The Pennsylvania specimen was taken along the Castleman 

 River, near a very swift ripple about a mile above Rockwood. 

 It was resting on a large boulder at the water's edge. As I 

 approached it flew away. Half an hour later, when I again 

 visited the spot, it (presumably the same one) was resting on 

 the identical rock where I had seen it before. It was the only 

 one of the species observed. The ground color of the thorax 

 was a beautiful dark grass green. About the ripple where it 

 was found, Gomphus brevis and G. albistylus were common.

 and peculiar fauna is enough to draw Pennsylvanians from 

 their native heath and make them forget that there are insects 

 in their own State. It is only necesary to go eight or twelve 

 miles from Philadelphia to find excellent places to work in 

 with the net. This part of the State abounds in barren areas 

 which afford no temptation to the grasping agriculturalist, and 

 have consequently lapsed into grand reserves, blessed with an 

 absence of fences and trespass signs, a delight for the free. 

 The flora is rich, as varied and peculiar as the insect world, 

 which in great part it supplies. Here we find endless variety 

 of land, woods, bogs, wastes, clearings, each of which affords 

 some specialties in the entomological line. Sand clearings with 

 a few scattered plants, here and there a short pine tree, form 

 the asylums of Fossorial Hymenoptera and yield fine things to 

 the one who hunts. 



Near to the Delaware and Big Timber Creek, here a county 

 boundry, in the corner of Gloucester County, is such a sandy
