Oct. 17, 1917.—I am only here for a day or two waiting 
for a boat from Lagos to Port Harcourt, from which I go 
up the new line for a bit and then strike east to Okigwi. 
Port Harcourt. 
Nov. 15, 1917.—I believe I have found still another 
facies of the Decatoma-Coryna-Mylabris complex. I won’t 
be able to send them from here as they are not dry yet, but 
I will I hope manage them for the next. [’m afraid they will 
be all I'll be able to send for my Xmas gift, but I couldn't 
get a chance to do better. For most of the time I was 
travelling in country that is rather unsettled, besides being 
entomologically and mycologically rather arid—grass 
country. The treks were long and I had to keep in touch 
with unwilling carriers who were, not without reason, 
afraid to go twenty miles from their own village to the 
next rest camp. At this time of the year in these parts 
and over to the Cross River (that is in the Udi and Okigwi 
districts, east of the Niger, north of here about 100 to 150 
miles) there is a notable head-hunting ju-ju in vogue. I 
believe the hands of the village belles are only given to 
youths who have sufficient enterprise to secure the head of 
some other tribesman. The limits to which “ auri sacra 
fames”’ will push a mortal man are nothing to what Eros 
can do in these parts. The victims do not get a clean, 
straightforward death (nor even a quick stab in the back). 
They are subjected, I believe, to not a little ceremonial 
torture of a very dreadful kind. It is odd to think of this 
happening within ten miles of a railway. But I am getting 
away from my subject. I have got forms like some of 
those at Ibadan (Decatoma, I think), but others with the 
yellow bars on each elytron reduced to two yellow dots, - 
the antennae black with a red tip, otherwise very closely 
resembling the Ibadan forms. I have got one or two others of 
other kinds, but unfortunately none 7m cozté and not a great 
series, for I simply had to snatch at them as I went along 
wherever their food-plant, a Convolvulus, occurred. As 
far as possible, too, one gets as much of one’s trek in before 
the sun gets too hot, and, in early morning, say up to 8 
or 9 o’clock from 5 a.m., they are hard to find. They rather 
like the sun and were not to be found in the heavily shaded 
palm groves. But they may prove to be of interest, and 
some day I may get a better chance to add to them.
