beneath the penis, near its proximal end and slightly diverging from it, is another: 
chitinous piece; towards its distal end it turns upwards and bifurcates laterally, each 
fork terminating on the inside with a roughened pad without sete.

Of this southern species we have received a few specimens from widely distant points: 
within our limits, where it must be a scarce insect. The most northern examples 
hardly differ from others from the Amazons valley, except, perhaps, that the band of 
the wings is rather wider, whiter, and less fawn-colour. 
Mr. Champion only met with this species in the forest-region of the “tierra. 
caliente.” 
CYRENIA. 
Cyrenia, Westwood, Gen. Diurn. Lep. p. 435 (1851). 
If we except Erycina belphegor of Westwood, doubtfully referred by Mr. Bates to: 
this genus, there are but two closely allied species of Cyrenia, one of which ranges 
over the Amazons valley, the other is found in Panama. Mr. Bates places it between 
Lyropteryx and Hades in his Monograph on the Erycinide ; but it seems to us to have 
no very near connection with either form. 
The subcostal nervure of the primaries in C. martia emits one branch before the end 
of the cell and two after it; the discocellulars are nearly in a line and atrophied towards. 
the middle ; the upper discocellular makes an acute angle with the subcostal, meeting 
it at the same point as the upper radial; the lower discocellular meets the median at 
right angles at a little beyond the second branch; the costal side of the cell is 
considerably longer than the median side. The secondaries have a strong basal 
nervure ; the discocellulars are atrophied, the upper meeting the subcostal at an obtuse 
angle a little beyond the first branch, the lower the median a little beyond the second 
branch ; the costal side of the cell is shorter than the median side. 
The front legs of the male have the trochanter inserted in the middle of the coxa ;
