This common European species has been widely introduced in temperate 
North America and has as surely reached the Antipodes by the same means. 
STENIXUS new genus. 
A monotypic genus, including only S. rhachynotus, is here described. 
The very small longitudinal pronotum but large head and broad organs of 
flight suggest Opisthocosmia Dohrn, but the male abdomen with ultimate 
tergite narrow and both sloping and narrowing strongly caudad indicate closer 
affinity to Narberia Burr. 
The remarkable tooth at each latero-cephalic angle of the pronotum 
readily distinguishes the genus, which is further characterized as follows. 
Size medium small, form extremely slender. Head moderately tumid 
with sutures distinct. Antennae with twelve segments, all very elongate and 
cylindrical except the minute second. Organs of flight fully developed ; tegmina 
ample, not keeled. Abdomen with second lateral tubercle prominent and its 
apical glandular development distinct. Male abdomen scarcely widened meso- 
distad, unarmed laterad. Pygidium very small and narrow in both sexes. 
Forceps elongate and slender, of male nearly contiguous throughout. Limbs 
very slender, tarsi very small, caudal metatarsus very slightly longer than 
combined length of the two succeeding joints. 
Stenixus rhachynotus new species. Text-figures 3 ancl 4. 
This is not only one of the slenderest but also one of the most 
distinctive of the knowm earwigs.
