NEW YORK STATE MUSEUM 



collections of many species new to the herbarium have been 

 secured. In most cases the species are represented by both flow- 

 ering and fruiting specimens. 



The services of Mr Stewart H. Burnham, as temporary assist- 

 ant, were secured from July I to Sep. 21. He was employed in 

 making a general rearrangement of the books and pamphlets of 

 the library and of the duplicates and extralimital specimens of 

 the herbarium, and in other general museum duties. 



ENTOMOLOGY 



Mosquitos. The state entomologist reports that the season of 

 1904 has been comparatively free from insect injury to agricul- 

 tural crops and consequently he has given considerable time to 

 investigating our mosquito fauna. Over 50 species have been 

 found in the State, and the results of this work have been em- 

 bodied in a bulletin, illustrated by over 300 original drawings or 

 photomicrographs, giving the life history and describing the 

 immature stages of over 40 species and characterizing 12 as 

 new. 



San Jose scale. The investigations of methods for controlling 

 the San Jose scale, Aspidiotus perniciosus Comst., 

 have been continued and a number of experiments with various 

 washes conducted in a scale-infested orchard at Warwick with 

 gratifying results. The efficacy of natural enemies in con- 

 trolling this serious pest, has been further tested by liberating a 

 third instalment of beneficial Chinese lady beetles, C h i 1 o - 

 cor us similis Rossi, in an infested orchard at Kinderhook. 



Grape root worm. The work of 1902-3 on the grape root worm, 

 Fidia viticida Walsh, in Chautauqua county vineyards, 

 has been continued and valuable data as to the efficacy of ar- 

 senical poisons for the control of this species, secured. 



Aquatic insects. Investigations of aquatic insects, started in 

 1900, have been continued and Dr James G. Needham of Lake 

 Forest University, is engaged upon a monographic account of our 

 stone flies or Plecoptera. 



Leaf-hoppers. The office has been fortunate in securing Prof. 

 Herbert Osborn of Columbus O., a well known specialist on leaf- 

 hoppers or Jassidae, to do some special collecting in the State 

 and the result of his work will be given in detail in his report. 



Hemiptera. Mr E. P. Van Duzee of Buffalo, a skilful collector 

 and well known authority on Hemiptera, has also collected in the
