corded for this locality iu 1885. Several other insects in this order 

 may be noticed. Prominent among them is the Grape-vine Leaf-hop- 

 per {Erytlironeura vitis) which was very abundant iu all its stages dur- 

 ing the first part of September, 1886, on the leaves of the grape. It 

 caused considerable injury by puncturing, and thus disfiguring the 

 leaves. The perfect insects that were noticed here did not have the 

 transverse reddish bands nearly so broad as generally represented 

 iu the figures of them, but very narrow, while all the rest of the insect 

 is of a pale yellow. 



The Grain Plant-louse {Siphonophora arena') occurs some years on 

 wheat and oats, but has never doue particular damage. However, this 

 year (1889), reports from the vicinity of Constantine, and the local 

 papers, state that it has appeared in large numbers. 



The Maple Scale [Pulvinaria innumerabilis) was very abundant on the 

 maples iu 1884, being conspicuous and causing some alarm. It how- 

 ever disappeared without particular injury. 



A greenish-yellow or grayish plant bug {Ensvhistus variolarius) was 

 found in some numbers iu July, 1880, on red raspberries. Quite a 

 number of the berries were noticed on the bushes, each one having a 

 specimen of this bug upon it, which from appearances seemed to have 

 been engaged iu the nefarious practice of piercing the berry and suck- 

 ing its juices. One of these individuals was a nymph. This species 

 is very common at present, and it would not take much increase to 

 make it abundant, in which case some of our small fruits might sustain 

 a slight amount of injury, though nothing probably that would be ap- 

 preciable. 



In the Orthoptera, many species of Acrididte are common. The 

 Bed-legged Locust {Caloptenus femiir-ruhrum) was very abundant in 

 August and September, 1886, in clover-stubble, meadows and pastures, 

 and along roadsides everywhere; yet they were not particularly injuri- 

 ous. Specimens were taken in coitu from September 3 to October 12 

 on fences along the roads in the country. The first winged specimens 

 were noticed this year on August 9. The Lesser Locust {Caloptenus 

 atlanis) occurs occasionally with the preceding. This species was taken 

 in coitu from September 13 to October 13. Other species occurring with 

 these are Caloptenus bivittatus and C. differ entialis, which are usually 

 numerous. These two species were taken with G. atlanis, August 9, 

 early in the morning, on hollyhock seed-cups beginning to turn yellow, 

 which they had evidently been eating, as holes were found iu their 

 outer coverings.
