Madagascar, Comoro Islands and Eastern Africa.

The following brief account of the Acridoidea (Locustoidea) or Locustes collected by Prof. 
A. Voeltzkow in Madagascar and eastern Africa during portions of 1903 and 1904 has been prepared 
under difficulties which have delayed the report long after it should have been printed. Had this delay 
been anticipated in advance the work would never have been attempted by the writer. 
While the collection upon which the paper is based does not contain many of the more striking 
and remarkable forms of these insects that are known to inhabit the regions visited for their assembling, 
it does contain a score or more apparently undescribed forms. These latter are characterized herewith on 
the succeeding pages. 
It is perhaps worth stating that it was the present writer’s early intention not only to prepare 
a complete list of all heretofore described species coming from Madagascar, but also to review the recent 
attempts at adjusting the nomenclature so as to have it accord with the rules of priority, ete. as laid down 
by the committee of the International Zoological Öongress appointed for that purpose. All of this cannot be 
satisfactorily done at this time, hence the use of many of the long-used family and generic names instead. 
Family Tetrigidae. 
Agkistropleuron n. gen. 
Robust, apterous and bearing a very distant resemblance to some of the heavier species of Tetti- 
gidea; the face only gently oblique, the frontal costa widely furcillate and roundly produced between 
the antennae which latter are placed just within a line drawn between the lower edges of the eyes. Vertex 
not reaching in advance of the eyes and provided with a prominent median carina, nearly double the width
