323 Mr. E. G. Joseph on the Rhopalocera 



Burchell's specimen (1298) departs from the pattern of 

 numatus superioris as represented by Stichel in Wytsman's 

 ' Genera,' p. 7, fig. 2, in the fact that the three subapical 

 yellow spots, characteristic of the fore wing upper surface, are 

 evanescent, although just visible. The faint indications of 

 two additional pale spots nearer the apex can also be made 

 out on the fore wing of 1296. These spots, which are more 

 distinct and white on the under surface, resemble those 

 figured in the var. genii nata (Stichel, I. c. p. 7, fig. 3). 



Westwood's list agrees : but he united this specimen and 

 Hel. ethilla numismaticus ' under one species, Hel. numata 

 (see 1299). Opposite to the list of dates he wrote, " Heli- 

 conia Numata: maculis 3 flavis ad apicem alar. antic m . : mac. 

 marg. al. post, flavis." — Moreover, between the " 3 " and 

 " flavis" he drew a diagrammatic representation of the three 

 yellow spots. The patterns of the three individuals placed 

 under numata by Westwood (1296, 1299, and 1300) are 

 remarkably similar, — least so in the case of 1299, which he 

 thought was perhaps a variety of this species. See also the 

 observations made under 1299. 



Heliconius silvana silvana, Cram. 



15. 11. 29. = 1297. Pard. S. Jose". " Caminho de Cha- 

 m6nte." A Westwood's label reads, " Hel Sylv ina." 

 Westwood's list agrees, and the following description is 

 written opposite to the date of this specimen : " Heh'conia 

 Sylvana : alis ant 8 , ultra cellulam fasc. 2 macularibus flavis." 



Heliconius silvana robigus, Weym. 



21.3.26. =1298. Rio de Janeiro. "Along the Carioca 

 Aqueduct." A Westwood's label reads, " Sylvanw prop. 

 Mac. 1 alba." 

 By the last words Westwood undoubtedly refers to the 

 large, conspicuous submarginal spot of the hind wing, which 

 is also the first counting from the costa. This spot is, how- 

 ever, yellow and not white on the upper surf ace, as Westwood 

 clearly pointed out when he described the same specimen 

 (1298) in his list, writing opposite to the date 21. 3. 2Q : — 

 " Hel. Sylvance proximo : alis ant 8 , ultra cell, fascia subapicali 

 flava : al. p. puncto unico flavo anguli externi." There is, 

 in fact, no white marking on the upper surface of 1298, but, 

 on the under surface, the corresponding spot is white. It is 



1 In Stichel's classification, which is here followed, numatus is separated 

 from ethilla by silvcma.
