206 HETEROCERA. 
8. Hydrias limba, sp.n. (Tab. XXII. figg. 43,59.) 
Male. Primaries brown, palest close to the base, and crossed about the middle by a wide dark brown band 
edged with paler colour; secondaries uniform slaty-brown, slightly paler at the base: head, thorax, and 
abdomen dark brown; antenne and legs brown. Female like the male, but larger and slightly redder in 
colour. Expanse, 3, 14 inch; 9, 2 inches. 
Hab. Costa Rica, Irazu 6000 to 7000 feet (Rogers). 
Rogers only obtained a pair of this distinct species; it is allied to H. guttularis. 
4, Hydrias guttularis. 
Hydrias guttularis, Walk. Cat. vi. p. 1402". 
Hab. Mexico, Cordova (Riimeli) ; Honpuras (Dyson *). 
We have received a single specimen of this species from Mexico ; it agrees well with 
the type in the British Museum. 
5. Hydrias larunda, sp.n. (Tab. XXII. fig. 6.) 
Male. Primaries reddish-grey, from the base to about the middle dark reddish-brown, bordered by a very 
narrow black line which has a few white scales on its outer edge; secondaries reddish-grey, darkest at 
the base and along the inner margin, whitish at the apex: head, thorax, and abdomen reddish-brown ; 
antenns brown. Expanse 14 inch. 
Hab. Costa Rica, Irazu 6000 to 7000 feet (Rogers). 
Only one specimen of this species was sent; it is allied to H. guttularis, from which 
it is easily distinguished by the very different colour of the wings. 
6. Hydrias laronia, sp.n. (Tab. XXII. fig. 7.) 
Male. Primaries pale brown, crossed about the middle by a wide greyish-white band (widest on the inner 
margin, where it extends almost to the anal angle), which is itself crossed by a very narrow white line 
from the costal margin near the apex to about the middle of the inner margin, and near the base by a white 
line, a brown spot at the end of the cell, and a submarginal row of white lunular markings (edged with 
darker colour on the inner side) extending from the apex to the anal angle; secondaries pale brown, 
greyish along the costal margin and near the apex, and with an indistinct white line crossing beyond the 
middle from the costal margin to near the anal angle (but not reaching the anal margin), and a submar- ~ 
ginal band of lunular markings as on the primaries but not so distinct; the underside of both wings. 
uniform pale reddish-brown: head, the front of the thorax, and the antenne pale brown; thorax brown, 
with numerous white hairs; abdomen pale brown, with long greyish hairs at the anus; legs brown, with 
some greyish hairs. Hxpanse 13 inch. 
Hab. Panama, Bugaba (Champion). 
Two males of this beautiful insect were obtained by Mr. Champion; H. laronia is. 
quite unlike any other species of the genus known to me, but comes nearest to an 
undescribed form from Ecuador in my own collection.
