Specific Character. 



T. ahs supra fuscis ; anticis ad basin cceruleis, infra J'errugineis, 

 punctis 2 mediis nigris ornatis ; posticis infra castaneis, antice 

 pallidioribus ^ macvlo nigro ad basin ornatis. 



Wings above brown; anterior blue at the base, beneath ferrugi- 

 nous, with two central black spots ; posterior beneath chesnut, 

 paler on the fore part, with a black spot near the base. 



1 HAVE selected this insect as one of the rarest among a 

 vast number of species of this elegant tribe, collected during 

 my travels in Brazil. Two specimens of the male, and one 

 of the female insect, were captured in the woods near 

 Pernambuco, in lat. 8° 12' S. 



The male insects, in the majority of the Hair-Streaks, 

 have either a velvet or eye-like spot in the middle of the 

 anterior wings, adjoining their outer margin ; these spots are 

 without lustre, and frequently appear as if caused by being 

 rubbed : the colours, likewise, on the upper surface of the 

 wings in the males, generally differ from those of the females. 



Wings brown ; anterior, with the half next the base blue ; 

 central spot blackish, enclosing an obscure eye-like spot 

 margined with grey, the pupil black with a white dot.. 

 Posterior wings two-tailed ; exterior tail very short, interior 

 lengthened : anal anale two-lobed, margin whitish. Ante- 

 rior wings beneath, pale chesnut brown, tips chesnut; in the 

 middle are two black dots, one of which is small ; above 

 these are three others, v.hich form a short transverse line 

 united to the margin. Posterior wings beneath, dark ches- 

 nut; with two central blackish dots in the middle; below 

 are two undulated brown lines, parallel to the posterior 

 margin ; the anterior margin pale, with a large black dot 

 near the base ; anal angle, clouded with grey and tipt with 

 a black spot: another spot is also at the base of the exterior 

 tail. In the female, all the wings above are brown, with a 

 pale blue base ; but the under surface, except in being 

 paler, resembles that of the male.
