'I'lic luiin]) on the 8th abthmiinal segment is now iccll 

 da'iiopcJ, /lii^/i, conical, and Jicsliy, s/i):;/itly inclined backward, dark at 

 tip, anil still bearing two bristles, though the dark chitinous 

 spint- is obsolete; the horn-like tubercle is half as high as the seg- 

 ment is thick. Tilt body behind the "caudal horn" narrows rather 

 rapidly to the end of the suranal jilate, which is larger than before, 

 but pale and of the same color as the body. 



The anal legs are used, but are about half as large as the 

 middle ones and with much fewer crochets, which are very 

 numerous in the middle legs, forniini:; a nearly complete circle. 

 The piliferous warts in general are now very much smaller and 

 paler than in stage I, being screen like the body, and scarcely visible 

 under a strong lens. The hairs are sparse, only one arising from 

 a wart, antl they are short and fme. 



In this stage the sub-prothoracic eversible gland was observed 

 in an alcoholic specimen. It forms a large transverse sack, 

 (bleached white by the alcohol, and contrasting with the red 

 skin of the side of the segment. It sends off two lateral sii)hon- 

 iike long ami slender finger-shaped diverging tubes, out of which 

 the spray is probably forced. Their ends do not reach to the 

 sides and are not visible from them, but the gland is much as 

 that of C'crura as figured by Poulton. (Trans. Ent. Soc. Loniion, 

 1887, PI. X, fig. 7). 



Sta^^e III. — Aug. 6. Length 11 mm. The head is now 

 pale amber, but still dusky on the vertex, and it is also still wider 

 than the body. On each side of the body is a faint whitish sub- 

 ilorsal line. The "caudal horn" is dark brown, now nearly as 

 long as the Sth segment is thick vertically. The horn is slightly 

 retractile in this stage, and the base is movable, being capable of 

 withdrawal and extension and is distinctly nutant, the apex some- 

 limes hanging over backwards. The sides of the botly along 

 the base of lK)th the thoracic and abdominal legs are now dark 

 reddish chocolate brown, being of the same color as the horn. 



77ic lateral yclloro line is well marked. i'he body beneath is 

 pale green. The spiracles form a dark dot surrounded by pale 

 greenish. 



Sta^e W . — Length 20 mm. Aug. 25. The body is now 

 thicker than before. The head is distinctly bilobed, rounded, 

 narrowing a little towards the vertex. The caudal horn is now 

 larger, higher and more acute than in the preceeding stage; it is 

 freely elevated or allowed to fall over backwards, is soft ami 

 tlexible, but very slightly retractile, and bears a few scattered
