TROCHILIUM ICHNEUMONIFORME. 47 



overlapping tendency, and the three hinder ones 

 tapered gradually. 



The head was pale brownish-flesh colour, with three 

 broad stripes of brown down each lobe and with a 

 triangular brown patch between them ; the mouth was 

 blackish-brown. 



The second segment had a semi-transparent polished 

 plate of flesh colour, through which could be faintly 

 seen the back parts of the head slightly tinged with 

 brown. All the other segments were of a uniform 

 pale yellowish-flesh colour, rather opaque, with a slight 

 trace visible here and there of a darker dorsal vessel. 

 The tubercles were not raised, but the situation of 

 each of them was indicated by a very fine pale brown 

 hair. The spiracles were flesh coloured, outlined with 

 brown ; the prolegs the same as the body ; the anterior 

 legs pale brown. 



The pupa was about three-eighths of an inch long 

 and rather flattened beneath, arched upwards rather 

 suddenly from the sharp beaked point at the head, and 

 rounded on the back. The abdomen at its junction with 

 the thorax was depressed at the sides, it gradually 

 widened for about half its length, and then tapered 

 towards the anal extremity, which was rather trun- 

 cated. The abdominal rings had a series of minute 

 covered hooks at their edges. The wing- and antenna- 

 cases were remarkably long, extending nearly to the 

 end of the abdomen. The eyes were black, large, 

 and projecting ; all the other parts were of a shining 

 bronzy-brown. (W. B., 12, 8, 69, B.M.M. VI, 90.)
