unfolding leaf or the unopened bud, eating a circular hole into 

 the latter, the beetles evidently feeding" to a considerable extent 

 upon the more tender opening leaves, gnawing between the 

 veins, and as the foliage expands they produce a series of irregu- 

 lar, somewhat linear, skeletonized areas sometimes extending 

 through or breaking through to the under surface of the leaf. 

 In an adjacent patch there were as many as eight or ten of 

 these insects upon individual hills and, in some instances, a 

 number of buds had already been destroyed. Beetles were ob- 

 served in copulation, This insect was also reported by Mr J. S. 

 Carpenter of Marlboro as being very abundant and injurious to his 

 raspberry bushes. 



The pale yellowish brown beetles appear in early May and 

 feed upon the tender leaves and buds. In the case of bad in- 

 festations most of the tender leaves may be partly or almost 

 entirely skeletonized. The larvae feed in the fleshy head of the 

 fruit. The most satisfactory method of controlling this species is 

 early and heavy applications of arsenate of lead, preferably just 

 before the beetles appear. In the case of bad infestations it may 

 be advisable to supplement this poison application by spraying with 

 kerosene emulsion, designed to kill the beetles by contact. 



Garden flea (Smynthurus a r v a 1 i s Fitch) . An exam- 

 ination May 17, 191 1 in the raspberry patch of Mr S. R. Taber, 

 Milton, N. Y., showed that the supposed red spider was this 

 species, a comparatively innocuous form having no connection 

 with the abundance of red spider last season. These small, 

 yellowish garden fleas were rather numerous upon some hills, 

 two and three being frequently seen upon a leaf and, in some 

 instances, five or six were readily found upon one leaflet. This 

 latter, however, was exceptional. The garden fleas did not ap- 

 pear to be inflicting any material injury, possibly causing a very 

 slight rasping here and there upon the surface of the foliage. 

 There was so little damage caused by this species that remedial 

 measures were not considered necessary. 



Four-lined leaf bug (Poecilocapsus 1 i n e a t u s Fabr.) . 

 Currant shoots showing serious injury (plate 26) by this pest 

 were submitted for examination in early June by Hon. Albert 

 Yeomans, Walworth, accompanied by the statement that this 

 insect had inflicted serious damage upon an extended planting 

 of currants. This pest belongs to the family of true bugs or 

 Hemiptera, is a rather common general feeder and occasionally
