MITSS ( Tar son emus spp. ) 
General. F. F. Smith (September): The "broad mite, Tar son emus latus Bks. , was 
injuring dahlias in a field and Gerbera plants in a greenhouse at Media, Pa. 
Apparently the mites moved from the Gerbera to the dahlias in the early spring 
during the period that the dahlia cuttings were being made, and were later 
taken to the field. Apparently this is a new State record, An undescrlbed 
Tar son emus was associated .with £. latus on dahlias in this infestation. The 
mite was also found associated with T. pallidas Bks, on specimens of 
Delphinium belladonna sent in from ICingsford, Me. Infestations of this 
species alone, and apparently not associated with pallidus or latus , were 
found on chrysanthemum leaves at Baltimore, Md. , Alexandria, Va. , and in the 
District of Columbia; also on Delphinium belladonna in a field at Suitland, 
Md. Chrysanthemum leaves are injured on the lower surface, then become 
bronzed and brittle, much as when injured by T. pallidus . On delphinium the 
blackening 'and- dying of leaves appears very pronounced, but there is no marked 
leaf or flower-bud distortion like that caused by T. pallidus . This nite also 
apparently survived the winter and summer on delphinium. 
Washington. W. W. Baker (September): Terminal shoots of nettle (Urtica) collect- 
ed at Puyallup were found to be heavily infested with mites, which appear to 
be T. pallidus .

A COREID ( Corizus hyalinus Fab. ) 
Mississippi, C. Lyle (October 23): Specimens were received from a grower at

CHRYSANTHEMUM LEAP MINER ( l-Tapomyza chrysanthemi Kowarz) 
Mississippi. C. Lyle (October 23): Injury to chrysanthemums was reported from 
Meridian in Lauderdale County on October 14. 
MEXICAN MSAXYBUG ( Phenacoccus gossypii Towns, and Ckll. ) 
Virginia and Maryland, H. H. Richardson (September): Early in September a very 
severe infestation was found at Alexandria, Va. , on a crop of approximately 
27,000 chrysanthemums. Further investigations show that this pest is very 
generally distributed around this section as well as around Baltimore, Md. , 
being found usually on chrysanthemums.
