wings, 2-4 on the hind; postcubitals, front wings 9-10, mostly 9 in both sexes (47-7 °/,), hind wings 7-9, 
mostly 8 in both sexes (74:9°/,); pterostigma rhomboidal, brown, surmounting slightly less than a

The material before me was probably collected by Mr. S, F. Aaron in the vicinity 
of Corpus Christi in 1884 (see Papilio, iv. p. 159). The species is surely a member of 
the tropical Gulf fauna, and is to be looked for farther south. |
