EUPLOEA. By H. Fruhstorfer.

E. tristis Btlr ., a miniature form of the preceding, forewing similarly marked, but the submarginal tristis. 
ovals of the hindwing removed further proximad, narrower, under surface more copiously dotted with violet 
than palla , forewing with white, partly absent submarginal spots, but both wings with violet cell-patch and 
a row of five transcellular spots. New Hebrides, apparently rare. — scylla sub.sp. hod. is a race without sub- scylla. 
marginal punctiform spots on the underside of the forewing, and with only three distinct subapical white 
spots on the upperside. New Hebrides without more exact locality. 
E. jacobseni Bob. (= wetterensis Frnhst. , baudiniana Godt. ? ?) ('82 e) is a pretty species, which jacobseni. 
inhabits Micromalayana (Timor Group) and-must be regarded as the smallest Stictoploea known, cf: forewing 
with slight violet sheen on a dark ground, hindwing light brown like the upperside of both wings in the 
??. Forewing with very broad, pure white subapical patches, proximally slightly tinged with violet, and four 
prominent rounded submarginal spots. Hindwing with three rounded subapical punctiform spots. A form . 
which probably belongs to the dry season is crassimaculata form, nov., with very broad yellowish white sub- maculatn. 
marginal band on the hindwing in both sexes, recalling orope and fabricia. Wetter. — timora Frnlist.. cf: timora. 
ground-colour of the forewing a very dark, of the hindwing a somewhat lighter brown. From the apex to 
the anal angle runs a row of large white spots, which are proximally bordered with violet. The three upper- 
spots are placed close together, the others being smaller and isolated. The yellowish white submarginal spots 
of the hindwing, as in Sylvester , are distallv separated by a brown tooth projecting from the distal border, and 
are proximally somewhat incised, especially in the ?. Both wings are bordered by a marginal row of white 
dots. Above the end of the cell the cf bears one violet dot, the ? three white ones at the costal margin. 
Of the two silky, very narrow sexual stripes the upper one is 1 / 3 shorter than the lower and both are much 
smaller than in Sylvester. The brown ground of the under surface, which gradually becomes lighter from the 
base to the distal margin, recalls orope Bdv. and oropina Bob.; a colouring which combined with abundant 
white bands lends to the Euploeas of the small Sunda Islands a characteristic stamp. On the under surface 
of timora all the markings of the upperside are reproduced, and in the middle of the wing there is further 
a row of blue-white dots. On the forewing 4 of these spots are costal, 1 cellular, 3 circumcellular, and 1 
or 2 placed below the submedian; the hindwing bears 1 cellular and 6 circumcellular dots. One dot is 
placed at the base of the forewing and 4 at that of the hindwing. Antennae and abdomen as in Sylvester. 
Length of the forewing: cf 41 nnn., ? 34 mm. Timor. 
E. pelor Dbl., an extremely rare species described from Australia, but never found there again. As I pelor. 
have a cf before me from Babber, the Timor-Laut Group is pretty certainly the true locality of the species. 
Upper surface, except for the two sexual stripes, exactly as in sacerdos (84 cl), only with two spots instead 
of a costal patch on the forewing. Under surface as above, but with four transcellular and three discal 
small violet spots on the forewing and a cell-dot and six small blue-violet discal spots on the hindwing. 
Ground-colour deep black. 
E. rogeri Him. is an allied species, likewise very rare, which differs from pelor in the smaller white rogeri. 
submarginal spots on both wings. Locality unknown, probably islands of the Timor or Timor-Laut Group. 
E. Sylvester F. (= dardanus Misk.) resembles eiehhorni Stgr. (81 c) except for the two scent-stripes. Sylvester. 
Under surface exactly as in pelor. — As crithon Misk. a form has been described of which it is doubtful crithon. 
whether it is an accidental aberration of Sylvester or must be regarded as a distinct but very rare species. 
Upper surface deep black with purple sheen and two sexual spots, under surface dark brown with lighter margins. 
Forewing beneath with two blue-white, hindwing with five violet punctiform spots. Like Sylvester at Cape 
York, North Australia. 
Group Trepsichrois. 
Larva with four pairs of very long appendages. Cell of the forewing as in Crastia. Hindwing with large androconia- 
patch and a small spot covered with yellow, shaggy, clubbed scent-scales with short cilia. Anal pencil somewhat shorter 
than in Stictoploea , longer than in Crastia, light canary-yellow, simple, can be easily and strongly moved and projected. 
Valve not examined as yet. The group does not extend eastward beyond Celebes, and hence is purely Indo-Malayan, only 
one species fmulciber) has been observed in New Guinea, as an accidental importation. Of all the Euploeids the species of 
this group all have in both sexes a smell most repulsive for human organs. 
E. mulciber is better known under the designation midamus L. and as such also figured vol 1, pi. 
28 e and described with larva and pupa p. 78. The species belongs to the characteristic butterflies of India, 
but strange to say is wanting in Ceylon and the Andamans, though it is met with again on the Nicobars as 
an occasional migrant. Northwards it extends to Formosa, eastwards to the island of Bali, and is broken up 
into a series of local races, some of them highly specialized. It is further worthy of note that there is a 
series of butterflies and of Chalcosiids which have a convergent garb and afford striking examples of mimicry. 
Even specimens of the Nymphalid genus Penthema and some Papilios of the paradoxus- group, which are much 
larger than the model, resemble mulciber on the wing to such a degree that they deceived me over and over 
again, and my Annamites and Japanese could not distinguish them at all. — barsine Fruhst. is the largest barsine.
