much flattened. The head is shining black, and while at rest it 

 is completely withdrawn under the large overlapping anterior 

 segment ; it is only protruded while feeding, and partially so 

 when crawling ; during its progress the head is kept in incessant 

 motion waving from side to side. The colour of the bod}^ is pale 

 ochreous, with medio-dorsal, subdorsal, and lateral dark chocolate- 

 brown longitudinal lines, each being bordered by a whitish buff 

 line ; the whole surface is sprinkled with dark brown warty discs, 

 flattened and semitransparent on their summits ; there are also 

 longitudinal rows of greyish green short tubercles, each emitting 

 a curved whitish hair. The legs are black, and the claspers 

 ochreous; on the anterior segment is a dark purplish brown 

 dorsal blotch. The stamens and petals of the flowers still form 

 their only food, some of the blossoms having the petals thickly 

 perforated by them. The larva is extremely sluggish in its 

 movements. 



On June 1st, I carefully examined all the larvae I had feeding, 

 and found them in various stages, and varying from one-tenth to 

 three-twelfths of an inch in length ; two were in their second skin, 

 about half had moulted twice, and the remainder had moulted for 

 the third time. They all very closely resembled each other in their 

 different stages, but after the third moult the colouring is more 

 vivid. After the second moult it is precisely similar to its pre- 

 vious stage, excepting the advanced growth, measuring one-sixth 

 of an inch in length. After the third moult it is a quarter of an 

 inch long. Colour pale greyish green, with a dark chocolate- 

 brown medio-dorsal stripe bordered on either side by a white line 

 and a double grey-green (darker than the ground colour) sub- 

 dorsal stripe composed of two slightly oblique marks on each 

 segment, each bordered above by whitish ; a lateral dilated white 

 stripe bordered below by an olive band ; the under surface is 

 grey-green. The head is small, intensely black and shining; 

 the large compressed anterior segment has a conspicuous 

 chocolate-brown patch in the centre. The body is clothed in 

 exceedingly fine short hairs ; those on the dorsal area are the 

 longest, and curve backwards. They still continued feeding upon 

 the blossoms. 



During the first week of June a few moulted for the fourth 

 and last time, and the first became full-grown about June 20th. 

 When full-grown it measures while at rest half an inch in 

 length ; the anterior segment is projected, flattened and rounded 

 in front, completely concealing the head ; from the second to 

 ninth segments (both inclusive) the back is considerably elevated, 

 and the segments of uniform size, their sides are flat and sloping 

 to the lateral dilated ridge, the second segment rising abruptly 

 above the first ; the last three posterior segments are flattened, 

 especially the last, which terminates in a broad rounded flap much 

 compressed, similar to the first segment; the eleventh segment is
