Statura et summa aflBnitasZ). sinuosm: fulva; abdomine pauUo obscuriori, linea tenui longi- 

 tudinali dorsali flava, genitalibus rufescentibus. Organa haec externe partes sequentes 

 exhibent, scil. laminam corneam dorsalem lateribus deflexis apice acute bifidam, appen- 

 dicibus duabus lateralibus multo minoribus conicis lobisque duobus magnis apice ro- 

 tundatis inermibus concavis inferis. Mesothoracis dorsum tricarinatum ; alae pallide 

 hyalinae, margine antico late obscure rufescenti-fusco, ad venam postcostalem extenso, 

 basin versus pallidiori et magis sufiuso ; ramis quatuor posticis venae postcostalis ad ba- 

 sin nigricantibus, inde margo obscurus interne sinuosus apparet ; venis ramisque lon- 

 gitudinalibus quam in T. sinuosd magis regularibus; venis in margine obscuro rufis, 

 reliquis flavidis, ad apicem obscurioribus ; venis brevibus transversis obscuris. Pedes 

 et rostrum pallide flavidi ; tibiis posticis calcare ante apicem alteroque apicali brevi ar- 

 matis. 



Notwithstanding the diversity of the geographical range of this species, and 

 the much greater regularity of the veining of its wings, I cannot even sub- 

 generically separate it from the West African species described by Boheman, 

 as it agrees with the latter in all its essential characters ; and even the same 

 general arrangement of the veins of the wings will be found to exist both in 

 it and T. sinuosa.
