island. Five other specimens in Professor Haddon's collection 

 appear to be a variety of this insect. They differ from the type 

 in having the pronotum orange, instead of black, and in wanting 

 the large triangular black marking on the corium. Most of them, 

 however, show traces of this marking in small blackish patches on 

 various portions of the area which is totally black in the type. 



Dysdercus cingulatus (Fab.). 



Five specimens of this insect, which ranges from India to 

 Papua, were taken on Murray Island, besides larvae in various 

 stages of development. Three of the imagos are the ordinary 

 orange form, one the scarlet variety, and one the small pale variety, 

 solenis, Herr.-Sohaff.
