This is one of the most extensive taxonomic, entomological works of 
recent years. Its completion has been delayed by the war, for while 
fascicules IX—XVI (Ire partie) were published in 1909-1913, the second 
part of fascicule XVI, comprising pages 1043-1278, although printed in 
1916, was not distributed, even in Belgium, until March 1, 1919. The 
cause of this delay has been explained by a note by M. Severin, in the 
News for October, 1919, pages 229-230. While part 1 of fascicule XVI 
terminated the main text, this last installment ot 1919 forms a supplement 
(pp. 1043-1228) to all the preceding fascicules,* gives a Verzeichniss der 
Literatur of the subfamily (pp. 1229-1245), a systematic list, with page 
*The largest collections furnishing the supplementary material are 
those of Mr. E. B. Williamson, of Bluffton, Indiana, made in Guatemala 
in 1909 and (with his father, Mr. L. A. Williamson, and Mr. B. J. Rainey) 
in British Guiana and Trinidad in 1912.
