CURCULIONID^. 



Gronops lunatus, Schon., Gen. et Spec. Cure. ii. 253 (1834). 

 , WolL, Cat. Can. Col. 332 (1864). 



Habitat Canarienses (Lanz., Fuert., Ten.}, sub lapidibus scoriisque 

 in aridis iiiferioribus submaritimis hinc inde congregans. 



The common European G. lunatus, although extremely local, is 

 occasionally abundant in Lanzarote and Fuerteventura the two 

 eastern islands of the Canarian Group, where it congregates beneath 

 stones and scoriae in low arid spots near the coast. It seems^to exist 

 likewise, though much more rarely, in Teneriffe ; for I captured a 

 single specimen of it in one of the streets at S ta Cruz. 



Genus 266. RHYTIDORHINUS. 

 Schonherr, Cure. Disp. Meth. 162 [script. Rhytirhynus] (1826). 



849. Rhytidorhinus brevitarsis. 



Rhytidorhinus brevitarsis, WolL, Cat. Can. Col. 333 (1864). 



Habitat Canarienses (Lanz., Fuert.), in iisdem locis ac Gronops lu- 

 natus. 



Found in Lanzarote and Puerteventura, in precisely the same 

 kind of places as the Gronops lunatus indeed often in company 

 with it ; and I met with it even on the little island of Lobos, off the 

 extreme north of the latter. It is closely allied to the R. crispatus 

 from the south of Spain, and may be regarded as the Canarian repre- 

 sentative of that insect; nevertheless its shorter limbs (the tarsi 

 especially being very much more abbreviated) will, apart from minor 

 differences, at once separate it therefrom. 



(Subfam. XXI. BRACHYCEKIDES.) 



Genus 267. BRACHYCERUS. 

 Fabricius, Syst. Eleu. ii. 412 (1801). 



850. Brachycerus opacus. 



Brachycerus opacus, Well., Cat. Can. Col. 334 (1864). 

 Habitat Canarienses (Lanz.}, rarissimus ; semel tantum repertus. 



A Canarian Brachycerus of excessive rarity, a single specimen 

 which I obtained (on the hills above Haria) in the north of Lan- 

 zarote being all that I have yet seen of it. It is, moreover, the only 

 member of the genus which has been detected hitherto in these 

 Atlantic islands.
