CARABID^E. 



is extremely rare, for in spite of their careful researches three 

 specimens only were obtained ; and moreover it is peculiarly inter- 

 esting, as introducing the (hitherto Madeiran) genus of which it is 

 a member into the Canarian fauna. I have had much pleasure in 

 naming it after my friend Mr. G. R. Crotch, to whose investigations 

 (in conjunction with those of his brother) I am so greatly indebted 

 for the majority of the species described in the Appendix to this 

 volume. 



68. Zargus Monizii. 

 Zargus Monizii, Wott., Ann. Nat. Hist. v. 217 (1860). 



Habitat Maderenses (Mad.), rarissimus ; a cl. Moniz in inferioribus 

 repertus. 



Discovered in Madeira proper by Senhor Moniz, who met with 

 several examples of it (during December 1858) on the cindery slope 

 behind the sea-beach in the little bay immediately within the Cabo 

 Garajao, or Brazen Head. It is possible that it may be but an ex- 

 tremely developed state of the Z. pellucidus, its larger size and 

 darker hue being the principal characters which separate it from 

 that species. 



69. Zargus pellucidus. 



Zargus pellucidus, Wott., Ins. Mad. 25, tab. i, f. 6 (1854). 

 y 2d., Cat. Mad. Col. 11 (1857). 



Habitat Maderenses (Mad., Des.), late diffusus sed rarissimus. 



Inhabits Madeira proper and the Deserta Grande, occurring 

 sparingly at most elevations. 



Genus 25. SPHODRTJS. 

 Clairville, JEnt. Helv. ii. 86 (1806). 



70. Sphodrus leucophthalmus. 



Carabus leucophthalmus, Linn., Fna Suec. 784 (1761). 

 Sphodrus leucophthalmus, Clairv., Ent. Helv. ii. 86 (1806). 



, Schaum, Nat. der Ins. Deutsch. i. 381 (1860). 



, Wott., Cat. Can. Col. 29 (1864). 



Habitat Canarienses (Lanz.) rarissimus; forsan ex Europa introductus. 



This common European insect is found in Lanzarote, of the Cana- 

 rian Group, where, however, it is extremely rare. Possibly it may 

 have been introduced accidentally from more northern latitudes, 

 since it occurs for the most part near the towns.
