with the setse arising from them well marked. They are included in 
the category “third interval with dorsal punctures.” 
Bembidium Latr. 
Antennae slender, arising under a slight frontal margin, the two 
basal joints glabrous. Head with two supra-orbital setae. Mandibles 
with a setigerous puncture in the scrobe. Palpi with the penultimate 
joint obconical, pubescent, the last joint small, subulate. Prothorax 
with a setigerous puncture each side and another in the hind angle. 
Elytra glabrous, striate, the margin interrupted posteriorly with an in¬ 
ternal plica; sutural stria not recurved at apex. Mesosternal epimera 
wide. Middle coxal cavities entirely inclosed by the sterna. Anterior 
tibiae deeply emarginate, the apical angle not obliquely truncate, ^.arsi 
slender, the claws simple. 
The males have the first two joints of the anterior tarsi dilated, the 
first slightly elongate, nearly quadrate, the second more or less triangu¬ 
lar, with the inner angle slightly prolonged. 
The species of this genus are very numerous. They are all below 
the average size, ranging from two to about nine millimeters. Most of 
them are riparial in their habits, though some are found in moss,, 
amongst old leaves or under bark, while a few occur almost everywhere.
