contains one dipterous larva ; (c) gall on leaves, chiefly on 

 the under surface, sessile, but with only a small point of at- 

 tachment to the leaf, hence readily rubbed off, shape of an 

 apple, or slightly irregular and flattened, hard, not yielding 

 to pressure between the fingers, light green, smooth or 

 with small scattered knobs, central cavity small, walls of ir- 

 regular thickness, usually containing several cells, in each of 

 which is one larva ; size of a small pea ; (d) on leaves, 

 chiefly on the upper surface ; sessile round or slightly 

 flattened, yielding to pressure of fingers ; dark green or 

 reddish, usually smooth, sometimes with scattered knobs, 

 central cavity large, walls of uniform thickness, slight; one 

 larva in each. I am not sure as to whether (c) and (d) 

 are distinct or merely modifications of the same gall. The 

 larvae in both seem to be hymenopterous. 



Pimpinella saxifraga L. — Gall formed of a seed much inflated, 

 usually both seeds of the pair become galls, sometimes only 

 one of them. They are very readily noticeable in the 

 umbels ; are green, rounded, smooth, and about j^-inch in- 

 diameter, walls thin, central cavity large j each contains 

 one deep orange dipterous larva.

 there were perhaps more persons who "went in" for every 

 group, and consequently some of the Floras of the period 

 treated of all orders of plants from Phatierogamia down to the
