ZOOLOGY. 



jaws ; the pupae are active. Fritz Mtiller found in Brazil 

 that one species of Termes was difEerentiated into six 

 difEerent kinds of individuals : viz., a set of winged and 

 wingless females ; winged and 

 wingless males ; workers and sol- 

 diers. A male always lives with a 

 female, and a wingless male and 

 female may, on the death of a 

 winged normal male and female, 

 replace them. He found a male 

 (king) living with thirty-one com- 

 plemental females. In Calotermes 

 there are no workers, in Anoploter- 

 mes no soldiers. Termes deUicosus 

 Smeathman, of the west coast of 

 Africa, builds conical hills six feet or more in height.
