{111} The moth is out in July, and specimens have been bred in September from eggs laid in July of the same year. To obtain this species, a journey will have to be made to one or other of its special haunts in Kent, lying between Greenhithe and Sheerness. Other localities from which it has been recorded are Kingsdown, Dover, Folkestone (Kent); Brighton, Lewes, West Horsham (Sussex); Isle of Portland (Dorset); Rame Head, Torquay (Devon); and single specimens have been reported from Stowmarket and Felixstowe (Suffolk). THE RUSTY WAVE (_Acidalia_ (_Ptychopoda_) _herbariata_). In _The Entomologists Annual_ for 1856, two species of _Acidalia_ were brought forward as new to the British list. One of these has been referred to under _A. contiguaria_, the other was the present species, which at the time was wrongly referred to _circuitaria_, Hubner. The specimens depicted on Plate 45, Figs. 7 and 10, are of continental origin. Although other specimens were then known to exist in at least two British collections, the first recorded example was that mentioned above. This was captured in Bloomsbury Street, {112} London. In June, 1868, three or four examples were found in a herbalist's shop in Holborn; one occurred on a shop window in Oxford Street in 1873; one example was taken from a door-post in Cannon Street, July 21, 1879; and two others have been noted from the same street, but dates were not given. The latest record, that of a specimen on July 21, 1898, in a shop in Southampton Row, Bloomsbury, closes the list; it then appears that all the British specimens known to us have been taken in London. The eggs are laid on dry or withered plants, upon which the long brownish or greenish caterpillars feed throughout the autumn, winter, and following spring. They pupate towards mid-May, and the moths appear in June and July. According to Guenee, caterpillars seem to have been found only in herb or drug stores, and the moths occur in gardens and houses in July and August. THE SMALL DUSTY WAVE (_Acidalia_ (_Ptychopoda_) _virgularia_).
