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

 senting such an exact resemblance to the ordinary Curculionida^ (as, 

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

 Lnparocenis), 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, pecuHarly interesting ; for, if there had been any doubt as 

 to the real affinity of the Orthocerous and Gonatocerous divisions of 

 the Eh>/ncJinj)JiO)'a, assuredly such a genus vlh Notloxenus, which com- 

 bines the structm'al features of the former with the almost precise 

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

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 hj small and indistinct patches 

 of dull cinereous scales, somewhat calling to mind certain members 

 of that group. Xot to mention many other chai-acters, 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 strioe, and its deeply- 

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

 cially noticed. 



11. Notioxenus rufopictns, n. sp. (PI. XIY. fig, 2.) 



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

 minus curvata notato, profunde et dense punctato ; elytris profunde 

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

 punctulatis, maculis parvis plurimis (prfesertim ad basin et versus 

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

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

 versus apicem geuibusque rufescentioribus, tarsis picescenti-testaceis.
