THE TACHINID GENUS ARGYROPHYLAX B. & B. 



BY W. R. WALTON, Bureau of Entomology. 



This genus was proposed by Brauer and Von Berganstamm 1 

 for the reception of a single individual from St. Thomas, West 

 Indies and described many years previously by Wiedemann 2 

 as Tachina albincisa. An additional specimen of the latter 

 species was discovered by Van der Wulp in the Biologia Centrali 

 Americana 3 material which specimen he states Professor Brauer 

 saw and identified as Argyrophylax albincisa Wied. I have re- 

 cently received two specimens reared at Rio Piedras, Porto Rico, 

 January 24, 1912, by T. H. Jones from Nacaleia indicata Fabr. 

 These specimens seemed to be identical with Van der Wulp's 

 specimen mentioned above, although his description of the 

 same is very brief. Therefore in order to allay all doubt as to 

 the matter I have secured a comparison of one of the reared
