siderable buzz or bum nearly as loud as a Sesia ; 
it twisted about its rather long tail, and turned it up 
like a Staphylinus. I put it under a glass, and placed 
it in the sun ; it became quite furious in its confine- 
ment, and never ceased running about for two hours.” 
** By putting two bees ( Andrena lalialis) under a 
glass in the sun, two Stylops were produced ; the 
bees seemed uneasy, and went up towards them, but 
evidently with caution, as if to fight, and moving 
their antennae towards them retreated; the oddest 
thing was to see the Stylops get on the body of the bee 
and ride about, the latter using every effort to throw 
his rider. A large hole is left in the tail of the bee 
when the Stylops escapes, which closes up after a 
time. I have found five species of Andrenas in- 
fested.” 
Our other two genera are extremely rare ; Elenchus 
tenuicornis has been taken by Mr. Dale near Glan- 
villes Wootton, Dorset, in June (White-down, June 
11th, 1830, and Alder Mead, June 27th, 1839) ; by 
Mr. Walker at Southgate, by Mr. Kirkby in a 
spider’s web in Suffolk, and by Mr. Templeton at 
Belfast. Halictophagus Cnrtisii (in the males of which 
the antennie are beautifully branched) has been 
captured by Mr. Dale near Lulworth Cove, and by 
Sir S. S. Saunders near Folkestone ; for several of 
these particulars I am indebted to the kindness of 
Professor Westwood, who tells me that in Sir S. S 
Saunders’ collection there is no trace of the male ; in 
Halictophagiis the nervures of the wings are much 
more pronounced than in either Stylops or Elenchus.
