210 THE ENTOMOLOGIST S RECORD. 
It seems to have been originally a Palearctic species, and is to be 
found on river-banks, and among the shingle of the coast in southern 
France, also along the Mediterrenean Sea, in Asia Minor and the 
Transcaucasus, and again in Korea. It is to be found also in nearly 
every port in the world, and in South America has developed some 
remarkable varieties. It varies considerably in size, colour and form, 
and most forms have been described as separate species. 
Anisolabis maritima, Bon., 1s a species with similar habits to the 
last; it is also probably Palearctic in origin, but is now cosmopolitan. 
Its occurrence in England is purely artificial. It was discovered in 
numbers nearly fifty years ago, near South Shields, among heaps of 
refuse consisting chiefly of ballast from ships returning from abroad. 
It is uncertain how long the species maintaimed its hold there, and 
whether it is still in existence there. 
Anisolabis annulipes, Luc., is also cosinopohtan, and an introduced 
species with us. [The genus Anisolabis is represented throughout the 
world. | 
Labia minor, L., is the typical species of a large genus with a world- 
wide distribution.  L. minor is essentially Palear ctic, and is common 
throughout Europe. It occurs in North America, but is there an 
introduced form. 
Ietobia lapponica, Li., occurs throughout Kurope from the Volga to 
Lapland. Ihave taken it in Wallachia, and in the mountains of 
Bosnia and Hercegovina. In Lapland it destroys the dried fish of 
the natives. With us itis local but not rare. It is not a native 
of southern Hurope proper except in the mountains. It has been 
taken on Mount Etna. 
Ketobia panzeri, Stephs., is common in Belgium, Holland, France 
and the south of England. It is rare in Germany and has been taken 
sparingly in Dahnatia and Ferrol. 
HMetobia livida, Faby.—The distribution of this species is similar to 
that of 1’. lapponica, but more southern. In the north it is rare, but 
occurs In Germany. It is common throughout central Europe, and 
abundant in the south. 
The genus HKetobia contains about half a dozen species ; those 
which do not occur with us are essentially southern in distribution. A 
closely allied genus, Aphlebia, contains many more species and is more 
widely distributed. It is not yet known to be represented in this 
country, though some of the commoner forms might turn up (e.g., 4. 
maculata, northern France, Belgium, Switzerland, or 4.punctata with a 
similar distribution). No other cockroaches are indigenous in this 
country. 
Mecostethus yrossus, li., is the only species of the genus. It is more 
or less common in the marshes throughout the whole of northern 
Hurope, as far as Lapland. . 
Stenobothius is a large genus, containing about fifty species, 
distributed throughout the the Palearctic region. No true species of 
the genus occurs outside its boundaries, though extremely closely 
allied forms occur in North America. Brunner divides the genus into 
five groups or subgenera, of which four are found in Britain, ‘Though 
it may be sometimes considered hard to distinguish our species, it 1s fa 
more difficult to discriminate the European forms, which are so humer- 
ous, and which come between onr familiar species in the systems.
