lines not only broke up the uniform ground-colour, but 
themselves harmonised with the dry silvery stems of the 
grass. 
The Lymantriid Laelia niobe, Weym. (thompson, Druce), 
—This fine species I reared for the first time from larvae 
found on Damba Island and later on Bugalla Island. At 
the close of my stay on Bugalla I found alarva like those 
previously found, but it pupated while still quite small, and 
to my astonishment the moth was totally different from the 
former imagines. I put the case down, at the time, as one 
of synaposematic resemblance between larvae; but, when I 
examined the specimens at Oxford this summer, I found that 
all the large specimens which I bred first were females, and 
the little, very different, form from the same type of larva was 
a male. So that it seems that Laelia niobe is very markedly 
sexually dimorphic. I suggest that perhaps the female has 
been influenced by the extraordinarily abundant and con- 
spicuous Syntomid moth Meganaclia sippia, Plétz, and that it 
is perhaps synaposematic with it. Descriptions of this, and 
many other new larvae, are in course of preparation. 
Resting attitude of Antheua spurcata, Walk. (Notodontidae).— 
A specimen was found resting on a leaf in full glare of the sun 
at Jinja on Jan. 2, 1911. The glistening yellow fore-wings 
were brought together over the back with their inner margins 
contiguous, but at the posterior end the darker yellow anal 
tuft of the body projected upwards between the hind-margins 
of the wings. The moth was very conspicuous and absolutely 
motionless. 
Zygaenid moth mimicking Acraea quirina, F.—I show a 
specimen of a Zygaenid, Staphylinochrous tenellula, Holland, 
which with its thinly-scaled black-bordered red wings is an 
excellent mimic of Acraea quirina, F., with which it may be 
found in the forest, though I have sometimes seen the moth 
outside the forest flying over open grass land. The general 
appearance of the Acraea is particularly well brought out 
on the wing; the flight of the moth is the steady straight, 
rather laboured flight of many conspicuous moths. 
The following cases illustrative of aposematic and procryptic 
coloration have been recorded in the October number of
