from various localities, especially Missouri and Texas, of E. bassettella 

 parasitising Kermes petliti, Ehrh., and K. galUformis, Eiley, infesting 

 several species of Quercus. All the early stages of the parasite, which 

 are described, are spent in the body of the host. The larva, before 

 pupating, cuts a hole in the hard wall, which is then closed firmly 

 with tough silken threads, and through this the adult ultimately 

 emerges. Descriptions of the adult and larva are given. E. bassettella 

 appears to have only one annual generation, and is undoubtedly more 

 widely distributed than its records show ; in a few cases it has been 

 abundant enough materially to reduce the numbers of the Cocpid. 



Feeris (G. F.). Two Species of Phylloxera from California (Hemiptera ; 

 Aphidae).— ^'ntom. News, Philadelphia, Pa., xxx, no. 4, April 

 1919, pp. 103-105, 2 figs. 



Only two species of Phylloxera have hitherto been recorded from 

 California, P. popularia, Perg., on poplars, and P. salicola, Perg., on 

 willow. To these are now added Phylloxera stanfordiana, sp. n., on 

 oak {Quercus douglasi). Some notes are also given on a species doubt- 

 fully identified with P. salicola, Perg., found exposed on the bark 

 of Populus trichocarpa and Salix sp. in California and on Popidus 

 candicans in Utah. 



MuiR (F.). The Use of Insecticides against Leaf hoppers.— Hawauan 

 Planters Record Honolulu, xx, no. 3, March 1919, pp. 171-172. 



As natural enemies destroy 90 per cent, of sugar-cane leaf -hoppers 

 [Perkinsiella saccharicida], it has been suggested that the remaining 

 10 per cent, should be eradicated by means of insecticides. The 

 author considers this a mistake until every possible use has been 

 made of natural enemies. Insecticides would not only destroy the 

 leaf-hoppers, but also greatly reduce the number of parasites, thus 

 allowing the surviving leaf-hoppers every chance of increase.

This bulletin contams the usual information concerning plant pests 

 and the best methods for their control, with a diagram showing which

 Special tables are given for spraying apples, peaches, and pecan 

 nuts and for dusting peaches in Georgia.
