pinkish-red, which color extends along costa and sectors fading pos- 

 teriorly to yellow; a broad dusk}- band over crossveins, apical cells 

 fumose, 2 and 3 the least so, Underparts pale yellowish. Hypopy- 

 gium: LoAver posterior angle of ninth segment with a'*short, stout, 

 downwardly projecting, heavily pigmented tooth, upper angle squar- 

 ish (fig. 48). There is a patch of stout bristles near articulation 

 of outer clasper, and the middle of the side of this segment has 

 numerous pointed bristles; outer clasper and anal tube with the 

 usual ciliation. Outer clasper narrowed from base and spatulate 

 apicall}^ whether viewed from the side or from below; inner clasper 

 stout and hairy at base, tapering to about two-thirds of its length, 

 dilated and with a compound curve subapically, the apex sharp 

 and turned outward. Apices of both claspers heavily pigmented 

 (fig. 48). Aedeagus split from base, the parallel parts slender, 

 expanded subapically and pointed apically; the paired hooks at 

 base shown in figures are not connected to aedeagus by heavy chitin 

 but ap23ear nevertheless to be functional appendages of that organ 

 (figs. 49-59). 



Fevmle. — General color pale yellowish white, the sectors of teg- 

 men near crossveins touched with deeper yellow, the dusky band 

 over crossveins as in male. Near base of each tegmen is an elongate 

 irregular bright red spot, lying partly on clavus and partly on 

 corium but touching neither the base, costa or commissure and ex- 

 tending posteriorly to or beyond middle of tegmen. Underparts 

 pale yellowish-white, ovipositor brown, apex of sheath black. 

 Eighth sternite about evenly convex posteriorly in general outline; 

 distinctly angularly emarginate medially. 



Length, 3.5-4 mm. 



One male and several females, Urbana, 111., July 12, 1920, J. K. 

 Malloch (111. State Nat. Hist. Survey). These specimens labelled 

 " Cottonwoods;" this term does not refer to a food plant but is an 

 abbreviation for Cottonwood Grove, a locality name, which more- 

 over is the same as Augerville Grove. The specimens examined, 

 therefore, are topotypic. Mr. INIalloch informs me these specimens 

 were all collected on buckeye (^escw^w^). 



A variety without trace of the reddish spot on tegmen, but other- 

 wise typical, represented by a female with the same data as the 

 other specimens examined, may be known as var. clara, new variety.
