subsegment a smaller tubercle slightly more dorsal. Below the 
lateral line there is a tubercle on each subsegment. The submedian 
tubercles are in a nearly straight line, while in the sublateral ones, 
the larger compound one on the anterior subsegment is somewhat 
more ventral. The smaller tubercles below the lateral line are ina 
nearly straight line. Legs whitish transparent, variably spotted with 
dark brown. Prolegs whitish transparent. 
Norway maple leaf hopper (Alebra albostriella Fall.). 
A Norway maple twig was received March 27, 1918, from E. H. 
Moore, aboriculturist, department of parks, Brooklyn, showing on 
the two year old wood a badly swollen apparently cankerous condi- 
tion suggestive of fungus or bacterial infection. The surface was 
slightly ridged and with numerous small openings suggesting possible 
fungus infection and a consequent rupturing of the overlying tissues, 
though examination by State Botanist House showed no injurious 
fungus present. On cutting, numerous oval, dead areas were found 
under the unhealthy bark and an examination of last year’s wood 
disclosed under comparatively normal tissues, small oval cells about 
t mm long, some of which contained living eggs, presumably of this 
leaf hopper. It was stated that a great many trees in a large nursery 
on Long Island were affected in this manner. 
White peach scale (Aulacaspis pentagona Targ.). 
Cherry twigs rather badly infested with this insect were received 
under date of March 15, 1918, from T. F. Niles, accompanied by 
the statement that the specimens were collected at Rye and further- 
more that he had found the insect in other places. This southern 
form is rarely brought to notice in this State and an examination 
of the material disclosed nothing alive, indicating that the severe 
weather of the past winter had presumably killed a very large pro- 
portion of the insects. 
Lecanium parasites. An unusual case of parasitism was brought 
to attention through the reception from Prof. Elsworth Bethel of 
the State Museum, Colorado, of a soft scale insect, possibly 
Toumeyella pini King on Pinus edulis. The scale 
itself was almost riddled with twenty-seven small, circular exit holes 
of an unknown parasite. 
Bladder maple gall (Phyllocoptes quadripes Shim). 
Soft maple leaves showing a very general infestation by this plant 
mite were received under date of May 27, 1918, from Robert S. 
Waterman, Ogdensburg, N. Y., accompanied by the statement that 
a large maple tree some 55 or 60 feet high was infested throughout 
in this manner. ‘The galls are in an incipient stage, being marked 
on the underside of the leaf by a small, white tuft of longer hairs,
