IS.oS. 75. 



Linear, slightly wedge-shaped. Color given in key; front and middle 

 legs partly dull yellow. Length 2.S-3.2 mm. 



Southern two-thirds of State; scarce. May 27-.June 21. The 

 Indiana specimens are of the \-:Hriety cervkalis Lec, and resemble 

 marginrdis Say very closely, differing only in having one less ridge 

 on hind tibise and first joint of tarsi. If these ridges and color of 

 thorax are variable, as some authorities claim, several of the forms 

 with black body and reddish head will have to be combined under 

 Say's name.
