Snellen van Volleniioven has commenced the publication 
of descriptions of the Dutch s[)ecies of this group (Tijdschr. 
voor Ent. 2*^® ser. iii. pp. 129-172). He divides the Geocores 
into the following families (pp. 136-137) : — Scutati, CoreodeSy 
Lygaodes, Pyrrhocorides, Capsiniy Tingidides, Hebroides, Corti- 
cicola, Anthocorides, Reduvini, Ripariiy and Hydrodromici — thus 
nearly following Burmeister^s arrangement. With regard to 
the genera admitted under his fa?nily Scutati, he also reverts
