on the Bionomics of Southern Nigerian Insects. 409 
of the segments. It was not on its food-plant, and I think 
I will have to kill it without knowing what it is. Finally, 
my boy brought me a curiosity. It looked like an ant 
(a black one about the size of a Camponotus (Orthonoto- 
myrmex) sericeus F.) in the act of engulfing, in a thoroughly 
un-ant-like way, a green caterpillar. “ What on earth is 
this, Joe?” I asked. Said he, “I think some ant ketch 
“um.” ThenI found it was all one animal. I remembered a 
picture in Shelford [lowest fig. on pl. xvi, facing p. 230 
of “A Naturalist in Borneo”’], and to-day I found in 
Lefroy’s “Indian Insect Life,’ p. 472, a picture of a 
Notodontid larva [Stawropus alternus| which, I think, 
must be of the same genus. Looked at closely, of course, 
it isn’t a bit like an ant, but more than likely it is the 
first impression that is the saving impression. The enemy 
in nature is not going round with a Zeiss pocket lens 
magnifying so many diameters. 
6. Hreunetia fulgida Warr. : Geometridae, Boarmunae.— 
[Mr. L. B. Prout considers that Warren’s flava and curvifera 
are synonyms and his own orientalis a geographical race 
of fulgida. A single male was captured, attracted to a 
lamp, July 12, 1918. Farquharson noted that, in the 
resting position, the wings are held upright over the 
back, as in many Geometers. Farquharson was_ here 
doubtless referring to the brief rests between the flights 
—not to the position assumed in prolonged rest. This 
moth is an interesting addition to the great group mimetic 
of Lycid beetles (Trans. Ent. Soc., 1902, pp. 515-18; Proc., 
1918, pp. exxxvuli-exli.) | 
7. Parasa viridissima Holl. : Iimacodidae.—{'Two moths 
bred Dec. 19 and 20, 1917, from larvae feeding on Coconut 
Palm at Awka, 22 miles E. of Onitsha.] 
8. Margaronia prasinophila Hmpsn. : Pyralidae, Pyraus- 
tinae.—{ The following note by Farquharson, together with 
the ¢ Pyrale (both numbered 477), was sent to me by 
W. A. Lamborn. | 
Feb. 4, 1914.—On entering my house the other day, 
Jan. 29, 1914, I observed a pale green Pyralid moth on the 
wall of my room. This was about mid-day, and the moth 
was in a position of rest. On my approaching for a nearer 
view the moth moved slightly, evidently in alarm, though 
without attempting to take to flight. At the same time, 
too, from its posterior end a tuft of dark hairs was exserted, 
and the tip of the abdomen rotated rhythmically from side 
to side, the hairs remaining extruded all the while.
