1. Macrotylus 6-guttatus Prov. 
A very distinct deep black opaque species with the head polished 
and olive green or even yellowish before; the apex of the second 
antennal joint and the apical one-half of the tarsi fulvotestaceous. 
The cuneus has a large oval yellow or white spot at base and the 
apex is white. Near the end of the membrane is a large white 
marginal spot and there is a small one close to the white apical 
portion of the cuneus. I swept four examples of this interesting 
form from a low bush at Aylmer, near Ottawa, Ont., June 30, 1912. 
2. Macrotylus amenus Reut. 
This is a very small species, scarcely 24 mm. to the tip of the 
membrane. It is pale yellowish-green with the cuneus and mem- 
brane fuscous and marked exactly as in the preceding species except 
that the apical white spot is smaller. The antennz are fuscous with 
pale incisures, and the feet pale with the anterior edge of the femora 
and the tibie and tarsi fuscous or black. The type of this species 
was taken in Connecticut by Dr. W. E. Britton, Mrs. Slosson has 
taken it at Delaware Water Gap, Pa., and I took a very small 
example at Estero, Fla., in May.
