378 EHOPALOCEEA. 



a single specimen. In Guatemala it is also found on both sides of the mountain-range. 

 We have also received several specimens from Costa Rica. It is a lowland species, 

 found in hot country between the sea-level and about 2500 feet in the mountains. 



The male genitalia have a short simple tegumen and well-developed scaphium. 

 The harpes are elongated, cleft horizontally towards the end ; the upper portion bears 

 a short tooth, the lower is longer, rounded at the end, slightly serrate on the inner 

 edge, and with a distinct spine near its base. (See Tab. LXXXIV. fig. 11.) 



GORGOPHONE, gen. nov. 



With the coloration and general appearance of Anastrus olscurus and other members 

 of that genus, Gorgophone diifers from Anastrus in wanting the costal fold in the male 

 and also the tuft of hairs attached to the proximal end of the hind tibiae in the same 

 sex. 



Besides the species described below, we have two other similar insects which are 

 quite congeneric. 



1. Gorgophone meliboea, sp. n. (Tab. LXXXIV. figg. 13, 14 s .) 



nastro neceri quoad colores alarum persimilis, sed paulo rufescentior ; alis posticis latioribiis, magis rotun- 

 datis : pedibus posticis pencilla tibiali setosa nulla ; plica alarum anticarum costali quoque absente. 



Hab. Panama, Volcan de Chiriqui, Bugaba (Champion), Chiriqui (Bibbe, in mus. 

 Staudinger). 



We have two male specimens of this species, and Dr. Staudinger has another. The 

 resemblance to Anastrus neceris is very close, and but for the structural differences we 

 should hardly recognize them as distinct. The total absence of the costal fold to the 

 primaries and the tibial tuft to the posterior legs at once reveal its difference. The anal 

 area of the under surface of the secondaries is glaucous- white, just as in A. neceris. 



ECHELATUS, gen. nov. 



This is another small genus allied to Anastrus, differing from it in the absence in 

 the male of the tufts to the hind tibiae. In some species a costal fold is very apparent, 

 but in others much less so. In Anastrus the fold is very small, and in Gorgophone 

 absent altogether ; moreover, the latter genus has the wings shaped as in Anastrus, 

 whereas in Echelatus the primaries are less truncate and the secondaries comparatively 

 smaller. 



The range of the genus extends over the greater part of Tropical America from 

 Southern Mexico to South Brazil.
