266 THE CANADIAN ENTOMOLOGIST. 



was taken by Mr. Evans, at Evansville. As he thought it to be a short- 

 bodied form of S. Carolina, he has no recollection of the exact date or 

 place in which it was found. 



Acanthosoma cruciata, Say. 



Mention of this handsome member of the family Pentatomidse occurs 

 in but few of the published lists of Heteroptera. This is probably not so 

 much due to its scarcity as to an ignorance of its food-plant and habitat. 

 In Indiana I have found it in abundance on several occasions, but always 

 on the leaves and stems of Spikenard {Aralia racemosa, L.), growing on 

 the sides of deep damp ravines. The mature insect may be taken during 

 August and September. 



Trichopepla setnivittata, Say. 



This is another uncommon Pentatomid, which appears to have a 

 special food-plant. I have taken it but once, Sept. 9th, 1894, in Vigo 

 Co., Ind., where I found it very common in all stages, on the heads, and 

 in the angles of the leaves, of the plant known as Rattlesnake-Master, or 

 Button Snake-root {Eryngium yucccefolium, Michx.). The insect will 

 probably be found wherever this plant abounds. 



Libythea Bachmani, Kirtland. 



This Httle butterfly, so readily known by its long, beaklike palpi 

 and angled fore wings, is usually of rare occurrence in Indiana. This 

 season, however, it has been very common, and has been noted in a num- 

 ber of localities in the State. On June 14th, eighteen specimens were 

 secured from the flowers of some bass wood trees {Tilia americafia, L.), 

 which stand in front of my residence, in a thickly settled portion of the 

 City of Indianapolis. 



Papilio philenor, L. 



This butterfly is very common in Indiana, and for a long time I was 

 puzzled as to its food-plant, the ones commonly mentioned in the books, 

 Aristolochia serpe?itaria, L., and A. sipho, L'Her, being very rare in the 

 State. The problem was solved one day, however, when I found the 

 larvpe of philenor feeding upon the leaves of the wild ginger (Asarum 

 Catiadense, L.), a common plant along the rich hillsides of Central and 

 Southern Indiana, and one which belongs to the same family as the differ- 

 ent species of Aristolochia.
