phlwus, its greatly enlarged, oval head, and elongated, subcordate- 

 cylindrical prothorax, in conjunction with its much developed man- 

 dibles and rather clavated antennae, giving it a character essentially

 the simplicicollis.

Trogophloms simplicicollis, Wall., Cat. Mad. Col. 203 (1857). 

 Habitat Maderenses (P to S to ), in inferioribus sat copiose deprehensus. 



Captured by myself (rather abundantly) in Porto Santo, of the 

 Madeiran Group in company with the T. nigrita, at the Zimbral 

 d'Areia. It is a minute and narrow species, remarkable for its (some-

 from even the rudiments of fovese, and for being also, together with 

 the head, most closely, delicately, and evenly punctulated.

A single example of this common European insect was taken at
