considerable more work in this family before we can follow the 
connection of the groups of genera. It is highly probable that 
it will be divided into two or more families. 
The following is a slight modification of Melichar’s table. I 
treat the groups as representing two subfamilies and seven 
tribes.

I consider that the Upper Permian fossil Prosbole can be 
placed within this family. It is very similar in venation to the 
living insect Neommatissus Muir, and to Trobolophya Mel. I 
cannot consider it in any way ancestral to the Heteroptera. It 
has no median furrow, and the posterior furrow (suture) 1s 
behind the cubitus and not between it and the media.

This family contains about ninety genera. Every collection of 
any extent received from the tropics contains new species and 
genera, and when the tropics of Africa and America are explored 
for these insects the number of species will soon be doubled. 
The eggs are unknown, but they must be laid in rotten wood, 
or under bark, for that is where the nymphs are found. In 
some genera the ovipositor is absent or represented by mere
