PAPILIONID^. 



ill only four iiervules ; of which one is thrown off beyond the middle of the cell, the 

 second a little before its end, the third about halfway between the cell and the apex of the 

 wing. Upper discocellular and baseo-median nervules both wanting. 

 "■ Posterior wings elongate, ovate, emarginate internally, witliout any abdominal fold^, subdia- 

 phanous, Precostal nervure not bi'auched. 

 " Legs short. Anterior tibifc with a short flat spur. Tarsi longer than the tibite ; basal joints 

 about equal to the rest combined; second, third, and fourth progressively shorter; fifth 

 longer than the second. Claws simple ; inner very sharp, long, grooved internally ; outer 

 about two thirds the length of the inner ; the points directed inward ; base of the claws 

 with a horny projection. 



" Abdomen short, stout, very hairy, terminated in the females by a corneous pouch or plate. 

 " Larva cylindric, slightly tuberculate. 

 Pupa cylindrico-conic, subfoUiculate. 



" This genus may be known from all other Papilionidae by the structure of 

 the anterior wings, in which one subcostal nervule, apparently the first, is 

 wanting. This character and its more distinctly triarticulate palpi separate 

 it from Doritis on the one hand, and Eurycus on the other. 



" There is a striking resemblance in the markings of the anterior Avings in 

 this genus and in Euri/cus, more especially in the round black spots in the 

 middle of, and at the end of, the cell. In fact Eurycus may be viewed as 

 the Australian representative of Parnassius. 



" The larvae, as far as is known, feed on sedums, saxifrages, and fumi- 

 tories ; they are pubescent, velvety black, with numerous orange spots and 

 small tubercles. 



" The pupffi are enclosed in a loose silken web, supported also by some 

 transverse threads : they are subcylindric, conic posteriorly, not angular, and, 

 from being covered with bluish powder, very much resemble those of the 

 genus Catocala amongst moths." [Douhhday, I. c.)
