original description, but are merely aborted and hidden under the 

 tegmina; the male forceps are well described by Scudder. Variation 

 is found from this sturdy, more sharply bowed type of male forceps 

 to one in which the curvature is much as in D. lincare, these specimens 

 being mainly distinguishable by the aborted and concealed wings and 

 longer pygidial spine. A number of males from Nebraska and Georgia 

 are of this more delicate type, while the single male from Burton, 

 Georgia, shows a decided general increase in size and an accompany- 

 ing attenuation. In coloration no distinct features e.xist to separate 

 the present species from D. lincare.
