CANARIAN COLEOPTERA. 323 



ratively even (being but slightly impressed on either side, and with 

 a small shallow fovea down the centre in front — immediately behind 

 which there is a very minute, abbreviated, and slender discal keel) ; 

 and its elytra, which are but finely punctate-striate, are hardly at 

 all produced (separately) at their extreme apices. 



The C. Armitagii may be presumed to be extremely rare ; and it 

 is, therefore, the more remarkable that it should have been acciden- 

 tally met with by Mr. Armitage during his few days' sojourn in 

 Tenerifl^e. 



510. Cleonus variolosus, n. sp. 



C. tahido et excoriato affinis, sed magis cylindricus, rostro minus alte 

 carinato ; prothorace longiore, subcylindrico, magis aequali sed 

 profunde varioloso-punctato (variolis maximis, remotis, plus minus 

 subconfluentibus), basi in medio multo minus ante scutellum pro- 

 ducto (fere simplieiter rotundato) ; elytris subcylindricis, seriatim 

 (vix striato-) punctatis (punctis maximis) sed fcro absque lacunis, 

 ftisciis duabus brevibus transversis nigris minus oblique atquc hand 

 conicis ornatis, ante apicem minus constrictis necnon act apicem 

 ipsum singulatim obtusioribus (?'. e. singulis minus acuminatis) ; 

 pedibus sensim robustioribus. — Long. corp. lin. 5-6. 



Habitat in arenosis inferioribus Fuerteventurae, rarissimus : etiam 

 in insula parva " Lobos " dicta exemplar unicum collegi. 



Of the present Cleonus I have seen but two examples, — one of 

 which was taken by myself in a low sandy spot close to Puerto de 

 Cabras in Fuerteventura, and the other on the little rock of Lobos off 

 the extreme north of that island. It is allied to the C. tahklus and 

 e.vcoi'iatiis*, but is more cylindrical, with its prothorax longer and 

 less uneven (though more deeply pitted with enormous, but remote, 

 punctures or varioles), and very much less produced in the centre 

 behind, and with its elytra (which are obtuser, or less constricted, 

 posteriorly, and very much less separately-acuminated at their ex- 

 treme apices) more coarsely punctured though less deeply striated, 

 with their two dark fasciae more developed but less regular or defined, 

 less conical and less oblique, and with the elongate longitudinal im- 

 pressions (or lacunae) which are so conspicuous in that species almost, 

 or entirely, obsolete. Its legs, likewise, are a trifle more robust ; and 

 the keel of its rostrum is not quite so elevated. 



* M. Jekel, after examining the present insect, wrote to me as follows: "It is 

 fl. new Cleonus belonging to the group oi excoriatns, erlcw, &c., much allied to an 

 unde.scribed species from the south of Spain {gaditanus, Rambur, in lift), and 

 so closely related to another from Barbary (likewise unjDublished), in Mr. Bow- 

 ring's collection, that I am inclined to regard the two as but varieties of a single 

 species."
