guished by the absence of the yellow costal margin of the primaries. The examples 
from Guatemala are considerably smaller than those from Mexico. 
AREVA. 
Areva, Walker, Cat. ii. p. 525. 
This genus was founded by Walker for the reception of an insect from Venezuela; it 
is most nearly allied to the preceding genus. The species are by no means common in 
our country; but from South-east Brazil I have long series of several undescribed 
forms that seem to occur most abundantly, judging from the numbers received. 
1. Areva laticilia. 
Areva laticilia, Walk. Cat. ii. p. 526"; Butl. Trans. Ent. Soc. 1877, p. 358. 
Hab. Guatemata, Volcan de Atitlan 2500 to 3500 feet, Las Mercedes 3000 feet, 
San Gerénimo, Cubilguitz (Champion); Costa Rica, Irazu (Rogers); Panama, Bugaba 
800 to 1500 feet (Champion).— VENEZUELA }, 
This species appears to be very widely distributed, but by no means common. 
It is frequently to be found at Bugaba in the early moming, sitting upon the leaves of 
growing rice cultivated in the forest-clearings of the “tierra caliente” (Champion). 
2. Areva leptalina, sp.n. (Tab. XIII. fig. 5.) 
Primaries dusky white, shaded along the inner margin and across the middle with pale brown; secondaries 
brownish white, shaded with brown on the outer margin: head and thorax brown; abdomen wanting ; 
legs brownish white. Expanse 1} inch. 
Hab. Costa Rica, Cache (Rogers). 
A single specimen, in poor condition. It is a very distinct species, allied to A 
laticilia, Walker. 
3. Areva marginata, sp. n. 
Primaries silky white, the inner margin from the base to the anal angle streaked with brownish black ; secon- 
daries dusky white, almost white at the base, but darker in the female than they are in the male: head, 
thorax, and abdomen brownish black, the anal tufts of the male black; antenne and legs brownish black. 
Expanse, ¢ 1 inch, 9 14 inch. 
Hab. GUATEMALA, Cubilguity, Chiacam, Cerro Zunil (Champion); Costa Rica, Trazu 
6000 to 7000 feet, Rio Sucio (Rogers). 
This species resembles Crambomorpha umbrifera, Feld. 
EURYLOMIA. 
Eurylomia, Felder, Reise Nov. Lep. iv. t. 105. f. 26, Index, p. 5. 
Eurylomia was founded by Dr. Felder for the reception of a species from Mexico; it 
seems to be most nearly allied to the preceding genus, but very distinct.
