 the National Museum are from the Kiley collection. 



Dr. J. A. Allen found the insect in Iowa only in dry prairies on the 

 grass, excepting that the least-marked specimens occurred in groves, 

 and there only. 



Occasionally a specimen, and especially a female, is found in which 

 there is no trace of ferruginous on the tegmina, which are then green 

 with a pallid stripe along the dividing line between the discoidal and 

 anal areas, reminding one of H. riridis or H.festivus. * 



The specimen above referred to from Orizaba, a female, differs 

 slightly in its somewhat abbreviated tegmina, and the mottled mark- 

 ings of pallid yellow and green upon the lateral lobes of the prono- 

 tum; it possibly indicates another species.
