52. Metabletus brevipennis. 



Metabletus brevipennis, Wott., Cat. Can. Col. 18 (1864). 

 Habitat Canarienses (Ten.}, rarissimus ; a W. D. Crotch seniel 

 repertus. 



The only specimen which I have yet seen of this Metabletus was 

 taken by Dr. Crotch, during the spring of 1862, in Teneriffe. Its 

 distinctive characters have been fully pointed out in my Canarian 

 Catalogue ; and although apparently well denned, more examples 

 are nevertheless much required in order to ascertain that the features 

 which characterize it as a species are true and constant. 



Genus 18. MASOREUS. 

 (Ziegler) Dej., Spec. Gen. des Col. iii. 538 (1828). 



53. Masoreus nobilis. 



Masoreus nobilis, WolL, Cat. Can. Col. 22 (1864). 

 Habitat Canarienses (Fuert.), rarissimus ; juxta Olivam captus. 



This large Masoreus occurs in Fuerteventura, of the Canarian 

 Group, though very rarely the only three examples which I have 

 seen having been taken by myself, during March 1859, near Oliva. 



54. Masoreus arenicola, 



Masoreus arenicola, JVoll., Ami. Nat. Hist. xi. 214 (1863). 

 , Id., Cat. Can. Col. 22 (1864). 



Habitat Canarienses (Lanz., Fuert.), in areuosis maritimis plus minus 

 salinis hinc inde vulgaris. 



Found in sandy and saline places (on and near the shore) of the 

 two eastern islands of the Canarian Group, Lanzarote and Fuerte- 

 ventura, where it is occasionally abundant. Both it and the M. 

 alticola are closely allied to the European M. Wetterhalii ; but the 

 characters which separate them from that species, as well a& inter se, 

 have been fully pointed out in my Canarian Catalogue. 



55. Masoreus alticola. 



Masoreus alticola, Wott., Cat. Can. Col. 24 (1864). 



Habitat Canarienses (Ten.), rarissimus, in humidis elevatis usque ad 

 8000' s. m. ascendens.
