C. ramsayi full fed length 3 inches. Colour : Head reddish 

 brown ; Prothorax, very pale brown ; thoracic and abdominal 

 segments, yellowish. Head smaller than Prothorax, abdominal 

 segments 3 to 7 are larger than the anterior and posterior segments. 

 Prothorax scutellum has within the black concavity three setge. 

 Terminal hooks of abdominal feet complete, anal claspers as 

 before described. Tubercle setse smooth. Skin smooth. 



(IV.) C. virescens live (?) three years, there is a great 

 difference between the larva? which may be regarded as full fed, 

 some about 3 inches, some about 4 inches, it is not improbable 

 that the larva? which produce female imagines, live a year 

 longer than those which produce males. The larvfe of C. 

 virescens are described elsewhere,* but it may be worth noting 

 that the black concavity of scutellum contains three setae in 

 young larvae, but one only in adult larvae, likewise in young 

 larviB the terminal hooks of abdominal feet are incomplete, but 

 in full fed larvae they completely encircle the extremity of the 

 abdominal feet. It might also be worth mention that these 

 larvae, and probably the other species also, vary in colour much 

 in accord with the colour of the sap wood in which they feed. 



PUP.E. 



The pupal stage is of short duration, " from six weeks 

 to occasionally as long as three months (Illidge). 



(1.) C. daphnandrae pupa. Colour: Head and prothorax 

 very dark brown, remaining segments are yellowish brown 

 with reddish shading on posterior edge of segments, spines 

 and spiracles are dark brown. 



Head dorsally and ventrally, dorsum of Prothorax, and 

 anterior dorsal area of Mesothorax are deeply pitted and 

 striated in a manner resembling that of the larval caput. The 

 wing cases extend to the anterior edge of abdominal 3 ; antennae 

 extend only to base of wing cases of which the second pair of legs 

 forms the costal margins, the first pair of legs are inner to 

 the second. Margin of hind wing cases show a little at the 

 outer margin of the fore wing cases. Abdominal segment 1 is 

 dorsal, small and without spiracles ; 2 has spiracles subdorsal 

 and apparently partly covered by edge of wing cases ; 3 to 6 

 have normal spiracles in lateral position, these segments 

 also have setie — small but definite, which correspond in 

 number and position to the larval tubercle setfe ; 7, 8, have scars 

 of spiracles, the four terminal segments are fused together.
