2 THE ENTOMOLOGIST’S RECORD. 
five queens developed in an observation nest of Formica fusca. | Journ. 
Linn. Soc., Zool., 15, 884 (1881) ; Brit. Ants, 308 (1915)] 
Monomorium pharaonis, L.—On May 10th I visited the Reptile 
House at the Zoological Gardens, with the intention of capturing 
larve of this ant for photographic purposes. Many 8% 8 were soon 
observed running along their tracks, carrying what appeared to be 
larve, and were promptly bottled. On reaching home, however, I 
found that very few of the objects carried by the ants were larve. 
They mostly consisted of minute portions of lizard skins, very small 
stones, and other unrecognisable substances. The bits of lizard skins 
probably serve as food, but I am unable to understand to what use the 
ants would put the small stones, and other apparently inedible sub- 
stances. 
Leptothorax nylandert, Férst.—Two $ 3 were developed in my ob- 
servation nest of this species, the first appeared on July 14th, and the 
second on July 25th. The ants in this nest are from colonies taken at 
Yvorne, in Switzerland, on Oetober 10th, 1912, and Claydon, in 
Suffolk, October, 1914. It formerly also contained a colony of L. 
affinis, taken in Switzerland, on October 9th, 1912, but no affinis are 
now present. All these ants amalgamated and became one colony 
[Brit. Ants, 159-160 (1915)!. The two g g were no doubt reared 
from larve introduced with the Claydon colony. 
On July 30th I gave these ants some Myrmica scabrinodis 8 pups 
to act as food. Some were eaten, but a few were allowed to hatch; 
all of them with the exception of one 8 were then dragged about, and 
they died in a few days. One Myrmica 8 however was not molested, 
and it lived in the nest until November 3rd, when it died, apparently 
a natural death. It was a very curious sight to see the enormous 
Myrmica %,in comparison with the little Leptothorax 8 8% , quite at 
home in their nest, walking about and resting with them on their 
brood. 
CamponotiIn®: Donisthorpea fuliginosa, Ltr.—On August 27th a 
fierce battle was witnessed between 8 % of this ant and those of D. 
umbrata at Woking. The ants were all around the foot of a hollow 
birch tree; hundreds of dead wmbrata lay about, many dead winbrata 
were fastened by their mandibles to the legs and antenne of live fult- 
ginosa 8%, and some 8 8 of both lay dead, joined inextricably 
together during their death struggle. A few live wmbrata were still 
fighting with the fuliginosa ; but the colony of the former appeared to 
have been practically exterminated. 
I have already recorded [Hnt. Rec., 27, 207 (1915)| that a D. fuli- 
ginosa @ which had been accepted into a colony of D. wnbrata (and 
mixto-umbrata) on August 11th, 1912, died on August 29th, 1915. All 
the old umbrata 8 8 having died, she had been accepted by a large 
number of fresh wbrata 8 8 from Woking. This left me with a 
queenless wmbrata colony, and having brought home a number of 
virgin fuliginosa 8 8 taken in a fuliginosa nest at Weybridge, I 
removed the wings of one of these on September 8rd, and introduced 
her into the observation nest containing this wnbrata coleny. Sheran 
about among the wmbrata 8 8, tapping them with her antenne, she 
was not attacked and soon gained the last (dark, damp) chamber of the 
nest, which contained the bulk of the wnbrata 8 8. She appeared to
