above. Sides of thorax with 2 bluish stripes that become yellowish below where 
they are bordered by black, with a general background of brown; pubescence 
of thorax whitish, short in front, long below and to rearward, grading down 
the sides. Legs brown. Wings hyaline with yellow costa and brown veins and 
yellow or brown stigma. There are rather conspicuous roundish black spots upon 
and above the base of the wing roots. The swollen basal segments of the abdomen 
are tufted above with tawny hairs; apical margins of segments 2-8 are narrowly 
ringed with shining black at apex and on dorsum there are 2 pairs of yellow 
spots, the hinder pair well separated, adjacent to an apical black ring; the other 
pair subbasal, approximate, laterally tapering and confluent with obscure 
yellow, submarginal, lateral, streaks; 10 brown with conspicuous mid-dorsal 
spines. Appendages blackish.

These are huge, neotropical darners that enter only the southeastern 
U.S. The head is very wide and the abdomen is very long; likewise, the 
slender abdominal appendages, which may reach 10 or 12 mm. Veins 
M, and M,2 converge behind the stigma. The fork of the radial sector 
is very unsymmetrical and its base is under the middle of the 
stigma. The apical planate takes origin far beyond the stigma. 
These are swift-flying, powerful insects, very difficult to capture with 
a net. One of them, at least, is of economic importance as an enemy of 
the honeybee. Two species are said to occur within our limits, and a 
third lives farther southward. Ours may be distinguished as fol- 
lows:

The nymph is at once distinguished from all our other darners by 
the possession of a pair of long, sharp parallel spines besides the median 
cleft of the labium. Kennedy (’19, p. 107) has described the nymph 
of C. ingens.

This is a gigantic species with stout thorax and very long abdomen. Face 
greenish with brown-bordered yellowish labrum. Frons above with a pale brown 
T-spot and a basal half ring. Occiput yellowish. Front of thorax brown with
