SYNOPSIS OF THE TACHINID FLIES OF THE GENUS 

 TACHINOMYIA, WITH DESCRIPTIONS OF NEW SPECIES 



By Rat T. Webber 



The genus TacMnomyia was erected by Townsend (1892, p. 96) 

 for the reception of two new species, robusta and -floridensh. He 

 designated the former as genotype. Coquillett (1897, p. 118) con- 

 sidered the genus a synonym of Taehina {= Exori.^ta) ^ as also did 

 Aldrich (1905, p. 469). According to Townsend (1908, p. 107), how- 

 ever, TacMnomyia "differs from Taehina in the vibrissae being in- 

 serted higher above oral margin, cheeks one-half eye height in width, 

 and abdomen very elongate."' Since these characters vary to some 

 extent, more important, perhaps, is the structure of the genitalia, 

 which, as pointed out by Curran (1926, p. 166), are entirely different 

 from those of Taehina. 



The writer wishes to acknowledge the assistance given him by the 

 late Dr. J. M. Aldrich, who prior to 1926 made a study of the 

 material at the United States National Museum and was prepared to 

 recognize Tcwhinomyia., with new species included, but did not pub- 

 lish because of the appearance of Dr. C. H. Curran's paper (1926) ; 

 to Miss Daphne x\ubertin, of the Department of Entomology, British 

 Museum, for the comparison of material with Walker's types; and 

 to T. H. Jones for the use of material and notes of his making. 

 Appreciation is expressed also to David G. Hall for his suggestions 

 and advice. That which follows is the result of the writer's study 

 of material at the United States National ^luseum, and at the 

 laboratory of the Bureau of Entomology and Plant Quarantine, 

 United States Department of Agriculture, formerly maintained at
