Adults were about two weeks old when copulation was first 

 observed; egg-laying began the same or the following day. 



Full-grown larvae are very similar to those of Vcrmiiii frc- 

 iiata; but at the time of writing no specimens are obtainable, so 

 the exact distinctions cannot be given.

 x\ustralia ; Fiji. 



V crania sp. (PI. XV, fig. 12.)

HEMIPTERA. 



RED U VI I DAE. 



Zclus pcrcgrinus Kirkaldy.* (PI. XVI, figs, i, 3.) 



This insect was first known in the islands in 1897. It is not 

 known from whence it came, as it is not known elsewhere. It 

 first appeared in Honolulu, and has now spread to all of the 

 islands, being very common in many places. It is a pred'aceous 

 bug in all stages of its life, and is most commonly found upon 

 fruit trees and shrubbery which are infested with Aphis, and in 

 sugar cane-fields, where it feeds largely upon leaf-hoppers. When
