432 LYCAENIDA. EOOXYLIDES. 
Genus 165.—EOOXYLIDES, nov. (PLATE XXIX), 
FOREWING, costa considerably arched, slightly indented at the base ; afex rather acute 
in the male, much rounded in the female, outer margin nearly straight, perhaps slightly concave 
in the male, much rounded in the female, iz#er margin straight ; costal nervure extending 
to opposite the apex of the discoidal cell; first sudcostal nervule well separated from the 
costal nervure, second subcostal with its base considerably nearer to the base of the upper 
discoidal than to that of the first subcostal ; middle disco-celludar nervule originating from the 
upper discoidal close to its base, straight, upright, exactly in the same straight line as the 
Zower disco-cellular, the latter a little longer than the middle; second median nervule given 
off some little distance before the lower end of the cell ; sudmedian nervure sinuous. MALE 
with a circular glandular patchiof modified scales on the middle of thedisc, occupying the 
bases of the median interspaces and extending slightly into the cell, bearing itself outwardly 
in the first median interspace a conspicuous silky perfectly round patch of very densely 
packed scales. HINDWING, with three ZazJs, all highly ciliated (“ fluffy ”’), not filiform, the two 
at the ends of the second median nervule and submedian nervure very short, the one at the 
end of the first median nervule very long (about half an inch in length), all the tails traversed 
more than half way to their apices by their respective veins ; costa much arched at base, then 
straight to apex, outer margin increasingly sinuous ; addominal margin deeply excavated 
below the apex of the internal nervure; costal nervure arched at base, then straight to apex, 
which it reaches ; first subcostal nervule gently arched at base ; disco-cellu/ar nervules almost 
in one straight line, slightly outwardly oblique, the upper somewhat shorter than the lower ; 
second median nervule originating at the lower end of the cell; sudmedian nervure straight ; 
internal nervure rather long and sinuous. Antenne short, less than half the length of 
the costa of the forewing, gradually clavate; eyes naked ; Jody short, rather robust. Type, 
the “ Oxylides” tharis of Hiibner. 
Mr. W. Doherty, who has closely studied these butterflies in life, places this genus,’ 
Yasoda, Doherty, MS., and Zoxura, Horsfield, in a subfamily which he names Zoxurine, 
He has given me the following MS. notes on the subject: ‘‘ The Loxurine seem to come’ 
between the Amélypodias and Theclas. Loxura most nearly approaches the former, and Zooxy- 
lides the latter. The egg resembles that of one group of the Amdlypodias, which, however, lacks 
the apical carina. It is also something like those of the first genera of the Zheclas, such. 
as Drupadia, Moore. These differ from the Zoxurine in the absence of the carina, and 
in the great size and depth of the green depressions (which in the Zoxurvine are minute), 
and from the other Zfec/as in the smoothly-rounded white coating, free from tubercles. The 
young larvze of the Loxurineg are somewhat intermediate between those of Drufadia and the 
above-mentioned group of the Amdlypodias, but possess peculiar features of their own.” 
‘© As a group, the Zoxurine are very slow in flight, and not at all timid; they are very 
conspicuous, being bright orange in colouring, though Zooxylides is black above. The

“This species varies very much in size, and is probably somewhat widely distributed. It is allied to the 
Myrina ravindra, Horsfield, a Javan species which belongs to, and is the type of, this genus. We thus find 
D. moovei inhabiting Borneo, Sumatra, and the Malay Peninsula, and differing from a closely-allied Javan 
species, as is so frequently the case in all branches of Malayan Zoology, and has been so well and ably pointed 
out by Mr. Wallace.”’ (Distant, |. c. in Rhop. Malay.) > ; : 
D. moorei, Distant, is very much nearer to D. boisduvalii, Moore, than to D. vavindra, Horsfield ; it 
differs from the former in both sexes on the upperside in having the orange band almost obliterated, reduced 
to a few irrorations only or entirely absent, and on the underside in all the markings being much heavier and 
darker. I have seen numerous specimens of this species from Singapore, Silangor, and North Borneo, kindly sent 
tome by Mr. W. Davison. Mr. Doherty notes (Journ, A. S. B., vol. lviii, pt. 2, p. (1889), that he “‘ cannot find any 
constant difference between Mergui [specimens of D. doisduvalii] and Perak specimens” | [of D. moorez), 
As far as I am able to judge from the material at my disposal, the two species can be distinguished at a glance. 
D. boisduvalii on the upperside of the forewing in both sexes has two-thirds of the surface orange, this colour 
in D. moorei is confined toa very small patch in the middle of the disc, or is entirely absent. A perfect 
gradation between these two extremes may however be hereafter obtained. ‘The differences between Burmese 
specimens of Biduanda thesmia, Hewitson (=8. fabricii, Moore, ) and typical specimens of that species | from 
the Malay Peninsula are almost exactly paralleled in Drupadia boisduvalii and D. moorei, but whereas in the 
former the males from both regions are almost identical, though the females differ considerably, im the latter 
the two sexes are widely different.
