The most abundant of all the British species is the Clegg (Hcematopota pluvialis), which is particularly common in low, damp situations, where it is a gi-eat plague. This is a dingy, grey-looking insect, with a. greyish-brown body, and mottled-grey wings. It is distinguished generically from the Tnbani, which have antenuse of three joints, with the last deeply notched at the side, and ringed near the tip, by the possession of slender antennfe, in which the third joint is rather long, and followed by three short but apparently distinct joints ; it is also destitute of ocelli. The generic name, which may be taken to .signify " blood-drinker," is well conferred upon it. In the genus Pmi^/onia, several species of which inhabit the continent of Europe, especially in the south, the proboscis is very variable in length, sometimes being more than twice as long as the body.
