192 Mr. W. J. Kaye's Catalogue of the 



142. Tmolus beon. 



Papilio Icon, Cram., Pap. Ex., iv, t. 319, B. C. (1782). 



Range. Eastern Brazil; Venezuela. 



It is very difficult to say whether we have one or more 

 species to deal with. Tmolus hactra, Hew., looks distinct 

 from heon, but it may only be a form of it. The amount 

 of blue on the hind-wing cannot be considered as ever 

 constant. We know that in certain Palsearctic Lycc'enidiB 

 the first brood has often much bluer $ $ than the second 

 brood, and some localities never yield a blue-tinged ^ at 

 all. The red inner edge of the transverse line on the 

 under-side of the fore-wing of heon fades considerably with 

 age, and some specimens (if they are undoubtedly heon) 

 have hardly a trace of the red colouring. My own series 

 is composed of four large males taken by my brother at 

 Verdant Vale in the autumn of 1895, and which scarcely 

 have any blue on the fore-wing except on the inner margin ; 

 five (^ (^ and two ^ $ are heon as figured by Cramer ; one $ is 

 the haetra of Hew.; and one $ is very like typical heon, but 

 with much less blue on the hind -wing, while one is exactly 

 like heon on the upper-side but has no trace on the under- 

 side of the red edging to the transverse line. The species 

 is exceedingly abundant nearly everywhere. It should 

 perhaps be added that some specimens have a different 

 lustre to the blue colouring on the hind-wing. The 

 specimens alluded to from Verdant Vale are very pale 

 blue and not nearly so lustrous as the others. 



143. Tmolus unilinea, n. sp. 



Upper-side of both fore- and hind-wing extremely like crohos, Cr., 

 the brand on the discocellulars of fore-wing is however larger and 

 browner in colour. Under-side white ; fore-wing with a line 

 composed of brownish-yellow spots commencing immediately below 

 costa and finishing at nervure 2, the upper spots very small, the 

 lower ones gradually becoming larger ; outer margin just slightly 

 shaded with greyish. Hind-wing with a large orange blotch just 

 above the cell between nervures 7, 8, an elongated blotch between 

 nervures 4 and 6, a small elongated spot immediately below the cell 

 and a further small spot immediately above nervure lb. Near the 

 outer margin between nervures 2, 3, is a yellow spot with a black 

 centre. At anal angle there is some faint yellowish colour. 



Exp. 30 mm.
