ing in open spaces between clumps of wild cranberries. They were 

 all adults and no traces of the larvse could be found. The Illinois 

 record suggests that this species also will be found in suitable situa- 

 tions in Iowa when more collecting is done. 



Lcpyronia gibbosa Ball. This species was described from the sand 

 hills of northwestern Nebraska. The writer took it in eastern 

 Colorado and western Nebraska. In all cases it was taken from very 

 sandy areas and was next reported from sand dunes along the 

 Mississippi in Illinois by Hart and later it was found in similar sit- 

 uations along the coast in Massachusetts. Last season the writer 

 took this species quite commonly in sand hills along Wisconsin 

 river. From these records it seems certain that this species will be 

 found in sandy areas in this state.* It is probable that the larvae 

 of this species when found will prove to be subterranean, like that 

 of Philaronia abjccfa and Aphrophora pcrnmtata, as it is doubtful 

 whether it could maintain a froth above ground in such locations. 



Philaronia bilineata Say. This is an abundant species in the 

 Rocky mountain region. The writer reported collecting it in north- 

 western Iowa in the former paper and suggested that as the limit of 

 its range in the state. It has been found to be common in the north- 

 ern Appalachians and to extend across the United States in the 

 northern tier of states, coming down into Wisconsin to about the 

 Iowa line. Careful collecting will undoubtedly show that it extends 

 across our northern border. The writer has taken them by hundreds 

 in low, slightly alkaline meadows in Wyoming, but was not able to 

 find a sign of froth or a larva. It will probably be found to have 

 a subterranean habit like the other representative of the genus. 



PJiilaronia bilineata var. rciicitla n. var. 



Resembling typical bilineata, but with the entire dorsal surface 

 pale smoky, set off by a narrow median line, all the elytral nervures. 

 especially emphasized on the reticulate ones, and the basal half of the 

 costal margin creamy white. 



Described from a pair from Kimball, Nebraska, collected by the 

 writer. 



Philaronia bilineata var. nigricans n. var. 

 Resembling bilineata, but with the whole dorsal surface dark 

 smoky brown with the white stripe along the costal margin in sharp 

 contrast. This stripe widens a little and curves inward just before
