A lucid, illustrated explanation of the peculiar mechanism. The 
apparatus on the under side of the inner margin of one wing-case is 
drawn rapidly over the squamous surface of the corresponding upper side 
of the other, on which the vibratory flanges on the under side act ; the 
call is formed during the outward stroke of the wing-cases, which are 
slightly separated, and the insect assumes a statue-like position when 
stridulating. 
Hemimerus talpoides, Walker. Under the title, “ Spicilegia Entomo- 
logica Genevensia ; i. Genre Hemimerus^^ Saussure enters into a minute 
examination of this insect (placed by Walker in the Gryllidce), and 
arrives at the conclusion that it will not fit into any existing Order of 
insects, and he proposes for it a new one, which he names Diploglossata. 
The most extraordinary part of its structure is the presence of two super- 
posed palpigerous labia. Mem. Soc. Phys. Genev. xxvi. pp. 399-418, pi. i.
