The superiority of this form of case for butterflies will be readily 

 perceived, as the upper and under surface of the wings can be 

 seen by simply turning the drawer without touching the insect, 

 and there is no danger of breaking or injuring specimens. The 

 cost of the case is no greater than if made in the old style. 



COLLECTING IN THE WILDS OF PENNSYLVANIA. 



BY CHARLES A. BLAKE. 



During the latter part of last July, being up in Tioga County 

 and having a day to spare, I concluded to try that section ento- 

 mologically, so, early in the morning, got my traps together and 

 found a native who agreed to take me in his buggy, in which we 

 rode to a wild spot not far from Niles Valley, and about the 

 roughest ride I ever experienced. We halted close to a deep 

 ravine which looked promising, and climbing down among the 

 rocks, which here are of gigantic proportions, began my survey. 

 The rock formation I thought belonged to the Laurerifsaxv group, 

 but not being geologist enough to determine that point with cer- 

 tainty, mentioned it to Prof Heilprin on my return, who soon 

 satisfied me that my speculations were wrong. 



Passing through the ravine I came upon a beautiful little valley, 

 which the before-riientioned native said was called Martm dale^ on 

 account of the vast number of swallows that congregate there, 

 and from appearances should judge it was a paradise for the 

 botanist. At the northern end there was a small sheet of water 

 called QXmb Lake, where I captured several species of hymenop- 

 tera among the v^^Xoxcress on the shore. Not far from the edge 

 of the water I noticed a snake-.r^/« w<?rvously twitching, and on 

 investigating matters, found it contained several specimens of 

 Necrophorus americana, Silpha americana and a species of Der- 

 mestes, which I bottled. Among the debris on the shore was a 

 curious specimen of Xyloryctes satyrus, in which the horn was 

 curved forward, but I unfortunately lost it. 



In a dense wood on the opposite side of the lake there were 

 ant hills and ants enough to satisfy even Dr. McCook had he been 

 there. While examining the trees for Catocalae five or six species 

 occurred, among them C. relicta. In this wood I noticed a large 

 number of Libellulidae, apparently flying around a blue/'oy wasting 

 in a tall Pine tree, and I nearly dislocated my cervi^ra/ f^r/ebrae
