1024 Additions: PIERIDAE. By J. Rober. 



Megamstoma bernardino Edw. (p. 94), according to Wriciht's figure, is a form of eurydice (26 f ) with 

 amoi-phac. blacli distal margins of the hindwings. The $ does not differ from that of eurydice. — amorphae ll';-. is a form 

 of eurydice-'^ marked blackish. 



cilriim. M. helena ab. citrina Jorg. does not exhibit the orange colouring of the hindwing, but it is lemon- 



coloured; it is conunon in tJie Province ef Tucuman from May till August. 



coUaidcti. Nathalis plcmta $ ab. coliaides Fassl is the (J-like 9 form; not rarely there occur transitions to 



the usual form. Bogota, Colombian Eastern Cordilleras, 2600 to 3200 m. The insects are fond of drinking 

 on a common, yellow blossom of Hieracium especially in sunny districts. 

 dcscrti. Anthocharis deserti Wr. from the western coast of North America is a small form of cethura (28 b) with 



scanty markings and colours. 

 Ilura. A. flora 11/'. from the same region is a robust and more profusely marked form of reakirtii (28 a); 



inoUifi. the $ is above and beneath pale yellow ; in mollis Wr. the subapical marking of the forewing above is reduced. 

 callenie. Western coast of North America. — caliente Wr. which the author takes to be a separate species is presumably 

 only a small and pale form of pima (28 a). Western coast of North America. 



Of Pliulia u.ymphula Btlr. (28 c) Giacomelli has discovered a new form in Argentina (in the Andes 

 rccdi. of Mendoza) and denominated it reedi. At present I do not know any further particulars. 



aconquijae. Ph. aconquijae Jorg. (192 d) is common beginning from the middle of March in the Aconquija Moun- 



tains at altitudes of 3500 to 3750 m and flies together with Colias hlameyi and species of Tatochila. It is above 

 and beneath very much like nymphula (28 e), but the under surface is of a darker ground-colour and with a 

 more intense and profuse marking. As there is no comparative material of nymphula from Chile available, 

 it is still uncertain in what way the latter differs from the form figured on t. 28 c, which was considered by 

 0. Staudinger to be identical with the Chilian form and from aconquijae; aconquijae may be synonymous 

 with nymphula, in which case the Bolivian form would have to be newly denominated ; it maj^ then be called 



joergcHseiii. joergenseiii in honoiu' of the author of ,,Las Mariposas Ai'gentinas" (Buenos Ayres 1916), who has made himself 

 very meritorious by the exploration of the Ai'gentine Pierids. 



JiinhaVts. Pseudopicfis limbalis sp. nov. (192 d) was discovered by Mi-. A. H. Fassl, who had the kindness 



to send us the figured specimen; in January near Altamira on the Rio Hingu. The under surface is uni-coloured 

 white except the yellow basal spot. If penia (28 e) would have to be considered as a separate species, this would 

 also have to be done with limbalis. 



c'drineUa. Of Disitl. citrinella Fldr. (192 d) we are now able to reproduce figures of the (5*; the $ is stUl unknown 



to lis. According to Felder, this species occiu-s in Venezuela (Prov. of Merida) and in the Cordilleras of Bogota 

 (Colombia); before me are specimens from Western Colombia (Rio Magdalena) and Bolivia. D. citrinella is 

 presumably a species scarcely different from melite (28 h). 



core. D. core Fldr. is still unknown to me. The description says: ,, Wings above blackish, the inner-marginal 



band anteriorly broader with a discal, shortened oblique band of 4 yellow submarginal spots; hindwing yellow, 

 the whole distal margin proximally above sinuate (or curved), blackish; beneath the marginal spots between 

 the veins are of a deeper yellow, in a brown margin; the hindwing on the whole intensely brown, the basal 

 part of the costa, 2 larger basal spots, and a broad, irregular discal band, traversed by the veins, mother-of-pearl 

 white, in some places with an intense yellow tint, a cu-cular subcostal macula, another one proximally and 

 other thick maculae at the margin intensely yellow. Venezuela, in the Province of Caracas; also from Granada 

 (Colombia). Allied to D. medora (29 b), but larger. The Colombian specimen shows the band of the forewing 

 much broader and connected with the proximal band." 



aWunucula. D. albimacula sp. nov. (192 c) from West Colombia (Rio Magdalena) resembles medora (29 b), but 



it is smaller, the yellow inner-marginal spot of the forewing larger, the yellow subapical spots are absent, but 

 there is a large, white subapical spot situate farther posteriorly. The under surface, especially of the hindwings, 

 as the figure shows, is likewise considerably different. I possess medora from the same habitat. 



D. lygdamis Hew. The $ which was discovered by A. H. Fassl in Coroico, Bolivia, 1400 ra, resem les 

 the $ of lewyi (29 e) above, for the black distal margin of the hindwing is much cleft. The under surface corres- 

 ponds to that of the i;^^, but the yellow spots are larger. 



Of. D. schausii Dgn. (p. 101) we subsequently reproduce the upper surfaces of both sexes, of the ^ also 

 the under surface (192 e). The $ has beneath black hindwings, in the centre is a whitish spot, at the ba.se 

 there are 3 rather large red spots, and the costal margin is dusted with a sulphm'-colour. The forewing 

 is white with a black apical part in which there are 3 whitish-yellow subapical and 2 similar submarginal spots ; 

 the costal margin is also black. The figured specimens are from Peru (Pozuzo). 



iolii)iensi><. D. critomedia-'^ tolimensis Fassl are the $? of critomedia (29 f) from the eastern slope of the Central 



Cordilleras of Colombia (Canon del Monte Tolima, 1200 to 1700 m), not showing white, but yellow ground- 

 colouring above.
