SYNOPSIS OF THE CALLIPHORINAE OF THE 

 UNITED STATES. 



GARRY DE NORD HOUGH, M.I). 



Pollenia. — Four species of Pollenia are recorded : rudis 

 Fabr., vespillo Fabr., glabricjtla Big., and obscura Big. Rudis 

 is very common and may be recognized by its brown abdomen, 

 with white pollinose changeable spots. P. varia Meig. and 

 P. depf'cssa Meig. are small varieties 

 of 7'iidis. The description of P. ob- 

 scura Big. applies exactly to many 

 specimens of rudis. The abdomen 

 of vespillo is shining black (Fig. i). 

 Chrysomyia {Cornpso^nyid). — C. 

 macellaria Fabr. — Very common. 

 The metallic color of the body, the three black stripes on 

 the thorax, and the yellow face make it easily recognizable. 

 In this, as in all the Calliphorinae of metallic color, the shade

varies through violet, green, blue, and copper color, and since 

 the color of the legs, antennae, and palpi also varies, it is not 

 strange that its synonymy is too extensive for this article (Fig. 2).
