56 MR. A. G. BUTLER ON THE GENUS DANAIS. [Jan. 23, 



50. Danais cenone (D. vitrina, Felder?). 



Male. Upperside — wings hyaline, the same form as in D. cleona, 

 d ; nervures, end of front-wing cell, and margins black ; hind mar- 

 gins broadly black. Front wings, basal area divided by the nervures 

 into four parts ; subapical patch in three parts ; three costal and 

 seven submarginal spots. Hind wings with a large basal area, di- 

 vided by the nervures into twelve unequal parts ; a double series of 

 submarginal brown spots, two or three of which are pupillated with 

 white at the apex and anal angle. Body — thorax black, with creamy 

 spots ; abdomen white, with a dorsal black line. 



Underside — front wings with a submarginal row of fourteen minute 

 white spots in couples along the hind margin ; otherwise as above. 

 Hind wings with a double submarginal row of white, not brown, 

 spots ; otherwise as above. Body — thorax black, with numerous 

 creamy spots ; abdomen white. 



Expanse of wings 2-j-g- inches.

Note. — It has been suggested to me that I was wrong in describing 

 this species, on the score of its being "nothing more than I), albata ; " 

 but when the two insects are placed side by side, I think that few 

 entomologists would deny that they are very distinct. The hind- 

 wing cell in D. albata is much broader, the fore wing more convex 

 in front, the wings not so transparent, the marginal and subapical 

 spots much larger and more numerous, the hind-wing disk almost 

 entirely suffused with brown, the submarginal spots all white : 

 considering these points of distinction, as well as the difference of 

 locality, I think I should be scarcely justified in sinking my species 

 into a synonym of D. albata. It may, however, be identical with 

 1). vitrina of Felder ; but it is almost impossible to recognize such 

 closely allied species without figures.

52. Danais gloriola, sp. n. (PI. IV. figs. 3, 4.) 



Male. Upperside — wings the same form as in D. cleona, d , 

 bright transparent yellow, increasing in intensity towards the base ; 

 nervures black. Front wings, anterior margin, base, upper half of 

 cell, apex, hind margin, inner margin from the anal angle to the 

 middle of the third median branch, and an irregular oblique band 

 from the end of the cell to near the middle of the hind margin 

 black brown ; a very indistinct series of minute submarginal white 

 dots. Hind wings, base brown ; basal area divided into ten unequal 

 parts ; outer margin broadly brown. Body, head, and prothorax 

 black, spotted with white ; the rest of the body brown. 



Underside — front wings, submarginal series of spots more distinct;
