The moth appears about the end of June or early July, and has been noted, in good condition, as late as August 17. It seems to be of very local occurrence in England, but some of {2} its known haunts nearest to London are Bromley in Kent, Richmond Park and Norbury in Surrey. At Palmer's Green, Middlesex, a specimen was found on an oak trunk, July 27, 1902, and a female example came to light in West London in 1906. In 1888 it was plentiful at sugar in the Bromley district. The New Forest in Hampshire is a noted locality for the species, but although it may abound there in some years, in other years it is scarce or entirely absent. It is rather more constant in Epping, Romford, and some other of the Essex woodlands, and occurs also in Berkshire, Huntingdonshire, Northamptonshire, Gloucestershire, and Devon. Odd specimens have been recorded from Tarrington, Herefordshire; St. Albans, Hertfordshire; and from Tuddenham, Suffolk. The var. _renago_, and its modifications, has been chiefly obtained in Essex and Huntingdonshire, but it has been found also in the Reading district, and elsewhere. THE LUNAR-SPOTTED PINION (_Calymnia pyralina_). There are two colour forms of this species; var. _corusca_, Esp., is rather brighter in colour than the female specimen shown on Plate 2, Fig. 3, which approaches more nearly the duller coloration of the type as described by Vieweg. The latter is perhaps the least frequent in England generally, but it occurs sparingly in Middlesex. The caterpillar is green, with whitish warts emitting fine hairs, and has three lines along the back, the central one white and stripe-like; a yellow stripe low down along the sides is edged above with black. It feeds in April and May on elm, oak, apple, plum, etc., among the leaves of which it hides by day, and may be dislodged therefrom by jarring the boughs. (Plate 3, Fig. 2, after Hofmann.)

On some nights it will come freely to sugar and on others it seems more partial to honeydew. It is obtained most frequently perhaps in Berkshire, Middlesex, Surrey, and Hampshire, but it is also known to occur in Devon, Dorset, Sussex, Essex, Suffolk, Cambs., Hunts, Hertfordshire, Oxfordshire, Gloucestershire, Herefordshire, and South Wales. A specimen has been taken at a gas lamp in Chester. Abroad, the range extends to Japan. THE LESSER-SPOTTED PINION (_Calymnia affinis_).
