were many apterous viviparous females, a few nymphe, and one much 
damaged alate female, the antenne unfortunately being absent. In 
spirit they still showed a greenish hue, and I at first took them to be 
the Aphis plantaginis, Schrank, but the marked, short, thick cornicles 
at once separate it. This is the third myrmecophilous Aphid I have 
received from Africa. 
It probably occurs on some native Rhodesian plant just as the 
myrmecophilous Aphis plantaginis of Schrank does in Kurope. 
SCIENTIFIC NOTES AND OBSERVATIONS. 
Tar HouR oF EmerceNce of Lepiporterous Imacines.—It appears 
that very little is actually known about the time of day at which but- 
terflies and moths of any particular species emerge. I can state with 
some confidence that certain species have a definite time of day at 
which they may be expected to appear, but it is quite possible that this 
is not so with all species, and that the emergence of these may be de- 
termined by some totally different factor, such as temperature or 
humidity ; we require a mass of observation on as many species as 
possible, and it is quite impossible for most of us to know the actual 
hour of emergence of most of our bred insects, but I publish these few 
observations in the hope that some great and successful breeder may 
become interested in the matter. 
Melitaea aurinia. See Ent. Rec., xxiii., 1911, p. 26. Both sexes 
appear to emerge early in the afternoon.

—On Saturday, July 31st, I left Waterloo Station for Swanage, arriv- 
ing there that evening, and put up at “ Craigside,”’ a private hotel, 
which I found quite comfortable, but very crowded this year owing to 
the war. My object in visiting Swanage was to obtain an English 
series of Thymelicus acteon, which occurs in various places along the
