Habitat Maderenses (Mad., Des.), et Canarienses (Ten.), in subinfe- 

 rioribus intermediisque hinc inde vulgare. 



An insect of Mediterranean latitudes which in all probability will 

 be found to be widely spread over these Atlantic islands. In the 

 Madeiran Group I have taken it (at a rather low elevation) in the 

 south and east of Madeira proper and abundantly on the Deserta 

 Grande ; but from the Canaries I have seen hitherto only a single 

 example which was captured by the Messrs. Crotch, " amongst 

 rubbish, in a cave, at Ycod el Alto," in Teneriffe.

 , Id., Cat. Mad. Col. 142 (1857). 



Habitat Maderenses (Mad.), in intermediis editioribusque sylvaticis 

 humidis parce occurrens. 



A rather large and apterous Corylophus which has been observed 

 hitherto only in the moist sylvan districts of Madeira proper, where 

 it occurs very sparingly at intermediate and lofty elevations. 



Genus 83. ORTHOPERUS. 



Stephens, HI. Brit. Ent. ii. 186 (1829). 



266. Orthoperus atomus. 



Cryptophagus atomus, Gyll., Ins. Suec. i. 185 (1808). 

 Orthoperus atomus, Wott., Cat. Mad. Col. 144 (1857). 

 , Duval, Gen. des Col. tfEur. ii. 236 (1859). 



Habitat Maderenses (Mad.), plerumque ad muros domuum internes 

 rarissimus. 



The European 0. atomus is found sparingly on the inner walls of 

 houses and outhouses in Madeira proper, particularly when in a 

 damp and neglected state a mode of life which is precisely similar 

 to that which it usually leads in our own country.
