548 Dr. H. Eltringham on the 
band broader than in the majority of those from Mada- 
gascar. The most constant difference between the mainland 
and the island forms is the marked projection in the former 
of the h.-w. discal band in area 5. 
Saclava is unlikely to be confused with any other species 
except nemeles, but in the latter the subapical spots are 
coalescent, and the h.-w. discal band is continuous with the 
f.-w. white markings right up to nervule 4 of f.-w., at least 
on the proximal side. The male clasper of saclava is of 
the same type as in the yellow marked Madagascar species, 
though its upper projection is less highly developed. All 
these species are undoubtedly closely related. An interest- 
ing discussion by Prof. Poulton on the forms will be found 
in Proc. Ent. Soc. Lond., 2p. xxxv, L908:

MADAGASCAR. 
metella metella. 
Expanse about 45 mm. Ground-colour dark sepia. Markings 
white. In f.-w. cell a long prominent streak pointed at base, widest 
at cell end, projecting beyond, and again reduced to a point. Ina 
few examples this streak is obsolescent. In most specimens there 
are two small marks just above outer point of cell streak. A small 
inner-marginal spot of variable size in la and 1b. Two large discal 
spots in 2 and 3 notably separated by nervule 3. In 4 two small 
spots, larger ones in 5 and 6, and a very small one in 8. Just distal 
to spots in 2 and 3, and 5 and 6, a white transverse line, variable and 
sometimes obsolescent. A hind-marginal border of two white lines 
variable and generally interrupted in 3. 
H.-w. with a broad white discal band followed by dark interner-
