GARDEN NOTES. 217 
wide subject and the (doubtless specific) evolutions appear to 
have received little attention. It may be of interest, therefore, 
to note that on the morning of June 26th, at 8.30 a.m., 
members of this genus were forming a somewhat dense hori- 
zontal column near the west bank of the moat, and four feet to 
the east, on the edge of the sunshine, was a similar column; 
each column was about two and a half feet high, and between 
them individual specimens perpetually darted backwards and 
forwards at great speed, apparently mingling for a few moments 
with each column in turn, and straying away nowhere else. 
How long the dance lasted I failed to note, but similar evolutions 
were in progress at the same spot upon the two following days, 
when the movement seemed to vary in no way. 
4, Liophleus nubilus, Fab.—This appears to be a distinctly 
uncommon species of weevil in my twenty years’ experience in 
Britain, occurring only in May (when I took it at Dover during 
1896) and the first few days of June. In Suffolk it is both rare 
and local; and, although Garneys found three at Beddingfield 
about 1870, Tomlin noticed it at Glemsford in June of 1905, and 
Dr. Sharp tells me it occurs freely at Mildenhall, I have never 
taken it outside my garden. Here it may be annually seen 
sparingly, and on May 15th last we were much diverted by watching 
a perfect beetle consuming a leaf of ivy with its nasal mandibles. 
It held the outer edge of the leaf, like a lepidopterous larva does, 
and, like it, excised the leaf in a semicircular manner, beginning 
at the furthest point its rostrum could reach and gradually 
biting the edge towards its sternum, thence repeating the 
process from the furthest point. Here it is most usually found 
among the garden weed locally known as ‘ground elder,” 
though never far from ivy. 
5. A Non-carnivorous Empid Fly.—I have never noticed 
members of the Empide prey upon aught but perfect insects 
till May 5th, when a female T'achydromia pallidiventris, Mg., 
was seen on the disc of a large bramble-leaf, assiduously sucking 
the surface with its proboscis. The leaf was examined with a 
lens and found to be sparingly covered with minute excreta, 
which was not honey-dew, for no Aphids were present, but which 
had probably been emitted by either Apion vorax, Herbst., 
Batophila rubi, Payk., or an Anthocoris larva, all of which were 
sitting immediately above the leaf in question. 1 was careful to 
note that the Empid carried no prey; it is a common species 
throughout Suffolk, where I have studied its curious mode of 
copulation on the coast, Norfolk, Lincoln, and Wiltshire; Mr. 
Bedwell once bred it from a small (? Braconid) cocoon. 
6. Probable Host of Lissonota femorata, Hlmgr.—Nothing 
has hitherto been ascertained respecting the economy of this 
Pimplid Ichneumon, and it may consequently be worthy of note 
that upon June 29th I saw a female walking over and investi-
