Ninth Report of the State Entomologist 44 5* 



A Thrips Attack on Cabbage. (Country Gentleman, for October 

 27, 1892, Ivii, p. 809, c. 2, 3 — 27 cm.) 



Cabbage and cauliflower leaves received from Kingston, Pa., abound with 

 a minute Thrips, the particular species of which can not be named: it is 

 probably an undescribed species, no attack of the kind having been previ- 

 ously reported. The number of genera and species of Thrips: their low 

 position among insects: referred to Thysanoptera: their general features: 

 carnivorous and herbivorous: food plants: the nature of injury to cabbage 

 and cauliflower by this species : pyrethrum will prevent injury by it. 



The Tischeria Apple-Leaf Miner. (Country Gentleman, foi^ 

 October 27, 1892, Ivii, p. 809, c. 3, 4 — 20 cm.) 



Reddened leaves from an orchard in Schenectady, N. Y., show the attack 

 of Tischeria malifoliella Clemens. The mines and the process of their 

 construction are described. They contain at this time the larva, which 

 hibernates in the leaves and transforms to the pupa and imago in the spring. 

 The remedy would be, collecting and burning the infested fallen leaves 

 during the autumn or winter. The insect extends over a large part of the 

 United States into Texas. It is rather local, and seldom, for reasons given, 

 proves particularly injurious. It occurs also on Cratcegus, blackberry, and 

 raspberry. 



Distribution of the Pear Psylla. (Country Gentleman, for 

 JSTovember 3, 1892, Ivii, p. 831, c. 2, 3 — 13 cm.) 



The probable introduction of Psylla pyricola at SaHsbury, Conn., in 1832, 

 is stated, together with its present known distribution. Request is made for 

 information of its occurrence in other locahties; and as aid in its recognition, 

 its features and mode of operating are stated. 



The Cow-Horn Fly in New York. (Country Gentleman, for 

 November 10, 1892, Ivii, p. 847, c. 1 — 10 cm.) 



The interest attaching to the spread of insect pests into new territory, 

 renders it desirable to ascertain the extent to which this fly has been dis- 

 tributed over the State of New York during the two and a half years that it 

 has been known therein. Of the sixty counties of the State, it has been 

 reported from twenty-eight. Information of its presence in any of the 

 other thirty-two counties (named) would be gratefully received by the State 

 Entomologist. 



Apple-Tree Bucculatrix. (Country Gentleman, for December 

 22, 1892, Ivii, p. 967, c. 2 — 8 cm.) 



Cocoons from. Clyde, N. Y., contain the pupae of Buculatrix pomifoliella 

 Clemens. The transformations of the insect and the remedies for it, are 

 named. •
