REPORT OF STATE ENTOMOLOGIST, 1 898 249 



{Xylina not Nadata] (Schenectady daily union. July 8, 1898. p. 5, 

 col. 4 — 9 cm) 



Corrects the first reference to Nadata of the caterpillars devastating the maples and 

 states that they are either Xylina laticinerea or X. antennaia. There is but one brood 

 in a season. Spraying with paris green in the early spring is recommended.

Cucumber beetle — cabbage worms. (Country gentleman. July 14, 

 1898. d}^ : 546, col. 2 — 21 cm) 



Gives briefly the habits and life history of the striped cucumber beetle, Diabrotica 

 vittata Fabr., and recommends protecting the young plants with netting. Planting 

 of beans between the cucumbers, dusting the vines with land plaster, ashes or even 

 road dust are preventives of serious injury. Clean culture is advised. If the roots 

 are badly infested with the grubs, carbon bisulfid is the best remedy. 



Fresh hellebore, one ounce to three gallons of water, is recommended for the cab- 

 bage worm, Pieris rapae. Paris green may be used if the cabbages have not headed. 



Destructive rose bug. (Country gentleman. July 14, 1898. 63:546, 

 col. 3 — 20 cm) 



This insect, Macrodactylus subspinosus Fabr., is identified and its injuries in New 

 England and New Jersey mentioned. Its life history is briefly given. Paris green 

 or kerosene emulsion is usually not very satisfactory, owing to the beetle's resistance 

 to insecticides. Collecting the insects by some mechanical contrivance or protecting 

 plants by netting are the most satisfactory means of preventing serious injury. 



Hessian fly in Pennsylvania. (Country gentleman. July 14, 1898. ()2>' 

 546, 547, col. 4, I— 38cm) 



In response to an inquiry from Adams county, Pa., where this insect, Cecidomyia 

 destructor Say, has been very injurious, a general account of the species is given as 

 follows : Immense losses caused by it in New York and Ohio. Its life history. 

 Characteristics of an attack. Its parasites and their value. Its abundance another 

 season can not be forecast, as it may be injurious for a series of years. As prevent- 

 ives of injury, late planting supplemented by the early sowing of narrow strips to act 

 as decoys, thei burning of stubble and chaff, clean culture, rotation of crops and the 

 growing of resistant varieties of wheat, so far as possible, are recommended. 



Work of Xylina. (Country gentleman. July 14, 1898. 63 : 551, col. 2 



6 cm) 



Corrects the reference of this insect on page 491 of the current volume of the 

 Country gentleman, from Nadata to Xylina — it being either X. laticijicrea or X. 

 antennata. Its identity with the species seriously injuring apples last year is thus 

 rendered probable. A note is given of the defoHated soft maples along the Mohawk 

 river, presumably by this species.
