a siibmai'<;inal row of throe yellowish white spots, one near the costal margin, 

 the third, largest, near the anal angle, and the second, smallest, midway between 

 them ; apical margin with faint linear yellowish marks in the cellules ; radial 

 nervnles black ; base of both wings somewhat blackish. 



Hindwiugs yellowish white ; apical lialf black, witli a transverse row of 

 yellowish wliite spots gradnally decreasing towards the anal angle. 



Underside: forewings in pattern like the npperside ; bnt the basal two-thirds 

 almost ochre yellow, the apical angle vinaceous rnfons, the marginal yellow spots 

 larger, and the snbmarginal row of markings consisting of a doubled spot at 

 the costal margin, a small spot each in tlie discal cellnles, and a larger spot, 

 near the anal angle. 



On the hindwings. the basal half lemon yellow, with a faint transverse 

 brownish line ; apical half light vinaceous rnfons, marked as the npperside, but 

 the spots larger.

Allied to T. amina (Rew.) (Exot. Butterfl., iii., Pieridae, PL VIII., tigs. 1, 2, 3) ; 

 but the black colour on the uppermle is much larger in extent, and is bisin\iate 

 on the disc of the forewings ; T. amina has only a marginal row of yellowish 

 spots on the hindwings, while in my new species there is an additional subdiscal 

 row of spots. On the underside Hewitson's species has a red discal patch on 

 the forewings which is absent from T. bipartitiis : the black and vinaceous ruf'ons 

 colour of the apical third is much more extended in the new form, and the 

 yellowish spots are reduced in size ; the hindwings which are marked with a 

 snbmarginal brownish band and a discal, interrupted, brownish line in' T. amina 

 (Hew.), have the apical half vinaceous rufous in my species, with a subdiscal 

 and marginal row of yellowish marks. 



6. Teracolus chromiferus sj). nov. 



S. Uppersidc : both wings white, nervnles of tlie forewings feebly blackish, 

 veins of the hindwings white. Forewings with a black spot at the end of the cell : 

 apex of the wing lake red, this red patch bordered with black at the costal and 

 marginal sides, not so towards the disc. 



Underside : forewings white, apex chrome yellow, a black spot at the end of the 

 cell, as on the npperside. 



Hindwings chrome yellow, witli a small black spot at the apex of the cell, a 

 discal row of very faint black point-like marks, two of them more obvious, one at 

 the costal margin, the other towards the anal angle ; base of the costal margin 

 narrowly bordered with orange chrome.

Comes nearest to T. buxloni Butl. The red juitch of the apex of the forewings 

 is smaller in extent ; the veins of the forewings are white for the most part, those of 

 the hindwings entirely white, while in T. huxtoni, as well as in T. anax, the veins 

 are black ; on the under surface the forewings are yellow at the apex, and the hind- 

 wings, which have a very faint tint of yellow and scarcely a trace of black markings 

 in T. buxtoni, are entirely yellow in the new species, and their disc is almost marked 

 as in T. anax.
