98 THE COCCIDAE 



resembliiifr the plumes of a bird of paradise. These wax filaments 

 do not appear for five or six days after the emergence of the male 

 and require two or three days before they reach their complete 

 development. The stylus is a short conical spike from which pro- 

 trudes the penis which is very long and flexible. The wings are 

 large with an expanse of two-thirds of an inch. The halteres are 

 large and wide and each is provided with a single curved hook. 



The males transform in cocoons made of a mass of white 

 cottony threads of wax. They are placed on the ground among 

 leaves and under pieces of sticks and bark near the trunks of the 

 trees upon which the nymphs feed. The life cycle of the male or 

 female has not been described.
