of them, differently formed, and the scrobs is very 

 apparent. 



Stenoscelis hylastoides, n. sp. (Plate XI. fig. 1.) 



& subcylindrica, nigro-picea, fere calva, subnitida ; capite protlioraceque 

 sat profunde et confertissime punctatis, illo convexo sequali, hoc sub- 

 sequali postice recte truncate immarginato, pone medium ad latera 

 subrecto sed ibidem paido sinuate; elytris piceis striato-punctatis et 

 rugose seriatim asperatis, asperitate antice plicaturas transversas postice 

 tubercula parva acuta eiibrmante, interstitiis minutissime punctulatis ; 

 antennis pedibusque piceis, illarum capitido horumque tarsis pallidio- 

 ribus. 



Long. corp. 1^-2. 



Several specimens of this curious insect were captured by Mr. 

 Bewicke, but under what circumstances I have no information.
