432 rROCEEDINGS OF THE THIRD ENTOMOLOGICAL MEETING 



spirals on tlie lower surface of leaves. The eggs when laid freshly are 

 pale yellow but when they are matured they turn orange-brown. They 

 are elongate oval, somewhat concave in the middle. They are attached 

 to the leaf surface by means of short, thick, slaty-grey peduncles. If 

 examined under the microscope the chorion seems to be tessellated 

 finely vnth hexagonal patterns. The number of eggs laid by a female 

 has not been determined. In a number of eggmasses examined the 

 number was found to be : —

In some cases the spirals forming eggmasses crossed each other and in 

 others, when a number of females had oviposited close to each other, 

 they formed broad spots on the lower surfaces of leaves. 



The nymphs on hatching fix themselves near the empty eggshells 

 and move but httle. When the adult emerges, a longitudinal sht opens 

 on the cephalo-thorax dorsally and the head is thrust out. A few 

 minutes later nearly half the body is out of the puparium. It then 

 struggles from side to side and stands bolt upright within the sht on 

 the puparium. The lateral motions are continued until it is clear out 

 of the puparium. It is then bright yellow with eyes deep maroon. 

 The wings are crumpled and remain pressed against the abdomen laterally. 

 As they get aerated they continue to expand. Twelve to fifteen minutes 

 after coming out of the puparium the adult begins to move about. The 

 male puparia may be distinguished easily from the female puparia on 

 account of their size ; they are much smaller than the latter. The honey- 

 dew exuded by the adults is so profuse that it hes thickly on the leaves 

 and gives rise to a fungus, Clasdos'porimn sp., along with the sooty- 

 mould found so profusely on the leaves. 



During August 1909 a number of grubs of Chrysopa fidvolineata 

 was seen actively running about the infested leaves with the remains 

 of their victims on their backs. On the 18th August 1909 three grubs 

 were found on a leaf and from 19th-27th August 1909 they were fed 

 exclusively with the nymphs and puparia of the Aleyrodid. On the 

 28th August one of these pupated and emerged as an imago on the 6th 

 -September 1909.
