Extract

The host of the Coccidian described in this paper is Hydroporus palustris L., a small Dytiscid beetle common in stagnant ditches. The infected material was collected from two ditches in the neighbourhood of Grantchester (Cambridge). From one ditch 25 per cent. of the beetles were parasitised, and from the other ditch 15 per cent. were parasitised. The infection with Legerella, which is confined to the malpighian tubules, is often very intense. Heavily infected beetles are readily recognised on dissection because the malpighian tubules are colourless and do not contain the brown excretory granules characteristic of the normal tubules. The parasite has been observed at all seasons of the year, and the life cycle does not appear to follow a seasonal course.
