Mention has been made in the key (anted, p. 176) of the restricted number of abdominal segments on which 
the supplementary longitudinal carina is present in this species. This is a feature not mentioned in any 
of the preceding descriptions’—*, although McLachlan’ has mentioned certain “ lateral depressions” 
which are apparently those lying below the supplementary, and above the ordinary, longitudinal carine.

Fronto-nasal suture with a dark brown, almost black, line in the Chiriqui male; superior appendages (6 mm.) 
longer than the ninth abdominal segment (5 mm.) in both the present males, as Brauer’s figure, but not 
his description *, represents. The inferior appendage has a superior, basal, triangular process which 
projects upward and backward between the right and left superior appendages at their base; although 
well-developed, it is not mentioned in the descriptions; its morphological significance will, doubtless, be 
interesting. The two males before me differ slightly from each other in the shape of the superior lobe, 
situated just before the middle of the superior appendages, and in the slenderness of the inferior 
appendage. 
Antecubitals : front wings 29-30, the first and tenth or eleventh thicker; hind wings 19-22, the first and 
eighth, ninth, or tenth thicker. Postcubitals: front wings 23-26, hind wings 25-28. Discoidal
