198 NEMATUS ALBIPENNIS. 



from Zaddach under the name of dilutus. As Ste- 

 phens' name is in any case the earliest, no change is 

 required in the nomenclature beyond the excision of 

 the name jjallescens as synonym. 



Nbmatus glottiands (Vol. II, p. 148). 



Konow accepts my suggestion (1. c, p. 149) that this 

 is identical with N. ferrugineus, Foer. 



Nbmatus antennatus (Vol. II, p. 155). 



Konow is no doubt correct in sinking this as a 

 synonym of aurantiacus, Htg., non Cam., Thorns., 

 Vollenhoven. 



Nematus aurantiacus (Vol. II, p. 173). 



This is not, as stated, aurantiacus, Htg. What 

 it may be I am unable to say. 



Nematus albipennis (Vol. II, p. 175). 



Konow treats N. confusus as a distinct species from 

 albipennis. 



If Konow' s views of the limits of the genera are to 

 be accepted, our species will be arranged as follows : 



Peistiphoua. 



Conjugata (Vol. II, p. 140). 

 Betulse (Vol. II, p. 138). 

 Quercus (Vol. II, p. 52). 

 Pallidiventris (Vol. II, p. 108). 

 Oblonga (Vol. II, p. 69). 

 Abbreviata (Vol. II, p. 60).
