562 Mr. C. L. Witliycombe's Notes on 



is from June until August, sometimes later in autumn, 

 wliich is rather a long period on the wing for a Chrysopa, 

 and suggests the possibility of two broods. 



The eggs are laid in a similar way to C. flava, the stalks 

 being united in a bundle. Each egg is -8 mm. long, pearly 

 white in colour when first laid, sometimes with a tinge of 

 green. As hatching approaches, the colour changes first 

 to pale buff, then brown, and then greyish-brown. The 

 stalks are 6-7 mm. long, fixed to the undersides of leaves, 

 close together in a bundle. These eggs may be distin- 

 guished from those of C. flava by their slightly smaller size, 

 by the more flimsy stalks, and consequent closer hanging 

 together of the eggs in a terminal cluster. 



The young larva is white with a dusky head, the blackish 

 markings almost covering it. The body bears well- 

 developed setigerous warts, and the general facies is much 

 Uke that of C. jyrasina. The second-instar larva is similar 

 to that of the third, but the head markings may be a httle 

 less separated. A coat of debris is carried throughout life. 



Description of Third-instar Larva. (Plate XLI, fig. 5.) 



Length 6-7 mm. Head markings similar to those of C. tenella, 

 body white, with setigerous warts as in C. prasina. 



The head is whitish with dark brown markings. These are of 

 the same pattern as those of C. tenella, but usually bolder. There 

 is a pair of diverging lines from the middle of dorsal surface to the 

 anterior margin. From base of head a pah* of lines runs forAvard 

 diverging to the antenna bases, outside these, and jiarallcl to them, 

 another line on each side runs towards the eyes. On either side of 

 the head is a broad black line. Eyes black; antennae and jmlpi 

 grey; jaws castaneous. 



Body white, best contrasted with C. prasina, from which it 

 differs as follows. The thoracic warts are larger. The setae from 

 these are sj^read more laterally and fan-like from each wart. Pro- 

 thoracic sclerites grey, consist of two outer large sclerites and a 

 trace of a median sclerite, not, as in prasina, large. Meso- and 

 metathorax have each a pair of grey sclerites. 



Abdomen with smaller warts and also hooked setae for carrying 

 debris. The contents of the stomach often show through the skin, 

 blackish. A dark median dorsal line runs the greater part of the 

 body length. Underside whitish. Legs grey or fuscous. 



Likely to be confused with either C. ^wasina or the
