magnifying: Glassps l. a. FhA-, Diron, Ills.— 



For ordinary purposes we would recommend the com- 

 mon treble lens, mounted in a horn case, convenient 

 for carrying in the pocket. With this instrument, you 

 may use either one, two^ or aU three lenses together, 

 according to the magnitymg power required . If a still 

 higher power is required, a Stanhope lensmU be found 

 very useful; the only objection to it being that the 

 focus is so very short, that it requires to be used very 

 carefully withan'crf specimens, for fear of breaking their 

 legs and antennae. The Coddington lens has a longer 

 focus than the Stanhope, and magnities very nearly as 

 much, but the price of it is very high— about $10. All 

 kinds of lenses may be procured from Jas. W. Queen & 

 Co. , 924 Chestnut street, Philadelphia.

Grapes cut oft by the Tree Cricket — J. H. 



Tice, St. Louis, Mo. — You are quite right in supposing 

 that the tree cricket {(T.,;uitlius nieius) severs your 

 grapes from the bunclKs and snnii'tiines cuts oft an en- 

 tire bunch. We have cnuselves eaiight the httle ras- 

 cals at it, and have received speeinicns from B. L. 

 Kingsbury of Alton , 111., accompanied with the same 

 accusation. Other "hoppers," such as the so-called 

 Grasshoppers, and probably some of the Leaf-hoppers, 

 no doubt, share in this mischievous work, but until 

 we catch them in the act we must lay all the blame to 

 the Tree-cricket. The accompanying illustrations. 

 Fig. 30, representing the female, and Fig. 31 the 

 male, will enable 

 the grape grower 

 to recognize this 

 grape pruner. — 

 Though they have 

 been known to 

 "°' destroy plant-lice 



and thus ta some extent redeem 

 their character, we believe the 

 mischief greatly out-balances the 

 good which thev do , and therefore 

 advise their destruction. They 

 deposit their eggs in grape canes; 

 in raspberry and blackberry canes; 

 and in the twigs of a number of 

 trees and .shrubs, almost always 

 causing the death of th,. tui- i.r 



ous twigs of the white willow .which

them, from Uriah Bruner, of Omaha, Nebraska, with 



a statement that they had done much damage to this

 one-third of an inch long, and shaped a good deal like 

 a heeih-nut, save that they have asharp thorn, or horn,

 liorn ot an e.x or abufi'alo, are the Bufl'alo Tree-hopper 

 I ' ,,, '".''.ihis, Fabr.) This Tree-hopper is very com- 

 mon (ni a variety of trees, the sap of which it sucks with 

 its pointed beak; but, like aU the other true luigs, (or- 

 ders Beteroptera and Bomovta-a. to I he latter of which

 this writir in the second volume of Reports on Nomous 

 Jiisids. plate ii. fig. 4. The best remedy against the 

 dcjiredations of this little foe of yours is to catch him 

 and kill him . Something, however, may be effected by 

 destroying their eggs, which are laid in a short, curved 

 row, in a series of punctures made by the ovipositor of 

 the female in the bark and s,apwood. 



A Scavenger niistalccu for a Foe — Simmons <& 

 TilU,.,,. r;„e,/,n;/l..t.-:. .Sulphiiv Springs, jKb.— The large 

 balls ot I'artli and dung, measuring one and a half inches 

 in diameti'r, and lontaiiiing a large white grub with six 

 legs and a hninped and swollen back, are the dung-balls 

 of a lar^je hlaek dung-beetle known as c.pris .-ar^.i:,,.: . 

 During Ihe months of July and August these heetles 

 IVcaiinadlv lly into our rooms of an evening, with a 

 heavy Imzziiig lliglit. Y'ou say, "the sp. einieiis were 

 found ten incites" below the surface, imbedded in the 

 hard clay. They were five in number, m a row about 

 two inches apart . From its resemblance to the grape- 

 vine boi-er which has lately made its appearance, we 

 think it may be that larva in llie inqia slate," The' 

 pupa; of beetles may always la- di-iingiii-hed from lar- 

 vae by their incapacity to mo\e any oiler jiart but the 

 abdomen and by their liaving wing-sheaths. The balls 

 were placed where you found them by the parent bee- 

 tle, and similar ones are often to be found in the clay 

 ditches and clay banks around St. Louis. These bee- 

 tles are to be considered as beneficial rather than inju- 

 rious, as they simply clear away and bury offensive ex- 

 crement.
