THE MEDITERRANEAN NATURALIST 
151 
At Malaga, I have taken several specimens of 
a Catopomorphm with A. barbara , and also found 
a single specimen of this beetle on the summit 
of the Djebel Mousa (Ape’s Hill), Morocco, at an 
elevation of over 2800 feet but the species appa- 
rently does not occur either at Gibraltar or 
Tangier. 
Besides an occasional straggler of Merophysia 
carinulata, Mots., the populous colonies of the 
big-headed, pale testaceous P he i dole megacephala , 
F., appear to give shelter to but one species of 
Goleoptera , the extraordinary Paussus Favieri , 
Fairm. This beetle was found very soon after 
my arrival at Gibraltar, and in some localities 
(near Campamento for instance) it may be called 
abundant, as I have taken as many as twenty 
specimens from a single nest; it appears to be 
found equally on sandy or clayey soils. There is 
much in its general aspect which recalls that of 
Claviger on an enlarged scale, but it is an even 
more sluggish creature, being found motionless 
where the ants are most densely clustered, to them; 
though, as far as I can ascertain 4 it preys on the 
“brood” of the ants like th eSternocceli. Indeed, I 
have never observed, with these southern ants, 
anything at all resembling the solicitude shown 
towards their Coleopterous inmates, as is exhibited 
by our species towards Atemeles and Claviger , for 
instance. The Poussus is found at Tangier, but 
is not so abundant there as at Gibraltar. 
This exhausts the list of Myrmecophilous beetles 
which I have observed in the region of the Straits 
of Gibraltar; and the other ants appear to have no 
guests but the common Mefophgsia , with the 
exception of the rare and singular Anochetus Ghi- 
liariii , Spin., whose small colonies seem usually to 
be quite free from beetles. On one occasion, how- 
ever, at Tangier (December 9th, 18S7), I found 
Pseudotrechus, Oochrotus , Goluocera , Merophysia , 
and Medon seminiger , Fairm., all out for a walk 
together in the warm sunshine, on the top of a 
stone, which covered an unusually large nest of 
this ant. 
My best thanks are due to Mr. Geo. Lewis for 
the determination of the Bisteridoe, and to Dr. 
Sharp for that of the remaining Goleoptera, also 
to Mr. Edward Saunders for the names of the 
ants mentioned in this article.
