From llvldlpennes , to v/hich it is closely allied, vittata is without 

 difficulty separated by narrower form, shorter antennae, and longer, more

It is found namely in company with the black ant, Lagius fuli^inosus , 



where it of|en can be taken in great numbers at the anthills; more rarely 



and singly is it encountered at bumblebee nests end at outflowing treesap.
