242 BRITISH BUTTERFLIES AND MOTHS 



FAMILY X. BOTYM;. 

 PIONEA FOEFICALIS. THE GARDEN PEBBLE. 



This rather dull-looking, but neatly-marked species, 

 is generally distributed throughout the country, and 

 very plentiful. 



The expansion of the wings is rather more than an 

 inch. The fore-wings are pale whitish-ochreous, clouded 

 with pale brownish ; from the tip of the wing a brown 

 streak runs obliquely to the middle of the inner margin, 

 between it and the brown hind margin is a more slender, 

 less oblique grey streak ; in the centre of the wing are 

 two dark spots, almost united in the form of an hour- 

 glass ; they are preceded and followed by the transverse 

 lines, which are very deeply indented, and run very 

 obliquely towards the inner margin. 



The larva is yellowish-green, with the dorsal and 

 spiracular lines darker green ; the head and incisions of 

 the segments are more yellowish ; it feeds on cabbage, 

 horse-radish, etc., in June and July, and again in the 

 autumn. 



The perfect insect appears in May, and again in 

 August ; we often see it sitting on garden-fences, or 

 outside windows of houses ; it flies freely towards 

 dusk, and comes readily to light.
