By F. W. Fkohawk, F.E.S. 



(Concluded from p. 262.) 



The pupa : — Average length, i in. Dorsal view : the head is 

 stjuare ; the palpi-cases are widely separated, sharply pointed, 

 curving inwards, and are very jaw-like in form ; the thorax 

 is biangular at the base of the wing, much nipped-in round 

 the middle, giving a deep concavity to the wing, which is 

 acutely angulated on the hind margin ; the abdomen is attenuated, 

 and the anal point elongated. Lateral view : the head is beaked 

 in front ; the thorax much swollen, with a central deep rounded 

 keel, and is deeply sunken at the juncture of the abdomen; the 

 dorsal line of the abdomen is curved, the posterior segment is 

 truncated, and the anal point flattened and elongated, measuring 

 iV iw- ; the outline of the lateral surface from near the apex of 

 the antenna to the head is almost straight, the antenna incurving 

 at the apex ; the abdomen has a medio-dorsal series of very small 

 ochreous yellow points, one on each segment, and smaller black 

 points forming super- and sub-spiracular rows ; the sub-dorsal 

 series consists of larger points, especially on the 4th segment, 

 which are large, conical, and sharply pointed ; those on the 1st, 

 2nd and 3rd segments are of brilliant metallic appearance, 

 resembling highly burnished silver, with opaline irradiance ; 

 the first pair are the largest and most compressed ; a streak of 

 brilliant coppery gold ornaments the anterior portion of the 3rd 

 and 4th segments, running from the edge of the segment to the 

 silver point ; the ground colour of normal specimens is a pinkish 

 buff, very delicately reticulated with black, two broad oblique
