338 Mr. A. G. Butler on Madagascar Lcpidoptera. 



Unfortunately only one example of this singular Terlas 

 has been received. 



21. Catopsilia deciptens, sp. n. 



<£. Above white, tinted with sulphur-yellow, which be- 

 comes more intense towards the middle of the wing ; prima- 

 ries with the costal border and basal third bright gamboge- 

 yellow, outer edge of the basal area trisinuate and oblique : 

 secondaries with the basal half, excepting on abdominal 

 border, bright gamboge-yellow ; the usual pinky-white sub- 

 costal elongated mgaly patch : head pale greyish flesh-colour ; 

 collar of the same colour in front, but greenish behind ; thorax 

 and base of abdomen greenish sulphur, remainder of abdomen 

 white ; antennas above grey, with orange-tipped blackish club, 

 below pale buff. Primaries below with the lower half of the 

 cell and interno-median area bright sulphur-yellow, diffused 

 externally ; the usual thick sulphur-yellow scent-fan on 

 internal border ; disk white ; costal, apical, and external areas 

 cream-coloured : secondaries and pectus cream-coloured, venter 

 white. Expanse of wings 2 inches 8-11 lines. 



? . Wings above white : primaries with the basal two fifths 

 bright sulphur-yellow ; a large black spot at the end of the 

 cell ; costal border testaceous at base, otherwise dark brown ; 

 apical and external borders rather narrowly dark brown, the 

 latter broken up into spots towards the external angle ; an 

 angulated series of four widely separated but nearly equi- 

 distant dark brown spots across the disk : secondaries with 

 the lower part of the cell and interno-median area tinted with 

 sulphur-yellow ; an indistinct irregular cliscal series of spots, 

 and a still less distinct marginal series brown : head and collar 

 pale purplish brown ; tegulas the same colour at the base, but 

 tipped and fringed with whitish ; thorax blackish, clothed with 

 greenish-white hairs ; abdomen white. Primaries below with 

 an orange streak at the base of the cell, and a greyish annulus 

 on the discocellulars, otherwise as in the male ; secondaries 

 and body as in the male. Expanse of wings 2 inches 

 8 lines. 



Of this interesting species Mr. Cowan sent two males and 

 one female ; it takes the place of C. crocale in Madagascar, 

 just as C. thauruma does that of C. catilla. 



22. Belenois coniata. 



Belenois coniata, Butler, Cist. Ent. ii. p. 391 (1879). 



The present example measures only 2 inches 1 line in ex- 

 panse of wing. The species seems not to be uncommon.
