noticed, also its allied species. The substance observed upon 

 the ground beueat.li them is the remains of their excreta, dropped 

 in meal-coated globules. Their exuvia occur thickly on the 

 leaves. Injuries of aphides noticed. The best- remedy for the 

 woolly aphids may be found in crushing them as they occur 

 massed on the branches. 



The Grain Aphis in Maryland. (The Country Gentleman for 

 November 25, 1886, li, p. 893, c. 2-4 — 44 cm.) 



"Millions of parasites" reported in rye-fields in Maryland, 

 causing the young grain to appear as it sunburned, are probably 

 the grain aphis, Siphonophora avence (Fabr.). The insect was 

 very destructive in the United States in 1861, but not seriously 

 so since that time. The abundance of aphids the present year 

 and an extensive aphis flight, observed in Albany early in 

 September last, identified as this species, indicate that it 

 may occasion serious injury the coming year. Portions of its 

 life-history are not yet known. Extracts from Drs. Fitch and 

 Thomas upon it are given. Its food-plants and rapid increase 

 are referred to. The best preventive of its increase would be to 

 destroy infested crops in the autumn.

Gives the evidences of the progress in entomology during 

 the year, as shown in publications made in the several orders, 

 of which a list is given — in the rapidly increasing lists of North 

 American insects (about 25,000 species at present described) — 

 and in some of the entomological events of the year. 



A Sweet-potato Pest. (The Albany Express for December 8, 



1886.) 



Abstract of remarks made before the Albany Institute at its 

 meeting on the seventh of December, on the sweet-potato 

 weevil, Cylas formicarius (Fabr.), examples of which, in its 

 larval, pupal and perfect stages, together with an infested potato, 

 were exhibited. The insect threatens to prove in Texas a more 

 serious pest than the Colorado potato beetle.
