While less common than militaris, many males are available in col- 
lections (including the Peckham and Banks collections), identified 
as militaris or marginata. Chickering’s Michigan collections are 
mixed E. militaris and E. flava. Though most of Kaston’s identifica- 
tions were correct, at least some Floridian males he identified as 
E. marginata prior to his 1973 paper are E. flava. 
Male carapace with marginal band of white scales extending 
across clypeus (Fig. 13) and usually back well past the palps. Longi- 
tudinal white bands extending back from ALE usually narrower 
than in militaris. Palp femur and often patella distinctly paler than 
more distal segments. Embolus longer and thinner than in militaris, 
arising more abruptly and more directly behind the embolar base 
(Figs. 11, 12). Wrinkles on embolar base, especially the more retro- 
lateral ones, are distally curled retrolaterally (Figs. 8, 11, 12; see 
arrow in Fig. 12).

Bridgeport, Nebraska was collected by me, and the identification checked carefully.
