In Mr. Smith's descriptions of Japanese TentJiredinidcd, published 

 in Trans. Ent. See. for 1874, the following errors occur : Dolerus 

 nigro-coeruleus and Dol. fuscipennis (I. c. p. 384) belong to the genus 

 Emphytus ; D.fuscipennis is, I believe, only the ^ of nigro-coerideus. 

 Macropliya vexator (p. 378) and M. luctifera (p. 380) likewise belong 

 to Emphytus. Selandria nigriceps (p. 376) is a Monophadnus. 



Derecyrta deceptus, Smith (Trans. Ent. Soc, 1876, p. 474, pi. 4, 

 fig. 6), if correctly figured, is not a Derecyrta, but probably a Xiphy- 

 dria, for it is figured as having two marginal cellules, while Derecyrta 

 has only one {cf. Smith, Ann. and Mag. Nat. Hist., 1860, p. 355). 



Hartig (Blattw., 369, pi. viii, fig. 9) it may be added has described 

 and figured Xipliydria as having only one marginal cellule, whereas it 

 has two.
