EEPORT OF THE ENTOMOLOGIST. 123 



tive, however, in Slielby, Jeffersou, Jackson, and Pulaski Counties. 

 They were reported also in Highland County, Ohio. 



Mr. William E. Marine, of Green Castle, Missouri, writes to the Depart- 

 ment that he has discovered a remedy for the ravages of insects or bugs 

 upon plum-trees. He says : "I have been successful in the use of road- 

 dust and sulphur. To one bushel of road-dust I add five pounds of sul- 

 phur, and commence the use of this mixture about the time the petals 

 fall off, dashing in haudfuls among the young plums, morning and even- 

 ing, tvfo or three times a week, for the space of six weeks, or until the 

 plums have attained a sufficient growth for resistance to the operations 

 of the bug." 



The pea-bug {Bnichu^ pisl) troubled farmers in some parts of Davis 

 County, Utah, causing them to discontinue the planting of peas. 



In Mecklenburgh County, Virginia, tobacco-worms [Macrosila Caro- 

 lina) were less destructive than usual ; these grubs were destroyed by 

 hornets and yellow-jackets. 



Aphides or plant-lice have been found in the hops in Oneida County, 

 3S^ew York. In Bladen, Moore, and Perquimans Counties, North Caro- 

 lina, and in Marlborough County, South Carolina, this pest has been 

 annoying to the cotton-planter. 



Much harm was done by cabbage-worms in Luzerne Comity, Pennsyl- 

 vania, and Cecil County, Maryland. 



The canker-worm was destructive to apple trees in Middlesex County, 

 Massachusetts. 



Owing to the very imperfect description given, by some of our corre- 

 spondents, of the insects sent to this Department for examination and 

 identification, it is hoped that hereafter they will either describe them 

 more fully, or, what is much better, send specimens of the insects them- 

 selves by mail, so that the entomologist may be able to identify them. 

 Soft-bodied larvae may be sent alive in small tin or wooden boxes, with 

 some of the plants they feed upon inclosed ; or if dead, they may be 

 placed in vials of weak alcohol. All beetles, plant-bugs, and hard-bodied 

 insects may also be placed in alcohol, though the bottle must be pro- 

 tected from breakage if sent through the mail. Butterflies, moths, &c., 

 may be killed by a slight pinch on the thorax, and may then be sent 

 folded in envelope corners or triangular slips of paper. Where there 

 are a number of these papers they may be conveniently packed in tin 

 or small wooden boxes. All packages should be addressed to the Com- 

 missioner of Agriculture. 



It is also hoped that our correspondents will particularly mention 

 what remedies are used in their neighborhood, and with what success, 

 in destroying our most common noxious insects, such as the wheat-fly, 

 Hessian fly, chinch-bug, army-worm, Colorado potato-beetle, «&c. It 

 would also be well for southern planters to make a specialty of report- 

 ing the success they have met with in applying remedies for the de- 

 struction of the cotton-worm or fly, and the boll-worm, or if any means 

 whatever have been used in their neighborhood to destroy them, and 

 what they recommend. 



NOTES ON THE DIPTERA, WITH THEIR REMEDIES. 



The following remedies, to guard against the injuries caused by the 

 diptera, or two- winged flies, as well as for the destruction of the insects 

 themselves, have been selected with gTeat care from the works of our 

 best entomological authorities, from reliable agricultural correspond- 

 ents, and from experiments made in the Department. It will, however,
