GEOCORIS. 29 



Mr. L. de Niceville sent me, for identification, a number of not 

 fully-developed specimens which were then infesting and doing 

 much damage to sugar-canes at Cawnpore. 



Subfamily IV. GEOCORINtE. 



The broad head, recurved from in front of eyes to apex, gives the 

 species forming this subfamily a very distinctive and unmistakable 

 appearance. The subfamily contains but few genera — Geocoris, 

 the only one found in British India, being its dominant repre- 

 sentative. The Geocorinse are almost universally distributed.
