whenever a small patch of grass lawn or road becomes unusually 

 moist it quickly becomes the starting point of an attack that may 

 spread over 600 feet in a few weeks. The cricket seems to be in- 

 capable of destroying really hard turf that is top-dressed with a heavy 

 layer of " tiff." Where the pest occurs in small patches on lawns, it 

 is easily checked by watering with whale-oil soap solution (1 lb. to 5 

 gals, of water). Large numbers of the crickets may be brought to the 

 surface in this way and collected. The advantage of this remedy is 

 that it is not necessary to fork the lawn before applying the solution.

Among the new flies described is Rhagolelis juglandis, from Arizona, 

 where it was found mining the exocarp of Juglans regia. It appears 

 towards the end of June and oviposits in the green husk of a variety 

 of the Enghsh walnut, which is mined by the larvae, with the result 

 that the nut turns black. The earlier larvae descend by a silli thread 

 to the ground for pupation, but most of them stay in the husk till 

 the nut falls, and pupate in it.

The present situation with regard to the pink boUworm [Platyedra 

 gossypiella] in the Southern United States is reviewed. A feature of 

 the work has been the tracing of all possible means of dissemination 

 of the pest throughout the cotton-growing area, and repeated 

 inspections of the cotton-fields. No new infestation, and only one 

 re- infestation of old territory, was discovered, and energetic measures 

 were at once taken to suppress this outbreak. The survey work on 

 the Mexican border has been continued as well as research work at
