found on the upper side, I 

 have met with it antiposed. 

 Upon cutting into these galls 

 we shall find them to be hol- 

 low, and each to contain a 

 pale orange larva, which pro- 

 bably resembles those already 

 ^_^ mentioned in transforming un- 

 /\<^ der ground. The gall was first 

 briefly described by Baron 

 Osten Sacken (Diptera of N. 

 A., part I, p. 202). Similar 

 but distinct galls grow on the 

 leaves of Hickory and Hack- 

 berry, but are always green.

EGGS IN AND ON CANES AND TWIGS. 



Of the innumerable forms of insect-eggs which are met with on 

 plants, the few herewith described are continually sent to me from 

 correspondents who desire information as to their nature. Some of 

 them were described by me in the AmeriGan Agriculturist 

 for last August, from which I shall draw largely in describ- 

 ing them again. The first (in all probability those of the 

 Jumping Tree Cricket, Oroo/iaris saltator Uhler) are repre- 

 i sented at figure 47, and are so abundant this winter that they 

 were received from six difierent quarters just as this report 

 is going to press. 



The punctures are one-third to half an inch apart, and 

 i appear as if made by a rather large-sized pin. The illustra- 

 tion is from a piece of grape cane. On Damson twigs sent 

 by J. A. Franklin, of Bluffton, the parent insect has very 

 generally gnawed ofi" a portion of the tender bark before 

 d making a puncture — a proceeding not always followed when 

 harder wood is used. Each of these punctures leads to from 

 one to twelve slender, elongated eggs, (c), rather more than 

 the tenth of an inch long, more or less opaque and whitish, 

 I but generally of the color and transparency of amber, ex- 

 cept at the extreme head end, which lies toward the orifice, 

 and which is always opaque and very finely granulated. 

 The puncture is direct to the pith, in which the eggs are in- 

 serted lengthwise ; and the number varies, according to the 

 amount of pith in the twigs selected. About the first of May these 

 eggs hatch out into little, dingy crickets; and though I have not
