Acridoidea from Madagascar, Comoro Islands and Eastern Africa. 639 
Oxya serrulata Krauss. 
A number of specimens of both sexes of the O. serrulata of Krauss are at hand. They were 
taken at various localities in Madagascar (British East Africa) and on some of the adjoining islands. 
Parepistaurus deses Karsch? 
I find two individuals of a brachypterous locust that is referred with some doubt to Karsch’s 
Parepistaurus deses. One of the specimens is in color but the other was preserved in formalin. They 
were taken in the Comoro Archipelago, at Patsy Anjouan, during October, 1903. 
Acridium radama Brancsik. 
One male and three females from Central Madagascar are referred to this species. They are in 
color and are certainly very striking in appearance. 
Acridium deckeni Gerstäcker. 
Two specimens, a male and a female, that were preserved in spirits are at hand. They were 
collected on Patta Island (British East Africa). The female is very similar in structure to the following 
but is much larger than the same sex of that species. 
Acridium ranavaloae Finot. 
A single female of this species is at hand from southwestern Madagascar where it was collected 
during February, 1904. It bears the label Andranohinaly, Waldgebiet. 
Acridium ruficorne Fabricius. 
This is evidently the commonest species of the genus throughout the entire region visited during 
Dr. Voeltzkow’s collecting trip. Specimens are at hand from several localities, both sexes being re- 
presented by a number of specimens. 
& 
Acridium septemfasciatum Serville. 
While the present species is recorded as enjoying an equally wide distribution as the preceding 
only a single pair is represented in the collection now being studied. These insects come from Moheli, 
in the Comoro Archipelago. 
Acridium schistocercoides Brancsik. 
A number of specimens of both sexes are before me. They come from Tulear (SW. Madagascar). 
This insect is somewhat abnormal in from and color when compared with the other Madagascaren 
and African species of the genus. It will no doubt be set aside some day as the type of a distinet genus.
