In my key to the species of the genus Tanypremna (Journ. N. Y. 

 Ent. Soc, vol. 22, pp. 207, 208; 1914) this species falls naturally into 

 the first group of the genus, longipcs (Fabr.), manicata O. S. and 

 longissima (End.) from all of which it differs notably in the uni- 

 formly dark-colored tarsi.
