 broadly greyishly tomentose. 



Tegmiua and wings pale hyaline ; tegmina with the costal membrane pale castaneous. 



Opercula small and lobately directed inwardly ; the rostrum reaches the posterior coxae.

This species is very variable in coloration, some specimens liaving the abdomen olivaceous 

 in hue, and in others the distinctive markings of the pronotum are not well pronounced. 



Stal (Hem. Afr. iv. p. 27) recites T. macuUcoUis as a synonym of Tibicen hnuincus, Fabr., a 

 species found in the island of Mauritius. This is incorrect, and the two species belong to 

 different subgenera as deiined by Stal himself; T. hranneus belonging to the s.g. Ahricta, and 

 T. maculicollis to the s.g. Abroma.
