 Sacken has recorded the very singular fact, that in old, 

 but not in recent specimens, the two sexes sometimes 

 diftcr considerably in their color. (/'/--«-, JCnl. .V",-., P/n'l..

 nious gall. 



Cabbag-e pests—Jokii A. WiUiums, HurrmhJmrg. 

 A//.— The elongate cylindrical mahogany-colored horny 

 worms, about % inch long, which you .state to -'feed on 

 the roots of the. cabbage, sometimes destroying the en- 

 tire crop," are the lar\a of .some .species of Click- 

 %eetle (Elater family). From their shape and hard- 

 ness, these larvie arc called " Wire -worms." We 

 cannot determine the particular species, as, from 

 the fact of this family remaining many years In 

 the larva state, but very few Indeed have been 

 bred to maturity. In all probability your species 

 feeds, ifot exclusively upon cabbage, but gener- 

 ally upon all garden crops. We have several such 

 species in the North, but lluy all differ from yours. 

 Alderman Jlechi, one of ili. m.i-i m iriitifie farmers in 

 England, claims to ha\e de^irowil tin- wireworms in 

 his fields for many sucee.s.si\c \cai.s by sowing salt at 

 the rate oi about six bushels per acre, just as the small 

 grain was coming up. The Flea-beetle which you state 

 to "prey on the leaf of the young cabbage -plant," Is 

 the same wavy-striped Flea-beetle which you will find 

 figured and iUustrated in A. E. , pp. 15.S-9. 



Bug^s g^atbering- on Pear Sboots — H. J. Ayres, 

 Villa Ridge, 111. — The black shiny insects, about one- 

 jtenth of an inch long, which you " at first noticed 

 swarming on the ground and collecting on the ends of 

 the Rosin-weed" but which have lately "collected in 

 great numbers on the shoots of the young peai- trees," 

 are the same Flea-like Corimeliena ( Oorimelxnapulicana , 

 Germ.), spoken of on page '207 in answer to Jiio. M. 

 Pearson. 



Potato-bng— ./^. />'. GaHwell, Wilhinsomille , Mass. 

 —The Potato-bugs which you have '- frequently found 

 feeding on the leaves of Potatoes and Tomatoes, but 

 not in sufficient numbers to be seriously injurious," 

 are the same .species of Tortoise-beetle ( (7a»«?y« duvata) 

 rcfcrn^d to in our last No. (p. -228), as found on potatoes 

 iiofh in New York and in Massachusetts.
