No. 34-] HEMIPTERA OF CONNECTICUT I REDUVIIDAE. 677 



Family REDUVIIDAE. 



By J. R. DE LA TORRE-BUENO. 



This family contains the most voracious forms of the Heterop- 

 tera; they are the tigers of the herbs. They softly stalk their 

 prey, which seized in their spiny front legs is pierced with poisoned 

 lancets and sucked dry of its blood while struggling. The 

 majority live on plants, where other insect life is abundant and life 

 easy, but some spend their lives under stones or otherwise 

 concealed from the light of day. 



Our American forms are separated into the following sub- 

 families, the key being frankly artificial.

 the head and first joint Stenopodinae, p. 678 



8. Ocelli not as far apart as the eyes 9

Subfamily Saicinae. 



There is only one representative of this subfamily in the North, 

 namely, Oncerotrachelus. This genus is characterized by having 

 the anteocular part of head very short; apex of scutellum pro- 

 duced into a long spine; anterior lobe of pronotum wider than 

 long.
