nervule) near its upper end; middle discocellular gradually curved ; upper discocellular 
very short, meeting the subcostal at about three fourths of its length from its base ; 
cell moderately short, but proximal segment of subcostal longer than the three median 
segments; costal and subcostal nervures gradually divergent, but the former approaches 
the latter near its distal end. Secondaries of female with a short upper discocellular. 
Tarsus of front leg of female with five joints, with a pair of spurs on each of the 
second and third joints. (Type Jthomia tutia, Hew.) 
This section of Jthomia comprehends about eight or nine Tropical-American species, 
all more or less nearly allied. Two of these penetrate into Central America. As 
a group Calloleria seems allied to Epithomia; but the costa of the secondaries is less 
highly arched, the palpi seem less hairy, and the distal segment of the subcostal 
nervure much longer in proportion to the length of the nervure itself.

The Amazonian locality assigned to C. twtia by Hewitson! is no doubt erroneous, as 
Mr. Bates has already pointed out”, indicating its correct habitat as Venezuela. We 
possess a specimen from the Sierra Nevada of Santa Marta precisely like Hewitson’s 
figure, thus confirming Mr. Bates’s statement. 
The range of ©. tutia seems to be completely broken in the State of Panama, where 
C. azara takes its place. In Costa Rica, however, the two forms blend to some extent ; 
but the true C. futia reappears in Nicaragua, uninfluenced by contact with C. azara. 
The intermediate forms are characterized by the varied extent of the pale subapical 
patch of the primaries, it being well developed in C. tutia and altogether absent in 
C. azara. It would seem as if C. azara were the agressive form, and that it was 
gradually displacing C. tutia in the Central-American localities where the latter is 
found. We have not seen any Costa-Rican specimens wholly of the pattern of C. azara. 
The insects referred to that race by Messrs. Butler and Druce* have all some of the 
characters of C. tutia; and, though doubtless intermediate between the two, we place 
them under the latter name. |
