A “mixed-front” is presented in two males from near Coroico, Bolivia, of rather 
larger size (abd. 22, hind wing 27-28 mm.), taken April 29 and May 31; the face is 
distinctly reddish in the younger of the two, but a violaceous tinge is apparent on the 
upper surface of the frons; in the other the labrum is still reddish, clypeus obscure 
brown, frons mixed red and blue. ‘These males therefore furnish intermediates 
between d and @’. Mixed red and blue fronts exist in otherwise blackish-faced males 
cited above from Amula and Tepetlapa. 
[e’ and intermediates between d’ and e’. 
3. Abdomen 20°5-22 (Casiguana), 18-19 (Brazil); hind wing 25-27 (Casiguana), 24-25 (Brazil) mm. 
The Rio and Nova Friburgo males seem to be exactly similar to the e specimens from the same localities 
except for the colours of the frons and face, the darker tint of the body and of the wing-bases; two of 
those from Rio have the labrum pale reddish. 
2. Abdomen 19-20, hind wing 24°5-26 mm. (Casiguana).

The Casiguana specimens were taken in May.

* One male in the M.C. Z. labelled simply “ Brazil” seems to belong here, but is very large: abdomen 23'5, 
hind wing 31:5, stigma of front wing 4 mm. ; antecubitals, hind wing, 9, 10.
