Pupation of Botys verlicalis. — About the middle of June, 

 on opening one of the many roUed-up leaves of the common 

 nettle (Urtica dioica), the full-fed larva of Botys verticalis is 

 perceived lying snugly ensconced therein. Should the ob- 

 server be desirous of vvatcliing its pupal changes, he will find 

 that, just before the caterpillar is ready to enter the pupal 

 stale, the form and colour of the anal segment is clearly 

 visible through the skin ; and that as it slowly passes into a 

 chrysalis its head, thorax and wing-sheaths are of a beautiful 

 apple-green colour ; the abdominal segments are pale green 

 mottled with white ; the dorsal pale green, and visible 

 throughout its entire length ; the anal segment of the pupa is 

 of a dull pink colour, and armed at its extremity with a 

 cluster of hooked bristles. After the expiration of an hour or 

 so, the observer will further notice that some of the mottled 

 markings on the abdomen begin to change to a cream-colour: 

 be is then intei*ested in observing that the head and thorax 

 are gradually turning whitish, whilst on the other hand the 

 segmental divisions of the abdomen are green ; the creamy 

 coloration situate on certain parts of the abdomen is observed 

 slowly to assimoe a pale pinkish or flesh tint, particularly 

 noticeable on the 1st, '2nd, 3rd, 4th, 5th, 6ih and 7th of those 

 segments, changing gradually into a pale brown tone. After 

 an interval of about a coujile of hours, the head and thorax 

 become pale brown : it is then seen that the base of the ven- 

 tral surface of the 4th, 5th, 6th and 7th abdominal segments 

 have become partly surrounded by a semicircular band com- 

 posed of dark pigment, and are faintly seen through the pos- 

 terior portion of the transparent green-coloured wing-cases. 

 On turning the pupa on to its breast, we then observe that the 

 dorsal surface of the above-mentioned segments are not pos- 

 sessed of a semicircular band, but of a dark brown-coloured 

 central mark or blotch : these latter, however, after a time, 

 throw out fresh pigment, and spread themselves right and 

 left until they come in contact with the ventral bands, and,
