work. It is Galeruca semipnllata Clark. The eggs are pale, cylindrical 

 in shape and are placed in lit tie patches on the underside of the leaves. 

 The larvfe when first hatched are pale and cylindrical and cluster close 

 together when feeding, covering themselves with fine particles of dust 

 from the leaves. They become full grown in 14 days and then descend 

 to the surface of the ground to transform to pupse under leaves and 

 rubbish. 



A GRAPE VINE PEST. 



A. cosmopolitan leaf-beetle known as Adoxus vitis has recently been 

 found by Mr. J. R. Dobbins to be doing considerable damage to a vine- 

 yard near Healdsburg, California. The insect was determined by Mr. 

 L. E. Ricksecker, and we have also received specimens. This insect cus- 

 tomarily feeds upon the vine as its name indicates, but this is the first 

 case that has come to our notice of its attracting particular attention. 



TIN CANS vs. CRICKETS. 



In Florida, where crickets often seriously damage choice plants just 

 set out, the plan has been adopted of cutting off the top and bottom of 

 3 pound fruit cans and placing the resulting cylinder over the very 

 small rose bushes, cuttings and other small choice plants liable to attack. 



NOTES ON FRUIT-TREE INSECTS. 



Sannina exitiosa. — So far as known to me, the larva of this species 

 has not before been recorded as attacking the cherry. From the trunk 

 of a cherry tree growing in the yard of Mr. T. W. Nolte, at Mount Ver- 

 non, Indiaua, I took four chrysalids, the adults emerging from these Au- 

 gust 10 to 15. These chrysalids were found August 7, and besides 

 cherry there were both peach and plum trees growing in the same yard. 



Oberea bimaculata. — Beetles belonging to this species were sent to me 

 by Mr. E. S. Hallett, of New Providence, Indiana, with the statement 

 that they had been given him by a fruit grower, who complained that 

 they were girdling the twigs of his peach and cherry trees. The depre 

 dations were committed early in June, and do not appear to have been 

 very serious. 



Scolytus rugulosus. — Although this insect has probably been a resi- 

 dent of the State for several years, it was not until the present season 

 brought to my notice. On June 13 the beetles were observed burrow- 

 ing into the trunks and bases of the larger limbs of peach trees, in the 

 garden of Mr. T. W. Nolte, at Mount Vernon, Indiana, and apparently 

 working serious injury. There were five rows of these trees, and the 

 first tree in the second, third, and fourth rows, had, one after another, 

 dropped their foliage and died. The first tree of the first row, stand- 

 ing in a fence corner, had remained uninjured, although the first 

 of the second row had been the first to sustain attack and die. The
