304 EHOPALOCEEA. 



long, more than two-thirds the length of the costa, the upper discocellular short, the 

 middle slightly shorter than the lower and in a straight line with it ; the third median 

 segment more than half the second, and with a recurrent nervule proceeding from near 

 its middle. The secondaries have a well-defined anal lobe ; the discocellular is evanes- 

 cent, and there is no radial ; the second median branch starts from before the end of 

 the cell, the second median segment being considerably shorter than the first. The 

 terminal joint of the palpi is short, small, and subconical ; the club of the antennae 

 abruptly thickened and ending in a fine hook, the latter being considerably shorter than 

 the rest of the club. 



The range of the genus coincides with that of the species which follows,

A species of very wide range over nearly the whole of Tropical America, and appa- 

 rently common everywhere. In the size and position of the hyaline spots of the 

 primaries little variation can be traced; but the general colour of the hmd wings 

 beneath is in many specimens of a greyish tint, in others a purple shade is distinctly 

 visible. The spot near the base of the secondaries beneath in the angle between the 

 costal and subcostal nervures is very characteristic of the species. 



The male genitalia have a long narrow tegumen with a lateral depressed point near 

 the end on either side ; the scaphium is as long as the tegumen and lies close to it on 

 the underside, and has a granular patch at the end ; the harpes have a deep notch 

 on the dorsal edge, beyond which is a serrated lobe, the end being truncate (See 

 Tab. LXXVII. fig. 9.) v
