The resemblances of certaindifferent species are so close that naturalists have often ignoredtheir distinguishing characters. In Blatchleys work on TheOrthoptera of Indiana will be found the most reliableinformation regarding our species. Some crickets are saidto be cannibalistic, and will not hesitate to devour members oftheir own species. I once found evidence of the ravenous appetites of cricketsduring an excursion afield. I came upon a dead shrew-mole,during September, lying on the ground, which had evidentlybeen killed but a short time previously. Four or five largeblack crickets, Gryllus abbreviatus, were eating voraciouslyfrom the shoulder and abdomen of this little mammal. Uponclose examination, I found a fresh cavity in the side of the body,from which the flesh had been cleanly eaten from the scapulaand vertebrae between the shoulders. I surmised that possiblythe crickets were responsible for the death of the mole. 388 NATURE SKETCHES EST TEMPERATE AMERICA. Katydids in their Night Resorts ^IT^H the light of my lantern, I frequently\\ flL%^ found katydids in the taller herbage along^ V V roadsides and fence rows. No one canimagine, without personal experience, the beauty of the viewpresented as the lantern light fell upon the profusion ofgreen herbage. Here and there, for instance, the view may beenlivened by either the little slender green grasshoppers,Xiphidium, on the very summit of a head of timothy, or thepresence of a cone-head, or the exquisite oblong-winged katydidperched on the goldenrod. After a little attention is given tothe notes of the males, the various species can be distinguished,and then one may trace them to each of the musicians. Onenight, near the last of July, I started upon a katydid excur-sion along a narrow lane. A farmer had mowed
