278 EHOPALOCEEA. 



found nearly everywhere in the more open country, from the sea-level to a height of at 

 least 5000 feet above it. 



The male genitalia have an elongated tegumen, which is cleft vertically and ends in 

 two slightly depressed blunt points ; the scaphium is well developed and also long ; the 

 harpagones terminate in a blunt point, and there is a notch or fissure on the dorsal 

 edge. (See Tab. LXXV. fig. 5.) 



11. Eudamus esmeraldus. (Tab. LXXV. fig. 6 a.) 



Goniurus esmeraldus, Butl. Trans. Ent. Soc. 1877, p. 146 \ 



E. proteo similis, sed posticis subtus fasciis obscuris multo magis distincte impressis, maculis basalibus extror- 

 sum albido marginatis, fascia quoque diseali ad angulum analem extrorsum albido limbata, genitalia maris 

 quoque differt. 



Hab. Mexico, Atoyac, Teapa (H. H. Smith) ; Guatemala, San Geronimo, Zapote 

 {Champion); Hondukas, Kuatan I. (G. F. Gaumer) ; Costa Rica, Cache (Rogers); 

 Panama, Bugaba (Champion), Calobre (Arce).— South America generally from Colombia 

 to the Amazons Valley 1 and South Brazil. 



This species is very like E. proteus in its typical form, where the interior of the two 

 dark bands of the secondaries beneath is split up into spots near the costa. It may, 

 however, be usually distinguished by the basal spots of this band and that part of 

 the outer band near the anal angle being edged on the outside with a whitish border. 

 This character would hardly justify its separation from E. proteus were it not supported 

 by a difference in the male genitalia, a very distinct truncate lobe arising from the 

 dorsal edge of the harpes just beyond the fissure (see Tab. LXXV. fig. 6). We have 

 examined several specimens and find this a constant feature. 



E. esmeraldus was described by Mr. Butler from a specimen captured by Mr. Trail 

 at Villa Bella, on the Amazons, on April 15, 1874 1 . We now trace the species over a 

 wide area, which it occupies in common with E. proteus.
