The economic importance of Dociostaurus crucigerus, with its subspecies, is 

 not .so great as that of maroccanus, since it is a non-swarming and non-migratory 

 species, but still it is one of the injurious grasshoppers and does some damage to 

 grass and corn crops in Spain and Western Siberia, together with different species 

 of Stenobothrus and other grasshoppers.

Closely related to alhicornis, Ev., but always recognisable by the lack of the 

 longitudinal carina on the vertex. From D. crucigerus tartarus it may be distinguished 

 l)y the prominence of the upper part of the head. 



Geographical Distribution. This is not quite clear, since the species has been often 

 confused with albicornis and crucigerus tartarus, but it seems that it is a native 

 of the desert plains of Western Asia and North Africa, occurring also in some isolated 

 places in Southern Europe. 



There is nothing known about the economic importance of this species. 



4. Dociostaurus albicornis (Eversm.).

 1910. Dociostaurus albicornis, Kirby, Syn. Cat. Orth., iii, p. 157, no. 9. 



Though the difference between albicornis and genei is rather considerable, it 

 seems desirable that an examination should be made of large series of specimens 

 of both species, which may then prove to be conspecific. 



Geographical Distribution. Not so extensive as that of genei, since it is known 

 only from the Aralo-Caspian basin ; its occurrence in Germany, recorded by Azam 

 (Bull. Soc. Ent. France, 1913, p. 218) is almost certainly based on a wrong deter- 

 mination or a mistake in date. 



The economic importance of this species is unknown.
