142 Mr. T. V, Wollaston on certain Coleojpteroxis Insects 



scapo brevissiiiio robiLsto, apice clavato ; fumculo 7-articulato brevi, 

 art" Imo magno valde incrassato subquadrato, reUqiiis miuutis brevis- 

 simis transversis, lougitudine latitudiueque paulatim vJx crescentibus, 

 ultimo clavse baud arete adpresso 5 capitulo solido abrupto subgloboso, 

 obscure 4-annulato. Pedes subgraciles, anteriores basi approximati, 

 postici parum distantes : feniorihus muticis : tihiis (fig. 1 c) rectis gra- 

 cilibus, ad apicem externum in imcum magnum acutissimum inflexum 

 producds : tar sis pseudotetrameris gracilibus elongatis, articulo ultimo 

 elongato clavato unguicidis simplicibus mimito.

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, apicaUy uncinate tibise, and its unreceived tarsi, 

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

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

 thick and sub triangular rostrum, in its very abbreviated and differ- 

 ently constnxcted antennae (which have apparently no lateral scrohs 

 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 un characterized insects 

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

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

 but in them the funiculus is, likewise, hexamerous, the antennae and 

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

 apparent. 



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



S. subcylindrica, nigro-picea, fere calva, subnitidaj capite prothoraceque 

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

 aequali postice recte truncato immarginato, pone medium ad latera 

 subrecto sed ibidem paulo sinuato; elytris piceis striato-punctatis et 

 rugose seriatim asperatis, asperitate antice plicaturas trausversas postice 

 tubercula parva acuta efFormante, interstitiis minutissime punctulatis ; 

 antennis pedibusque piceis, illarum capitulo horumque tarsis pallidio- 

 ribus. 



Long. Corp. l|^-2. 



Several specimens of this curious insect were captured by Mr. 

 Bewicke, but under what circiunstances I have no information.
