PIERIS BECKERIT, n. sp. 4—7. 



Primaries produced apically, sliglitly excavated on costal and liind margins. 



Male. Exj^ands 2 inches. 



Upper side pure white, the texture of secondaries slighter than that of pri- 

 maries, discovering the sj^ots of under surface; hase of wings not powdered with 

 black as in allied species ; primaries have the ajjical half of hind margin bordered 

 by small black patches or clusters of scales, diminishing in size to middle of mar- 

 gin; anterior to these two similar sub-apical j^atches and a third in upper median 

 intersj)ace; on the arc a dense black subrectangular sj^ot (not reaching the costa) 

 with a central white streak. Secondaries immaculate. Fringes white except against 

 the aj^ical spots, there black. 



Under side white; the nervules at apex and on upper hind margin bordered 

 by black scales and suffused with greenish yellow; the sjiot on intei'space black 

 and as on upper side; cellular spot enlarged, its base broadened and posterior edge 

 excavated. 



Secondaries have all the nervures and their branches yellow; those termina- 

 ting on hind margin edged by broad bands of yellow green reaching to middle of 

 disk and connected anteriorly; three large spots of same color about the cell, two 

 being at the outer angles, and one above and reaching the costa; another large 

 triangular subapical spot on costa ; the nervures at base also banded with green ; all 

 .these bands and spots slightly sprinkled with black scales. 



Body above covered with grey hairs; beneath, abdomen yellowish, thorax 

 white; legs white; palpi white, grey on ujijier side and at tip; antennae white

 white scales ; tip pale fulvous.

Primaries less produced and broader than in male; same shade of color; the 

 marginal S2:)ots enlarged and extended to second branch of median ; in addition to 

 the three submarginal spots, which are also enlarged, is another in submedian in- 

 terspace and a streak below this along inner margin; the cellular spot much en- 

 larged, rhomboidal, with slight central streak; secondaries have a patch on costa 

 and four on the marginal nervules commencing at and posterior to subcostal ; also 

 an interrupted submarginal stripe opj^osite cell, jjosteriorly indistinct; under side
