410 Mr. T. V. WoUaston 07i the Coleoptera of St. Helena. 



(Subfam. Xantholinides.) 



Genus Xantholinus. 



Dahl, in Encycl. Mahod. x. 475 (1825). 



Xantholmus morto, n. sp. 



X. linearis, niger, nitidus; capite prothoraceque subtilissime alu- 

 taceis, iUo parce fortiter punctato, hujus seriebus dorsalibus e 

 punctis 6-7 compositis ; elytris confuse et laxe subseriatim punc- 

 tatis; antennis piceo-fuscis, art'^ 1™° et 3"° nigrescentioribus ; 

 pedibus nigro-piceis. 



Long. Corp. lin. 2|. 



The single example, taken by Mr. Melliss, from which the 

 above diagnosis is compiled has been carefully examined by 

 Mr. Rye, who remarks that it is unknown to him, but might 

 nevertheless perhaps prove to be the European atratus of 

 Heer. Judging from the description, however, of that spe- 

 cies, it would appear to be not only smaller and blacker than 

 the atratuSy and with darker limbs, but (as I imagine) to have 

 its head more sparingly punctured, and the dorsal punctures 

 of its pro thorax more numerous. In the absence of a type of 

 the atratus from which to form a more decided opinion, I feel 

 that it would be extremely unsafe to identify it with the St.- 

 Helena species, and I have consequently enunciated the latter 

 as above. 



(Subfam. OXYTELIDES.) 



Genus Oxytelus. 



Gravenhorst, Col. Micropt 101 (1802) 



§ I. Antennarum art^ 7 ulteriorihus gradatim incrassatis. 



Oxytelus alutaceifrons^ n. sp. 



0. niger, nitidus, elytris ssepius paulo dilutioribus (plus minus tes- 

 taceo tinctis), pedibus spinulosis saturate testaceis ; capite (sub- 

 triangulari) prothoraceque profunde et dense striguloso-punctatis, 

 illo postice caualiculato, antice in medio impunctato grosse alu- 

 taceo opaco depresso et anguste marginato, oculis prominentibus 

 sed hand magnis, hoc profunde trisulcato, postice angustato; 

 elytris breviusculis, profunde et dense punctato-strigulosis ; an- 

 tennis nigris, basi vix dilutioribus. 



Long. corp. Kn. l|-vix 2. 



An Oxytelus which is in some respects allied to the Euro- 

 pean 0. luteipennis (and less so to the 0. piceus)^ but at the 

 same time differing in many important respects from that 

 species. Thus it is not only a little smaller, rather less 

 shining, and more deeply and closely punctured and strigu- 

 lose, but it is remarkable for its head (instead of being bi-
