ERYCIN A.—LYROPTERYX. 395: 
We include this species in this work on the authority of Boisduval, one of whose 
types of EL. zinna is stated to have been obtained in Nicaragua, but we have no con- 
firmation of its occurrence in Central America. M. Oberthiir has kindly lent us one of 
the types for examination and we have no difficulty in recognizing it as a species 
described by Dr. Felder as E. cacica of Colombia. It is allied to £. huascar, obvious. 
differences being the greater width of the scarlet band of the primaries and the 
opalescent tint pervading it. E. formosa is also allied to it, but the scarlet band on 
the secondaries is wanting in this species. 
LYROPTERYX. 
Lyropteryx, Westwood, Gen. Diurn. Lep. p. 433 (1851). 
Five species are included in this genus, spread from Guatemala on the north to 
southern Brazil in South America; one species occurs within our limits, which has close 
allies in Colombia, the Amazons valley, and Brazil. 
The subcostal nervure of the primaries in the male of L. cleadas emits one branch 
before the end of the cell and two after it; the upper discocellular is not atrophied, it 
makes an acute angle with the subcostal, which it meets nearer the base than the 
upper radial ; the lower discocellular is curved and atrophied in the middle, it joins the 
median beyond the second branch ; the costal side of the cell is longer than the median 
side. The secondaries have a strong basal nervure; the upper discocellular is not 
atrophied and meets the subcostal beyond the first branch at an obtuse angle ; the lower 
discocellular is atrophied in the middle, it meets the median beyond the second branch ; 
the costal side of the cell is much shorter than the median side. In the front legs of 
the male the trochanter is inserted before the middle of the coxa; the femur —4 coxa, 
dilated towards its distal end ; tibia = coxa, dilated towards the middle ; tarsus (single- 
jointed) = femur. Palpi have the terminal joint very small = % middle joint, which 
tapers gradually towards the distal end; basal joint dilated, short = 3 middle joint. 
Antenne have fifty-five joints, the terminal twenty-four forming a very gradual club. 
The tegumen in the secondary organs of the male is normal ; the harpagones are long 
rods bent in the middle and then extending upwards almost to the tegumen ; there are 
patches of strong spines inside the angle, and at the extremity there is a cluster of 
spines. Over the penis there is an arch produced outwards in a point in the middle 
line; at its base on either side is a lobe directed outwards, at the extremity of which is 
a cluster of strong spines.
