500 THE GOOSEBERRY MIDGE. 



three pairs of jointed legs, and behind one pair of 

 ventral, and one of pro-legs. It is of the genus 

 Geometridae, rismg upon its hind legs and throwing 

 forward those at the front, and measuring a regular

 berry. It turns red, is putrid, and, if examined, a 

 number of small, yellow maggots will be found, 

 which have been hatched from the eggs. These 

 cause the fruit to fall to the ground, when the 

 insect becomes a fly, and produces still another 

 generation the same season. The maggots of this 

 second family seek shelter in the ground during the

 the smooth varieties of the gooseberry. It some-
