THE EUROPEAN PINE-SHOOT MOTH. 7 
repeated infestation of the leading twigs during several consecutive 
seasons producing additional malformations which result in a much 
distorted tree of little commercial value. If the pest becomes more 
abundant, then the trees are transformed by the effect of the injury 
into unsightly crippled bushes with no commercial value. 
DESCRIPTION. 
THE ADULT. 
(PI. II, upper figure.) 
The European pine-shoot moth is a small, gayly colored moth, 
about one-half inch long and measuring about three-fourths of an 
inch across with the wings extended. The head and its appendages 
and the thorax are light orange-yellow, and the abdomen is dark gray. 
The forewings are bright ferruginous orange, suffused with dark 
red, especially toward the tips, and with several irregular, forked 
anastomizing, silvery crosslines and costal striguke; the hindwings 
are dark blackish brown. The legs are whitish, the anterior ones 
reddish in front. 
THE EGG. 
The egg is very small, flat, whitish in color, and is laid singly at 
the base of a bud. Dissection of a female abdomen proves that 
upwards of a hundred eggs are laid by each female ; this is a rather 
greater fecundity than is normal in this group of insects. 
THE LARVA. 
(PI. II, lower figure.) 
The young larva is dark brown with deep black head and thoracic 
shield, the latter divided by a narrow central line. The body of 
the older larva becomes somewhat lighter, but is still much darker 
than the larva of any of our allied native species. The full-grown 
larva is two-thirds of an inch long. 
THE PUPA. 
The pupa is stout, robust, light chestnut brown with darker head 
and back. The wing covers reach to the end of the fourth abdominal 
segment. The abdominal segments are armed with rings of short, 
sharp, blackish-brown spines. 
ALLIED AMERICAN SPECIES. 
There are in this country several indigenous species closely allied 
to Evetria buoliana, and like it confined to pine. Some of these 
already constitute a serious problem and periodically do considerable
