EBULEA VERBASCALIS. 143 



over the body; at the age of twenty-five days, its 

 length is from three-eighths to nearly half-an-inch, 

 when the pale head is more distinctly freckled with 

 brown, the green stripe on the back and broad band 

 of the sides are brighter, darker, and broader than 

 before, the two white stripes of the back appear more 

 purely white, and a whitish spiracular line is seen 

 extending from the third segment to the side of the 

 anal legs, while beside the black dots, previously 

 noticeable, one on either side of the third and fourth 

 segments is now conspicuously larger than the others. 

 The fall-grown larva measures from six-eighths to 

 seven-eighths of an inch in length, tapering at each 

 end, the segments well divided, and beyond the fourth 

 each is sub-divided by a deep transverse wrinkle on 

 the back into two nearly equal portions ; on the belly 

 they are more deeply divided and very plump ; the 

 ventral and anal legs are slender, the anal pair 

 extended behind in line with the body. In colour the 

 head is of a pale watery drab, finely dotted on the 

 crown with black, and freckled with brown on the 

 sides of the lobes, and a pair of blackish dots are a 

 little above the mouth ; the second segment has much 

 the same pale ground colour as the head, and is also 

 freckled with light brown on the side, where there is 

 a conspicuous black elongated dot, and on the dorsal 

 region is broadly marked, somewhat triangularly, 

 with rich semi-translucent full green, which continues 

 from thence as a broadish dorsal stripe of equal 

 breadth as far as the eleventh segment, from whence 

 it becomes gradually narrower to the thirteenth, having 

 within it a darker pulsating vessel; this green stripe 

 is bordered on either side by a rather narrower stripe 

 of opaque-whitish, with its outer edge a little ragged 

 and slightly melting into the rich translucent full 

 green of the sides, inclining a little in part to bluish- 

 green ; this is again relieved by the spiracular stripe 

 of yellowish-white extending to the anal legs, having 

 throughout its course along each segment a straight
