CoQUEREL, referring to Westwood’s paper on the subject (see ‘ Record/ 
1864, p. 572), maintains the specific unity of the insects ascribed by him to 
Monanclroptera muncans (Serv.), and says that all intermediate forms occur. 
He confirms Westwood’s opinion as to Monandroptera spinigera (Luc.).

Prisopus. According to Murray, Prisopus Jlahellicorms (Stoll) is aquatic in 
its habits during the day, which it passes adhering to stones in the more 
rapid parts of streams and rivulets. At night it emerges and flies about. In 
adhesion the hollowed under surface of the body seems to act as a sucker. 
Murray supposes that Stoll described his Grillon aquatique cornu ” 
(= Ilenious stollUf G. R. Gray) as having aquatic habits by applying to it 
the accounts he had received of Prisoims, both insects being in his collection.
