 unstriped thorax, yellow scutellum and smaller size. 



L. lineola is ratlier common liere and it is known from almost 

 all parts of Denmark ; it occurs not so early as the preceding species,

 meadovvs in low herbage and on bushes, but also in woods on stems 

 of trees. It is not rarely found beset with developmental forms of a 

 Trombidium, I once look it in great numbers on stems of spruce fir 

 in Charlottenlund, all individuak highly infested with the Trombidium;
