genital structures of luriei, namely the vinculum, tegumen, arm 

 of the transtilla, uncus, gnathos, anellus, and aedeagus, are essen- 

 tially the same as those of arizonellus. The genital characters of 

 luriei are consistent among my examples of this species and they are 

 distinct from those of all other acrolophids treated here. This species 

 is named in memory of Pierre C. Lurie, formerly of Urbana and 

 Chicago, 111.

Walsingham 's original description follows: 



Eulepiste maculifer — Labial palpi, cf, erect, the first joint thickly scaled be- 

 neath, the second and third joints without distinct tufts, brownish fuscous, 

 paler on the inner sides and above. 9 porrect, the first and second joints clothed 

 with a coarse projecting tuft; the third joint only exposed, slender. Antennae 

 brownish, having a spotted appearance owing to thin lines of rather darker raised 

 scales at the joints. Head brownish fuscous, tufted above the eyes. Thorax 

 and fore wings brownish fuscous, the latter mottled with dark ferruginous and 

 bearing a dingy white spot on the outer half of the fold and a more diff"used and 

 ill-defined patch of the same colour on the apical portion of the wing; there are 

 some dull whitish markings in the cilia and before the anal angle; along the costa 

 the brownish fuscous colouring is interrupted by paler and more greyish fuscous 

 before and beyond the middle. Hind wings brownish. Abdomen and hind legs 

 the same; tarsal joints spotted with fuscous; uncus slightly bent over, double, the 

 points closely approximate; lateral claspers elongate, attenuated posteriorly, 

 oblique at the ends, their upper e.\tremity rather pointed. Exp. al. cf, 20 mm; 9, 

 20-24 mm. 



Hab. Three males and two females from Arizona (Morrison). 



Walsingham's illustrations consisted of (figure Ic) the head of the cT 

 in lateral aspect and (figure Id) the head of the 9 in lateral aspect. 



Male genitalia. — Vinculum typical, as in other species. 



Tegumen with lateral arm weakly constricted near center, narrow- 

 ing strongly at point of articulation with vinculum, moderately 

 punctate and setose; dorsal area rather narrow, almost completely 

 separated along meson by deep cephalic emargination. 



Harpe simple, sublinear. Lateral aspect: costa and saccidus 

 reduced, slender, shortened, comprising approximate basal third of
