Peoria johnstonif new species 



Figures 1, 78, 113, 151 



Diagnosis. — Among the three other species of Peoria with similar 

 venation, johnsioni differs from approximella and luteicostella in 

 lacking a well-developed white band anterior to the cell, and from 

 bipartitella in having the forewings a rather uniform brownish orange. 

 Either the presence of two cornuti on the vesica of the aedeagus or 

 the absence of medial or lateral processes on the gnathos will de- 

 limit males of johnstoni from the above three species. 



Description. — Frons conical, reddish brown; labial palpi with 

 basal segments white, second and third segments reddish brown 

 dorsally and on outer sides, lighter ventrally and on inner sides; 

 maxillary palpi small; antennae light brown, scape light pink an- 

 teriorly, male subserrate; occiput, patagia, and tegulae reddish 

 brown, vertex somewhat lighter. 



Forewings brownish orange; Sc, radials, cubitals, M3, and A2 

 white traced, costa traced with narrow inconspicuous white line; 

 brownish orange on lower surface. Venation as in P. bipartitella. 



Male genitalia Avith medial process of uncus bearing small ventral 

 bulge at apex. Gnathos weakly sclerotized, without apical or lateral 

 processes. Juxta U-shaped. Valvae with costa sparsely setose; sacculus 

 densely setose. Aedeagus with vesica bearing pair of ovate subserrate 

 cornuti. 



Female genitalia mth ovipositor moderately setose along caudal 

 margin. Posterior apophyses straight, base flat and shaped like 

 parallelogram with short side horizontal; anterior slightly curved, 

 tapering gradually to thickened base.
