the larger specimens of taurina are not very noticeable at first. 

 The slits of this Ceresa taurina Fitch were mistaken by him for 

 the crescent cuts of the Plum Curculio, while he very strangely 

 describes the eggs of what we know now belong to CEcanthus 

 niveus, or the Snowy Tree-cricket, as of the Ceresa bubalus. I 

 am familiar with various other kinds of small egg-punctures in the 

 twigs of various plants, undoubtedly of species belonging to the 

 Membracidae or Fulgoridae, but have reared and identified the 

 parent only in the case of Pceciloptera [ Orminis~\ pruinosa 

 Say and Enchenopa binotata 

 Say, the punctures of this last 

 being hidden with a white, waxy, 

 ribbed covering, which, as al 

 ready pointed out (Am. Nat., 

 xv, p. 574, July, 1881), was 

 referred by Fitch, in his col 

 lections, to Dorthesia. 



On referring to my scrap-books 

 and notes, it seems that the first 

 record of the oviposition of C. 

 bubalus was in a short reply to 

 a correspondent published by 

 Prof. Cyrus Thomas in the 

 Prairie Farmer of February 

 5, 1876, in which a brief descrip 

 tion is given of the nature of the 

 egg-punctures of an insect which 

 was identified as belonging to the 

 same family as C. bubalus, if 

 not to the same genus, but sup 

 posed to be distinct on account of 

 their difference from the punc 

 tures of bubalus as wrongly 

 determined by me. At the time 

 I had several notes of earlier date 

 on similar punctures, and having 

 submitted the drawings of them 

 to Prof. Thomas, he recognized his punctures as identical with those 

 now known to be of bubalus. My first specimens of these were 

 received Nov. 12, 1875, from Uriah McCall, Manchester, O., 

 who found them on Apple, Pear, and Quince. My notes 

 describe the punctures as follows: " Ordinarily there is a pair 

 of simple slits, the adjacent parts slightly swollen, each slit 

 leading to a row of, on an average, 10 eggs just under the 

 bark, the anterior or outer ends converging toward the middle. 

 The individual eggs are 1.3 mm. long by one-fourth as wide, pale
