^sS'To Subscribers in Canada. — Rev. Charles J. S. Be- 

 THUSE. (Secretary of the Entomological Society of Can- 

 ada,) Credit, C. W., has very kindly undertaken to for- 

 ward to their respective destinations all such copies of 

 the Practical Entomologist as may be subscribed for 

 through him by gentlemen residing in Canada. Those 

 desirous of subscribing in this manner will please send 

 him their name and address, together with sirrty-two cents 

 for each copy they desire to take, na.me\y, _fi/ly cents for 

 the regular subscription money and twelve cents for the 

 amount of the Canadian postage that has to be prepaid. 

 By this arrangement they will save the ten cents postage 

 required to write directly to the Society at Philadelphia, 

 U. S., less the two cents postage to Cobourg, 0. W., and 

 they will also save the difference between the Canadian 

 and the International postage, which is twelve cents; 

 making a total saving for each year of twenty cents. 



.^3"The V. S. Postage on the PRACTICAL ENTOMOLO- 

 GIST is 12 cents jier year, or 3 cents per quarter, paya- 

 ble in advatire, at the Post Office of the Subscriber. 



_;0^INDEX TO VOLUME 1.— At the time No. 12, of 

 Vol. 1 of the Practical Entomologist was printed, it had 

 not been decided whether to close the Volume with that 

 number, or to continue it to the end of the second year; 

 under those circumstances our Index and Title were not 

 issued. But having since concluded to commence a new 

 volume with the second years' issue, an Index and Title 

 page to Volume 1 have been printed, and will be furnish- 

 ed to those wishing a copy. 



NOTICE. 



^;S- We are compelled to discontinue the Practical 

 Entomologist to several subscribers who have failed up 

 to this day to remit their subscription money. This is 

 probably a mere oversight on their part; but labor and 

 materials are too high, and our terms are too low, for us 

 Bend the Practical Entomologist to any one on credit.

The TRUE THEIPS and the BOGUS THEIPS. 



Throughout the Valley of the Mississippi, vine- 

 growers and others in their Horticultural Meetings 

 are perpetually speaking of the "Thrips," as an in- 

 sect very destructive to the grape-vine. Some of 

 them, indeed, occasionally call it a "Thrip," erro- 

 neously supposing that "Thrip" is the singular form 

 and "Thrips" the plural form of one and the same 

 noun ; just as young beginners will sometimes talk 

 of a "specie" of insects, supposing "specie" to be 

 the singular and "species" the plural; and just as 

 I once heard an indignant Irishman exclaim — 

 "Faith, now, Judy, and you are a disgrace to your 

 'seek' entirely" — Paddy supposing that "seek" was 

 the singular form and "sex" the plural. What 

 particular species of insect is thus designated by 

 Western Horticulturists, and even to what Order 

 of Insects it belongs, is still a profound mystery to 

 the Entomological world. I have, time and again, 

 in the columns of the Practical Entomologist, 

 requested vine-growers to send me specimens, in 

 order that the enigma might be solved. But no 

 one has yet taken the trouble to comply with my 

 request. Since, therefore, the mountain will not 

 come to Mahomet, Mahomet must go to the moun- 

 tain. Since the vine-growers will not explain to 

 me what they mean by a "Thrips," I will .show 

 them pictures of two very distinct species of insects, 

 one or other of which has probably been mistaken 

 by them for a true "Thrips ;" and I will also show 

 them a picture of a true "Thrips," that they may 

 see how very diiFerent it is from any insect that 

 really infests the Grape-vine. 



Centuries ago, when Catholic Bishops sometimes 

 went into the army, like the notorious Bishop Polk 

 of confederate memory, a certain holy Bishop had 

 been taken prisoner on the field of battle by a King 

 of England. Forthwith the Pope of Rome demand- 

 ed, that his dear son in God should be released 

 without price and without ransom. By way of 

 practical answer, the King sent to the Pope the 

 blood-stained cuirass of the Prelate, with the puz- 

 zling question — "Judge thou, if this be thy son's
