external contour it must be admitted that it is most anomalous, pre- 

 senting such an exact resemblance to the ordinary Curculionidce (as, 

 for instance, some of the Atlantic Cydomides, such as Atlantis and 

 Laparocerus). that it is scarcely possible at first sight to help associ- 

 ating it with the members of that family. It is on this very account, 

 however, peculiarly interesting ; for, if there had been any doubt as 

 to the real affinity of the Orthocerous and Gonatocerous divisions of 

 the Rhynchophora, assuredly such a genus as Notioxenus, which com- 

 bines the structural features of the former with the almost precise 

 outward likeness of the latter, would have gone far to dispel it. 



10. Notioxenus Bewichii, n. sp. (PI. XIV. fig. 1.) 



N. fusco-niger, subopacus, impunctatus, squamulis fuscis dense tectus et 

 cinereis parce pictus ; protborace linea sub-basali impressa curvata notato 

 et plagis tribus longitudinalibus cinereo-squamosis obscure picto ; elytris 

 impimctato-striatis, maculis minutis plurimis cinereo-squamosis irro- 

 ratis ; antennis fuscis, basi rufo-testaceis ; pedibus fusco-piceis, genibus 

 rufescentioribus, tarsia picescenti-testaceis.

A single specimen of this extraordinary insect was taken by Mr. 

 Bewicke ; and I have much pleasure in dedicating it to its captor, 

 to whose researches we are indebted for the several novelties de- 

 scribed in the present paper. At first sight it has much the outline 

 and colouring of a Madeiran or Canarian Atlantis, — its dark-brown, 

 densely- clothed surface, relieved only by small and indistinct patches 

 of dull cinereous scales, somewhat calling to mind certain members 

 of that group. Not to mention many other characters, its almost 

 impunctate, though rather alutaceous and subopake surface (which, 

 however, can only be perceived when the pubescence is removed), 

 in conjunction with its unpunctured elytral strise, and its deeply- 

 impressed and curved sub-basal prothoracic line, deserve to be espe- 

 cially noticed. 



11. Notioxenus rufopictus, n. sp. (PI. XIV. fig. 2.) 



N. piceo-ater, nitidus, subglaber; protborace striga sub-basali elevata 

 minus curvata notato, profunde et dense punctato ; elytris profunde 

 crenato-striatis, interstitiis convexis, parce, minutissime et irregulariter 

 punctulatis, maculis parvis plurimis (prgesertim ad basin et versus 

 latera) rufis vel rufo-testaceis (plus minus confluentibus) ornatis; 

 antennis fuscis, basi rufo-testaceis ; pedibus nigro-piceis, femoribus 

 versus apicem genibusque rufescentioribus, tarsis picescenti-testaceis.
