20 Mr. Westwood's Descriptions 



Habitat in Java, D. Horsfield. In Mus. Soc. Mercat. Ind. orient. 



Statura et summa affinitas D. sinuosa : fulva ; abdomine paullo 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 suffuso ; 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, 

 rehquis 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. 



Zeugma. Westw.

 diana tres tantum ramus emittente et cum ilia ramis numerous longitu-
