214 Mr. T. Vernon Wollaston on 
been conveyed, it will immediately strike every naturalist 
as probable. And since it is further certain that ants 
are emphatically a wandering race, and would themselves 
rapidly disseminate their small Coleopterous attendants, 
we have everything that is necessary in order to account 
for the co-dispersion of the two.* 
Having stated thus much on this particular subject, I 
will not at present add more, for my object was merely 
to call attention to the two suggestive papers of Mr. 
Murray and Mr. Wallace, rather than to discuss the 
general question itself. I will therefore proceed with 
the minutie of this memoir, taking the several species 
seriatim, in the order which is indicated in my ‘ Coleop- 
tera Atlantidum.’

According to MM. Fairmaire and Coquerel (Ann. de 
la Soc. Ent. de France, 17; 1866), this noble Brachinid 
is in all probability a geographical variety of Dejean’s 
P. africanus. ‘Il parait difficile,” they add, ‘‘de ne pas 
regarder cet insecte comme une simple vari¢té géogra- 
phique du africanus. Quand on compare les individus 
provenant d’Andalousie et ceux du Sénégal on trouve 
cvidemment une grande différance; mais cette différence 
est bien peu de chose si l’on prend pour terme de com- 
paraison les Brachines de Tanger. II est du reste facile 
de comprendre qu’aprés la séparation de Espagne et de 
P Afrique, la race de Brachines restée en Hurope ne pou- 
vant se retromper par un croisement continuel avec celle 
des régions tropicales, a di diminuer de taille et finir par 
constituer un type inférieur au type primitif, comme on 
le voit pour les Carabus rugosus et beticus, et comme 
nous le verrons plus loin pour un Paussus.” 
* During our visit to 8. Iago, of the Cape Verdes, I detected the nearly- 
blind Cossyphodes Wollastont amongst vegetable detritus, at San Do- 
mingos, which had accumulated in the hollows of ancient trees, high up 
above the ground,—situations into which it must without doubt have been 
dragged by the Ecophthora, which positively swarmed.
