PAPILIONID^. 



" Thorax stout. 



" Anterior wings triangular, slightly falcate ; the upper discocellular nervule very short ; the 

 lower discoidal nervule curving upwards ; the third subcostal nervule thrown ofl precisely 

 at the end of the cell ; median and subinedian nervules united by a basco-median nervule. 



" Posterior luinys dentate, caudate ; the precostal nervure two-branched, the inner nervule bent 

 downwards, and united to the costal nervure. 



*' Legs moderately robust. Anterior tibiae with a short stout spur, covered by a tuft of hair. 

 Tarsi spiny, the first joint about equal in length to the others combined. Claws simple, 

 curved. 



" Abdomen of moderate length, curved in the male. 



" This beautiful genus, of which one species only is yet known, may be 

 distinguished at a glance from the others of this family by its long porrect 

 palpi. There is little else in its structure to separate it from Ornithoptera 

 or Papilio, though some of its peculiarities indicate an approach to Thais, a 

 genus in which the palpi are more developed than in any other of the 

 Papilionida?, Avith the exception of Teinopalpiis. 



" The posterior wings differ materially in the two sexes ; in the male they 

 are dentate, one-tailed, in the female three-tailed." [Douhleday, I. c.) 



Teinopalpus imperialis.

" Habitat in India Oriental!, Silhet." {Hope, I. c.) 



I received two male specimens of this sj^ccics from Chang-yang, Central 

 China. One of these was captured by Mr. Pratt whilst it was resting on a 

 moss-covered stone in the bed of a small stream where it was allowing the 

 spray from a tiny cascade to fall upon its wings. 



I believe that T. imperialis has hitherto only been met with in Sikkim, and 

 Mr. Elwes gives the following interesting account of its habits in that 

 district : —
