this Tutt says, " The palpus on leaving the maxilla passes backwards in 

 the angle between the head and the prothorax, until it is situated deeply 

 beneath the antenna, then it turns forwards to the antenna, and only 

 reaches the surface by emerging from beneath the antenna, and, turning 

 inwards, forms the ' eye-collar,' which contains only its terminal joints, 

 the others being concealed deeply." 



The 1st legs occupy all the space between the maxilla and the anteima, 

 and even follow the antenna for a short distance ; they are fairly broad 

 throughout, and end a little above half the length of the pupa ; the 

 terminal joints occupy almost the whole length of the maxillae. The 

 2Dd legs extend, along the antennae to about two-thirds of the total length 

 of the pupa, and are broadest opposite the termination of the maxillae. 

 The 3rd legs make their appearance beneath the 2nd legs, and, at first 

 constricted, are fairly wide opposite the end of the wings, and terminate 

 just above the end of the anal segments. « 



The anteimae are narrow, and, commencing above the eyes, extend 

 some distance beyond the terminal segments, more in some pupae than 

 in others ; their ends are free ; the joints are most conspicuous. 



The forewings are broadest opposite the 1st abdominal segment, and 

 rapidly narrow to a narrow, pointed, incurved tip just below the 6th 

 abdominal segment. The hindwings occupy a very narrow strip, which 

 is lost in the 2nd abdominal segment. 



The dorsal head-piece is large, prominent, well roimded posteriorly. 

 The prothorax is extremely narrow, and fonna a thin sunken strip behind 

 the head-piece. The mesothorax is large and prominent, sHghtly extended 

 behind. The meta thorax is medium-sized. The abdominal segments are 

 of about equal length, and gradually decrease in width towards the anal 

 end. There are indications of a dorsal suture in the metathorax and upper 

 abdominal segments. The free incisions are between segments 5-6, 6-7, 

 7-8. Segments 8, 9, and 10 appear to be soldered together. Spiracles are 

 minute and raised. There are indications of neuration on the wings. 



Duration of pupal stage from specimens obtained in August, twenty- 

 nine days ; in December, eleven days. 



Chief Measurements. 



The above measurements are, of course, subject to slight variation.
