381-385) ; Formicidm (pp. 17-29, 71-84, 181, 219-229) ; fertilization of

Collecting. C. Lallemant, Pet. Nouv. vi. p. 372, recommends a

Nomenclature. Yon Harold is of opinion that the authors of 
catalogues are in a measure compelled to make changes in the case of 
double employment of names, and that such changes should not be 
restricted to monographers ; OR. Ent. Belg. 1874, pp. vii. & viii. A. de 
Borre would leave changes to monographers only ; 1. c. p4>. ix.-xii. De 
Selys-Longchamps agrees with Harold ; 1. c. p. xiii.
