two-thirds of the length of the wing, where it terminates abruptly ; posterior wings dusky.
This moth I found on the salt-marshes near St. Osyth, Essex, on the 8th of July last. It is nearly related to C. griseana, Haworth, and to C. vectisana, Westwood, whence the name I have given to it.
Family. — Yponomeutidæ, Stephens.
Depressaria rotundella, Douglas. (Fig. 8).
Expansion of wings 7 lines. Anterior wings much rounded at the apex, of a luteous yellow tinged* with griseous, having two distinct black dots in the centre about a line apart ; posterior wings dusky : head and thorax luteous.
Of this very distinct species I have two specimens, one taken near Mickleham, the other near Sanderstead, both in September. There is also a specimen in Mr. Bentley's collection.
Anacampsis lophyrella, Douglas. (Fig. 9).
Expansion of wings 5j lines. Anterior wings narrower, ferrugi- nous, each with five black tufts placed, one at the base, one before the middle, two about the middle contiguous to each other and across the wing, and one beyond : there are also several very minute tufts near the apex ; between the first and third tufts the lower edge of the wing is luteous : posterior wings, head, and thorax dusky. Taken at Sanderstead in hedges in July.
Anacampsis instabilella, Douglas. (Fig. 10).
Expansion of the wings 7 lines. Anterior wings luteous or ochra- ceous ; a lighter transverse striga near the apex, a line down the cen- tre and several spots variously placed darker ; posterior wings dusky : head and thorax luteous.
This insect was by no means uncommon on the salt-marshes near St Osyth, Essex, in July, but when they rose from the herbage the wind blew so strongly that it was no easy matter to catch them. It is a species that varies exceedingly both in colour and marking, but none of the varieties approach any hitherto named species.
