CANARIAN COLEOPXERA. 333 



Habitat in Lanzarota ct Fuerteventura, sub lapidibus in arenosis 

 vulgaris : etiam in TenerifFa (in ipsa urbe Sanctse Crucis) specimen 

 unum deprehendi. 



I cannot detect any real difference between the Canarian specimens 

 which I refer to the above insect and the ordinary British ones, — 

 though, since the species is so exceedingly variable both in the colour 

 of its scales and in the greater or less development of its fascia3, cer- 

 tain extreme individuals if taJcen alone might almost have been re- 

 garded as distinct. Nevertheless out of 58 examples now before me 

 (hardly two of which are precisely alike) I seem to have all the va- 

 rieties which are indicated amongst my English specimens ; and I 

 have therefore no hesitation in identifying the whole of them with 

 the European O. limatus. It is an insect which has exactly the same 

 habits as the Rhytidorhinns hrevitarsis, with which indeed it is usually 

 found in company. I have captured it in similar spots both in Lan- 

 zarote and Fuerteventura, namely beneath scoriae — within the holes 

 and inequalities of which it is apt to secrete itself, and out of which 

 it is often difficult to extract it^ It would appear to exist in Tene- 

 riffe also, for I once met with a single example of it in S''' Cruz.

523. Rhytidorhinus brevitarsis, n, sp. 



R. subovato-oblongus, squamis fuscis et albido-fuscis densissime ne- 

 bulosus ; rostro profunde canaliculate, ad basin bituberculato ; pro- 

 thorace valde inaequah, in dorso late canaliculato, utrinque profun-

 dato-ampliato, postice angustiore ; elytris obsolete nigro-irroratis, 

 profunde punctato-striatis (pimctis magnis), sutura intcrstitiisque 

 alternis costato-elevatis, pra^scrtim ante apicem (desilientem) no- 

 des efficientibus; an tennis pedibusque brevibus, illis rufo-piceis, his

Habitat Lanzarotam et Fuerteventuram, in iisdem locis ac Crronops 

 lunatus degens : sub scoriis in arenosis aridis hinc inde abundat. 



The present Rhytidorhinus is very closely allied to two species now 

 before me, which were taken by the Rev. Hamlet Clark in the south 

 of Spain, particularly however to one of them (which may perhaps 

 be the crispatus, Schon.). Nevertheless from both it may immediately 

 be recognized by its shorter antennae and legs, the tarsi especially 

 having the basal and apical joints much more abbreviated — a struc-
