C. confluens Harris. Oak or May Apple. 



Length nearly 6 mm. ; head and thorax black and roughened 

 with numerous little pits and short hairs, body posteriorly smooth 

 and of a shining pitch color; legs dull brownish red; anterior 

 wings with brown spot near the middle of the outer edge. 



The galls of this species are said to be the largest of the so- 

 called oak apples. They grow on the leaves of the red oak, are 

 round and smooth, and measure from 37 to 50 mm. in diameter. 

 At first the gall is green and somewhat pulpy, but when mature 

 it consists of a thin brittle shell of a dirty drab color which 

 encloses a quantity of brown spongy material in the centre of 

 which is a single cell about the size of a pea, which cell is the 

 final home of the larva and chrysalis. The adults emerge prob- 

 ably as a rule in the spring, but they have been noticed to come 

 out in the fall.
