 Orizaba, ]Mexi(M>, January (L. Bruner). Nearly all the speeimeus frcuii 

 the National Museum are from the Piley eolleetion. 



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

 grass, ex('ei)ting that the least-marked specimens occurred in groves, 

 and there only. 



Occasionally a specimen, and esi)ecially 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 discoidul and 

 anal areas, reminding one of //. ri rid is or H./vstinis. 



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 i)rono 

 tum; it possibly indicates another s})ecies.
