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. — Yponomeutid^e, 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.
