Summary

The present paper gives an account of some experiments upon the insect Iphita limbata Stal. (Hemiptera: Pyrrhocoridae). The experiments were carried out in order to find out whether in the adult animal there is a relationship between the activity of the neurosecretory cells and the water balance. Under varying conditions one group of the neurosecretory cells of the pars intercerebralis of the brain, the so called “A-cells”, show histological differences. It has been seen that under conditions stimulating hydration there is a marked retention of the stainable colloids in the cytoplasm of “A cells”. This retention probably indicates a relationship between the secretions of “A cells” and the water balance of the insect.
