over these Atlantic islands, where it is very probably universal. 

 Nevertheless hitherto it has been observed only in Madeira proper 

 and Porto Santo, of the Madeiran Group, and in Lanzarote, Teneriffe, 

 and Palma, of the Canaries. It is recorded also at the Azores, and 

 was captured by the late Mr. Bewicke even at St. Helena. 



Genus 27. CALATHUS. 

 Bonelli, Observ. Ent. i. tab. syn. (1809). 



I. Tibice in utroque sexu (omnitio vel fere) simplices. 



a. Corpus magnum, prothorace postice plus minus anyustiore, punctis 



elytrorum discalibus obsoletis. 



74. Calathus sphodroides. 



Calathus sphodroides, Wall, Ann. Nat. Hist. ix. 342 (1862). 

 , Id., Cat. Can. Col. 30 (1864). 



Habitat Canarienses (Ten.), in lauretis humidis editioribus prassertiin 

 sub cortice laxo putrido rarissimus. 



Hitherto I have observed this fine Calathus only in the laurel- 

 regions of Teneriffe, where it occurs (though very sparingly) at 

 intermediate and lofty altitudes. 



75. Calathus acuminatus. 



Calathus acuminatus, Wott., Ann. Nat. Hist. ix. 342 (1862). 

 f id., Cat. Can. Col. 31 (1864). 



Habitat Canarienses (Ten.), in sylvaticis humidis editioribus hinc 

 inde haud infrequens. 



Likewise a Canarian Calathus, and peculiar (so far as observed 

 hitherto) to the moist sylvan districts of Teneriffe at a high elevation. 

 In such places it is not particularly uncommon, though, on account 

 of their being more or less difficult of access, the species must be 

 regarded practically as rare. 



b. Corpus minoris mciynitudims, prothorace postice (ut in Calathis 

 typicis) plus minus latiore, punctis elytrorum discalibus plus minus 

 distinctis. 



76. Calathus rufocastaneus. 



Calathus rufocastaueus, Woll., Ann. Nat. Hist. ix. 343 (1862). 

 , Id., Cat. Can. Col. 31 (1864). 



Habitat Canarienses (Ten.), in locis similibus ac praecedens rarissimus. 



Inhabits much the same regions as the last two species, being 

 apparently peculiar to the damp wooded parts of Teneriffe. It is
