Thus the number of species of the genus Dociostaurus reached 19. This number, 

 however, must be reduced to 10 only, since some of the species do not really belong 

 to this genus and others again must be regarded as synonymous, as follows : — 



Oedipoda histrio, Fisch. Wald. (Orth. Imperii Rossici, p. 311, pi. 32, fig. 6) belongs, 

 according to Fischer Waldheim, to the section of his genus " Oedipoda " with three 

 keels on the pronotum, the two lateral keels being straight or nearly so ; this is 

 not the case in the genus Dociostaurus, one of its chief generic characters being the 

 strongly angulated side keels of the pronotum. I am of opinion that Fischer 

 Waldheim's species is merely one of the numerous colour forms of Calliptamus 

 italicus, L. 



All five of Walker's species, as a study of the types in British Museum clearly 

 shows, belong to the genera Aulacobothrus, Bol. and Leva, BoL, and not to 

 Dociostaurus.'^ 

 ■ Stauronotus australis, BoL, can hardly belong to this genus, since it is described 

 from tropical West Africa, while all representatives of the genus are palaearctic 

 in their distribution. 



Stauronotus hauensteini, BoL, and Stauronotus kervillei, BoL, are synonymous 

 with Dociostaurus crassiusculus, Pantel, as I am convinced from a study of Bolivar's 

 types. 



Stauronotus tartarus, Stchelk., is not an independent species, but a geographical 

 race of Dociostaurus crucigerus, Kamb., as is shown below. 



Dociostaurus gracilis, Werner, though very unsatisfactorily described, is most 

 likely to be synonymous with D. genei, Ocsk. 



Unfortunately but few species of this genus (for example, maroccanus) are sharply 

 characterised, while the rest of them are extremely variable individually, their 

 variability being expressed not in coloration or dimensions only, but to some extent 

 in morphological characters as well. In consequence of this, it is quite easy to make 

 mistakes in studying representatives of such extremely variable species as crassius- 

 culus or anafolicus, unless very large series of specimens are available. Though I 

 have been able to study rather long series (more than one thousand specimens 

 altogether), I still think it impossible to give yet a full monograph of the genus, and 

 this revision must be regarded as but a preliminary one.
