18 KHOPALOCEKA. 



A species of very wide range, extending from Guatemala in the north to South-eastern 

 Brazil, being apparently most abundaut in Guiana and the Amazons valley. In Central 

 America, though widely distributed, T. hemon cannot be considered common, as we have 

 but few specimens from any portion of our country. There is some variation apparent 

 in the upper surface of the wings, which may be partly due to the age of the specimens. 

 The female is very similar to that sex of T. mavors, but may readily be distinguished by 

 the black spot near the middle of the costa of the secondaries beneath. The figure 

 represents a male from Veraguas.

South America, Colombia to Guiana 1 and Amazons valley 2 . 



This is a very abundant species throughout the northern portion of tropical America. 

 It was described by Hiibner from Guiana specimens, and has since been traced throughout 

 the Amazon region and as far northwards as Southern Mexico. It inhabits the low- 

 lying districts, 3000 or 4000 feet being probably its extreme range in altitude. 



Our series of specimens show hardly any variation ; southern examples are perhaps 

 rather bluer in tint, and have the dark transverse lines on the secondaries beneath more 

 strongly impressed. 



f". No fold on the secondaries near the median nervure beneath. (Species 16-25.) 



et". Terminal joint of palpus in male and female subequal; a double alar stigma.
