the present annual returns from some vineyard to enable him to meet 

 the ever increasing cost of living. 



From this material was taken the different samples of the destructive 

 work illustrated in this article, together with the specimens of several 

 life stages of the insect (Fig. 370), which have been described by 

 E. 0. Essig, as follows : 



Larvae. — The matured larvae vary from three fourths to one inch in 

 length and from three tenths to two fifths of an inch in diameter. 



The color is yellow with feet and head dark rich brown and the 

 prothoracic plate light brown. The spiracles are also brown. There 

 are two distinct rows of deep yellow spine areas on the dorsum — four 

 areas to each abdominal segment ; a row on each side of the spiracles ; 

 a row in line with the spiracles and which do not appear to bear 

 spines, and a row just above the legs on the sides. Nearly all of these 

 areas bear a single slightly curved brown spine, though on the dorsum 

 of the pro- and mesothorax there are usually two spines to an area. 

 Similar spines also occur around the bases of the prolegs and on the 

 head, prothorax and tip of the posterior end. 



There are three pairs of true legs, four pairs of prolegs, just back of 

 the middle, and one pair of prolegs at the extreme posterior end. The 

 tips of these' legs are brown. 



Pupae. — The pup^ or chrysalids are rich amber brown throughout 

 in color and average about three fourths of an inch in length. 



Adult. — The average length of the adult moth is three fourths of an 

 inch, the wing expanse being about one and one half inches. The 

 general color is orange and black with a hue of iridescent purple. The 

 head is orange with the bases of the palpi and eyes black — the tips of 

 the palpi being orange. The antennae are dark iridescent purple, be- 

 coming somewhat brownish towards the tips. The thorax is black with 

 orange spots at the bases of the wings, two similar spots on the sides 

 of the prothorax just behind the head, and an orange band across the 

 dorsum, and two orange spots on each side of the metathorax at the 

 bases of the hind wings. The legs are black with light orange mark- 

 ings on the coxae and other joints. The forewings are entirely opaque, 

 covered with brown and orange scales with a pinkish iridescense. The 

 hind wings are transparent with brownish-yellow borders. They are 

 also iridescent. The abdomen is velvety black, appearing purple under 

 certain side lights. There are several inconspicuous and two promi- 

 nent orange bands; the widest being near the middle and the second 

 widest being near the tip. The tuft at the tip is black. 



In Japan this insect is known as the "Budoo-no-teppoo-mushi," mean- 

 ing ''gun worm of the grape." The larvai bore into the canes of the 

 grapevines and are very destructive to viticulture in that country.
