Cramer's name for this insect appears to be the oldest, and 

 now that Messrs. Godman and Salvin have taken it as the type 

 of a new genus, lydus Hiibn. beeomes unnecessary. 



On examining a large series ranging from British Guiana to 

 Para, I can find no characters to distinguish ingm and lehena 

 from eryx. Cramer's figure is not a good one, but I think that 

 without doubt it represents the insect which has usually been 

 referred to as T. lehena. It is browner than the common type 

 from Surinam, but I have before me specimens from Para which 

 in this respect closely resemble it. The red areas near the anal 

 angle on imder side of hind wing are more extensive in southern 

 specimens than in those from Guiana, although Sepp's figures 

 show them very distinctly. This author evidently mistook the 

 sexes, as a reference to the plate will show. I have never seen 

 the female. 



Mr. Godman has specimens from Ecuador, Peru, and Bolivia, 

 and these have the blue on the upper side more extensive, 

 especially on the hind wing, which has but a narrow black 

 margin ; but I can detect no other difference. 



Theclopsis c^us. 



Theclopsis cceus Godm. &, Salv. B. C.-A., Lep. Rhop. vol. ii. 

 p. 101, pL 58. figs. 24, 25 (1887). 



It is doubtful if this is distinct from T. deviea Hew. (111. Diur. 

 Lep., Lye. p. 180, pi. 70. figs. 533, 534, 1874), as I find a number 

 of specimens from the interior of Colombia and from Venezuela 

 have the crescent-shaped brand, but are without the patch of 

 shining scales on the fore wing below. For the present, however, 

 I prefer to keep them apart. 



I have seen no females of either form.
