MYCALESIS. By H. Frtxhstoreer. 
it is easy to confound transiens and dexamenus if their up. s. alone are glanced at. Their is no analogy between 
the up. s. of dinon from S. Celebes and transiens because the broad pale yellow subapical sloping band 
so conspicuous in dinon is completely wanting. The h. w. of transiens are too of a pale yellow instead of a blackish 
ground colour. On the other hand the un. s. of transiens harmonises so fully with dinon that it can only be 
distinguished by a difference of small importance, viz. the red brown crescent is separated from the lower eye- 
spot by a yellowish space 4 mm in breadth which in transiens is nearly 4 mm broad. In typical dexamenus the 
distance is still greater and the approach to the eyespot takes a violet (instead of a yellow) tint. Further 
transiens differs from dinon through a darker gloss at costal border of f. av ., through the somewhat broader 
median band and the less sharply zigzagged inner antemarginal line of li. ws. dinon and transiens possess 
common secondary sexual characteristics distinguishing them from dexamenus of N. Celebes. Both have 
a narrow deep black patch of scales near the basis of subcosta h. w. up. s., their distal rests on a bed of yellow¬ 
ish scent hairs which dexamenus does not possess any more than its relation ophthalmicus does, though it is 
found again in haasei Rbr. from Bangkai. The mutability of the scent patches in dexamenus supplements what 
has been already said about malsara, mausonia and annamitica. Here too the salient point is the variableness 
of scent organs within a species and the grounding of possibile modifications on a greograpliic i. e. climatic 
basis. Increase of scent apparatus in droughty *) and decrease of same in damp **) regions. 
M. tilmara (91 f). Groundcolour the pale orange of M. ophthalmicus from the Celebes. The f. w., tilmara. 
like that of dinon, has a broad sloping black apical patch, the proximal between the middle and lower median 
veins is somewhat curved out, approaching within 2 mm of the cell at the apical and suddenly narrowing 
at anal angle under M. 3. Two white pupilled black eyespots on the un. s. are visible by transparence. H. w. 
with two black antemarginal black lines. Base of wings somewhat darker. Un. s.: Fairly uniform red yellow, 
with well marked brown red median bands and a striking pale yellow crescent in the region of lower eyespots 
f. w. Two black and one proximal red brown wavelines. Eyespots as in dexamenus from N. Celebes only some¬ 
what smaller and ringed with paler brown. The red brown median band of h. w. narrower than in dexamenus. 
Ground colour reddish yellow instead of blackish brown and the pale yellow approach to the anal eyespots 
f. w. double as broad and brighter. Scent organs of h. w. similar to those of dexamenus, the scaleless patch 
rather bigger and lighter, the radiate hair pencil pale yellow instead of brown, t/ilmana is rather smaller than 
dexamenus and if intermediate forms be found on the islands between Celebes and Sangir will possibly be 
considered a subspecies of the same. Sangir. 
M. ophthalmicus Westw. (91 e). This species described as “ Messaras ” is, through the secondary sexual ophthalmi- 
characteristics nearly allied to dexamenus and haasei and possesses in common with them a narrow shiny andro- cus - 
conial region on up. s. h. w., covered by a thin scent brush. On f. w. no sexual markings on either side. 
unipupillata Fruhst. is a passage from ophthalmicus to hassei , with similar markings on h. w. un. s. and the 
general light colouring. Talisse Island, Lembeh Island, W. Celebes. 
M. haasei. Same sexual markings as in dexamenus transiens Fruhst. Androconial patch of h. w. up. s. haasei. 
rather narrower. Two vars.: haasei Rbr. Bangkai. Up. s. dark red brown with gray black distal border, which 
L isolated from the darker basal part of both wings by a pale yellow ochre longitudinal belt. Un. s. as in follo- 
Aving form. — unipupillata Fruhst. (91 e). Much paler than haasei, submarginal bands of h. av . un. s. more wavy, unipupil- 
Up. s. of wings shows great similarity with ophthalmicus Westw. Habitat, Tonkean, East Celebes. lata. 
M. deianira Hew. the fourth of the Lohora group from Celebes, f. av . without sexual markings whereby deianira. 
it is easily distinguished from pandaea Hpjj. of the next group. Up. s. like dexamenus reminds one of Clerome 
menado Hew. Ground colour red broAvn, lighter toward extremity of h. w., and changing to a green black near 
apex of f. w. on which is a black median eyespot. Un. s. as in deianirina , but yellowish instead of blackish 
and the antemarginal lines nearer together. 1ST. Celebes, up till uoav only known from Minahassa. 
b. F. av . with black hairpencil on submedian ( Celebina Fruhst., Physcon Nicev.). 
M. pandaea. likewise only taken hitherto in N. Celebes, and, there too, in two local or season forms, pandaea. 
— padaea Hpff. somewhat larger than deianira and minus the black median eyespot up. s. f. av . — deianirina padaea. 
Fruhst. (92 f). Submarginal lines of both wings more deeply Avaved. F. w. darker, h. av . lighter particularly deianirina. 
in anal angle, h. w. un. s. Avitli four instead of three eyespots. Very rare in Toh-Toli, November, December. 
*) S, Celebes with its dry climate, consequently light woods, the trees bein frequently interrupted by stretches 
of prarie. 
**) N. Celebes with its wet climate and real tropical thick forests almost always dripping with rain. In the south 
are the pale and in the north the dark forms.
