 tarsi bilobed. Of the four species recognized by Casey, but one 

 has a known distribution ^vhich would bring it within the limits of 

 Indiana. This is 8. croceatus Casey. 8.7-4.5 mm. ni length, and 

 having the legs pale brownish-yellow, darker at the knees. Its 

 rangers given as New England to Nebraska, but no specimen has 

 as yet been taken in Indiana. 



Group III. 

 This group comprises species having the abdomen cylindrical, 

 without a margin along the sides and with the fourth joint of hind 

 tarsi simple. Three species may occur in the State, though but one 

 has as yet been taken.
