Notioxenus Bewickii, Well., loc. cit. 213, pi. xiv. f. 1 (18G1). 

 A most remarkable species, differing from the other Notioxeyii 

 hitherto detected not only in its much larger size and in its 

 griseoiis-black, densely clothed surface, which appears to be 

 obscurely ornamented with small and indistinct dull cinereous 

 patches, but likewise (which is an extremely anomalous fea- 

 ture) in its subbasal prothoracic line being imjjressed^ instead 

 of raised. With the exception of the head, which is more 

 coarsely sculptured, its surface is impunctate, though rather 

 alutaceous and subopaque (as may be seen when the pubes- 

 cence is removed) ; and its elytral strias are also perfectly 

 simple. The only two examples of this Notioxenus which 

 have yet come under my notice were taken — one, in 1860, 

 by the late Mr. Bewicke (to whom the species is dedicated), 

 '' amongst native vegetation on the extreme summit of the 

 island," and the other, more recently, by Mr. Melliss.

54. Notioxenus rnfopictus. 



N. ater, nitidus, subcalvus (se. pube brevi demissa fulvo-cinerea 

 parcissime irroratus) ; capite prothoraceque sat rugulose punc- 

 tatis, bujus linea subbasali elevata subrecta (i. e. utrinque vix 

 curvata) ; elytris profunde crenato-striatis, interstitiis convexis, 

 parce, minutissime et irregulariter punctulatis, maculis parvis 

 plurimis (pra3sertim ad' basin et versus latera) rufis aut testaceo- 

 rufis (plus minus confluentibus) ornatis; antennis breviusculis, 

 rufu-testaceis, apicem versus infuscatis ; pedibus nigro-piceis, 

 femoribus apicem versus genibusque rufescentioribus, tarsis pices- 

 .centi-testaceis.

Notioxenus rufopidus, Woll., loc. cit. 213, pi. xiv. f. 2 (1861). 



The only example of this beautiful Notioxenus Avhich I have 



yet seen was captured by the late Mr. Bewicke, during his 



few hours' collecting at St. Helena, on the 21st of July 18G0, 



amongst native vegetation, on the extreme summit of tbe
