rare. The South American genus, Nomadina, looks still more like 

 a bee, and the trochanters are even more imperfectly divided 

 than they are in some of the Aculeate group, Nyssonides, the 

 outer portion being merely a small piece imperfectly separated 

 from the base of the femur. 



Note. The citation of Saint Augustine on p. 85 is made in the words 

 used by Wasniann in Der Trichterivickler, eine naturivissenschaftliche Studie 

 ilbe7' den Thiermstinkt, 1884. 



The authenticity of the passage we have adopted as the motto for this 

 volume is somewhat doubtful. It is explained in an " admonitio ad lectorem " 

 of the soliloquy, that this work is probably a compilation by a later writer, 

 from two, or more, works of Saint Augustine, Father Wasmann has been so 

 kind as to inform the writer that the idea of the passage quoted occurs 

 frequently in the undoubted works of the Saint, as, for instance, de Civitate 

 Dei, lib. xi. cap. 22 ; Serm. ccxiii. in traditione symboh II. cap. i. ; contra 

 Faustum, lib. xxi. cap. v. etc. The passage quoted is, however, the only one 

 in which " angeli " and " vermiculi " are associated.
