THE lOUNG NATURALIST. 



Sugar at Hartlepool. — I sugared some 

 posts and rails on the Sand-hills on Friday 

 night, 28th July. There was scarcely a 

 breath of wind, and a heavy dew falling. 

 The low land on the west of the railway was 

 covered with dense white mist making it 

 appear as if covered with water. It was 

 exceedingly " close," and I thought a good 

 night for sugar, but scarcely anything visi- 

 ted it. Polyodon and pronuba were scarce, 

 and such species as p alien and impura only 

 appeared singly. A week before, these 

 species were shouldering each other out of 

 the way, and many others were equally 

 abundant. The best thing I got was a 

 female cytherea, which has laid me a lot of 

 eggs. I turned in -disappointment from 

 sugar to ragwort. Nothing upon it but 

 cubicularis, which has been abundant at 

 everything for at least two months. Tritici, 

 which is just out and fine, was scarcely ob- 

 tainable, and exceipt pronuba, and one or two 

 M. literosa, I saw nothing else but one N . 

 baja. I understand from Mr. Gardner that 

 he took N. mvida at sugar the same night. 

 Ravida was never common here, and I have 

 not heard of a capture for several years.

ECONOMIC ENTOMOLOGY. 



By S. L. Mosley. 



IV. Insects injurious to Window 

 and Greenhouse Plants. 



Aphis. — The Aphis, or Green Fly is a 

 great pest on many kinds of plants, and its 

 prodigious powers of increase makes it very 

 troublesome to get rid of. Rose-buds are 

 particularly liable to be infested by it, and 

 almost every kind of plant is more or less 

 subject to its attacks. 



Remedies. -Nature has provided a remedy 

 in the whole tribe of Lady-bird beetles 

 {Coccinella) . Both the beetles and the larvae 

 which produce them live upon these plant 

 lice, and if a few can be caught and placed 

 upon an infested tree they will soon clear it. 

 The larvae of the Hawk-flies {Syvphiis), and 

 Lace-winged flies {Chrysopa), also live upon 

 plant lice, and should be encouraged. Arti- 

 ficial remedies are syrnging with tobacco 

 water, warm soft soap water, or dusting 

 with powdered sulphur. Small plants may 

 may be taken up and rinced in tobacco and 

 soft soap water, as hot as the hand can bear, 

 finish with cold clean water and re-plant. 



Scale Insect. — This insects attacks 

 the vine. The female is in the form of a 

 scale, firmly attached to the stem of the 

 plant. The male has four wings. The in- 

 sect injures the plant by sucking the juices. 



Remedies. — Washing and brushing with 

 a hot application of soft soap and water, or 

 painting the stems with a thick coating of 

 paint composed of clay, soot, sulphur, and 

 water.
