ART. 17. NORTH AMERICAN^ PHOROCEltA — ALDRICH AND WEBBER. 59 



Female. — Front 0.36 the headwidth (average of four, 0.35. 0.35, 

 0.35, 0.38) : third antennal joint three times the second. The shining 

 black apical half of each abdominal segment, contrasting with the 

 forceps short, scarceh' half as long as the inner ones, in the form of 

 the second and third segments of the abdomen, are quite character- 

 istic. 



Length of male, 4.5 to 9 mm. ; of female, slightly less. 



Redescribed from a long series of both sexes from all parts of the 

 United States, from Chihuahua, Mexico: others have reported it in 

 Canada from Vancouver Island to Ottawa and Eastern Canada. 



One male from Old Crow. Alaska-Yukon boundary, above the 

 Arctic Circle (J. M. Jessup, 1912). 



The type male of Podotachina vibrissata Brauer and Bergen- 

 stamm was examined by the senior author, December, 1923. 



Next to Winthemia quadripustulata Fabricius, this is probably the 

 most abundant Tachinid encountered in economic entomology. The 

 rearing records even in 1897 made a long list in Coquillett's Revision, 

 but that was only a beginning ; at the present time with the data in the 

 United States National Museum and in some branches of the Bureau 

 of Entomology it would not be difficult to lisl^ 100 rearings, on at 

 least 40 or 50 hosts. As a complete list of Tachinid rearing records is 

 likely to be published in the future we omit these to save space. 

 It usually attacks Lepidoptera, but occasionally sawfly and beetle 

 larvae.
