22 CANAEIAN COLEOPTERA. 



little Tarus (the elytral portion of which appears almost undulated), 

 in conjunction with its densely and subrugosely sculptured head and 

 prothorax, and the rather evident punctures of its (often interrupted) 

 striae, will readily distinguish it. Its legs are of a slightly paler hue 

 than those of the three preceding species ; the fine, erect pubescence 

 with which it is clothed is very short ; and its elytra are but obscurely 

 diluted, or siihrufescent, towards the edges and base. It is certainly 

 rare, and appears to be pecidiar to the sylvan regions of TeneriflFe, 

 at intermediate and rather lofty elevations. I have taken it in the 

 woods above Taganana and at Las Mercedes, as also at the Agua 

 Garcia and the Agua Mansa. Its general outline and uneven surface 

 are strongly suggestive of a minute Zargus ; from which fact I have 

 borrowed its trivial name ; and, according to Dr. Schaum, it is nearer, 

 in affinity, to the T. cordatiis, Eambur, than to any other species 

 hitherto described. 



Genus 14. MASOREUS. 

 (Ziegler) Dej., Spec. GH. dcs Col. iii. 538 (1828). 



35. Masoreus nobilis, n. sp. 

 M. magnus, pieeus ; capitc prothoraceque nitidissimis, vix (etiam 

 oculo valdc armato) alutaceis, hoc leviter canaliculato ; elytris alu- 

 taceis, sat profimde crenato-striatis, fere concoloribus (ad humeros 

 vix rufescentioribus) ; antennis, palpis pedibusque rufo-piceis ; un- 

 guiculis fere simplicibus. — Long. corp. lin. 2|-3^. 



Habitat in Fuerteventura, ad Olivam d. 31. Mart. a.d. 1859 captus. 



The comparatively large size of this gigantic Masoreus, in conjunc- 

 tion with its almost uniformly piceous (or rufo-pieeous) hue, the un- 

 alutaceous surface of its head and prothorax, its somewhat deeply 

 crenate-striated elytra, and its nearly simple claws, will at once 

 characterize it. The only three specimens which I have seen were 

 captured by myself, from beneath stones, in the flat ground imme- 

 diately to the south of Oliva, in Fuerteventura, on the 31st of March 



1859. 



36. Masoreus arenicola. 



M. nigro-piceus, distincte (oculo armato) alutaceus; prothorace trans- 

 verso, subconvexo, postice in medio plus minus conspicue trans- 

 versim impresso sed vix rugato, canalicula centrali hand profunda 

 necnon antice et postice plus minus subobsoleta ; elytris leviter 

 subcrenato-striatis, ad basin plus minus distincte rufescentioribus ; 

 antennis, palpis pedibusque piceo-tcstaceis; imguiculis leviter den- 

 ticulatis. — Long. corp. lin. 2-2^.
