122 Second Report on Economic Zoology. 
Senegal, are species of the Orthopterus family, Hemimeridve, of which 
little is known. They come near the Blattidse or Cockroaches, and 
form a connecting link between them and the Forficulidae or Earwigs. 
There are only two species known, and both are apterous insects. 
Walker described one species from West Africa as Hemimerus 
tcdpoides. Hagen, the most recent observer, undoubtedly describes 
another, which Sharpe calls H. hccnseni. The ones taken by Dr. 
Dutton are that species. Hansen’s species was found on the rat-like 
Cricetomys gambianus in Equatorial West Africa. It occurred on a 
few specimens only of the mammal, but when found was present in 
considerable numbers. It is recorded as running rapidly amongst the 
hairs, and it is said to spring. The young are born inside the mother, 
six at a time. What they feed on, their structure and economy, 
require working out. They may be parasitic on other animals 
as well.
