ESSAI SUR LA FAMILLE DES VESPIDES. 

 Par M. H. de Saussure. Vol. III. 8vo. 



Mr. "Westwood has obligingly furnished me with the following 

 notice of this work. 



" The third volume comprises the social wasps (the solitary 

 wasps Eumenides, and the false wasps Masarides, being treated 

 upon in the two former volumes). The number of social species is 

 much smaller than that of the solitary wasps, but the plates are 

 rendered very interesting, by the introduction of great numbers of 

 nests of various forms and textures."
