248 DRAGONFLIES OF NORTH AMERICA 
50. LeprHemis Hagen 
These are very elongate bright green clear winged dragonflies with the 
swollen base of the abdomen very much compressed, then constricted, 
then parallel and slender. The head is broad with bulging frons. The 
thorax is high and almost without color pattern. The legs are long, 
blackish and spiny. The stigma is large, surmounting little more than 
a single cell. Dr. W. T. M. Forbes reports that this big green fellow 
attacks other insects viciously, taking butterflies and other dragon- 
flies in flight almost at the mouth of the collector’s net. 
The single Neotropical species barely transgresses our southern 
border. 
The nymph is unknown.
