bases in trenches with a radius of about 3 feet and to a depth exposing 

 the roots. The small yellow ant, La sins inter jectus, Mayr, was noticed 

 tending and transporting these Aphids from place to place. Paradise 

 stocks seemed to have a considerable degree of immunity. Taeniothrips 

 'pyri, Daniel, (California pear thrips) w'as the most important insect 

 of the year in Maryland. It was discovered by Mr. W. M. Scott in 

 an orchard near Baltimore. It had previously been found only in 

 England, California and the Hudson River valley. Diabrotica 

 12- punctata, Oliv. (twelve-spotted cucuinber beetle) did considerable 

 injury to young peach foliage and buds. PJu/lloxera vastatrix, Planch. 

 (grape Phylloxera) were found infesting grape vines received from a 

 nursery. Scale-insects reported as doing local damage on fruits, 

 included : — Eulecanium [Lecanium) 7iigrofasciatum, Perg., on peach ; 

 Lepidosaphes nlmi, L., on Persian walnut ; and Pulvinaria vitis, L., 

 on grapes. Bean pests were very injurious ; Sitones hispidulus. F., 

 attacked newly-planted Lima beans, which also suffered injury from 

 Chortophila {Pegomyia) fusciceps, Zett. ; Ceratoma trif areata, Forst., 

 damaged wax beans. Lixus concavus, Say, (rhubarb weevil) was 

 abundant, but did no serious injury. Its native food-plant is dock, 

 and this weed should be eradicated from market-gardens. Mnrgantia 

 histrionica, Hahn, was reported from Salisbury as extremely injurious 

 to horse-radish, which was planted next to cabbage, the latter remaining 

 practically untouched by these bugs, which are a common cabbage 

 pest. The Eumolpid, Nodonota puncticoUis, Say, injured roses exten- 

 sively. The Arctiid, Diacrisia virqinica, F., and Chloridea ohsoleta, F., 

 did considerable damage to geraniums in greenhouses near Baltimore. 

 The greenhouse Orthezia [Orthezia insignis] badly infested Colias in 

 one of the parks in Baltimore ; Black Leaf 40 proved an efficient 

 control. Mining Dipterous larvae, probably Phgtomyza aquilpgiae, 

 Hardy, infested the leaves of hybrid Aquilegias on the Experiment 

 Station grounds. Psylln biixi, Reaum. (boxwood Psylla) injured box 

 at Baltimore. Shade-tree pests included : —Chrysomphalus obscurus, 

 Comst., and G. tenebricosus, Comst., on white oak and soft maple 

 respectively ; Palvinaria acericola, W. & R., Prociphilus tesseJlata, 

 Fitch, and Aleurochiion forbcsii, Ashm., on maple ; and Psylla (Trioza) 

 diospyri, Ashm., on persimmon. The caterpillars of Papilio ajax did 

 considerable injury to papaw foliage on young plants in the Experi- 

 ment Station nursery. The Hispid, Ch.alepus dorsalis, Thunb., and 

 GaUerucella luteola, Mull., continued to do considerable damage to

"When studying the life-history of Horistonotus vhleri in Colleton 

 County, S.C, in 1912 and 1913, Monocrepidius vespertimis, F. (spotted 

 .click beetle) was also found in great abundance. Since then it has 

 been observed in other parts of South Carohna. In Colleton County, 

 its larva was found associated with that of H. vhleri and is believed 

 to have been responsible for at least 45 per cent, of the damage formerly
