Colobathristince .—A single species will be found, the slender Artemi- 
dorus pressus, Disk, in which the base of the abdomen is contracted into 
a distinct “ waist.” 
Heterogastrince .—Four rare species occur in India, and Dinomachus 
rhacinus, Dist., common on tree trunks. Epibomius Pusa, Dish, is also 
known. 
Pachygronthince. —A single species, Pachygrontha dixoni , Dist., was 
found in Bombay.

little Dusky Bug of Cotton, Oxycarenus Icetus, Kby., common throughout 
the cotton growing areas of India. The eggs are laid in the lint near the
