We are in some doubt if this is the true UW. telegone of Boisduval, whose figure is 
anything but satisfactory, nor does Hewitson much mend matters, and adds a further 
complication by figuring an obvious female asa male. Two of Dr. Felder’s YW. amiana 
are before us, and we have little doubt that this name refers to the same species, 
though there is a slight difference in the female, which has much less blue on the 
secondaries. 
n examination of Hewitson’s specimens of I. lamachus in the British Museum, 
and of the specimens figured as MM. telegone, we believe them to be referable to the 
same species. 
Examples from Costa Rica have the bands of the secondaries unusually broad, and 
this is also seen in some Veraguas specimens, but it is not to be considered a specific 
character. 
M. telegone differs from M. methion in having the blue of the secondaries in the 
male of one tint, whereas in the allied species the costal half is of a deep blue, and the 
rest of the wing much duller in tone. 
This Mesosemia is one of the commonest of its genus in the country in which it is 
found.

This species is the northern form of I. telegone, taking its place in Mexico and 
Guatemala. From the former country there is a female specimen in the British 
Museum, and Boisduval mentions one from the same country under the name 
MM. lamachus.
