CIDARIA P1CATA. 83 



from pale olive-green to reddish -brown. The whole 

 of this space is of two shades, the lighter represented 

 by very irregular lines, at one time confluent and 

 then separate, with very irregular edges. There is a 

 black patch in the middle of the seventh, eighth, and 

 ninth segments ; this becomes less distinct as the 

 caterpillar increases in size, and in some cases alto- 

 gether disappears. The sides below the spiracles and 

 the ventral space are of a lighter shade than the 

 back, the line of demarcation being well defined. The 

 whole of this portion bears a considerable resemblance 

 to the back, as far as the markings are concerned, 

 being made up of very irregular lines of alternate 

 darker and lighter shades. The legs and claspers are 

 of the lighter shade. At the sides of the junctures of 

 the segments there are spots of a much darker colour. 

 The spiracles are black. 



The caterpillars disappeared about the end of the 

 first week in September, making a slight cocoon on 

 the surface of the earth, and changing to a chrysalis 

 of a light reddish-brown. 



In confinement it is double-brooded. During the 

 second week of September, 1874, I had a few imagos 

 emerge from the pupae of a brood which fed up about 

 the middle of August. (P. H. Jennings, September, 

 1874; Entom., October, 1874, VII, 230.) 



ClDARIA SAGITTATA. 



Plate OXLIII, fig. 1. 



The larva of Cidaria sagittata is rather short and 

 stout, generally being in a hump-backed posture, but 

 not curling in the front segments. The head is small, 

 and sunk in the second segment ; the skin on the front 

 and hind segments is wrinkled, whilst across each of 

 the segments from the fifth to the tenth (both in- 

 cluded) there runs a transverse elevated ridge, which 

 on each side of the spiracular line meets a longitudinal
