5? LLOYD'S NATURAL HISTORY. 



the larvae of the Swallow-tailed Butterflies, but they do not 

 appear to be protective, for instead of being exserted when 

 the larva is disturbed, as in the Equitida, they are retracted, 

 especially in darkness. The full-grown larva is about two or 

 three inches long, considerably thickened in the middle, and 

 slender at the extremities. On each side is a festoon com- 

 posed of many irregular bands of white, green, and yellow 

 points; the tentacles, which were at first of a delicate rose- 

 colour, become carmine-red, and the first pair of pro -legs 

 becomes almost rudimentary, causing the larva to " loop " 

 somewhat in walking, as in the Geometra. When at rest it 

 generally curves itself into a ring. The pupa is attached by 

 the tail, and by a belt round the body, as in the Equitidce and 

 Fiendce, and in the Ephyridce among the Geometra. The 

 pupa is conical, and but slightly angulated ; it is green, with 

 gilded bands placed horizontally from the head to the tail ; 

 the extremity is of a much darker green, and is sprinkled with 

 a great number of gilded points. 



It is to be regretted that the larva and pupa have not been 

 figured, for there are some ambiguities in the above description 

 which could probably be cleared up at once by a reference to 

 a figure. 



The Moth appears in about three weeks. When exposed to 

 the sun, it acquires its full development in two or three hours, 

 but the Moths which emerge in the shade take nearly a day 

 to develop, and are usually less brilliant. 



The East African species, C. croesus (Gerstaecker), is very 

 similar to the present one. C. madagascariensis appears in the 

 perfect state in September, but Sganzin states that a smaller 

 and very distinct species, which appears in March and April, 

 inhabits the neighbouring island of Sainte-Marie. I am not 

 aware that any further account of this insect has been pub- 

 lished, or any specimens sent to Europe. It is possible that it
