184 THE ENTOMOLOGISL’S RECORD. 
bees’ nests, but rather that it gives them protection from their hosts 
when they arrive there. In the case of the permanent social parasiti¢ 
ant, Aneryates atratulus (1915), as shown by Crawley and myself in our 
experiments when introducing it into nests of its host, Tetramoriun 
caespitum, the Aneryates female seized hold of, and held firmly on to, 
the antenna of a Tetramorinm worker; and as long as the grip was 
maintained, this action appeared to render it safe from the attacks of 
the owners of the nest. As with the ant, the beetle may thus obtain 
the nest ‘‘aura’’ of its hosts. 
The notch in the clypeus of the Antherophagus, so well explained by 
Wheeler, reminds me of the notch in the clypeus of the slave-making 
ant Formica sanguinea. It has also been suggested that this is an 
adaptation to carrying the cocoons captured from the nests of the 
slave species. 
I can add the following facts in connection with Antherophagr 
being found in Humble-bees nests, to those mentioned by Wheeler. 
In 1896 and 1897 Tuck records finding specimens of 4. pallens in 
nests of B. agrorum, B. lapidarius, and B. sylvarum, and A. nigricornis 
in nests of B. latreillellus and B. terrestris, in the Bury district, 
Suffolk. 
In 1898 Bouskell when recording the Gapture of A. niyricornis on 
low parsnip blossoms, ete., in Buddon Wood, Leicestershire, remarks : 
«The fact of the beetle frequenting flowers like the fox-glove, infers a 
desire to be conveyed to the nest jof a Bombus], probably for the 
purpose of oviposition.” 
In 1900 Buckle took specimens of A. niyricornis im a nest of 
B. terrestris in the Foyle district in Iveland. 
In August; 1904, I found a nest of Bombus muscorum near 
Lyndhurst in the New*Forest. The comb was in a hollow in the 
sround and was covered over with bits of cut-up leaves and grass. On 
digging up the nest a specimen of Antherophayus silaceus was found 
in company with a number of Cryptophayus setulosus and a few 
other beetles. 
On August 21st, 1906, I found larvee of Antherophagi in a Bomous 
nest at Kingsclere. ‘These were never recorded. 
In 1909 Dollman and I dug up a nest of Bombus muscorum 
at Sandown, I. of Wight, in which u specimen of A. pallens was found. 
This was on August 15th, 1908, and the actual locality was the foot 
of * Limpet Run.”’ 
Cottam records in 1909 finding A. pallens and its larve in nests of 
B. muscorum in Derbyshire. . 
On August 28th, 1911, Dollman found a large nest of B. hortorum 
situated quite 8 ft. down in w large complex rabbit-burrow, and after 
digging it up with considerable difficulty captured a specimen of 
A. pallens in it. 
In 1920 Scott in-an interesting paper on some inhabitants of a nest 
of B. derhamellus received from Hoo near Rochester in 1918 records 
among other insects, the presence of three Antherophayus larve. Two 
of these he reared which proved to be 4. pallens, and he gives some 
valuable notes and detailed observations on the punation, etc. He 
was unfortunately unaware of Bold’s records, and apparently of 
Wheeler’s 1919 paper; as he credits Perris (1877) with the first 
observation on an Antherophagus clinging to a Bombus, and secondly
