PANDEMOS.—ARICORIS. 479 
1. Pandemos nymphidioides. (Tab. XLVI. figg. 5, 6.) 
Pandemos nymphidioides, Butl. Cist. Ent. i. p. 79'; Butl. & Druce, P. Z.S. 1874, p. 3547. 
Alis anticis rufescenti-brunneis, maculis intra et infra cellulam saturatioribus, maculis tribus inter ramos 
medianos, posticis (preter basin et angulum analem) pallide ochraceis; subtus sordide albis, anticis extus 
pallide fusco-nebulosis, maculis tribus ad angulum posticarum analem fuscis. 
Hab. Costa Rica (Van Patten } 2). 
The single male specimen described by Mr. Butler is the only one which has yet 
reached us; though its coloration suggests that Nymphidium is the genus in which it 
ought to be included we are in little doubt that it was rightly placed by Mr. Butler in 
Pandemos. We note, however, that the peculiar patches on the wings of P. arcas are 
absent in this species, and it is possible that closer dissection may reveal other 
differences. 
2. Pandemos godmanni. 
Pandemos godmanni, Dewitz, Mitth. Miinch. Ent. Ver. i. p. 90, t. 2. f. 7°. 
Alis anticis apicibus aculeatis, margine externo apicem versus inciso, margine interno arcuato, posticis 
elongatis et rotundatis. Anticis rufo-brunneis, fascia ultra cellulam arcuata a costa fere ad angulum 
analem extendente alba, introrsum pallide lilacinis; posticis violaceis, marginibus fuscis; subtus sordide 
griseis, anticis fascia alba pagine superioris latiore et plaga magna intra eam usque ad basin (preter 
costam) extendente, nigra. 
Hab. Mexico, Vera Cruz (Deppe 3). 
This species is alone known to us from the single male example in the Berlin 
Museum obtained by Deppe at Vera Cruz in Mexico, and described and figured by 
Dr. H. Dewitz in the “ Mittheilungen des Miinchener entomologischen Vereins” in 
1877, and placed by him in the genus Pandemos. Whether it really belongs to this 
genus or not it is impossible to say, as the shape of the wings is abnormal, and the 
figure does not show the projecting palpi ; moreover, the neuration of the front wings 
is evidently not drawn with exactitude. Our description was compiled from Dr. Dewitz’s 
figure. 
ARICORIS. 
Aricoris, Westwood, Gen. Diurn. Lep. p. 449 (1851). 
We are acquainted with fifteen species belonging to this genus, which extends from 
Nicaragua southwards to the Amazons valley and Guiana, two only entering our 
country. 
The subcostal nervure of the primaries in A. jansoni emits two branches before and 
one after the end of the cell; the discocellulars are only partially atrophied, and both 
of them convex; the middle discocellular meets the subcostal at the same point as the 
upper radial, the lower the median a little beyond the second branch; the costal side 
of the cell is a little longer than the median side. The secondaries have a basal nervure ;
