lb CANAEIAN COLEOPTERA. 



ad basin, tibiis tarsisque plus minus piceo-fuscis. — Long. corj). lin. 



Habitat Lanzarotam (proesertim borealem), sub lapidibus, passim. 



As already implied, the somewhat more shining, and rather less 

 coarsely alutaceous, surface of the present MetahJetus, in conjunction 

 with its slightly more convex, less uneven, and more obsoletely stri- 

 ated elytra (which have the fovea;, both of their disk and sides, dis- 

 tinctly smaller), will serve to separate it from the M. inaquaUs. 

 In habits, too, it is different from that species, being confined (so far 

 as I have observed hitherto) to the dry and barren island of Lanza- 

 rote, — where, dui'ing January of 1858 and March of the following 

 year, I took it, not uncommonly, from beneath stones, in various 

 localities ; and where it was likewise captured by Mr. Gray. 



28. Metabletus brevipennis, n. sp. 



M. incequali similis sed vix minor, pallidior (?'. e. magis fuscescens), 

 opacior (^. e. paulo grossius alutaceus) ; fronte inter oculos magis 

 deprcssa ; prothorace sensim quadratiore {l. e. postice vix minus 

 angustato) ; elytris magis aequalibus, densius et multo levins (sc. 

 levissime) striatis punctisque duobus discalibus multo minoribus 

 notatis, brevioribus (apice magis truncatis) ; antennis pedibusque 

 palHdioribus (rufo-brunneis). — Long. corp. lin. 1|. 



Habitat Teneriffam, a W. D. Crotch tempore vernali a.d. 1862 de- 

 prehensus. 



The specimen from which the above diagnosis has been compiled 

 was captured by Dr. Crotch, during the spring of 1862, in Tenerifte ; 

 and although unwilling to erect a species on the evidence afforded 

 by a single individual, yet its distinctive characters appear to be so 

 well defined that I cannot but venture in the present instance to do 

 so. Judging therefore from the unique example now before me, the 

 M, brevipennis is slightly smaller, paler (or of a more brownish- 

 piceous tint), and less shining (or more coarsely alutaceous) than the 

 incequalis ; its forehead is rather fiatter between the eyes ; its pro- 

 thorax is just perceptibly squarer (or less narrowed posteriorly) ; its 

 elytra are much more even, more closely and very much more lightly 

 striated, considerably shorter (or more truncated behind), and with 

 the two discal punctures on each smaller ; and its limbs are paler, 

 being of a rufo-piceous or reddish-brown hue.
