insect during the year, containing but two broods of gall-making 

 females, and that no galls are formed except by the stem- 

 mothers that hatch from the impregnated egg." 



Mr. Burrows is working on gall-producing insects, which is 

 collateral to this subject, and it is from some of his unpublished 

 manuscript that this reference is taken. Our collecting has 

 been done in the same locality. 



Subfamily SCHIZONEURIN^. 



Antenna^ short, about half the length of the body or shorter. 

 Six-jointed. When annulated, with transverse sensoria, or 

 when not annulated, with circular sensoria. Eyes in winged 

 form conspicuous, rudimentary or obsolete in some of the ap- 

 terous forms. Beak in young forms may extend to the caudal 

 end of the abdomen, moderately long in the adults and absent 

 in some of the true sexes. Thorax moderately arched. The 

 first and second discoidal of the cephalic wing usually arise 

 near each other. The third discoidal is once branched and ob- 

 solete at the base. Caudal wing may have one or two discoidals. 

 Abdomen generally has a fiocculent or pulverulent covering. 

 Honey-tubes rudimentary or absent. Style inconspicuous, 

 globular, or obsolete. The species in this subfamily may vary 

 in habit, some being subterranean, and some gall-inhabiting, 

 while others may live unprotected. 



GenuB Colopha Monell. 



Antennae six-jointed, third joint as long as the three follow- 

 ing and not extending beyond the thorax. Beak short. First 

 two discoidals of the front wing arising from nearly the same 

 point, cubital once branched. Caudal wings, with only one 

 discoidal. Honey-tubes and style wanting. 



Genus Toxoptera Koch.^^ 



Antenna? seven-jointed, on small remote frontal tubercles. 

 Beak moderately long, extending to the mesacox^e. Cephalic 

 wings, with the cubital vein but once branched. Subcosta of 

 the caudal wings with two discoidals. Legs stout and moder- 

 ately long. Honey-tubes cylindrical and moderately long.
