300 RHOPALOCERA. 
c’. Band of the primaries subparallel to the outer margin. 
ce”. Transverse lines across the end of the cell of the primaries beneath. 
a”. Band common to both wings fulvous. 
8. Adelpha leuceria. (Tab. XXX. figg. 7, 8.) 
Heterochroa leuceria, Druce, Cist. Ent. i. p. 2867. 
Alis supra brunneis, fascia communi marginibus externis subparallela ad costam anticarum bifida fulva ; subtus 
rufescentibus, fascia sicut supra albicante, serie communi macularum submarginalium indistincte albida ; 
anticis maculis cellularibus duabus et una ultra eam cinereis nigro utrinque marginatis, posticis ad basin 
fasciis duabus cinereis intima utrinque extima margine interno tantum nigro marginatis. 
Hab. Guatemaua, Polochic valley (Hague), Sinanja (Champion); Costa Rica, Rio 
Sucio (Logers). 
Mr. Hague supplied us with the types of this pretty species, which were taken in 
the valley of the Polochic!; Mr. Champion has since found it in an adjoining valley. 
It occurs, too, in Costa Rica, where Mr. Rogers captured two specimens. 
It has no near allies that we know of. The tawny band running across both wings 
is a peculiar feature shared only by A. ethelda of Ecuador, a species which differs totally 
from the present one on the underside. 
6". Secondaries above without conspicuous marks. 
9. Adelpha tracta. 
Heterochroa tracta, Butl. Lep. Ex. p. 102, t. 88. f. 6"; Butl. & Druce, P. Z. 8. 1874, p. 3437. 
Alis supra brunneis, anticis fascia lata margini externo parallela venis divisa fulva, extra eam fascia altera 
maculosa indistincta ; posticis fasciis tribus margini externo subparallelibus obsolete fulvidis ; subtus fere 
ut in A. leuceria fascia posticarum angustiore. 
Hab. Costa Rica (Van Patten 1), Rio Sucio (Rogers); Panama, Volcan de Chiriqui 
(Arcé, Champion). 
The first examples of this insect came in Van Patten’s collection from Costa Rica 
and were described by Mr. Butler}. We have since obtained many specimens from 
Mr. Champion taken in Chiriqui, where it appears to be by no means uncommon at an 
elevation of from 3000 to 4000 feet. . 
Mr. Butler’s plate represents the band of the primaries of far too pale a colour; it is, 
in fact, tawny brown, a darker tint than is usual in this genus. 
Like A. leuceria, A. tracta is a very isolated species, but they are perhaps more 
nearly related to each other than to any others in the genus.
