The Amazons advance, often changing their direction like a dog who is seeking a scent: this is exactly what they are doing, they smell the ground with their antennæ in order to recognise traces of the Formica fusca. In this march the eminently republican instinct of the ants comes out.
Now I was curious to ascertain whether F. sanguinea could distinguish the pupæ of F. fusca, which they habitually make into slaves, from those of the little and furious F. flava, which they rarely capture, and it was evident that they did at once distinguish them: for we have seen that they eagerly and instantly seized the pupæ of F. fusca, whereas they were much terrified when they came across the pupæ, or even the earth from the nest of F. flava, and quickly ran away; but in about a quarter of an hour, shortly after all the little yellow ants had crawled away, they took heart and carried off the pupæ.
The linea fusca, which reaches from the pubes to the navel and occasionally to the ensiform cartilage, is a line of sexual pigmentation sometimes regarded as characteristic of pregnancy, but as Andersen, of Copenhagen, has found by the examination of several hundred children of both sexes, it exists in a slight form in about 75 per cent. of young girls, and in almost as large a proportion of boys.
If it gets beyond the parasite, you should spray in winter with crude oil emulsion. If some scales are punctured or have a black spot on top, the comys fusca is busy and you probably will be safe enough without doing anything. Fumigating for Black Scale. I would like to know the best method of eradicating the black scale from my orange trees, whether by spraying or fumigation?
If a colony of the slave-making ants is changing the nest, a matter which is left to the discretion of the slaves, the latter carry their mistresses to their new home. If now I covered over one small part of the nest, after a while some ant discovered it. This I think says much for their public spirit, but it seems to prove that, in F. fusca at least, the powers of communication are but limited.
The Polyergus avoid introducing into their houses adults who would not become reconciled to the loss of liberty, and would prefer to die rather than work for others. They carry off the larvæ of Formica fusca and Formica cunicularia.
I then dug up a small parcel of the pupae of F. fusca from another nest, and put them down on a bare spot near the place of combat; they were eagerly seized, and carried off by the tyrants, who perhaps fancied that, after all, they had been victorious in their late combat.

While this effect is very common, it produces no appreciable injury and needs no treatment for its control. Scale on Apricots. I would like to know how to check the scale on apricot trees. The most common scale on apricots, the brown apricot scale, is usually held in check by the comys fusca, which is as widely distributed as the scale itself.
One is extremely abundant on the pampas, the Mygale fusca, a veritable monster, covered with dark brown hair, and called in the vernacular aranea peluda hairy spider. In the hot month of December these spiders take to roaming about on the open plain, and are then everywhere seen travelling in a straight line with a slow even pace.
