CATASTieiTA. By J. Rober. 



to such an extent that their generic separation seems fully justified. Although the Catdsfida-species exliibit 

 a fairly uniform facies yet they form various groups, which however are mostly connected by transitions. 

 The genus is distributed from Mexico to South Brazil, jjut has its proper hal)itat in the mountains of tlie 

 west. The species doubtless vary considerably according to the locality, whether they also show seasonal 

 forms has not yet been ascertained. According to Paul Hahxel the cf cf of the (V(/os//f /(/-species have a hal)it 

 of settling in the sunshine on water-washed stones at the banks of rivers, and drinking so greedily that the 

 water comes out again in drops at the anus at short intervals. Not infre([uently Ihey are washed awaj- Ijy 

 the water, which however does not harm them in the least, for immediately afterwards Ihey rise like a water- 

 bird out of the waves, in order to settle anew on the stone where they can reach the refreshing liquid. 



not/ill. C. notha Luc (22a), from Venezuela, is above white with black apical and distal-marginal marking, 



very similar to the following species, beneath with white forewing, the apex of which is reddisii grey, with 

 small yeUow stripes, hindwing ditfusely red-white with yellow stripes in the cellules, distinct triangular yellow 

 marginal spots and red basal spot. 



corcyra. C. COrcyra /•'/'//-. (22a), from Venezuela and Bohvia, is above very similar to the preceding, except 



that on the hindwing the dark markings of the under surface show through. Underside of the forewing white 

 with black apex, (in which yellow stripes are placed, hindwing yellow with black-brown veins edged with 

 standingeri white, black-brown dentate median ])and and vestiges of a marginal lunate macular band. — In staudingeri 

 litlr., from East Peru, the latter is completely developed. In this form the under surface of the hindwing is 

 much lighti'r yellow and the l)lack apical marking of the forewing only reaches to tlie second median vein. 

 The ? has broadened black-brown apical mai'king of the forewing and black-brown spots at the distal margin 

 of the hindwing above. 



pieris. C. picris IIo])ff. (22 a), from Peru, is above white with black apical and subapical marking on tlie 



forewing and also a black marginal line on the hindwing. The under surface is white with brownish and 

 yellow markings on the apex of the forewing. The underside of the hindwing is white, with a lunate line 

 at the distal margin and in the middle, as well as similarly coloured markings at the base, where there is 

 inniiha. also a dark red spot; eacii area of the wing has a yellow longitudinal stripe. — innuba N/'/e. /. /., from 

 Bolivia, has yellow ground-colour above and beneath. 



piirigania. C. curigania Ihir., fi'om Ecuador, is undoubtedly only a local form of straminea Bth: (22a), from 



straminea. Peru; the latter is distinguished by deeper yellow ground-colouring, the presence of three subapical yellow 



spots on the forewing and somewiiat different marking at the distal margin of the hindwing. The under 



surface has the typical ('"/''s^/iy'^-niarking. 



theresa. C. thcresa liUr. (22 a), from Chiritjui, has the outer margin of the forewing concave. Tiie ground- 



colour is dark brown and the yellow markings are narrower than in eiir/i/diiin. The under surface is similar, 

 Init the yellow markings are reduced in favour of the slightly glossy reddish-bluish colouring. 



lu'mbicr. C. nimbicc Bih\ (22 b), from Mexico, has in the cf straw-yellow, in the ? ochre-yellow markings on 



bryson. Ihe upperside. — bryson Htgr. i. I. (22b), from (",liiri([ui and Guatemala, has broadened yellow markings on 

 the upper surtace, tlie under surtace is somewhat lighter, especially at the base. 



siiKijiiini. C. sinapina lU/r., from Peru, resembles i/imhii-a on the upper surface, but the median band is more 



distinctly divided by the veins and the spots of which it is composed are smaller, the submarginal spots 

 of the forewing and the marginal ones of the hindwing are larger, hindwing produced at the anal angle, 

 under surface entirely uniform, ground-colouring mustard-yellow and the veins and markings purple-brown. 

 Only known to me from the description. 



pinava. C. pinava Dhl. (22b), from Bolivia and Peru, is above similar to the preceding species, liut has 



narrower yellow markings and the wings more rounded. The hindwing beneath is suffused with more glossy 

 white, and consetiuently lighter. The ? has above much lis:hter vellow, almost white markings. 



vapina. C. vapina Btlr., from Ecuador, is most closely allied to puiiuK, to which it is very similar on the 



upper surface. All the pale markings are lighter, more sandy yellow, except those at the distal margin, which 

 are white. On the under surface colouring and markings are very similar to iiJiiiJ/icu. bu\ all the light areas 

 are larger and sharper, the ground-colouring of the forewing is light chamois, of the hindwing pearly white, 

 suffused with sulphur-yellow on the proximal half, the white marginal markings are as in iixntco, apex and 

 distal margin of the forewing similarly coloured. Only known to me from the description. 



"'//"• C. colla J>h/. (22b), from Bolivia and Peiai, has above black-brown ground-colour with deep yellow 



macular median band and a submarginal row of small yellow dots on the forewing, broader yellow luodiau 

 band and some yellow marginal spots on the hindwing. The under surface is very gay on account of its
