perpendicular shaft as in C. daphnandra'. Length of burrow^ 

 about one foot. 



The larva* of each species can hang by a thread of silk, and 

 we have noticed that the perpendicular shaft of C. virescens is 

 thinly lined with silk threads. Unfortunately, we have no 

 description of the newly-hatched larvie of either species. Apart 

 from the interesting habits of these insects, we hope a de-scrip- 

 tion of their structure will have a scientific value. It is hardly 

 necessary to mention that these larvae are bilaterally symmetrical,, 

 and the segments are as follows : — Head, Pro-Meso, Postthorax, 

 each with a pair of legs, and ten abdominal segments, some of 

 which have feet.'"' 



(I.) C. daphnandra' larva- live nearly two years (lUidge) ;. 

 at six months the length is about ^ inch. Colour : Head, dark 

 reddish brown ; Prothorax, pale brown scutellum ; remaining 

 segments, cream colour. Spiracles are brown with outer rims. 

 Thoracic legs, brown. Abdominal feet and claspers, cream 

 colour with dark brown terminal hooks. Sette are brown with 

 minute blunt thorns. The skin is comparatively smooth. The 

 head is larger than succeeding segments, larva tapers to anus. 



Head : striated, seta* numerous ; ocelli, six in number on 



each lobe, arranged in two rows of three each, they are yellow 



-with a black area on inner side ; antenna- are immediately 



anterior to the two lowest ocelli ; spinneret is long and slender. 



Prothorax : anterior edcre of scutellum darker with a 

 marginal series of seta- equidistant ; a midlateral concavity or 

 scutellum is apparently lined with soft down-like hairs, within 

 the concavity are three seta?, and below it one seta. The 

 spiracle is immediately posterior, below the scutellum, and about 

 twice the size of the abdominal spiracles ; anterior to the legs a- 

 tubercle bears two seta-, on base of legs are two anterior and one 

 posterior hairs, and at the lower end of each joint there are 

 several hairs. 



Mesothorax : a small anterior subsegment bears the dorsal 

 (trapezoidal ?) tubercles with one seta, and a small lateral 

 tubercle with one seta. The larger subsegment bears on 

 either side a marginal series of three equidistant setae, 

 and one posterior lateral seta all on one well defined area- 



* Abdominal feet proposed by Dr. Sharp to be used instead of the older 

 term prolegs, pro being usually the term for anterior, whereas in larvee the 

 thoracic legs — identical with imaginal legs, are the anterior legs. The term 

 abdominal feet seems more appropriate.
