Mr. W. L. Distant on Ilomoptera. 279 



we cannot refer to the opercula, and I have never seen a male 

 specimen. Stal, in describing- his P. fatiloqun, certainly 

 writes " operrulis nuUis," but this cannot be accepted as the 

 type of Prasia^ and the true female type has all the appear- 

 ance of what Breddin refers to as typical Drejyanopsaltria . 

 (2) To add to the confusion, Breddin gives as the type of 

 JJrepanopsaJtria, Lemheja cidta^'T>h\., a species I have never 

 described ; but it is probable he was referring to my Prasui 

 culta (Ann. & Mag. Nat, Hist. (7) i. p. 97, 1898). 



Genus Lembeja. 



Lemheja, Dist. Mon. Orient. Cicad. pp. 103 & 147 (1892), n. nom, 

 Ferissoneura, Dist. Proc. Zool. Soc. Lond. 1883, p. 189, nom. praeocc. 



Type, L. maculosa, Dist. [Perissoneura]. 



In reference to this genus, Herr Breddin (Hem. Celebes, 

 p. 113, 1902) has formulated the dogma " Genus Lemhejam 

 Dist. a Prasia Stal naturaliter distingui non posse 

 existimo.^^ But this is more of a criticism on the veteran 

 entomologist Dr. Karsch, of his own Berlin Museum, who has 

 described two species in that genus.
