CANARIAN COLEOPTERA. 331 



elytra being a trifle less porrect, or more drawn in, at the shoulders. 

 In its general colouring, as well as in the interstices of its elytra 

 being (when the scales are removed) opake and rugulose, and in its 

 more acutely spined femora, it agrc^es best with the P. miisicus ; but 

 in its somewhat shorter and thicker rostrum, as well as in its elytra 

 beiug obtuse and entire at their extremity (instead of separately 

 pointed), it accords better with the velutinus. 



The unique specimen I captured between Guia and Osorio, on the 

 mountains of Gi'and Canary — in the laurel-region (fast decreasing) 

 which represents the ancient forest of El Dorames. 



Genus 208. XENOMICRUS (nov. gen.). 



Genus affinitate cum Liosomate Steph., conjimctum atque illud prima 

 facie simulans, sed corpore parce pubescente (nee glabro),antennis 

 ad (nee pone) apicem (sensim dilatatum) rostri bre\doris crassioris 

 et minus arcuati insertis, oculis majoribus, prothorace cylindrico, 

 scutello conspicue observando pedibusque longioribus gracilioribus 

 certe distinctum vidctiir. 



A ievos, mirabilis, et yuapos, parvus. 



The little Curculionid from which the above structural diagnosis 

 has been drawn out is closely related to Liosomus, with which indeed, 

 until critically examining it, I had supposed it to be congeneric ; 

 nevertheless when acciu-ately inspected it will be seen to difier in 

 most of its details from the members of that group. Thus, it is 

 pubescent (even though minutely and sparingly so), instead of being 

 glabrous ; its rostrum is shorter, thicker, and less arcuated, and is 

 much more expanded at the apex — where the antennee are inserted 

 (instead of at some distance behind it) ; its eyes (although equally 

 sunken) are larger ; its prothorax is cylindrical ; its scutellum is con- 

 spicuous and rounded ; its elytra are inflated and elliptic (being acute, 

 and constricted, at their apex) ; and its legs are rather longer and 



slenderer. 



521. Xenomicrus apionides, n. sp. 



X. piceo-niger elytris subaenescentibus, pube brevi demissa cinerea

 vexis, ad basin singulatim oblique subrotundatis, nitidis, sat pro- 

 funde punctato-striatis, interstitiis uuiseriatim punctatis ; antennis 

 rufo-ferrugineis, ad apicem piceis ; pedibus piceis, tarsis (et inter- 

 dum tibiis) clarioribus ; femoribus simplicibus.
