166 SCOPULA OLIVALIS. 



inch in length, and tapers a little at both ends ; the 

 middle segments of the body are rather stout and 

 of plump character, well cut at the divisions, 

 especially on the belly ; the ventral and anal legs are 

 slender; the ground colour of the head and body is a 

 semi-transparent green, sometimes a blackish-green 

 on the back as a dorsal line, but always melting 

 gradually into a paler green on the belly, the skin 

 rather shining; the glossy head is marked just on the 

 crown of each lobe with a short black streak of 

 freckles and more broadly at the sides with two 

 longer streaks of black freckles ; two pairs of minute 

 black dots on the face, the mouth brownish, the 

 antennal papillae tipped with black; the semilunar 

 shining plate on the second segment is of the ground 

 colour, but boldly defined at the sides with black 

 blotchy freckles, also in front and back with black 

 dots ; on the third and fourth segments the glossy 

 black spots form a transverse series, the uppermost 

 roundish-ovate, the next semilunar, the lower group 

 of three roundish, and a small subdorsal spot occurs 

 behind each of these segments ; the black spots on the 

 other segments are conspicuously large, each dorsal 

 front pair of a rounded-ofF squarish form, each hinder 

 pair somewhat transversely oval ; an extra large spot 

 occurs on the front of the thirteenth, the anal flap 

 bearing a few black dots ; along the sides the row of 

 single large spots are of an irregular form, being 

 squarish above and in front, and obliquely hollowed 

 in a concavity behind, wherein occurs the small round 

 black spiracle situated exactly on the whitish tracheal 

 thread, which shows faintly through the skin ; below 

 are two more rows of single roundish-ovate spots, and 

 below them on the belly, on either side of each seg- 

 ment is a group of two or three minute black dots ; 

 the ventral and anal legs are tipped with dark brown 

 hooks ; all the black spots are most minutely wrin- 

 kled, and furnished with a fine hair, while the rest 

 of the skin is plump and smooth.
