158 Llemiptera-fTleteroptera. 
are recorded as Palearctic, belonging to twenty-nine genera. 
The species are carnivorous. 
The family may be distinguished by its short, bent ros- 
trum, which does not lie against the under surface of the 
head when in repose, its filiform antenn, its prominent 
eyes, situated as a rule far away from the pronotal margin, 
and its ocelli (when present) situated behind the eyes ; 
elytra often not fully developed, but when developed, con- 
sisting of corium, clavus and membrane; lees with the 
anterior femora generally incrassated, although scarcely so 
in Ploiaria, in which genus all the legs are exceedingly 
thin and elongate.

Elongate, with extremely long, fine antenne and legs. 
Head rounded posteriorly behind the eyes, eyes prominent, 
ocelli wanting, vertex with a strong transverse impression ; 
antenniferous tubercles strongly developed ; antennz very 
long, first and second joints subequal, third and fourth 
together about half as long as the second; rostrum scarcely 
longer than the head; pronotum slightly widened behind, 
its sides nearly straight and carinated ; scutellum with two 
spines, one at the base the other at the apex, below the 
apical one is another, which appears to me to be on the 
basal segment of the abdomen, although Dr. Puton con- 
siders it “sur le scutum du metathorax ;” elytra suabmem- 
branous, membrane very large, corium produced along each 
side of it into a long, narrow point; legs very long and 
thin ; coxze elongate, especially the anterior pair, which are
