CICADELLINAE: PART 2. NEW WORLD CICADELLINI 829 
My interpretation of Neokolla aridella DeLong rests mainly on specimens 
identified with the aid of the revision of DeLong and Currie (1959a). The 
male holotype of Neokolla remina DeLong and Currie appears to be conspecific 
with their N. aridella DeLong, and the descriptions of the male genitalia (p. 
65) do not reveal the distinct male genital structures they specified in the 
diagnosis of remina. N. aridella is a variably marked species, and the DeLong 
collection has a long series marked differently from typical aridella and from 
the variety described as remina. 
My interpretation of Tettigonia gothica Signoret is based chiefly on the 
original illustration, a species which cannot be the same as 7. hieroglyphica Say 
in the sense of Ball’s 1901b (pl. III, fig. 1) interpretation of the latter. Ball’s
