to think these names represent two species. Those having reticulaUim 

 are ahvays endeavoring to obtain typiciwi ; while those having the latter 

 are always seeking for the former, without either of them succeeding sat- 

 isfactorily. The hterature of the subject is, perhaps, answerable for the 

 confusion. The catalogue of the species of Caloptero7i (by Crotch) is 

 now erroneous and obsolete. Dr. Leconte, in his recent Synopsis (Trans. 

 Am. Ent. Soc, vol. 9, p. 63), corrects certain errors that occurred in his 

 former Synopsis (Jour. Acad. Nat. Sci., ser. 2, vol. i, p. 74). He now 

 makes terminale Say a species, and places typicum Newm. as a synonym 

 of retiadatum Fab., referring to these two names all the forms now known 

 east of the Rocky Mountains, regardless of the color of the thorax and 

 elytra — to reticulatufti, those having two elevated elytral costge ; and to 

 termiiiale, those with four. By reference to the foot note (ib. p. 63) it 

 will be seen that two unfortunate errors occur in the text at page 20, 

 which, if not observed, would lead to great confusion. 



7. Euderces pi?ii Oliv. Five times this has appeared on the lists of 

 some of the more accurate of my correspondents, and as many times, 

 instead, have I been sent Pseiiocerus supernotatjis Say. I could scarcely 

 account for this, and for the great demand for so common and so widely 

 distributed an insect as P. super?iotatus, till an appeal for the correctness 

 of the determination ///// was made to the Journal of the Acad. Nat. Sci., 

 ser. 2, V. 2, p. 158, the writer stating that Dr. Leconte had several years 

 ago so named his insect. Reference to the place cited shows that Dr. 

 Leconte then regarded the Callidimn pini Oliv. and the Clyhis snper- 

 notatus Say as one species, which he placed in the genus Psenocerus. 

 Subsequent investigation proved that pini (which had been unknown in 

 nature to Dr. Leconte) was different from supertioiatus, both as to species 

 and genus. The error was corrected in the books, but it has given rise to 

 a great mistake in the tradition of the insect. . I have not yet seen pini, 

 but from the description of Dr. Leconte (Smithsonian Misc. Coll. 1873, 

 vol. xi., p. 202), it certainly resembles P. super not atiis. To distinguish 

 them at a glance, it is only necessary to remember that the thorax of the 

 former, instead of being pitted, is longitudinally rugose, and that there 

 is on the elytra anterior to the middle a smooth, ivory white, obliquely trans- 

 verse line which is wanting on the latter. E. pini seems rare. P. super- 

 notatus is one of the few Cerambycids that occasionally hybernate. In 

 February of the present year, I found three in the folds of a Cecropia 

 cocoon taken from some currant bushes.
