338 CANARIAN COLEOPTERA. 



the fact of its outer elytra! interstices being perceptibly (though but 

 a little) raised behind, will all tend to remove it from that species. 

 The single indi\'idual described from was captured by myself, during 

 the spring of 1858, in Grand Canary ; but whether in the district of 

 El Monte or in the Isleta I cannot now exactly recall. 



527. Atlantis tibialis, n. sp. 



A. nigra, subnitida, (oculo fortissime armato) subtilissime et brevis- 

 sime pubescens ; rostro minute et leviter striguloso-subpunctato, 

 late coneavo, canalicula (antice tenui sed postice inter oculos par- 

 vos prominentes profunda foveseformi) impresso ; prothorace pro- 

 funde et dense punctato ; scutello minutissimo ; elytris basi con- 

 junctim subemarginatis, ad humeros oblique rotundatis, profunde 

 punctato-striatis (punctis magnis) ; antennis tarsisque piceo-ferru- 

 gineis ; femoribus tibiisque nigro-piceis. 



Mas vix angustior, tibiis posticis intus ante apicem subito sed leviter 

 rotundato - ampliatis . 



Foem. vix latior, tibiis posticis simplicibus. — Long. corp. lin. 4-5. 



Habitat Teneriffam et Palmam, in inferioribus sub lapidibus, 

 passim. 



This large and black species, so well distinguished by its dull and 

 only slightly shining surface, deeply punctured prothorax, excessively 

 minute scutellum, the enormous punctures of its elytral striae, and 

 by the two hinder tibiae of its male sex being increased, a little be- 

 fore their inner apex, by a slight flattened amplification, or as it were 

 by a small portion suddenly rounded outwards, is apparently not 

 uncommon at low elevations in TenerifFe and Palma. In the former 

 of those islands I have taken it frequently, from beneath stones, in 

 the diy cindery region around the Puerto of Orotava — a locality in 

 which it was likewise found hj Mr. Gray ; whilst in the latter I met 

 with it, in similar situations, in the Barranco immediately above S*" 



Cruz. 



528. Atlantis tetrica. 



A. speciei prsecedenti simihs, sed \dx minor, angustior, nitidior, magis 

 atra et paulo magis glabra ; prothorace sensim convexiore, in disco 

 minus profunde et minus dense punctato (punctis minoribus sub- 

 obsoletis) ; scutello in utroque sexu majore (sed parvo) ; elytris ad 

 basin paulo rectius truncatis, striarum punctis vix minoribus. 



Mas vix angustior, tibiis posticis intus ante apicem latiusculum le- 

 viter excavatis. 



Ff^em. vix latior, tibiis posticis fere simplicibus. — Long. corp. lin.
