6U2 MR. H. H. DRUCE ON NEOTROPICAL [June 18, 



No two specimens are identical, but the northern specimens 

 are usually, although not invariably, whitish on the under side. 



This species is not included in the Biologia Centr.-Amer., as 

 Mr. Smith's captures were doubtless received after the Theclas 

 were completed, and the only example from Panama, is a female. 



Thecla venustus, sp. n. (Plate XXXYI. figs. 3 c? , 4 5 .) 



Male. Allied to T. echion Linn, {crolus Cr.). Upper side shining 

 violaceous blue ; costa and apical half of fore wing dark brown ; 

 a darker patch at the end of the cell. Hind wing : inner margin 

 narrowly brown, a fine anteciliary black line, inwardly bordered 

 by a white line towards the anal angle. Lobe black, with some 

 orange scales. Cilia of fore wing bright cupreous, of hind wing 

 brown at the apex, whitish towards the anal angle. Under side : 

 bands and spots arranged as in T. echion, but faintly outlined 

 with black although clearly bordered with white. The ultra- 

 median band on the fore wing is straighter and the ground-colour 

 is darker than usually obtains in T. echion. 



Femcde. Upper side : fore wing pale brown, greyish at the base, 

 a large darker patch beyond end of the cell. Hind wing pale grey, 

 darker towards the base, slightly opalescent ; inner margin broadly 

 pale brown. A marginal row of dark brown spots from the 

 apex to the anal angle where they become largest, placed between 

 the nervules. An anteciliary black line. Tails black, bordered 

 and tipped with white. Cilia of fore wing reddish brown, of 

 hind wing pale grey. Under side as in male, but ground-colour 

 paler.

JIab. Chapada Campo, Brazil {H. H. Smith). 



Types, Mus. Godman. 



Mr. Godman's collection contains six specimens which show no 

 variation. The violaceous blue and the bright-coloured cilia 

 should easily distinguish this insect from its allies. The speci- 

 mens were captured in November and December. 



Thecla labes, sp. n. (Plate XXXYI. fig. 6.) 



Male. Upper side dull olivaceous brown ; a large black patch 

 occupying the whole of the cell of the fore wing ; abdominal half 

 of hind wing suffused with greenish-blue scales when held at an 

 angle ; abdominal margin brown. Cilia of fore wing brown, of 

 hind wing paler. Underside markings as in T. echion L. 



Expanse -f-^ inch. 



Hah. Cunapo, Trinidad {F. Birch). 



Type, Mus. Druce. 



At one time it appeared that this insect might be a diminutive 

 example of T. echion, which it closely resembles on the under side, 

 but the upper surface is so diflferent that I think it requires a 

 name. 



Mr. Birch captured it on 21st June.
