Description of the Larva of Triphcsna interjecta. — It rests 

 in a straight position on the stems of its food plant, and 

 M'hen shaken or annoyed it falls to the ground rolled in a 

 ring, but very soon resnraes the straight position and crawls 

 with rapidity : the head is narrower than the second segment, 

 into which it is partially received; it is porrected, flat, rather 

 glabrous, and not notched on the crown ; the body is obese, 

 rather velvety, the divisions of the segments strongly marked ; 

 it is somewhat attenuated at the anterior extremity, and has 

 the twelfth segment dorsally slightly swollen. The prevailing 

 colour of both head and body is putty-colour ; the head has 

 two dark brown marks down the face, and outside of each of 

 these is a pale mark ; the body has a narrow medio-dorsal 

 white stripe, bordered on each side by brown slightly darker 

 than the ground colour ; near the raedio-dorsal on each side 

 is another narrow white stripe similarly bordered, and differ- 

 ing only in being somewhat less distinct; on each side in the 

 region of the spiracles, but just above them, is a broader and 

 triple stripe, the outer portion on each side being whitish, the 

 middle reddish ; and this compound stripe is also bordered 

 with brown, particularly on its upper margin ; the dorsal area 

 is ornamented with a number of intensely black dots ; on 

 the second segment these are very minute and apparently 

 without much arrangement; on the third they form a straight 

 transverse series and are eight in number ; on the fourth they 

 also form a straight series and are six in number; on the 

 following segments, the fifth to the eleventh both inclusive, 

 they are also six in number on each segment, but no longer 

 form a straight series ; two near the anterior margin of the 

 segment are larger than the rest, the next on each side stands 

 back about the middle on the dorsal area of the segments, 

 and the third on each side is nearer the anterior margin ; 

 the twelfth segment has four of these black dots arranged in 

 a perfect square ; the ventral is slightly darker than the 

 dorsal area, and has a double series of black dots below the 

 compound lateral stripe. The legs are pale, semitransparent
