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 in a 

 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, igi8, 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 

 I 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, 19 18, 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, 19 18, 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,
