given by Mr. C. L. Marlatt, Chairman of the Federal Horticultural 

 Board, in his report to the Secretary of Agriculture of September 30, 

 1918. 



Notwithstanding the falling off of importations of plants, dangerous 

 insects have continued to enter on nursery stock. As these pests are 

 listed in the Quarterly Letters of Information of the Federal Horticul- 

 tural Board, copies of which are available to all inspectors, it is only 

 necessary to refer to the insects which appear to have potentialities, 

 if they become established and widely distributed in this country. 



The pink bollworm (Pectinophora gossypieUa Saunders) has been 

 collected on two occasions in shipments of cotton from Brazil, In one 

 instance, some 1,992 bags of cotton arrived at New York in violation 

 of the cotton regulations, and, as a result, were returned to the port of 

 origin, where, according to the Department of State, the entire ship- 

 ment was destroyed by the Brazilian Government, on account of this 

 infestation. The second shipment, consisting of about a pound of 

 infested cotton seed, was sent to the Department of Agriculture, and, 

 after a thorough examination, destroyed by fire. The sorrel cutworm 

 {Acronycta rumicis L.), which was referred to in the last list of impor- 

 tant foreign insect pests, has again been collected, in the pupal stage, 

 on miscellaneous plants from France. From European literature, it 

 is apparent that this insect is an omnivorous feeder, and its entry into 

 and establishment in this country should be prevented, if possible. 



A shipment of rhododendrons from Holland was found to be lightly 

 infested with larvae of Chimahacche fagella Fab., an insect reported to 

 be injurious to the foliage of oak, beech, and birch in northern and 

 eastern Ireland. Judging from the available literature on this insect, 

 it is apparent that it is primarily a forest and shade-tree pest, and its 

 occurrence on rhododendrons may possibly be accidental; although at 

 the time of examination there was abundant evidence of foliage injury. 

 The larvse of the swan or gold-tail moth (Porthesia similis Fuessl) were 

 collected on Japanese maple from Holland and on Cerasus avium from 

 France consigned to Pennsylvania. One hundred and ninety-four 

 nests of the fruit-tree Pierid (Aporia craicegi L.) were collected by New 

 York state inspectors on several shipments of deciduous fruit tree 

 seedlings from France. The fruit tree Pierid is another European 

 insect which is known to be a general feeder, having thus far been 

 recorded as devouring the foliage of fruit trees, wild rosaceous plants, 

 and deciduous shade trees. 



The azalea leaf miner {Gracilaria zachrysa Mey.) has been taken on 

 eight shipments of azaleas from Holland. Nests of the brown-tail 

 moth {Euproctis chrysorrhora Linn.) were collected on ten shipments 

 of miscellaneous plants from France, and egg masses of the gipsy
