convparative notes on Chilades galba. 203 
is unusually long, inclined forwards, and rather broad; 
the aedoeagus irregular tapering more narrowly at the tip 
with a long orifice. The clasps are copiously furnished 
with bristles, many being very long; the arms of the 
tegumen have them also, but shorter, finer and much less 
plentifully. 
Chilades phiala, Gr. Gr. 
6. Both wings violet blue. Primaries with the termen very 
narrowly brown, secondaries with the termen broadish with the 
marginal row of dark spots moderately distinct. Underside both 
wings creamy grey with the spots edged with white; primaries with 
a spot closing the cell, a series of six more or less confluent spots 
beyond the cell, not so far beyond as in galba, a double series of 
crescent-shaped terminal spots, the outer row being indefinite. 
Secondaries with a series of three black basal spots and one subcostal, 
the latter one being well beyond the middle of the costa and lying 
between veins 7 and 8; there are also two black spots at the anal 
angle edged with metallic blue scales; a spot closes the cell, a series 
of seven irregularly placed spots just beyond the cell, the first below 
and beyond the black subcostal spot, the second shifted well beyond 
the first, its inner white edge being confluent with the outer white 
edge of the first, third inwards, fourth small and shifted inwards, 
fifth further in, sixth slightly out, seventh well in but not detached ; 
a series of four terminal spots which are preceded by a series of de- 
fined, sharply crescentic lunules extending from the anal angle to 
the costa, a very slight suffusion of white in the radial area. All the 
spots in both wings except the five specially mentioned are but 
slightly darker than the ground-colour. 
The genitalia are very closely similar to those of galba; 
the front edge of the clasps instead of being evenly hollowed 
inside the hook is curved outwards. The tegumen is 
slightly longer as to its bifid processes and more hairy ; 
the aedoeagus is decidedly stouter than in galba, though 
of the same shape; a reference to the figures will, however, 
show that it is about one-third broader. 
Comparing the genitalia with those of Chilades lavus 
(Pl. V, figs. 1—3) it will be seen that the clasps have no 
near affinity at all, but that the tegumen is very closely 
allied; in each case the tegumen is highly reduced and 
very highly bifid, consisting of two long thin arms, almost 
as narrow as the falces, ending in a fine point. In laius 
the hairs are long and very fine, the spicules from which
