front margin, while viciniim has a triangularly formed lamina The 
range of the species is the Transition and Upper Austral, and it prob- 
ably will be found in parts of the state by collectors.

Abd. male 21 — 24, female 22—23 ; h. w. male 24 — 25, female 23 — 24. 
Male. — Colors as nsnal, ranging from yellow to red. Face yellow 
or red, a broad olive band below the frons. Sides of thorax of younger 
specimens bright yellow. Legs entirely yellow, the claws of the feet 
blackish. Wings hyaline, nervure brownish, costa fuscous, stigma 
reddish. Abdomen yellow to red. sides marked with brown spots. 
Appendages lighter, cylindrical, with numerous inferior denticles. The 
color of the legs and the small size are distinctive. 
Female. — Similar. l\lore brown on sides of abdomen. Vulvar 
lamina entire, forming a right-angled triangle with angle directed 
outward. 
Life Zone : Transition and L^pper Austral.

Sympetrum costiferum Hagen. 
This s])ecies has as yet been found only in the Transition area. The 
imago is a triHe larger than riciinon, which it resembles, but is easily 
distinguished by the legs marked with yellow and black stripes and 
the yellow feet. The genital is distinct by having the anterior lobe 
with its apex bent inward. The female vulvar lamina is short, entire, 
somewhat rounded, the middle third emarginate. It is possible that 
this species will be found in the state. 
Sympetrum scoticum Donovan. 
The present species is more Boreal in its range. It has been taken 
in the Northern Peninsula of Michig'an and is probably to be found 
in some of our northern counties along the boundary. The points indi- 
cated in the table will suffice to distinguish it from its allies.

Hagen places 1 1 species in this genus, of which six 
inhabit North America, while the rest are found in Eu- 
rope, and in part in Northern Asia. Because of their one promi- 
nent color-feature folk-lore has given them the name of "White- 
face". Like the preceding genus they love the deep reeds of the 
marshy shores of lakes and ponds, but are rarely seen any con- 
siderable distance from the water. The generic character men- 
tioned in the table, that the upper sector of the triangle of the hind 
wing departs from the lower angle is really not quite valid as a 
distinctive feature. Specimens of both sexes taken in Wisconsin 
have come to my notice, in which the upper sector is migrated a 
trifle upward from the lower angle of the triangle. Still, the dif- 
ficulties that this inconstancy might cause are obviated in view
