228 FOREST ENTOMOLOGY. 



which are switched or clipped annually. The rosette is not con- 

 spicuous until the larva is nearly full fed. It is of dirty-green colour, 

 with black head and shield. 



The pupa is about 4 linos long, of a rich brown colour, and slightly 

 shining. 



The imago appears about the end of June or beginning of July. 

 The fore wings are of a dark smoky-grey colour. The hind wings are 

 of a light -green colour. Eyes intense brown, and with a velvety 

 appearance. Antennse dull brown. Abdomen shining grey colour. 

 Length about 6 to 7 lines. 



This species cannot be regarded as very injurious, yet it does a con- 

 siderable amount of damage to the surface of the hedge, inasmuch as, 

 being often numerically strong, it appreciably affects the growth of the 

 shoots. As the surface is the all-important point in an ornamental 

 hedge, it would often be well to check this pest by simply cutting or 

 nipping off the tender shoots while they contain the larva3, and either 

 burning or throwing them into a bucket containing paraffin. This 

 operation, though rather tedious, would have the effect of reducing 

 the number of perfect insects, and therefore diminishing the attack 

 for the following year. 



Stigmonota regiana (Zeller). 



If the loose projecting bark on very old sycamore - trees be 

 lifted up during the winter months, small cocoons, sometimes 

 quite a number together, may be recognised. In each cocoon 

 there is a small larva, of a dirty - white colour, and about 4 or 5 

 lines long. 



The pupa is about 31 li'^es long, and of a light-amber colour. 



The imago, which appears in June or July, is about 6 or 7 lines in 

 expanse of wings, and when unfolded is certainly very pretty. The 

 prevailing colour of the fore wings is chocolate, whilst on each wing 

 there is a semicircular patch of yellow, which, when the wings are 

 closed, forms a lieautiful circle in the middle of the folded wings. 

 The effect of this marking is somewhat lost when the wings are 

 spread out. 



This species cannot on any account be considered injurious. It is 

 quite possible, however, that the action of the larva? causes the old 

 bark to fall off sooner than it otherwise would do.
