lows, and the pale brown P. umbrana may be taken in the New Forest and 

 other southern localities, as may also the very variable P. cristana. 



Were we in a locality where birch grows grows plentifully, we should be 

 pretty sure to see the common Paramesia ferrugana. It has forewings more 

 than twice as long as they are wide, with the tips slightly produced, the 

 costal margin of each wing is arched abruptly at the basal end, and is very 

 slightly concave in the middle portion. In colour they are pale reddish och- 

 reous 3 with darker reticulations and freckles, and there are several small tufts 

 of raised scales on the surface. 



There is another tortrix too we may perhaps find a stray specimen of 

 among the osiers, although it is rather late for it. This is the grey Teras 

 cauclana, some specimens are ochreous, in fact it varies very much, and may 

 be found in all shades of grey and ochreous. 



Suppose we search on these sallows for the larva of Scotosia undulata* It 

 is grey, with a broad whitish spiracular line, and there are two thin lines on 

 the back, of a dirty-white colour. We may, possibly be unable to find one, 

 as, although it occurs in several places, it is far from common. But, see ! 

 we have found a sixteen-legged caterpillar, with protuberances on its back — 

 or rather on the back of the sixth, seventh, and eighth segments. In colour 

 it is grey, with three pale stripes on the sides. It is the larva of the Pebble 

 Prominent moth {hotodonta ziczac). We also find it on poplar. And here 

 is another one with no protuberances on its body, which we may congratulate 

 ourselves on finding for it is a decidedly less common species than the gen- 

 erally distributed Pebble Prominent. It is pale green in colour, and has 

 four interrupted white lines on the back and a yellow one along the spiracles. 

 We recognise it as the caterpillar of Pterostoma palpina. Like ziczac, it 

 feeds on poplar as well as sallow, There is another of the Prominent moth 

 caterpillars to be found at this time of the year. It is the larva of the Cox- 

 comb Prominent [Lophopteryx camelina), and is green in colour, with small 

 red spots in a line with the spiracles, and there are two little red-tipped pro- 

 projections on the last segment. We find it in most places feeding on birch 

 and hazel, as well as other trees. 



Here is a grey, thick-bodied moth, at rest on this post. It has a blackish 

 streak from the base of each forewing along the middle, and several other 

 irregular blackish streaks beyond this. It is evidently the Sprawler moth 

 (Petasia cassinea), and although not a very rare one cannot be considered 

 common. 



We may as well search about the dead leaves, under these sallows, for the 

 pupa of Hadena glauca. It is dark-brown in colour, and has spines on the 

 tip and on each segment. Although it is as well to look for it, I fear we
