70 CATASTIGTA. By J. Robee. 



to such an extent that their generic separation seems full}- justitied. Although the Cat<i.-iticta-spec[es exhibit 

 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, but has its proper habitat in the mountains of the 

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

 forms has not yet been ascertained. According to P.\0l Hauxel the cf cf of the frt/as//c'/«-species have a habit 

 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 infrequently they are washed away by 

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

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



In' notlw. C. notha Luc. ('22 a), 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 reddish grey, with 

 small yellow stripes, hindwing diffusely red-wliite with yellow stripes in the cellules, distinct triangular yellow 

 marginal spots and red basal spot. 



]i% corcyra. C. corcyra Fldr. (22 a), from Venezuela and Bolivia, 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 



lljJ standingeri white, blaCk-brown dentate median band and vestiges of a marginal lunate macular band. — In staudingeri 

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

 much lighter yellow and the black apical marking of the forewing only reaches to the second median vein. 

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

 of the hindwing above.

^ pieris. C. pieris Jfopff'. (22 a), from Peru, is above white with black apical and subapical marking on the 



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 

 innuba. also a dark red spot; each area of the wing has a yellow longitudinal stripe. — innuba Stgy. i. 1., from 

 Bolivia, has yellow ground-colour above and beneath. 



1' eurigania. C. curigania lliiw., from Ecuador, is undoubtedly only a local form of straminea Btlr. (22a), from 



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

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



surface has the typical Catudlcta-VAi^vVmg. 



P5„ C. theresa Bth-. (22a), from Chiriqui, has the outer margin of the forewing concave. The ground- 



colour is dark brown and the yellow markings are narrower than in eiiri'ianiu. Tiie under surface is similar, 

 but the yellow markings are reduced in favour of the slightlj^ glossy reddish-bluish colouring. 



' nimbice. C. nimbice Bdv. (22 b), from Mexico, has in the cf straw-yellow, in the ? ochre-yellow markings on 



biyson. ^lie upperside. — bryson Stj^K^-if I. (22b), from Chiriqui and Guatemala, has broadened yellow markings on 

 the upper surface, the under '^n%ce is somewhat lighter, especialh' at the base. 



i4l 



sinapina. C. sinapina lltlr., from Peru, resembles nimbica 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 iiindwing are larger, hindwing produced at the anal angle, 

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

 Only known to me from the description. 



Jo*' pinava. C. pinava Dbl. (22 b), from Bolivia and Peru, is above similar to the preceding species, but has 



narrower yellow markings and the wings more I'ounded. The hindwing beneath is suffused with more glossy 

 white, and consequently lighter. The ? has above much lighter yellow, almost white markings. 



Ji5 vapina. C. vapina Btlr., from Ecuador, is most closely alhed to putai:a, 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 philAlien, but 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-5'ellow on the proximal half, the white marginal markings are as in iiunico, apex and 

 distal margin of the forewing similarly coloured. Onlj^ known to me from tiie description. 



(X'ji co.'/a. C. colla DU. (22 b), from Bolivia and Peru, 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 median 

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