ering the thoracic segments entirely and ventrally on the seventh to the tenth 

 abdominal segments. The rest of the body is green. The back centrally 

 is a little paler than elsewhere, especially on the metathoracic and first 

 abdominal segments, except in a dorsal line. Spiracles minute, black 

 ringed. Stemapods dark red-brown, twice annulated with whitish and 

 tipped with the same colour. Thoracic feet black; abdominal feet green. 



Third sfage : Head non-lustrous dark wine-red, paler on the lower 

 part, minutely but thickly mottled with little paler spots ; ocelli black ; 

 antennae pale; width 1.6 mm. Cervical horns tuberculated,each with a hair; 

 tails spinose. Thoracic segments, dorsal half of body nearly to spiracles 

 and the last three abdominal segments (joints 12 and 13) ventrally, 

 brownish vinous, as are also the " tails," but for the two broad whitish 

 annulations. The rest of the body is green ; the thoracic feet pale testa- 

 ceous. Piliferous tubercles as before. As the stage advances the brown 

 colour on the dorsum fades out on the posterior thoracic and first 

 abdominal segments (joints 3-5). leaving a triangular patch on the two 

 anterior thoracic segments (joints 2 and 3), which is narrowly connected 

 with the rest of the dorsal colour by a line on the metathoracic segment 

 (joint 4), that rapidly widens on the first abdominal segment (joint 5). 



Fourth stage : Head brownish wine-red, the upper two-thirds thickly 

 covered with little round reddish dots, but leaving a narrow line of the 

 ground colour on each side of, and parallel to, the central suture; paler 

 or yellowish at the sides posteriorly ; ocelli blackish ; antennae white, 

 brownish toward the tips ; width "2.5 mm. Cervical shield red- brown, 

 speckled like the head with little dots but less thickly ; the horns on 

 either side of it thick, round, tuberculated ; stemapods 9 mm. long, curled 

 up a little at the ends, spinose and coloured red-brown, twice annulated 

 with sordid white. The extensile threads are pinkish at base with a white 

 ring, the terminal part black. Body a little elevated dorsally on the 

 posterior part of the mesothoracic segment (joint 3) but without any 

 process on the metathoracic segment. It is pale green with a broad 

 ferruginous-brown dorsal band which is triangular on the first two 

 thoracic segments, covering the horns, narrows to a line on the 

 metathoracic segment and widening continuously again just reaches the 

 spiracle on the fourth abdominal segment (joint 8), after which it narrows, 

 reaching a minimum in the suture between the seventh and eighth 

 abdominal segments (though still quite wide), widens a little and slightly 

 contracts to cover the anal i)late. The band contains some minute
