45. Sphodrus leucophthalmiis. 



Carabus leucophthalmiis, Linn., Fiia Suee. 784 (ITCl). 

 Sphodrus planus, Ckdro., Ent. Helv. ii. 86 ( 1806). 



, Dej., Spec. Gen. des Col. iii. 88 (1828). 



leucophthalmus, Schamn, Nat. der Ins. Deiitsch. i. 381 (1860). 



Habitat Lanzarotara, rariss., forsan ex Europa introductiis. 



The common European S. leucophthalmus occurs in Lanzarote, 

 though very sparingly ; where it was captured by Mr. Gray and my- 

 self, in the vicinity of Arrecife, during January 1858. 



Genus 20. PRISTONYCHUS. 

 Dejean, Spec. Gen. des Col. iii. 43 (1828). 



46. Pristonychus alternans. 



Pristonychus alternans, DeJ., Spec. Gen. des Col. iii. 61 (1828). 

 Sphodrus alternans, Brulle, in Webb et Berth. (Col.) pi. ii. f. 8 (1838). 



Habitat Teneriffain, pra^sertim in montibus, sed hand frequens. 



The large and distinct P. alternans, so remarkable for its flattened, 

 opake, alutaceous elytra (which are acuminated at their apex, and 

 have their alternate interstices more or less impressed with large 

 and deep punctures), is widely scattered, though sparingly, through- 

 out the intermediate and higher elevations of Teneriife. I have 

 taken it on the ascent of the mountains immediately behind S'^ Cruz, 

 at an elevation of scarcely m-ore than about 600 or 700 feet ; as also 

 on the lofty Cumbre adjoining the Caiiadas, at an altitude of at least 

 7000 feet above the sea. It has also been sent to me from Teneriffe 

 by the Barao do Castello de Paiva. 



47. Pristonychus complanatus. 



Pristonychus complanatus, Dej., Spec. Gen. des Col. iii. 58 (1828). 

 Sphodrus complanatus, Brulle, in WM et Berth. (Col.) 56 (1838). 

 Pristonychus alatus, Woll, Ins. Mad. 27 (1854). 

 , Id., Cat. Mad. Col. 11 (1857). 



Habitat in Lanzarota, Teneriffa et Palma, hinc inde sub lapidibus 

 necnon in cavernis tufse latitans. 



Although nowhere abundant, the P. complanatus of Mediterranean 

 latitudes is widely distributed over the Cianarian archipelago, and 

 wiU probably be found to be universal. At present, however, I have 

 only observed it in Lanzarote, Teneriffe, and Palma (in the second of 

 which it was also taken by Dr. Crotch and the Barao do Castello de 

 Paiva). It occurs in Madeira and Porto Santo, and is recorded by 

 M. Morelet at the Azores ; and it was found by Mr. Bewicke even 

 at St. Helena : so that it would appear to be very general through- 

 out the Atlantic islands.
