HELICONIDZ—ITHOMIA. 
ITHOMIA DERCETIS. 58. 
I. Dercetis. Doubleday & Hewitson, Gen. Diur. Lep. Pi. 18. 
Uprrrstpn. Male transparent rufous-white, glossy; the margins (very narrow), 
and the nervures (except where they cross the yellow band of the anterior wing) dark 
brown. The band at the end of the cell very narrow, curved, followed by a broad 
sinuated band and a marginal spot of yellow. 
Unpersipe as above, but lighter. 
The female differs from the male, only in having the margins and band rather 
wider. 
Expan. 235 nm. Hab. Venezuela. 
Tn the Collections of W. W. Saunders and W. C. Hewitson. 
I have repeated here drawings of I. Dercetis and Morgane to make this beautiful group of but- 
terflies, of which we have already figured sixty-one species, more perfect. 
ITHOMIA MAKRENA. 59. 
I. Makrena. Hewitson Exot. But. Ithomia, fig. 29. 
The butterfly now figured differs remarkably in size, and also in the depth of colour, from 
that which is represented at Fig. 29, but in every other respect they are alike, and I have no doubt 
are the same species, having seen one which is intermediate. When I described the butterfly at 
Fig. 29, I stated my belief that it was probably only a female variety of Phenomoe, of the Genera 
of Diurnal Lepidoptera. Having since then received a male of Makrena, I find they are distinct, 
although most closely allied. The male of Makrena has the apex of the anterior wing more pointed, 
the margins broader and much darker ; and on the underside the apex of both wings and the margin 
of the posterior wing are marked with white spots, whilst the male of Phenomoe is without any, and the 
female has them only on the apex. I shall hope to figure the male of Makrena and both sexes of 
Phenomoe on a future plate. 
ITHOMIA PENINNA. 60. 
Uprrrstpr. Male transparent clouded lilac-white; the nervures and margins 
(the immer margin of the anterior wing broad) brown. Anterior wing with an oblique 
spot across the middle of the cell, and a curved band at the end of the cell brown ; 
clouded from the band to the apex, leaving several light submarginal spots. Posterior 
wing with the outer margin near the apex broad, enclosing a round spot. 
UNDERSIDE as above, with all the brown rufous. 
Expan. 233 in. Hab. Bolivia.
