The specimen of " streckeri," of which Leech, Trans. Ent. Soc. Loml. p. 290 

 (1898), referred to as being darker than sieversi, and which apparently convinced 

 him of the sj)ecific identity of streckeri and sieversi, was not streckeri at all, but 

 the new lli/loicus described on j). 144 of this paper.
