from more northern localities. It does not, however, pass beyond Nicaragua in its 
northern range. In Colombia its place is taken by an allied species, J. diasia, Hew., 
to which it has a great general resemblance, differing, however, in having the quadrate 
spot at the end of the cell of the primaries larger, and in the dark marks of the 
underside being suffused with rufous. 
Our figure is taken from the type specimen sent us from Lion Hill.

This southern species, described originally from Colombian specimens, ranges in 
Central America as far as Costa Rica, whence numerous examples have reached us. 
But little variation is observable in specimens from distant points in the range of the 
species; Central-American examples, however, show a faint extracellular white spot 
on the primaries, hardly visible in insects of more southern origin. 
9. Ithomia jucunda. (Tab. II. fig. 3.) 
Ithomia jucunda, Godm. & Salv. Ann. & Mag. N. H. ser. 5, ii. p. 258. 
I, terre similis, sed macula ad cellule anticarum finem majore et angulo anali per ramum medianum late 
nigrum conjuncta, maculaque rufa in margine late nigro posticarum posita distinguenda. 
Hab. Panama, Candelaria (Ribbe, Mus. Staudinger). 
Two specimens of this [¢homia, obtained by Herr Ribbe are in Dr. Staudinger’s col- 
lection, and are the only ones we have seen. Both are females; and therefore the 
position of the species in the genus Ithomia is somewhat doubtful; but we believe it to 
be a near ally of J. terra. 
Our figure and description are taken from one of the types. 
HYPOLERIA (gen. nov.). 
Lower discocellular of secondaries of male directed across the wing and atrophied at 
its upper end, not meeting the middle discocellular ; middle and upper discocellulars and 
upper radial strong, the latter not uniting with the subcostal at its distal end; lower 
radial very slender, a small recurrent nervule attached to its proximal end. Costal and 
subcostal divergent in the middle, where they enclose an elliptical space, which, how- 
ever, is not closed at its distal end (Section a) ; or costal and subcostal lying close together 
throughout their length (Section 8). 
Secondaries of the female in Section @ with the middle discocellular very short, upper
