PLATE CXL. 



lieu of the already appropriated species Papilio Tynderseus, to which 

 his name was before annexed, we shall be amply gratified in the 

 opportunity the circumstance has afforded us of testifying our good- 

 will towards that distinguished entomologist, and under the persuasion 

 that it may prove acceptable, we shall venture to give publicity to 

 this very fine and non-descript species under the appellation of 

 Papilio Latreillii. 



With respect to the history of this very interesting novelty, we 

 are only enabled to state that it is a native of Nepaul in India, from 

 whence it was received by Mr. MacLeay, and that it is to his friend- 

 ship we are indebted for permission to make the species known. 



The accuracy of the figures, it is presumed, must render any 

 very minute description of this curious insect needless, and this the 

 more especially since both the upper and the lower surface is repre- 

 sented in the annexed plate. A few observations may, how^ever, 

 perhaps be allowable, in order to point out those particulars in 

 wliich it bears the nearest approximation in appearance to the species 

 already known. 



At the first view, it seems to bear a remote affinity to Papilio 

 Hector, yet it will require no comparison to assure us of its decided 

 specific difference ; the elongation of the posterior wings, which more 

 resemble those of Papilio Coon and some few other Papiliones, afford 

 in particular a striking dissimilarity ; neither is the singularly 

 expanded trilobate space of Avhite, in the disk of the posterior ones, a 

 less conspicuous distinction of our new species Papilio LatreiUii. The 

 nearest approach in this respect to the insect before us is to be
