 and well-marked acuminate tail of TJ. ehuleata \ as in the latter 

 species, the disk of the wings, and especially of the secondaries, 

 i:i crossed by a band of grey scales much better-defined than in 

 TJ. maculicaudaria, and the spots on each side of the tail of 

 secondaries are reduced to mere black points ; the bands are 

 narrower and not so dark as in the last-mentioned species, the 

 inner one somewhat concave, darker and wider apart than in
