Kershaw and Kirkaldy, in their metamorphosis paper have added to 

 our knowledge of Hemipterous life-histories, but that wealth of references 

 which ordinarily characterizes the work of the junior author is regrettably 

 absent. They treat of a Scutellerine and a Coreid, the former Chrysocoris 

 Stollii, Wolf, and the latter Riptartus linearis, Linne. The female of 

 the first-mentioned lays about a dozen eggs on leaves, mainly belonging to 

 several species of Glochidion, on the fruit of which the bug feeds in all 

 stages, although it accepts other fruits. This adaptability to other food 

 than the normal is not uncommon among the Hemiptera, as my observa- 

 tions on Nezara hilaris, Brochymena qaadripustulata and Acanthocerics 

 galeator have shown me, for the nymphs of these three species, while in 

 nature feeding on golden-rod, trees and other wild vegetation, all throve 

 and came to maturity on plants of the cultivated bean. The authors de- 

 scribe the manner in which the eggs are deposited, and note the changes 

 of colour and markings caused by the advancing development of the 

 embryo, a process which can be very readily observed in the white ova 

 of various water-bugs. The nymphs hatch in four days. Unfortunately 

 the number of nymphal instars was not positively ascertained, but I am
