it as above (Bull. Soc. Vaud. Se. Nat. xliy. 1908, p. 64). It still 
occurs in the Fern and Palm Houses, and I found it this year in 
the Lily House. See Fig. 6 of the plate. “2 
Prenolepis steinheili, More/, var. minuta, More. Found among 
Palms from British Guiana by H. Green. A native of the Antilles, 
Brachymyrmex patagonicus, Mayr. Numerous in the Orchid 
Houses. 
Monomorium minutum, Mayr. [ discovered this very small species 
on one plant in the Propagating Pits. It has also been taken this 
year in the Fern Pits by J. S. Christie, 
Camponotus (Colobopsis) truncatus, Spinola. (Figs. 1 and 2.) The 
discovery of this species is of considerable interest. J. 8. Christie 
found Cremastogaster scutellaris on some “ virgin” cork in the Fern 
Houses, and bottled, as he thought, four specimens, which were sent 
on tome. One of the four turned ont to be a beetle Formicomus 
pedestris, Rossi! (See Fig. 3.) Though very “ ant-like ” in 
appearance, it is not a very good mimic of the Cremastogaster. 
I went down to try and get more. I was not successful in this, 
but I found another species of ant (the Camponotus) in some 
rk The b 
very large square heads. Prof. Forel tells me that there are man 
mimics among the ants of this genus. Also that Colobopsis itself, 
as well as Camponotus lateralis, are held to be mimics of Cremasto- 
gaster scutellaris. The species is abundant in i 
I also found a Psoccus in some numbers in the cork with the ants 
which Mr. Guermonprez has named for me Lepinotus inguilinus, 
Heyd, and remarks that it is very likely the natural home of this 
species is in the nests of insects. 
Of other Myrmecophiles I may mention that Mr. Bagnall and I 
saw a specimen of the little Orthopteron (Myrmecophila prenolepidis, 
Wasm, ?) among the ants of a colony of Prenolepis longicornis, Ltr., 
in the Propagating Pits, but it escaped, as it can jump very strongly. 
Mr. Cambridge has described a little spider (Fig. 5) (Diblemma 
Donisthorpez, Camb. Proc. Dorset. Nat. Hist. & AF. Club, 1908, 
p. 188) which I discovered with the little ant (Fig. 7) Wasmannia 
auropunctata, Roger, in the Propagating Pits last year. It was a 
new genus and species, and occurred in some numbers with the 
ants, to which it bears a strong superficial resemblance. 
Technomyrmex albipes, Smith. (Fig. 4.) The ergatoid J fe} of this 
ant, mentioned in my last list, have since been described by 
Prof. Forel (Bull. Soc. Vaud. Sc. Nat. 1908, p. 2). I took a O of 
this species in the Palm House, 11, ii. 09, the first I have seen. 
The ordinary ¢ is figured (see plate, Fig. 8, as also the little ant 
(Fig. 9), Strumigenys rogeri, Em., of my last list.
