No experiments were made looking to checking the injuries of this 

 Nematode, and the various recommendations made are in general those 

 already given by Dr. Neal. They consist in the use of various alkaline 

 fertilizers, clean culture, and sterilization uf the soil by a system of ro- 

 tation which introduces crops not subject to their attacks. A German 

 method is given of trapping the worms with catch plants (" Fangen- 

 pflanzen"), which are dug up and destroyed after becoming infested and 

 before the worms have escaped. 



In the vicinity of Auburn, Ala., some 3fr species of plants were found 

 to be affected with Nematode root-galls. A list of the works consulted, 

 36 in number, is given, most of which are European. The text is ad- 

 mirably supplemented with six plates showing affected roots, entire and 

 in section, and the Nematode in its various stages. 



Economic Entomology in India.— We are glad to see that the high stand- 

 ard inaugurated in No. 1 of the " Notes on Indian Entomology," edito- 

 rially noticed in these pages a short time ago, is maintained in No. 2, 

 which has just been published by the trustees of the Indian Museum, 

 Calcutta. 



Mr. E. C. Cotes contributes a translation of an unpublished paper by 

 the late Dr. E. Becker on Trycolypa bombyeis, a new Tachinid fly, para- 

 sitic on Indian silk-worms (Bombyx fortunatus and Attacus ricini), and 

 figures larva, puparium, and imago. 



He follows with original notes on two girdling beetles, Gcelosterna 

 scabrata and Neocerambyx holosericeus. The former (allied to Oncideres 

 cingulatus Say) affect Sal saplings ; while Plocederus pedestris is found 

 boring in Sal and Jungham, and its lar^a forms a calcareous egg-like 

 case in which to pupate. A chrysomelid beetle, Aulacophora abdomi- 

 nalis G-. and H., is destructive to Cucurbitacece — similar to some of our 

 Diabroticas which also attack the Squash family. 



Papilio erithonius Cramer produces a caterpillar in appearance like 

 our orange dog, Papilio cresphontes, and like it is destructive to the 

 Orange. He says : 



In sending them Mr. Gollan notices that the insect does much damage to young 

 budded oranges, not a plant of which could be raised if boys were not kept to pick 

 off the caterpillars. 



A cut- worm, Agrotis suffusa (t), often does considerable injury to the 

 young opium poppy , while our well -kno wn Boll Worm , Eeliothis armigera, 

 is an established pest of the plant. Mr. Cotes says it was described by 

 Mr. John Scott, in his opium report, as Mamestra papaverorum. 



A brief note is given on Cecidomyia oryzce, a fly allied to our u Hes- 

 sian-fly," likely to become a serious pest to the rice plant. 



Article XI treats of Insecticides, and extracts from some experiments 

 with London purple, made by Mr. Gallan, superintendent of the Gov-
