was placed in their box, they went to it and appeared 

 to drink it greedily. In the evening they would stand 

 on " tip-toe ' ' as it were, quite still for a long time in 

 the bright light under a table-lamp, whereas in the 

 daytime they liked to hide away out of the light as 

 much as possible. In the beginning of January these 

 examples, though they drank readily, seldom seemed 

 to wish to eat. 



Sharp mentions (' Entom.' 1910, p. 250) a case of 

 " maternal solicitude ' which he noticed on one 

 occasion in the Eastern Pyrenees, and (' Insecta,' i y 

 p. 214) that " this species is said to move its eggs 

 from place to place, so as to keep them in situations

DISTRIBUTION.- -L. riparia is found on the coast in 

 Southern Europe. In France it is common on the- 

 south coast, and has been found as far north as 

 Brittany. It has occurred near Geneva ; in Silesia, 

 Saxony, and Thuringia; near Berlin and near Vienna.. 

 It is common in Spain and Portugal in suitable 

 localities. In Britain it is known only from one or 

 two spots near Bournemouth. It has been introduced 

 into the United States, where it is found on the Gulf- 

 coast. Other localities are S- America, India, Ceylon, 

 Burma, Asia Minor, Transcaucasia, Carthage, Korea,, 

 Madeira, Cape Colony, Orange River Colony, Trans- 

 vaal, Rhodesia, Assumption, Cargados, Carajos Islands,. 

 Chagos Islands, etc. In fact it is now cosmopolitan, 

 although apparently a Palaearctic insect originally. 

 Outside England it occurs on river-banks, as well as 

 on the seashore.

It is unfortunate that this earwig occurs,, so far as is 

 known,, only along a small part of the south coast in the 

 neighbourhood of Bournemouth, where too it appears to be 

 getting more scarce. This is, of course, to be expected as 

 buildings increase around Bournemouth and Pokesdown, and

 roads and promenades. The late C. W. Dale, writing hi
