about one fourtli of the length of the antennaj, graduallj' formed, very slightly curved outwardly at the tin ; 

 the inside liaving a scarcely defined longitudinal keel. 

 Thorax woollj', especially behind ; tippets long and narrow. 



Fore Wings large. Anterior margin rather strongly arched ; apical angle rounded. Apical margin about t-ivo 

 thirds of the length of the anterior, entire, slightly emarginate in the middle. Inner margin two thirds of the 

 length of the anterior. Postcostal vein with the first and second branches arising before the extremity of the 

 discoidal cell ; third branch arising close beyond its extremity ; fourth branch arising at three fourths of the 

 length of the wing. Upper disco-cellular vein almost obsolete, arising nearly at one third of the length of the 

 wing from the base ; middle disco-cellular short, transverse, slightly directed toM^ards the base of the wing ; 

 lower disco-cellular obsolete, so that the discoidal cell (the anterior extremity of which scarcely extends beyond 

 the first branch of the median vein) is open; third branch of the median vein regularly arched. 

 Hind Wings forming a broad oval. Outer margin scalloped. Precostal vein moderately strong, curved outwards. 



Branches of the postcostal vein arising at a short distance from its base. Discoidal cell open. 

 Fore Legs in the male very small, thin, and with the tibia; and tarsi but slightly clothed with elongate hairs. 

 Tarsus about two thirds of the length of the tibia. Fore Legs of the female consideraljly longer than tliose of 

 the male, scaly. Tarsus about two thirds of the length of the tibia, obliquely truncate at the tip, which is 

 furnished with several pairs of fine spines. 

 Four Hind Legs formed as in the last genus. 

 Abdomen ratiier small ; robust in the female.

The above characters are taken from Papilio Thyelia of Fabricius, an Indian insect which appears, at first sight, to have some 

 relationship with the fritillary butterflies; its real affinities are, however, evidently to be met with in the species of Adolias and the 

 neighbouring genera. Hiibner, in his Zufrar/c, lias given a figure of an insect whicli lie names Syniphaidra Alcandra, witli Georgia, 

 Florida, as its liabitat ; but it is unquestionably identical with Thyelia, and incorrect in the locality given to it, its true station being 

 Central India, whence Brigadier Hearsey brought a very fine series, some of which arc two tliirds of an inch wider than our figure. 

 The under surface of tlie wings is more elegantly varied than the upper ; the discoidal cell in all the wings being marked with several 

 pink spots of various forms edged with black, and the hind wings having a whitish bar running obliquely across the middle. 



I have followed Iliibner in also referring to this genus the Papilio iEropus of Linnaius, which seems most nearly allied to it, 

 differing only in having the lower disco-cellular vein present in the fore wings, tlius shutting the discoidal cell transversely at about 

 two fifths of the length of the wing from tlie base. The first branch of the postcostal vein is also united with the costal one for a short 

 distance, but is emitted again near its apex. The only s[iecimen of this species whicli I have been able to examine is in the British 

 Museum collection, in a very dilapidated state, wanting the head. It is of a dark brown colour on the upper side, with a liroad 

 orange bar running across all the wings just beyond the middle, parallel with the outer margin (paler-coloured in the females), the 

 anterior portion being broken into several distinct spots towards the costa of the fore wing. It is paler-coloured beneath, with several 

 black and white characters towards the base of the wings.
