Inhabits Madeira proper, oecurring in the moist sylvan di- 

 stricts of intermediate altitudes ; detected by myself at the base 

 of the lofty perpendicular rocks near the upper extremity of the 

 Ribeira de S** Luzia_, during July 1855. It is a truly indigenous 

 Forficula, and of a very remarkable type, — its apterous body, much 

 abbreviated (apically-emarginate) elytra, and sub-opake, greatly 

 flattened surface, in conjunction with the total freedom of even 

 its male forceps from internal teeth, giving it a character which 

 it is impossible to mistake. 



Fam. BLATTIDiE. 



Genus Blatta, Linn. 



Blatta Ericetorum. 



B. nitida, nigra, limbo late elytrorumque sutura anguste pallidis, 

 subdiaphanis ; capita vel omnino vel solum hinc inde pallido ; 

 prothoracis dorse nunc vix nunc distinctius dilutiore, iuterdum 

 etiam prothorace toto pallido ; elytris modo abdominis longitudine, 

 modo paulo longioribus ; alis minutis, fere obsoletis ; antennis 

 palpisque ad basin palhdis, apicem versus obscurioribus ; pedibus 

 vel omnitto pallidis, vel ad apicem ipsum tarsorum tibiarumque 

 (valde spinosarum) nigrescentibus. — Long. corp. 4^-5^ lin. 



Inhabits Madeira proper, occurring principally beneath the 

 loose outer fibre of the gigantic Heath-trees, on the upper limits 

 of the sylvan districts, — from about 4500 to 5000 feet above the 

 sea. It has been examined by Dr. Fischer of Friburg, who 

 regards it as new, though allied to the B. marginata of Southern 

 Europe.
