sixth, and seventh joints of its antennae are very much darker than 

 the remaining ones (the basal four and apical four being always 

 pale). 



Whether specifically distinct or not, the A. Chaudoirii is decidedly 

 rare, occurring, however, sparingly at low elevations in Madeira 

 and Porto Santo ; but it has not yet been observed in either the 

 Salvages or the Canarian Group.

Habitat Salvages (ins. majorem, borealem), a Barone " Castello de 

 Paiva" nuper communicatus. 



As will be seen by a reference to the Appendix of this work, the 

 present Apotomus has been communicated recently from the Great 

 Salvage by the Baron Paiva. And, as there stated, it is a most 

 interesting addition to our fauna, from supplying another instance 

 of an Egyptian species (which in this case, however, occurs likewise 

 in the south-east of Europe) inhabiting these Atlantic islands. The 

 example sent by the Baron Paiva I have placed in the collection of 

 the British Museum.

Habitat Canarienses (Fuert.) rarissimus, a ineipso semel lectus. 



Apparently very rare, the only specimen which I have seen 

 having been captured by myself on the summit of La Atalaya (above 

 Betancuria) the loftiest mountain of Fuerteventura. Primo visu 

 it might almost be regarded as the Canarian representative of the 

 Ditomus opacus, of the southern parts of Algeria.
