Habitat Maderenses (P to S to ), in arenosis maritimis juxta radices 

 Arundinis donacis fodiens parcissime lectus. 



I captured two examples of this minute and widely spread Euro- 

 pean Phytosus, during the spring of 1855, in Porto Santo of the 

 Madeiran Group burrowing into the loose sand, near the roots of 

 Arundo donax, immediately behind the southern beach ; but they 

 are all that I have yet seen from these Atlantic Groups. In my 

 Madeiran Catalogue I referred them to the P. nigriventris ; but they 

 are certainly more correctly identified with the balticus, an insect 

 which (like most of the strictly maritime species) seems to have a 

 rather wide geographical range occurring in northern Europe, and 

 being (according to Fauvel) very abundant on the coasts of France. 

 It may be known from its ally by being smaller and narrower and 

 altogether less pallid (or of a more infuscated, reddish-brown hue), 

 by having its elytra more parallel (or not at all widened posteriorly), 

 its abdomen less opake, more sparingly punctured, and nearly con- 

 colorous with the rest of the surface (the postmedial segments being 

 only a trifle more clouded than the remainder), and its limbs per- 

 ceptibly shorter, or less developed. 



Genus 380. PHLCEOPORA.

1250. Phloeopora corticina. 

 Phlceopora corticina, Wott., Cat. Can. Col. 533 (1864). 



Habitat Canarienses (Ten., Gom., Palma, Hierro), sub cortice arborum 

 in sylvaticis intermediis latens. 



Found usually at rather lofty altitudes in the Canarian Group, 

 occurring beneath the bark of trees. I have taken it in Teneriffe 

 and Palma ; and two specimens are now before me which were cap- 

 tured by the Messrs. Crotch, respectively, in Gomera and Hierro. 

 It is somewhat intermediate between the European P. reptans and 

 corticalis, and might perhaps be a geographical modification of either 

 of them.
