Mr. E. Doubleday on some new Diurnal Lepidoptet'a. 233 



tlie radial nervure two vittae united at the base, the upper one 

 followed by a round spot ; above these between the nervules five 

 vittse, of which the one nearest the costa is pointed, the others 

 bifid externally, each vitta followed by three spots, of which the 

 lower are somewhat lunulate, the upper ones more rounded ; four 

 rounded spots near the apex, two near the anal angle. The inner 

 margin is glaucous, the apex tinged with brown. Posterior wings 

 castaneous, darker in the females than in the males, with seven 

 whitish subdiaphanous vittae placed between the nervules, all, ex- 

 cept the innermost, followed by a round white dot, beyond which 

 the ground-colour of the wings is slightly darker; towards the 

 outer margin a scries of indistinct whitish spots, sometimes nearly 

 obsolete. Cilia of all the wings spotted with white. Below, the 

 anterior wings are black with strong blue reflections, the apex 

 broadly chestnut, slightly bronzed towards the disc ; the markings 

 as above but clearer, with two additional spots on the costa near 

 the base. Posterior wings paler than above, the white portions 

 more or less irrorated with chestnut scales ; on the margin a di- 

 stinct series of whitish lunules. 



Head, thorax and abdomen black, clothed with gray hairs ; 

 head above and thorax below spotted with white ; abdomen below 

 gray ; palpi black, spotted with white ; antennae black. 



In the cabinets of the British Museum, &c. 



This species, which much resembles Pap. Agestor and Danais 

 Tytia, has the cells of all the wings open. The genus Diadema 

 as it now stands requires subdivision ; the neuration I believe will 

 be of great service for this purpose.

Anterior wings fuscous with whitish markings, viz. an elon- 

 gate spot at the base and extremity of the discoidal cell, an oval 

 one near the costa towards the middle, a scries of vitta? between 

 the nervules, of which the first and third from the costa are short 

 and narrow, the second also slender but longer, the fourth long, 

 the fifth and sixth progressively shorter, well-defined towards the 

 base, less so externally, the seventh broad, short, the eighth broad, 

 longer than the seventh, the ninth long, commencing near the 

 base, the tenth occupying the inner margin from the base nearly 

 to the anal angle ; near the margin between the nervules a series of 

 seven more or less rounded spots, of which the one nearest the anal 

 angle is geminate ; this series, preceded by another of six spots, 

 of which all except the first are connected with the vittae by in- 

 distinct prolongations. Posterior wings with the base and abdo- 

 minal margin whitish, the nervures broadly brown, a broad vitta
