venient shelter in the tuft of grass, they availed themselves of it. Dr. 

 Harris has recommended old cloth to be used for this purpose ; and it is 

 evident that if these facts be taken advantage of when the infected apples 

 begin to drop prematurely, the summer and autumn broods may be materi- 

 ally diminished. It is of most importance to attend to the latter brood, 

 which furnishes the individuals that live through the winter, and thus pre- 

 serve the species for another year. 



3. Aphis (Pemphigus) Stamineus. This name is proposed for a large 

 species of aphis which forms follicles on the leaves of the silver-leaved 

 maple, (acer eriocarpum.) The specimens were sent to us by our ex- pres- 

 ident, Caleb Cope, Esq. This curious aphis appears to be a new species. 

 Dr. Fitch, in the descriptions of the New York State Cabinet, mentions the 

 European aphis aceris as occurring in New York, and may have this woolly 

 species in view. But the description of the foreign one does not mention 

 the remarkable filaments which approximate the insect to certain tropical 

 forms. Both sexes are covered with white down, and have a bunch of white 

 filaments posteriorly, some of which are three-fourths of an inch long, a 

 character in which this species surpasses the Eriosoma of the apple tree. 

 Male — black, feet long, slender, and rufous ; tarsi bi-articulate; wings slightly 

 deflexed, translucent, pale ferruginous at the base ; submarginal nervure 

 conspicuous, black, and ending in a long stigma ; disc with four simple 

 nervures ; posterior wings with three nervures ; mesonotum polished, with a 

 deep Y-shaped impression ; abdomen without tubes ; promuscis obsolete ; 

 antennae 6 — articulate, the first two short, the 3d long, and the 4th, 5th, 6th 

 gradually lengthening ; length of the body li lines, or to the end of the 

 wings 2^. Female and pupa — apterous, dark reddish brown, feet paler ; 

 promuscis twice as long as the head, thickened near tlie apex; length li 

 lines. 



PITTSBURGH HORTICULTURAL. 



The Board of Managers of the Pittsburgh Horticultural Society met in 

 their rooms, in Burke's Buildings, yesterday morning, H. Woods in tlie 

 chair, and H. L. Ringwalt acting as secretary. 



The committee appointed to examine the various varieties of our straw- 

 berries reported as follows : — 



Your committee, having examined the several kinds of strawberries grown 

 in the vicinity of Pittsburgh, and having been aided by the experience of 

 the growers themselves, as well as a close examination of the plants on the 

 ground, liave prepared the following report, to wit : — 



From the great productiveness, largeness and uniformity of size of the 

 Buist's Prize Strawberry, we consider it the best and most profitable for 

 market gardeners, and would class it first on our list. 



The Victoria, which is now called the British Queen, is an earlier ripen- 

 ing fruit than the above. A few of the first pickings, having a coxcomb 

 shape, are very large. Add to this its exquisite flavor, which makes up for 

 the shortness of the crop, and it is entitled to be second best on our list. 



We class Hovey's Seedling No. 3 on our lisL It is a very fine fruit,
