NOTES FOR THE YEAR 



Two rare scale insects were found the past season. The first was 

 the inconspicuous Aspidiotus osborni New. & Ckll. on 

 white oak at Scarborough. It has not been previously recorded 

 from the State. The second was Pulvinaria acericola 

 Walsh on flowering Cornell, Corn us florida,at Tarrytown. 

 Both species were relatively abundant on their respective food plants, 

 though apparently causing no material injury. Another scale insect 

 worthy of mention is the Pseudococcus ledi Ckll., which 

 was found abundant upon Ledum by Prof. C. H. Peck at West 

 Sand Lake, N. Y. 



The peculiar regal 

 rose gall, R h o d i t e s 

 gracilis Ashm., was 

 received September 13th 

 from Mrs E. P. Gard- 

 ner, Canandaigua, who 

 'found it in numbers on 

 Rosa blanda. This 

 is not only a new species 

 for the State, but ap- 

 pears to be the first pre- 

 cise locality and food 

 plant record for the 

 species.^ Another inter- 

 esting though extralim- 

 ital insect gall, that of 

 Dryocosmus favus 

 Beutm., has been identified in the collection. It was found by 

 Mr W. H. Leivelsperger at Fleetwood, Pa., August 26, 1908. 



The balsam plant louse, Mindarus abietinus Koch., 

 has been unusually abundant and injurious in a number of Adiron- 

 dack localities. The spruce gall aphid, Chermes abietis 

 Linn., is very prevalent and frequently seriously deforms infested 

 trees. A related gall insect, Chermes floccus- Patch, was 

 received August 23d from Mr John Nill of Star Lake and also 

 from St Huberts, the galls being numerous in both places. This 

 latter is another new record for the State.
