SIR JOHN LUBBOCK ON ANTS, BEES, AND WASPS. 121 
rufescens, Formica sanguinea , F. pressilabris , F. fusca , F. ruji- 
barbis, F. rufa , F. exsect a, Lasius niger, and Tapir oma erraticum, 
appears to agree in its habits with Dinar da, and to devour dead 
and wounded ants, as also do the Myrmedoniae. 
Dr. Wasmaun confirms entirely my observations, in opposition 
to the statements of Lespes, that while ants are deadly enemies 
to those of other nests, even of the same species, the domestic 
animals, on the contrary, may be transferred from one nest to 
another and are not attacked. 
He justly observes that, no doubt, many interesting dis- 
coveries are in store for us as to the relations between ants and 
their guests. The marvellous and grotesque antennae of the 
Paussidae wfill doubtless, one of these days, tell a wonderful story 
to some patient and fortunate observer. 
Mimicry among Ants. 
Prof. C. Emery has published in the Bull, della Soc. Eat. 
Xtaliana, 18S6, a short, but interesting note on the habits of 
Camponotus lateralis. Of this species there are two varieties : 
one black, like its nearest allies ; the other red, with the abdomen 
and part of the thorax black. They live in small colonies, and 
make expeditions up trees to collect honey-dew from the Aphides. 
The black type (C. foveolatus , Mayr, C. ebeninus, Emery) some- 
times goes in troops, but generally a few join the troops of other 
black ants, such as Formica gagates and Camponotus cethiops . 
Prof. Emery suggests that, their numbers being small and their 
sight not very good, they find it convenient to accompany other 
ants which live in larger communities, and that they perhaps 
escape detection from the similarity of colour. 
This suggestion derives some support from the fact that the 
red variety accompanies in a similar manner the troops of 
C remast og aster scutellaris, which is red and black, and at first 
sight curiously like the red variety of C. lateralis. Cremasto- 
gaster scutellaris lives in immense communities among the pine 
woods along the shores of the Mediterranean, and is, as I know 
to my cost, a very pugnacious species. Prof. Emery suggests 
that the black form of C. lateralis is the original type, resem- 
bling as it does its nearest cougeners ; and that the red variety 
has the advantage, from its similarity to Cremastogaster scutel- 
laris. , of using that species as its guide and of sharing, undetected, 
in the produce of its flocks and herds. Prof. Emery observes
