90 ISlr. R. M'Laclilan o?i Calopterijgina 



Legs black ; the inner side of the femora greyish or 

 whitish, excepting at the tips. 



Length of abdomen, 42 mm. Length of posterior 

 wing, 06 mm. Expanse of wings, 77 mm. 



Chairo, Bolivia. One mature $ . 



Apparently intermediate between T. picta and T. 

 Batesi: remarkable for the Avings being nearly entirely 

 opaque ochreous before the dark apical portion. 



Thore cBquatorialis, Selys (race ? of albovittata 

 according to De Selys). 



Since the type was described I have received three 

 other examples from Intaj (all females), that appear to 

 belong here. All are rather larger (posterior wing 

 40 mm.). One is matm^e, without a vestige of the milky 

 l)and ; the others immature, as indicated by the ptero- 

 stigma, w^liich is pale brown. In these immature exani- 

 l)les the milky band is clearly visible, especially on the 

 ])osterior wings, and is margined externally by smoky 

 greyish-brown; its position and direction as in the type 

 of CBquatorialis and not as m albovittata. The ptero- 

 stigma surmounts from six to nine cellules. The $ of 

 this species (or race) is still a desideratum. 



Cora duo lis, n. sp. 



Wings rather broad ; nodus placed much nearer to the 

 base of the wing than to the origin of the pterostigma, which 

 is dark brown, short (2 1 mm. long), very thick, surmounting 

 4 — 5 cellules; 32 — 35 antecubital and 45 — 47 postcubital 

 nervules in the anterior Avings ; 4 — 5 sectors interposed 

 between the first and second sector of the triangle ; the 

 second of the triangle longly and regularly trifurcate. 



^ . Wings hyaline, the posterior margin fiiintly tinged 

 with yellowish, with the appearance of a whitish spot on 

 the anterior margin just beyond the nodus, caused by the 

 neuration at that point being milky Avhite, instead of 

 black like all the rest. Labrum and cheeks brownish- 

 yellow; nasus Avith a brownish-yellow spot on either side ; 

 upperside of head with four brown spots (in two rows) 

 anteriorly, and the posterior margin with a narrow brown 

 continuovis line ; basal two joints of antenna? yellowish 

 above. Prothorax with two very large lateral spots, and 

 a small median, brownish-yelloAV ; its lateral margins
