A Handbook of Gnats or Mosquitoes. Second edition, London, 1902. 530 

 pp. ; many plates and figures. 



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, Ciilex zvillistonii, which Coquillett 

 has since referred to his tarsalis.
