Fam. 9. ANISOTOMID^. 



Genus 74. STEREUS. 

 Wollaston, Cat. Mad. Col. 148 (1857). 



253. Stereus cercyonides. 



Stereus Cercyonides, Woll, op. cit. 149, pi. fig. 1 (1857). 



Habitat Haderenses (Mad.), sub foliis marcidis in lauretis humidis 

 editioribus rarissimus. 



Peculiar to the sylvan regions in Madeira proper, where it bur- 

 rows beneath fallen leaves and other vegetable refuse lying on the 

 damp ground a mode of life for which its robust, spinose tibiae emi- 

 nently fit it. It is extremely rare, and was detected by myself 

 during the summer of 1855 in the laurel- woods at the head of the 

 S to Cruz ravine, at S. Antonio da Serra. And I subsequently met 

 with it, under decaying rubbish, at the Lombarda das Vacas (on the 

 mountains to the east of Sao Vicente). 



Genus 75. ANISOTOMA. 



(Knoch) Ulig., Kaf. Preuss. 69 (1798). 



254. Anisotoma canariensis. 



Anisotoma canariensis, Woll., Ann. Nat. Hist. xi. 216 (1863). 

 , Id., Cat. Can. Col. 98 (1864). 



Habitat Canarienses (Can. ?, Hierro), in intermediis rarissima. 



A small Canarian Anisotoma of great rarity, and of which I cap- 

 tured a few examples in the sylvan district of El Golfo on the western 

 slopes of Hierro. An immature specimen, which I obtained in the 

 region of El Monte in Grand Canary, I believe to be conspecific with 

 the Hierro ones ; but since it is impossible without more satisfactory 

 material to decide this for certain, I have thought it safer to query 

 the occurrence of the species in that island. 



255. Anisotoma oceanica. 

 Anisotoma oceanica, Woll, Cat. Can. Col. 99 (1864). 



Habitat Canarienses (Ten., Gom.), rarissima ; in sylvaticis subedi- 

 tioribus parcissime capta. 



Likewise a Canarian species, and equally scarce with the last one. 

 Indeed only three examples of it have hitherto come beneath my
