restricted in its range to the highlands of Costa Rica and the volcano of Chiriqui. 
Our types came from the latter district; but we have from time to time received a 
good series from the former country, where this would appear to be not uncommon. 
DRUCINA. 
Drucina, Butler, Cist. Ent. i. p. 72 (1872). 
A genus closely allied to Pronophila, of which up to the present time only a single 
species from the highlands of Costa Rica was known. We now add a second species 
from Guatemala. The most obvious distinction between Drucina and Pronophila is 
the elongated pointed subfalcate wings of the former in contrast with the short 
rounded wings of the latter. The palpi of Drucina are even longer than those of 
Pronophila, the terminal joint is directed forwards (not downwards, as stated by 
Mr. Butler) and is longer than in the allied genus, the median joint has shorter hair- 
like scales. In the primaries the middle discocellular nervule is bent close to the origin 
of the lower radial, where it emits a long strong recurrent nervule; the lower discocel- 
lular is bent abruptly nearly to a right angle instead of gradually curved. The antenne 
of Drucina are longer in proportion than those of either Pronophila or Oxeoschistus.

Hab. Costa Rica (Van Patten }?3), Irazu and Rio Sucio (Rogers). 
This remarkable insect was first sent over from Costa Rica by Van Patten, and was 
described by Mr. Butler from specimens in the possession of Mr. Druce, into whose hands 
Van Patten’s entire collection passed. Mr. Rogers subsequently found it in the mountains 
of Irazu, in the same country, and forwarded us several examples in fine condition. 
There is little variation between individuals of this species; but in some the pri- 
maries have six submarginal spots, in others the apical one is wanting. The rufous 
subapical spots of the secondaries, too, are sometimes distinct and sometimes joined to 
the larger patch of the same colour. The latter is the case in all female examples we 
have examined ; but it is not a sexual character. Females, too, have extra spots on the 
primaries, one just beyond the end of the cell, another on the second median branch.
