[Osten-Sacken, C. R.] On Professor Brauer’s paper: Yersuch einer Cha- 
racteristik derGattungen der Notocantheu, 1882. L. c. pp. 363-380. 
An elaborate criticism, containing inter alia the following notes : — 
Loew’s Xylophagidce is a heterogeneous group, in which Xylophagus and 
Ccenomyia may be retained ; they are allied to the Leptidaj, to which 
latter family Arthropeas and Glutops must be referred ; and Subula may 
be referred to the Beridina ; Xylophagus , Latr., however = Subula , and 
JPachystomus , Latr., = Xylophagus , auct. Biastes , Walk, (preocc.), = 
Rosapha , Big. ; Toxoccra limbinervis, Macq., = Eudmeta marginata (F.), 
Wied. ; Solva, Walk., = Subula, Macq.; Dip)hysa, Macq., is a fictitious 
genus, founded on au error regarding the venation of Xylophagus spini- 
ger (= Boris servillii , Macq.), and rujipalpis , Wied. ; Engonia, Thyla- 
cosoma , and Lagenosloma, Brauer, = Negritomyia, Big., and Ruba and 
Massicyta, Walk., respectively ; Drasteria and Compsosoma , Brauer, are 
preoccupied (Hfibn., Lcp ., & Serv., Col.); Engonia aurata , Br., = Clitel - 
lariafestinans, Walk. ; Ephippium spinigerum, Dol., = bilincalum, F. ( bivit - 
talum, Wied.) ; but E. maculipennis, Macq., is distinct ; Antissa, Walk., 
and Cyanauges, Phil., are probably distinct ; the true type of Cacosis , 
Walk., is Sargus niger t Wied.
