228 Mr. H. W. Bates's Contributions. 



male sex have this rharacter; he says also that the abdomen is "sometimes 

 whitish and sometimes blackish ;" but, in fact, the white colour of the abdomen 

 is proper to the $ alone. In Boisduval's collection, a specimen of 5 Lycidas 

 stands as P. Belus, Cramer. Belus difTers from Lycidas, both ^ and 9 , ia 

 many points. The dark, almost uniform bronzed-fuscous colour of the fore wings, 

 and the concolorous abdominal fold of the hind wings (the latter character very well 

 shown in Cramer's figures) are two of the principal points of distinction. Lijcidas 

 has, in both sexes, a long stripe of a pale yellow colour along the inner side of 

 the abdominal fold. Beius occurs in its typical form on the Amazon, only in the 

 upper region. According to Cramer it is found also at Surinam. In other parts 

 of tropical America, from South Brazil to Mexico, it appears to be transformed 

 into a number of strongly-marked local sub-species. It is a rapid and bold flyer, 

 and not an abundant species. 



P. Varus, Kollar, Beitr. Ins. Fauna, N. Gran. t. 1, f. 3, 4 ? 



I captured a specimen (and saw many others) of a $ Papilin, which resembles 

 very much the figure given by Kollar ; at flowers on the borders of the forest at 

 Ega. on the upper Amazon. I suspect it to be the $ of Belus. The true Belus, 

 however, I have not yet seen from New Granada, the locality of Kollar's insect. 

 A local representative, or sub-species of Belus, the P. Lnodamas of Felder (Wien. 

 Ent. Monatschr. iii. t. 8, f. 1), however, comes abundantly in collections from 

 that countiy. It is possible that the P. Varus is the 5 of Landamas, in which 

 case the females of the two allied forms will resemble each other more than do 

 their respective males. 



P. Numitor, Cram. 113 B. 



This is the local form, or sub-species of Belus, which appears to take its place 

 in the Par& district ; in the same way as Laodamas dues in the Andean valleys of 

 New Granada. Cramer's figure is not sufficient to characterize the species. On 

 this account, as well as to distinguish it from P. Laodamas, I add a short descrip- 

 tion of it. ^ rather smaller than P. Belus. Fore wing pointed, outer margin 

 very nearly straight; bronzed-fuscous, with a silky gloss ; beneath brown, spotless. 

 Hind wing above dark green, glossy ; outer margin darker green, with a suh- 

 marginnl row of four or five angular lunules of the ground colour of the wing ; 

 a large, oblong, obliquely-truncated, yellowish-white spot in the middle of the 

 cosia, and a row of six smaller, rounded, powdery spots of the same colour across 

 the middle of the wing between the nervures and a little exterior to the cell ; be- 

 neath dark-brown, with a sub-marginal row of seven large, rounded, sub-lunular 

 red spots, broadly margined with black. Inside of abdominal fold concolorous, 

 as in P. Belus. Body and fringe of the wings as in P. Belus. 



P. Lycidas, Cram. 113 A. ? ; 113 C. S (P- Erywanthus). 

 The male found at Par4. on the borders of rivulets, in the forest and at Ega, 

 abundantly at the commencement of the ebb season, viz. in June and July, in 

 company with P. Belus. It differs from Belus, besides the white stiipe within the 

 abdominal fold, by the lighter, clearer green colour of the fore wings, which are 

 darker only along the basal half of the costa. The fore wings are also more 

 produced at the tip. The pale spot of the costa of hind wings is small, rounded 

 and placed near the external angle of the wing. There is, in some specimens, 

 a row of small pale spots across the middle of the hind wing ; varieties strongly 

 marked in this respect would agree with Cramer's description of Numitor (vol. ii. 

 p. 25), did not his figure show the concolorous abdominal fold. The 5 I have 

 seen in Dr. Boisduval's collection ; it agrees very well with Cramer's figure, 

 113 A ; the specimen was from Cayenne. The species is therefore now known 

 from Surinam, Cayenne and the most humid parts of the forests of the Amazons. 

 I have not seen it from any other part of America. 



P. Pulydamas, Lin. Cram. 211 D. E. and authors. 

 A species widely distributed in Tropical America, being found from Rio 

 Janeiro to Nicaragua. On the Amazons it frequents gardens and semi-cultivated 

 or neglected grounds, making it probable that it, as well as many other species of 

 the same habits and same wide distribution, have been introduced with the 

 clearing of the forests by man.
