by the expanded flavescent lateral margins of the elytra, 

 the tostaceotis antennie, the less developed apical joint of 

 the maxillary pal|)i ill (^,and the paler le;;s. The t^enoral 

 shape is very similar in the two sexes, as in S.furmicarius and 

 S. collaris, which are larger insects. The resemhlance to a 

 Scydmrenid, a3 well as to an ant, is nither striking in the 

 present s|)eeies.
