34. Dromius plagipennis. 



Dromius plagipennis, WolL, Append, hnj. op. 3. 

 Habitat Canarienses (Ten., Hierro), in intermediis rarissimus. 



This large Dromius was detected by the Messrs. Crotch in Tene- 

 rifie and Hierro, during tlieir late Canarian campaign where it 

 seems to be very rare and confined to intermediate altitudes. It 

 has apparently a close affinity with the D. meridionalis of southern. 

 Europe. 



35. Dromius alutaceus. 

 Dromius alutaceus, WolL, Cat. Mad. Col. 2 (1857). 



Habitat Maderenses (Mad.), sub cortice laxo praesertim Ericce et 

 Tasci in intermediis parce degens. 



Although extremely local, not very uncommon in certain places in 

 Madeira proper harbouring principally beneath the bark of yew 

 trees, and the dry outer fibre of heaths, at intermediate altitudes. 

 In such situations it has been taken at " the Mount " (above 

 Funchal), at Camacha, and at S. Antonio da Serra. It belongs to 

 the same type as the last species, to which indeed (although unques- 

 tionably distinct from it) it is closely allied *. 



36. Dromius oceanicus. 



Dromius insularis (p.), WolL, Ins. Mad. 4 (1854). 



(p.), Id., Cat. Mad. Col. 2 (1857). 



oceanicus, Id., Append, huj. op. 3. 



Habitat Maderenses (Chao, Des.), sub lapidibus in aridis rarissimus. 



Observed hitherto only on the Northern and Central Desertas (i. e. 

 the Ilheo Chao and the Deserta Grande) of the Madeiran Group, 

 where it occurs (though very rarely) beneath stones in arid spots. 



37. Dromius insularis. 



Dromius insularis, WolL, Ins. Mad. 4 (1854). 



, Id., Cat. Mad. Col. 2 (1857).

Habitat Maderenses (Mad.), in sylvaticis humidis editioribus sub 

 cortice laxo praecipue latitans. 



* In the D. alutaceus the head and prothorax (the former of which is a little 

 rounder, or more suddenly narrowed behind the eyes, whilst the latter is a trifle 

 smaller and more quadrate) are less shining than in the plagipennis, being in 

 fact alutaceous (though less coarsely so than the elytra), and the pale blotch on- 

 the fore part of each elytron is so increased in length as to cover the larger por- 

 tion of either disk. The entire insect also is somewhat smaller and slenderer, 

 and its elytra are straighter at the sides and more depressed.
