GrRYLLID/E. 
97 
GtRyllid^j.— Crickets. 
Leafing insects , with usually long filiform antennae . The auditory organ 
is on the fore tibia. The wings are turned over at right angles from 
the dorsal to the lateral surface of the body. Tarsi three-jointed; 
female with a long ovipositor. 
Gryllidce are distinct from Locustidce in the tarsi and the wings; 
they are, however, a group which contain many different types of insects 
which hardly fall into one 
family and which, with further 
knowledge, will probably be 
split up. All do not have long 
antennae ; some have no ovi¬ 
positor, and in others the 
wings are not deflexed. If 
we remember Schizodactylus 
which may be a Gryllid, and 
are familiar with Gryllotalpa 
and Tridactylus, it is easy to 
realise that Locustidce and 
Gryllidce are hard to separate 
and that peculiar environ¬ 
ment has produced such 
changes in some forms that 
they scarcely come within the 
definition of the family. The 
Gryllidce as a whole are a 
large family not of great importance economically and not interesting 
to the ordinary student of nature. The Indian species are probably 
very imperfectly known. Brunner lists 43 species from Burmah of 
which he describes 20 as new to science ; Bolivar lists 35 from South 
India of which 14 were new. Kirby’s Catalogue lists 130 species 
from India, Burmah and Ceylon of which 80 occur in India. There are 
probably many new species to be found and there is much interesting 
work to be done in the biology of all of them. The works of Saussure, 
Brunner van Wattenwyl and Bolivar include the most important 
literature of the family as a whole.
