indebted to Edwin Brown, Esq., of Burton-on-Trent, in whose collection 
is a single example, with undeveloped elytra, captured by him some 
years since on or near the banks of the Trent. Hitherto the species 
had occurred only in France, but, from its small size, it may have been 
overlooked here by the few collectors of Hemiptera. There can be but 
little doubt that it is attached to some aquatic plant or plants, and 
Mulsant and Eey say " Hab. Fallavier (Isere), among the detritus of 
the marshes. Very rare." 
The structure of the insect conforms to the characters given for 
Section Hebrina (Brit. Hem., p. 25), with the exception of the antennae, 
for, including the 2 minute intermediate joints, Hehrus (onj^which
