which soon transforms to a true pupa (), from which the beetle (F) 

 shortly emerges. Thus the pupal stage is preceded by at least three 

 distinct larval stages. 



Strepsiptera, the subject of two important volumes by Dr. W. D. 

 Piene, are all hypermetamorphic. These parasites affect almost 

 exclusively Hymenoptera and Homoptera, causing the u stylopized" 

 condition known to collectors of bees, wasps or bugs, in which the pres- 

 ence of the parasite is indicated by a flat disk-like plate (in the female 

 or a tuberculate rounded projection (male) protruding from 

 between segments ctf the abdomen. The male is winged but the female 

 is maggot-like and sedentary, a mere sac of eggs, often two thousand 

 or more in number, which hatch inside the body of the mother into active 

 little hcxapodous thysanuriform larva.' known as trhtngulinids. These
