440 HETEROCERA. 
the densely-forested Atlantic slope of Guatemala. It is in all respects very different 
from any other member of the family known to us, but comes nearest to Boana cataleuca 
(Herr.-Schaff.). 
TOMYRIS, gen. nov. 
Allied to Ogoas, from which it differs as follows :—The primaries are narrower and slightly longer, and more 
pointed at the apex, and on the inner margin on the underside they have a tuft of long hairs; the 
secondaries are shorter and more rounded ; the antennw are considerably longer, being two-thirds the 
length of the wing; the palpi are much larger and longer, projecting out straight from the head. The 
thorax and the abdomen are slender, the abdomen extending beyond the wings ; the legs are long and 
slender, and not clothed with hairs. 
Type Tomyris nigropuncta. 
The tuft of long hairs on the inner margin of the primaries beneath distinguishes 
the genus from Ogoas, which has the tuft of hairs on the costal margin of the secon- 
daries above. 
1. Tomyris nigropuncta, sp.n. (Tab. XXXV. fig. 25, 3.) 
Male, Primaries fawn-colour, shading to dark brown along the costal margin, apex, and outer margin, a very 
faint line crossing the wing beyond the cell, and a submarginal row of black spots extending from near 
the apex to the inner margin close to the anal angle, the last two spots in the submarginal row considerably 
larger than any of the others; secondaries blackish-brown, the costal margin broadly bordered with pale 
silky-brown, a small black spot edged with white below the middle of the wing and nearest the anal 
angle, the marginal line black; the fringe of both wings dark brown ; the underside of both wings 
uniform pale blackish-brown, the inner margin of the primaries almost to the anal angle silky-white : 
head, antennz, and thorax pale brown, the palpi black; the abdomen above blackish-brown, beneath and 
the legs pale brown, Expanse 1,8, inch. 
Hab. Guatemana, Volcan de Atitlan 2500 to 3500 feet (Champion) ; Panama, Caldera 
in Chirigui 1200 feet (Champion). 
We have only received two specimens of this insect, both males; the one from 
Caldera is considerably paler in colour. The specimen from the Volcan de Atitlan is 
figured. 
HORMISA. 
Hormisa, Walker, Cat. xvi. p. 74 (1858), & xxxiv. p, 1144. 
Walker founded this genus upon an insect from North America, and afterwards 
added to it a second species from the same country; two others are here described, both 
from Chiriqui. Grote does not mention either of Walker’s species in his Check-list. 
1. Hormisa absorptalis. 
Hormisa absorptalis, Walk. Cat. xvi. p. 74( 3) 1. 
Hab. Nortu America, United States \—Mexico, Valladolid in Yucatan (Gaumer) ; 
Panama, Taboga Island (Mathew, in mus. D.). 
Of this insect we have received two specimens, these being almost identical with 
Walker's type in the National Collection.
