200 Mr. F. L. Davis on larva and pupa of CaJigo memnon. 



the longest and measure one-fifth of an inch in length. They are 

 directed backwards, as are the otliers, and gradually diverge from 

 each other, producing a V-like figure, the point of the V being at 

 the attachment to the head. The anal extremity terminates in a 

 forked appendage about half an inch in length, and closely covered 

 with short whitish hairs. The prolegs are a bright reddish brown. 

 The pupa is 1^ inches in length; colour a yellow drab with 

 blotches of grey irregularly scattered over it. The wing cases are 

 rather strongly angled and stand out at right angles to the rest 

 of the body. In the centre of the wing case, at its upper part is 

 a double silver spot ('•) both parts of which are of small size but the 

 upper is the larger. There is a well-marked thoracic hump on the 

 dorsal surface. A thin dark brown line extends the whole length 

 of the dorsum, and from this line and on each side of it spring tufts 

 of very short small and fine black bristles. 



Both pupae were photographed, and the photos accom- 

 pany this Paper. 



One imago emerged on the 12th January, 1915, but was, 

 as I expected, malformed.
