46 THE BIOLOGICAL REVIEW. 



color ; the wings, with abundant dark pile ; the venation is 

 typical of diplosis. The first longitudinal vein, slightly separated 

 from the costa, coalesces with it about its middle ; the second, 

 curving gently backwards, reaches the tip of the wing, where it 

 joins the stout costa, which there becomes abruptly attenuated ; 

 the third forks about the middle, one branch bending abruptly 

 to the outer margin, the other extending upwards and outwards, 

 touching the margin where it bends slightly inwards. There is 

 a rudimentary vein, springing from the base of the second longi- 

 tudinal vein and running some distance upwards, about midway 

 between it and the third. I have found no trace of a cross vein 

 between the first and second longitudinal veins. The antennae 

 of the tf is 26-jointed, that of the 9 , 14-jointed ; numerous 

 specimens. 



Torymus longior has the front of the head bright brassy, with 

 purple reflections, with five longitudinal lines of short, stubby, 

 pale spines ; eyes, pale brown ; scape of antennas, pale ; occiput, 

 bright brassy green ; thorax, dull brownish green, with brassy 

 reflections ; dorsum of prothorax, bright brassy green ; 

 abdomen, dark purplish blue, with bright brassy reflections ; 

 ovapositor, more than twice as long as body and head ; middle 

 and hind femorae, very bright steel blue, much brighter than the 

 abdomen ; all the tibia?, pale coppery brown ; tarsi, pale ; claws 

 dark ; numerous specimens. 



Torymus helianthi has the head of uniform bright, metallic 

 green ; eyes, pale brown ; scape of antennas, pale ; thorax and 

 abdomen, bright metallic green, abdomen with steel blue reflec- 

 tions ; ovapositor, about as long as abdomen ; legs, pale straw 

 color ; hind tibiae, pale brown ; tarsi, pale, tipped with brown ; 

 numerous specimens. 



On June 23, 1893, these galls were nearly full grown, of a 

 greenish color, similar to the stem of the plant, and of an 

 herbaceous texture. On July 27 they were mature, rigid and 

 hard, and of a greenish purple color. This is the most common 

 of the three helianthus galls found near Toronto.
