b. Primary wings with a small hyaline spot between the first and second median 
branches; secondaries elongated so as to form a conspicuous tail.

Alis fuscis, anticis nigro transfasciatis, macula hyalina inter ramos medianos primum et secundum, et aliis 
minutis ad angulum apicalem; posticis lineis nigris margini externo plus minusve parallelis notatis ; 
subtus alis ferrugineo-rufis fusco irroratis, anticis lineis irregularibus brunneis transfasciatis, posticis 
quoque similiter notatis et ocellis indistinctis ceruleo pupillatis ornatis. 
Hab. Guatemata, Polochic valley (Hague), Purula (Champion).—CotomBia ; Ecuapor ; 
Perv; Botivia. 
This insect has but little external resemblance to the two preceding species of the 
genus. At first sight it approaches more nearly in its general form and markings to 
some of the members of the genus Timetes. This was remarked by Latreille, who . 
compares it with Cramer’s figure of 7. chiron, and points out its similarity to that 
insect. From Timetes, however, it may readily be distinguished by the presence of a 
small hyaline spot between the first and second median branches of the primaries. 
Its range is somewhat singular, as it inhabits Guatemala, where, however, it is not 
very abundant. Thence southwards to Panama it does not occur; but in this district its 
place appears to be taken by its close ally £. arcei. It reappears in Colombia, south 
of the isthmus, whence it extends as far as Bolivia.

E. dione similis, sed alis obscurioribus et anticis fascia subtriangulari fulva plus minusve margini externo 
parallela distinguenda. 
Hab. Costa Rica (Van Patten*), Rio Sucio (Rogers); PANama, Chiriqui (Arcé 1, Zahn). 
As mentioned under the preceding species, this is a close ally of #. dione. \t differs 
from it in the wings being of a much richer and darker brown colour, and in having 
a broad subtriangular fulvous band towards the outer margin of the primaries. It 
occurs in Costa Rica, and extends southwards to the Isthmus of Panama, appearing 
to replace H. dione in these districts. 
This species was originally described by us from a specimen sent by our collector 
Arcé (after whom we named it) from Chiriqui. 
VANESSA. 
Vanessa, Fabricius, Mag. f. Insectenk. vi. p. 281 (1807) ; Doubleday, Gen. Diurn. Lep. i. p. 198. 
Vanessa is strictly a genus of the northern hemisphere, and only enters our fauna as an 
inhabitant of the subalpine regions of Mexico and Guatemala. Here we find the well-
