The systematic part of this is practically an abridgement of Theobald's 

 Monograph, and contains descriptions of most of the North American 

 species all that were known at that time. 



The first edition was a different book, with less systematic work. It con- 

 tained one new North American species, Culc.v ivillistonii, which Coquillett 

 has since referred to his tarsalis.
