THE PRACTICAL ENTOMOLOGIST. 



121 



J. Y. Smith, Wise. — From your description, your worms 

 seem to have been similar to tliose seen by Mr. Hoge ; 

 (see above ;) but as you do not even send dead and dried 

 up speoirriens, I cannot be certain. 



S. K. 'WilUams, Kentucky. — Your statement that "to- 

 •wards the end of June, 1867, you have destroyed several 

 nests of the Tent-ca,lerpiUa,T [Clisiocampa a7iiericana) on 

 your pear-trees," and that "two or three summers ago you 

 had your pear crop greatly injured by them," is very in- 

 teresting. On pear-trees, however, the occurrence of tins 

 insect is certainly rare and exceptional. As to your find- 

 ing the Tent-caterpillar of the Forest (CI. sylvatica) only 

 on Black Walnut (Juglans nigra), see my Article on "The 

 three so-called Army-worms." 



A. H.Mills, Vt. — The larvee now infesting yourcurrant- 

 bushes are the terrible Imported Gooseberry Sawfly, (A'e- 

 matus ventrico.^us), respecting which see my Paper in the 

 last number of the first Volume of the Practical Ento- 

 mologist. "The common yellow worm with black dots," 

 that formerly infested your Currant leaves, was probably 

 the common Spanworm of the Currant (Ellopia ribearia) ; 

 and the "very small green one" was perhaps my Native 

 Gooseberry Sawfly (Pristiphora grossvjarice), an account 

 of which you will find in the paper referred to above. 



Dr. Wm. Maus, 111. — The new enemy of the Colorado 

 Potato Bug, which you saw "destroying the larva, and so 

 intent on its prey as to retain its hold even when you 

 gathered the leaf on which it stood," is, I believe, the Le- 

 bia grandis of Hentz. This beetle is one of the vast group 

 of Ground Beetles {Car'abu.1 family), almost all of which 

 are cannibals; but the genus to which it belongs, unlike 

 most of the other Ground-beetles, haunts plants and is 

 active by day, instead of living on the ground and being 

 nocturnal in its habits. That others as well as yourself 

 may recognize this species, I may here state that it is J 

 inch long, with the head and thorax red and the wing- 

 cases bright blue. The larger olive-green insect, about J 

 inch long, that preyed on the larva of the Potato Bug 

 last year, is a True Bug (Order Heteroptera) belonging to 

 the genus Rhaphigaster in the Scutellera family. It is a 

 very common species, and I have noticed it transfixing 

 with its beak a wild hee i inch long appertaining to the 

 genus Andrena; so that it seems to be rather a general 

 feeder. This species, so far as I am aware, is undescrib- 

 ed. Other observers have noticed Bugs, belonging to this 

 same family and probably to the same species, destroying 

 the larvjB of the Potato Bug. Like all the rest of the Scii- 

 te/lera family, it emits when disturbed the peculiar odor 

 of the Bed-bug and the Chinch-bug. — The leaf that you 

 send bears on its surface the eggs of a Golden-eyed Fly 

 (Chri/sopa). You will find a figure of these eggs in my 

 Article on Plant-lice. (Practical Entomologist II, p. 42.) 

 — The Ladybird that your friend found among the Plant- 

 lice on his Cherry-tree, is the Fifteen-dotted Ladybird 

 (Myzia lb -punctata) — one of the few species found promis- 

 cuously in Europe and America. 



Fred. Blanchard, Mass. — I cannot identify the large 

 Prionus found in wool waste. It is most probably, as you 

 suggest, an exotic species. 



Tipton & Melliott, Ohio. — See Answers to M. S. Hill, in 

 Practical Entomologist, Vol. I, p. 46. and to Thos. C. 

 Wright, Vol. II, p. 8. 



The Colorado Potato Bug. 



I find the following in the Monthly Report of 

 the Agricultural Bureau for September, 1866, p. 

 344: 



Indiana County^ Pennsylvania, — " Potatoes are being 

 somewhat injured by the' bugs." [Probably the ten-lined 

 spearman, Doryphora \^-lintata.'\ 



Mr. Glover must, I think, be in error here. The 

 New Potato Bug cannot have yet reached Pennsyl- 

 vania, though in eight or ten years' time from now 

 the inhabitants of that State will probably be con- 

 templating, with admiration, its beautiful rose-color- 

 ed wings and striped wing-cases, as it flies into their 

 potato-fields, looking as innocent as one of these lit- 

 tle anjrels in crinoline. B. D. w 



PUBLISHERS NOTICE. 



This number, or rather two numbers in one, closes the 

 second and last volume of the Practical E.ntomologist. 

 The reason of its discontinuance hag already been given 

 on page 104. At some future time, when there is enough 

 interest taken by the Agricultural Community in the 

 subject of Economic Entomology, to Warrant the support 

 of a journal of this kind, the publication of the Paper may 

 be resumed. 



Our thanks are due to many kind gentlemen for their 

 valuable aid, but especially to Benj. D. Walsh for the 

 faithful and handsome manner in which he has filled the 

 Editorial Chair — a task which, we believe, could not have 

 been so well performed by any other individual in 

 America. 



To the Agricultural Press in general, our thanks are 

 also due for the many liberal notices given of our little 

 Paper. Not having the money to advertise extensively 

 in papers of large circulation, the existence of the Prac- 

 tical Entomologist has been made known almost entire- 

 ly through the liberality of the Agricultural Press. 



In the publication of the two volumes of the Practical 

 Entomologist, the expenses have considerably exceeded 

 the receipts ; and in order to balance the accounts as 

 nearly as possible, we shall have copies of Vols. I and II 

 neatly bound together in one volume, with full index, 

 Ac, which we shall offer at the low price of $2.25; or un- 

 bound for $1.25. We hope that our friends will do all 

 they can to induce their neighbors to send for a copy of 

 this work — which should be in the possession of every 

 Cultivator of the Soil — and thereby help us to pay our- 

 selves back at least a portion of what we have lost in its 

 publication.
