126 MAINE AGRICULTURAL EXPERIMENT STATION. 



Starting near the base of the manubrium and running 

 obliquely up the side of the body and ending in the dorsal view 

 is a stripe of oblong whitish spots. The white spot next to the 

 dorsal end placed inward out of line. Fig. 3, a. 



We have tried to show the arrangement of these markings in 

 Figs. 3 and 4. 



Description of Figures: — Fig. 1, drawn by Mr. J. H. Emerton 

 from live specimens, shows well the form of the body -and the 

 obscure transverse bands. The drawing was made from live 

 specimens. Fig. 2, drawn by Mr. Emerton, shows a ventral 

 view of the same. Fig. 3, drawn by the writer, shows in detail 

 the white markings as seen in alcoholic specimens, examined 

 by high powers. No attempt is made to show more than the 

 location of the markings. Fig. 4, is a side view showing loca- 

 tion of the spots. Fig. 5, shows structure of the foot. 



Remedies: — We do not agree with Fitch that the work of the 

 Smynthurids is entirely secondary, at least this species is capable 

 of sucking the juices in someway without the aid of other insects. 

 The above species was very abundant on cucumbers in my gar- 

 den this season but we did not notice the Flea Beetle. Some 

 times there Would be more than a dozen on a single leaf. In a 

 few days the leaves turned whitish and on examination the epi- 

 dermis was found full of little pits. Rarely, if ever, was there a 

 hole through the leaf. They attack the new, young plants, eat- 

 ing the seed leaves (cotyledons). The application-of dirt, ashes, 

 sulphur or pyrethrum while the dew is on will act as deterrents 

 until the plants are larger when they appear to do but little 

 damage. We searched for specimens June 25th, and found 

 them very- scarce.
