Tettigoniella inconspicua. (Plate XLIX, fig. 9.) 
Tettigonia inconspicua, Walk., Journ. Linn. Soc. Lond. 
Zool., x, p. 303 (1867). 
By a singular oversight Walker omitted to describe the tegmina 
of this species, which happens superficially to be the most striking 
character. The tegmina from base to commencement of apical cells 
are testaceous, with a large, irregular, transverse, greyish, tomentose 
spot beyond middle, the apical cellular area is dull fuliginous, 
piceous at the inner angle beyond clavus; the whole costal margin 
is very narrowly bluish-black.
