EXPLANATION OF PLATES. 



The photographic illustratious of the habit characteristics of the various 

 species shown in these plates have, vt^ith the single exception noted, been pre- 

 pared by Mr. J. G. Pratt, photographer for the Bureau of Entomology. No 

 attempt has been made to photograph the insects to a definite scale of enlarge- 

 ment, and the text of this paper or Maskell's publications should be consulted 

 for information as to the actual size of each species. Due either to the poor 

 <*ondition or the lack of material of a number of Maskell's species, it has not 

 been possible to obtain photographs of them, and in consequence the series is 

 not complete.
