P. 67. Pompritus ExaLTatus. The red-legged variety 
at Turnham Green, Middlesex; Green Street Green and 
Birchwood, Kent-——both sexes. I am strongly inclined to 
consider this variety a good species; for now that I possess 
a series, I can observe some difference of structure. I 
therefore propose the name of aGixis for it—it varies in 
size from 2$—33? lines—a small specimen of the ¢ has the 
third submarginal cell petiolated on both sides. 
P. 68. Pomprtus FascIATELLUS. In Battersea Fields 
and Hackney Marshes; but nothing has yet occurred 
which with any probability may be considered its ¢. 
P. 70. CEROPALES VARIEGATA: On Parley Heath, in 
the autumn of last year (1835), the Rev. G. T. Rudd con- 
firmed Dr. Leach’s previous capture, by taking a single 
specimen of each of the sexes. The g agrees with the 
2 in colouring, and is smaller in size. 
P.81. Muscus campestris. Mr. Curtis has figured 
this species as an Ammophila, and divides it only section- 
ally from that genus; but I see no reason for altering my 
opinion as to the value of its generic separation. I have 
not yet discovered a true Ammophila with the cell petio- 
lated, and I have captured many hundreds for the pur- 
pose of ascertaining, and I possess also an extensive series 
of foreign specimens, both European and exotic, in which 
this formation never occurs; and, besides, the WZ. campestris 
has never yet been found with the wing not petiolated. 
Mr. Curtis’s figure is at folio 604 of his beautiful work. 
Early in the year abundant at Blackwater in Hampshire. 
P. 83. Mr. Stephens informs me that the Sphex flavi-
