242 DRAGONFLIES OF NORTH AMERICA 
« 
This is a little brownish species with yellow costa and spotted abdomen. 
Face pale, vertex black except at pale tip. Occiput brown. Thorax hairy, tawny 
on front and a little paler on sides with only a suggestion of two broad brown 
stripes that widen below toward the leg bases. Legs black. Wings hyaline, costa 
and outer veins of stigma yellow. Basal brown streaks of both wings well 
developed; the broader stripe of the hind wing extending beyond the mem- 
branule. Abdomen black with sides of swollen basal segments yellow, and 
yellowish triangular spots on dorsum of segments 4-7. Apical segments and 
appendages black. 
This species which according to Muttkowski (’08) is found about 
marshy places and Kennedy (’15) in more or less open sloughs, is 
described by the latter as spending ‘‘most of their time seated on the 
tops of aquatic plants. They copulated on the wing, the male picking 
up the female as she sat on some plant. The flight was short, after 
which the male dropped the female but hovered near, while she de- 
posited by tapping the tip of her abdomen repeatedly on the surface 
of the water.”

A fine little blackish species with a very white face and twin spots of yellow 
on the seventh abdominal segment. Face pale, becoming pearly white with age, 
up to the very black streak that envelopes the frons. Occiput yellowish in middle 
with black edges and a fringe of long tawny hairs that is continued behind the 
eyes. Thorax villous with tawny hairs which hide a very obscure pattern of 
stripes; becoming wholly black with age. Carina at first pale and sides yellowish 
with diffuse blackish streaks following the 3 lateral sutures. Legs black. Wings 
hyaline with a short broad stigma and a whitish touch on the costa just beyond. 
Extreme base of both wings with 2 short blackish streaks in the subcostal and 
cubital spaces; the latter, in the hind wing, spreading rearward along the mem- 
branule. The moderately swollen basal segments of the abdomen mostly pale 
with 2 brownish streaks each side twice connected on the carinae; segments 
3-10 black with a rather conspicuous pair of yellow spots on the dorsum of 7. 
Appendages black. 
Wilson (’12) found this dragon fly “familiarly known as ‘Johnny 
White-face’.... around freshwater ponds or on side creeks; there 
were none on the river.” 
Whedon (’14) says: ‘‘they are usually very alert and agile, floating 
before the collector like a host of jet black ivory centered balls. When 
resting, the wings are thrown forward, the abdomen held high in the 
air and the head is kept turning watchfully from side to side.”’
