Strumigenys venatrix Wesson and Wesson Synony- 
mous with S. talpa Weber. — In the course of his studies 
of dacetine ants, Mr. William L. Brown, Jr. secured a 
loan of the type of S. talpa Weber (1934, Psyche, 41 : 63- 
65, tig. 1) from the collections of the Illinois Natural 
History Survey. This specimen he very kindly placed 
at my disposal, since I had not seen it during earlier 
studies on Strumigenys in Ohio (Wesson and Wesson, 
1939, Psyche, 46 : 91-112, PI. 3). The type of talpa 
proves to be indistinguishable from paratypes of S. vena- 
trix which I had described from southern Ohio, and the 
latter name should be dropped. 
According to Brown’s recent revision of the dacetine 
genera, 8. talpa should be transferred from the genus 
Strumigenys Fred. Smith to the genus Smithistruma 
Brown (1948, Trans. Amer. Ent. Soc. 74 : 101-129, 2 figs.).
