carefully all the phenomena of this freak of nature, and that they will have the apple photO' 

 graphed, with a portion of the vine, before its removal, for engraving and publication in Hor- 

 ticultural journals. — Eichmmid Whig. 



When prowing"on vines in the vicinity of hickory trees, it has ridiculously been oon- 

 sidered a hybrid fruit between these two very widely separated plants. 



The form of the gall is variable — sometimes being quite flattened or depressed, but more 

 often spherical, or ttatteeed at base and more pointed at tip. When young it is downy on 



the outside, aud succulent, with a pleasant acidu- 

 lousjflavour. When mature, it usually has eight 

 or nine longitudinal lobes, as in a musk-melon, and 

 is smoother (Fig. 38 a). A transverse section (b) 

 shows it to consist of a fleshy outside covering, like 

 the hull of a walnut, and of a much harder, 

 woody interior, with numerous longitudinal two- 

 tiered cells or cavities, the upper tier twice as long 

 and more regularly separated by harder fibre than 

 the lower. The yellow larvae are found in these cav- 

 Fig. 38 ties, and they have a brown clove-shaped breast 



bone This gall which bears so great a semblance to a fruit, doubtless carries the semblance 

 still further by falling to the ground. And, as the seed is released upon the death of the fruit 

 which surrounded it, and consigned to the bosom of the great mother earth for development, 

 so the larva) escape from the decomposing and softening gall to consign themselves likewise 

 to the same great nursery, which seems to be absolutely necessary for their well being and 

 growth, as I have ke.t the galls for over a year out of earth and away from her fecund influ- 

 ences without getting the perfect gnats. 



This gall was first described in the American Entomologist, (vol. 1, p. 106.) 



The Grape-vine Filbert-Gall, {Yitis coryloides) W. & R. 



(Order, DipUra ; Family, Cecidomyidae.) 



This gall (Fig. 39 h), as its name implies, bears some resemblance to a large bunch of 



filberts or hazel-nuts. It is found more fre- 

 quently than the other, and especially on the 

 Kiver Bank grape {Riparia), in the month 

 of July. It is an assemblage of separate 

 galls, more or less coalescent, varying in 

 number from ten to forty or more, and of 

 different shapes, being either round, irregu- 

 larly oval, fusiform or pyriform, but gener- 

 ally narrowing at the tip. When young, 

 these galls are densely pubescent or woolly 

 on the outside, but less so when mature. 

 The interior is fleshy, juicy, subacid, and a 

 tranverse section shews a single longitudinal 

 cell in each (Fig. 39 c). The gall is evi- 

 dently a deformation of a bud, ;is it springs 

 from a single point where a bud would be, 

 and often has quite a stem to it. A stunted 

 deformed leaf is also sometimes found upon 

 it, as given in the figure. 



The larva is orange-yellow, partly trans- 

 parent, partly opaque, and has the breast- 

 bone clove-shaped, as in the preceding (Fig. 

 39 a), first described in Am. Enlumologisl, 

 (I. p. 107).
