and white at first, but remaining quiet, in a few hours it becomes 

 hardened and its normal coloration appears. 



The following is a summary of the life history: 



Embryonic Period 4 days 



Larval Period 11-13 days 



Pupal Period 4-6 days 



From maturity until egg-laying begins 7-20 days 



From deposition of egg till ready to lay eggs again. 25-43 days 



Egg-laying period about two months. 



There is practically about a brood per month, throughout the 



year. 



HAB. Southern Queensland, Bundaberg and Brisbane, Aus- 

 tialia, on Aphis of Ficus. 



Cocci Jiclla re panda, Thunb.* (PI. XV, figs. 5-7.) 



This ladybug was introduced from Australia several years 

 ago. and is now distributed over all the islands. It is very 

 abundant in many places, and feeds upon all species of Aphis. 

 It is found in the mountains, in the valleys, in gardens, orchards 

 and grounds, and in sugar cane-fields. Although an aphis feed- 

 er, in cane fields it feeds to a considerable extent upon young 

 leafhoppers, especially at times when cane Aphis is scarce. 



This species is of medium size, 5.5 m'm. long by 4.5 broad and 

 very convex. It is recognized by the color of the elytra, be- 

 ing orange-red (often paler) with 9 irregailar black spots, and a 

 black line in the middle of the back, produced by the black mar- 

 gins of the elytra where they come together. The prothorax is 

 black on posterior portion ; anterior portion yellowish, boundary 

 line between is irregular. Head yellowish, with black eyes. 



(i). Life History. 



The eggs are yellow, often very pale, i mm. long. They are 

 deposited on end, on the under side of leaves 'and other shelter- 

 ed places, in clusters of from 2 to 18, 10 or 12 being the usual 

 number. They hatch in 3 or 4 days ; the larvae are black with 

 white markings. They grow rapidly and molt 4 times, including- 

 the molt which takes place at pupation. The interval between 

 molts is I to 2 days, and the whole larval period is 8 to 9 days, 

 depending upon abundance of food supply. 



The full-grown larvae are 8 mm. long. (PI. XY. fig. 6.) They
