Family Tryxalidae. 
The most striking forms of this family in the region from which the present collection comes 
belong to the genus Acrida. There are at least three species represented, and possibly four, but the last 
is based on an alcoholic specimen which has lost many of the distinguishing characteristics. 
Acrida brunneriana Bolivar. 
The A. dbrunneriana Bolivar is represented by at least 8 specimens all of which were collected 
in southwestern Madagascar at Tulear. While these specimens vary as to both color and size I do not 
believe that any of them could be referred to A. sangınnea Saussure. 
Acrida nasuta Linnaeus. 
This seems to be by far the commonest species of the genus not only in Madagascar but also on 
the adjoining islands and in British East Africa as well. There are at least two dozen individuals at 
hand including several nymphs. As in Europe it varies from plain uniform green to brown with white 
markings. 
Acrida subtilis Burr. 
Two males and two females of a third species are referred here. They were taken at Andrano- 
hinaly in SW. Madagascar. 
Acrida variabilis Klug? 
There are two female specimens (preserved in spirits) from Deutsch-Ostafrika which are placed 
here with some doubt. 
Calamus sp.? 
Four nymphs of a locust in various stages of development and poorly preserved are classed as 
belonging to Calamus. Wheter they belong to C. linearis Saussure, or to a new species, I am unable 
to decide from the material before me.
