582 MR. H. H. DRUCE OK NEO'tROPiCAL [June 18, 



Hah. Bogota, Colombia [Wheeler). 



Type, Mus. Goilman. 



A very beautiful species Avith many points of distinction. 



Thecla bavus, sp. n. (Plate XXXIII. fig. 12.) 



Male. Allied to T. minyia Hew., with the brand circular and 

 smaller. Uj)per side with the blue areas paler, more saturated and 

 somewhat less extensive. Under side uniform russet-brown 

 shading to dark greyish towards the disc of the fore wing and 

 broadly pale grey along its inner margin. On the fore wing is 

 an oblique central Avhitish band, commencing on the costa (where 

 it is bi'oadest) and ending about the centre of the disc. On the 

 hind wing, near the costa and towards the base, is a small, 

 distinct, white spot edged inwardly with black ; an ultramedian 

 sinuous line also inwardly edged with black ; a dark spot at the 

 extreme anal angle and above this patches of bluish and yellowish 

 dusted scales. Abdomen greyish above, pale below. Frons 

 russet-brown. 



Expanse 1-3- inch. 



Hah. Amazons {Wallace). 



Type, British Museum. 



Thecla color, sp. n. (Plate XXXIII. fig. 11.) 



Male. Form, size, and general appearance of T. athymhra Hew., 

 but bkie brighter and more clearly defined without any brands 

 as in that species, but on holding the insect before a strong light, 

 a large dark patch can be discerned occupying the outei- half of 

 the cell of the fore wing. Under side much paler, the pinkish 

 basal areas scarcely discernible, and an additional ultramedian 

 linear band of lunules in the fore wing. 



Expanse li inch. 



Hab. British Guiana (Whitely). 



Type, Mus. Druce. 



There are also two specimens in Mr. Godman's collection 

 captured by Whitely at Aunai, on the Essequibo River, in the 

 same country. 



This is an interesting species and, although it is without the 

 distinct double brand of T. athymhra, is probably allied to it. 



Thecla amplus, sp. n. (Plate XXXIII. fig. 13.) 



Male. Allied to T. ophelia Hew.* Brand smaller, black, and 

 much less prominent. Upper side : blue areas more extensive, of 

 a more purple hue and less shining. Under side difiers from that 

 of T. ophelia in the red basal blotches being much reduced, so 

 that the margins of the wings only are red, in having a distinct 

 median costal spot on the hind wing outwardly edged with white, 

 and in the marginal spot between the submedian nervule and the 

 lower median nervule, which in T. ophelia is always black, being 

 thickly dusted with light bluish scales.
