1907.] BUTTERFLIES OF THE FAMILY LYCJSNIDyE. 595 



subcostal nervure on the upper side of hind wing. Mr. Godman 

 has two females from Haiti, which have lost the gi'eenish tinge on 

 the ground-colour below, but this may be due to their being some- 

 what faded. 



Thecla delicIvE, sp. n. (Plate XXXV. fig. 3.) 



Male. Closely allied to T. cyllarus Cr. *, from which it differs on 

 the under side in the entire absence of the narrow black zigzag 

 lines and shades. Both the red patches at the anal angle are 

 large and prominent and are connected by a narrow red line. 

 The patch of scales on the under side of the fore wing is large, 

 blackish, and prominent as in T. cyllarus. 



Expanse 14- inch. 



Hah. Maranham, N. Brazil. 



Type, Mus. Godman. 



This insect may prove to be an aberration of T. cyllarus Cr., but 

 amongst a large series of that species I am unable to discover any- 

 thing approaching it. It has a very distinct appearance. 



Thecla porphyritis, sp. n. (Plate XXXY. fig. 4.) 



Male. Allied to T. cyllarus Cr., from which it differs on the 

 under side in the ground-colour being much darker and the white 

 mai'kings more prominent and in the glandular patch on the fore 

 wing being quite small, nut-brown, and close to the base ; the 

 inner margin being broadly pale and the discal portion of the wing 

 above the submedian nervure having a silky appearance. 



Female. Both surfaces slightly paler than male, but the area of 

 blue on the upper surface is scarcely less. 



Expanse 13^ inch. 



Hah. Tapajos and Para, Brazil. 



Types, Mus. Godman. 



Mr. Godman's collection contains male and female from Para 

 and male from Tapajos from Bates's collection, which were un- 

 identified by him, a,nd male from Para captm-ed by H. H. Smith. 



Thecla tyriam, sp. n. (Plate XXXV. fig. 5.) 



Male. Allied to Thecla perola Hew.t, having the same broad 

 silky costal margin to hind wing above, but with the blue area 

 along the inner margin of the fore wing less extensive and not 

 reaching nearly to the outer angle. On the under side the ground- 

 colour is much paler, and the large black glandular patch on the 

 fore wing of T. perola is replaced by a smaller, pale straw-colour 

 patch, paler than the ground-colour of the wings. 



Expanse Ig-lj^y- inch. 



Hah. Para, Brazil {H. H. Smith). 



Type, Mus. Godman. 



* Papilio ci/llarus Cr. Pap. Exot. i. pi. 27. C, D (1775).
