Postscript, added 15th July, 1910. — After this paper was read, 

 we came upon a reference in Kellogg(1896, p. 164) which gives the 

 generic characters of Piagetia, P. rayazzii Picagha, being the type. 

 This parasite is certainly congeneric with Menojion titan Piaget, 

 and Tetrophthalmus chilensis Grosse(Zeit. f. wiss. Zool., xlii., 1885, 

 p. 534). As Grosse's genus Tetrophthalmus antedates PicagHa's 

 Piagetia, which name is, moreover, already preoccupied, as 

 Neumann has pointed out, Grosse's genus must stand (with T. 

 chilensis as type), and Piagetia Picaglia, as well as Piagetiella 

 Neumann, must rank as synonyms. We refrain at pi-esent from 

 commenting upon the individuality of T. chilensis, and the 

 various other species and subspecies of the titan-grou^ {T. titan, 

 Piag., T. ragazzii Pic, 7'. consanguineus Piag., T. linearis Kell., 

 and 7\ impar Kell.). 



According to the ruHng of tlie International Commission, 

 Grosse's genus Tetrophthalmns is not invalidated by Tetrophthalma 

 Less., 1833(Coleoptera), and Tetraophthalmus de Haan, 1834 

 (Coleoptera).
