fasciatipennis,* or of the Philippine tiger-beetle Tricondyla, by 
the cricket Condylodeira,+ are absolute marvels of deception 
all belonging to that special phase of mimicry where the 
obvious advantage to the unarmed mimic lies in being mis- 
taken for the armed and formidable model. 
As the Lepidoptera are at present the only order in which 
a very considerable number of mimetic relations have been 
observed, it may be of service to note here the various direc- 
tions in which mimicry ramifies within the ordinal limits. 
The very large majority consists of cases where (a) Rhopalo- 
cera are copied by other Rhopalocera ; and, taking the groups 
in succession, we find that (1) Danaine (including Neotro- 
pine) are mimicked by members of their own subfamily, by 
Satyrine, Heliconiine, Nymphaline, Erycinide, Pierine, and 
Papilionine ; (2) a few Morphine by Papilionine; (8) Helt- 
contine by Pierine ; (4) Acrainw by Nymphaline, Lycenide, 
Pierine, and Papilionine ; (5) some Nymphalinw by members 
of their own subfamily ; (6) Pierine by species of their own 
subfamily, and very rarely by Satyrine ¢; and (7) Papilionine 
by members of their own subfamily and by certain Pierine. 
The next series is composed of those comparatively few 
instances where (b) Rhopalocera are imitated by Heterocera ; 
and here it is found that (1) Danaine (true, and Neotropine) 
are mimicked by Castniide, Chalcosiide (three different 
genera), Arctiide (two different genera), Dioptide (three 
different genera), and Geometre (two different genera); (2) a 
few Acraine by Melameride (two different genera); (3) 
Papilionine by Castniide, Chalcosiide, and Arctiide.|| Much 
* See Pryer, Trans. Ent. Soc., 1885, p. 369, pl. x., who in the same place 
also figures another most striking case from Borneo, in which the hymeno- 
pterous Triscolia patricialis is mimicked by the lepidopterous Scoliomima 
insignis.

t In the Oriental region Delias is mimicked by Prioneris and Pieris, and 
in the Ethiopian region Mylothris by Pieris and Hronia. An interesting 
case in support of the probable distastefulness of Mylothris is found in 
Madagascar, where the abundant M. phileris is mimicked by the very scarce 
Elymnias masoura, a Satyrine which is extremely divergent in colouring 
from all known members of its genus and subfamily. 
|| Col. Swinhoe informs me that the Pierine Teracolus limbatus—‘‘ the 
southern form of 7’, etvida "—is accurately mimicked by the Geometrid moth, 
Abravas etridoides. This ease seems to support Col. Swinhoe’s opinion
