very moderate spécifie differentiation. In his description of another 

 proposed genns, Aufilerna (1). he writes « posterior margin emar- 

 ginate, while it is truncate in Aufidus ». This is inaccurate; in the 

 type of Aufidus (A. trifasciatusj the posterior pronotal margin is 

 distinctly emarginate ; neither did Stâl make that structural cha- 

 ractera generic distinction, lie simply writes((Tliorax sexangularis». 

 On the other hand Aupterna Kirk. is apparently only to be separated 

 trom Aufidus by the venation of the tegliiina — « 3 discoidals 

 (subapical), 4 apicals well marked, while there areanother 5 small 

 cells marked ofîon the costal cell ». 



In the typical species ali thèse characters are mère or less repre- 

 sented, and the divisions of the costal cell are inconstant even in the 

 same species and even in the same spécimen.

KmKALDY (Rep. Exp. StalHaw. Plant Assoc, Bull. III, p. 25 (1907)) 

 writes « Distant bas overlooked the fact that Petalocephala is a syno- 

 nym of Camptelasniiis ». 



Camptelasmus Spin. {Mem. Mat. Fis. Soc. Ital. Sci. Modena, XXV, 

 Part I, p. 96 and 150), is described particularly as having « ocelli 

 nulli ». Stâl [Hem. Afr., IV, p. 103(1866) in redescribing his genus 

 writes « ocelli versus basin verticis positi, ab oculis quam iuter se 

 longius remoti «. He certainly also writes « Genus Camptelasmus 

 Spin . Petalocephalœ affine viditur », but in 1870 {Ofv. Vel. Ak. Forh., 

 p. 732) he uses his genus Petalocephala as he had every reason to 

 do. I therefore cannot see what a fact », has been overlooked.
