REVIEW OF MOTH GENUS HAIMBACHIA — CAPPS 645 



Distribution: Connecticut, New Jersey, Pennsylvania, and Ten- 

 nessee. 



Remarks: The ochreous facies, broader, diffuse definition of the 

 medial line and margins of the subterminal band, with termination of 

 the former anterior to middle of the inner margin of the wing, dis- 

 tinguish placidella from other species of the genus. The male genitalia 

 of placidella are somewhat similar to those of dumptalis and quiriguella, 

 but in dumptalis, costa of the dorsal basal lobe of the harpe is broadly 

 rounded, curvature of the distal hook undulate and the aedeagus 

 without a conspicuous toothlike projection; in quiriguella, the tri- 

 angular costal production of the dorsal basal lobe is narrower than in 

 placidella, the hook knoblike distally and the aedeagus serrate distally. 

 The female genitalia of placidella resemble those of dumptalis, but in 

 placidella there is no distinct constriction of the ductus bursae between 

 ostium and origin of the ductus seminalis; the rugosity of the ductus 

 bursae is more extensive and the angulation of the median area of the 

 bifurcation of the tonguelike projection is more acute and deeper than 

 in dumptalis. 



Haimbachia. cochisensis, new species 



Figure 19 



Alar expanse: Female 20 mm. 



Frons round. Head, thorax, and palpi white, with some mixture 

 of pale buff. Facies whitish. Forewing: Upper surface white, 

 irrorated with ochreous brown. Medial line narrow, pale buff"; origin 

 from costa slightly before middle, oblique outward to upper angle of 

 cell, loop enclosing cell narrow and extending well beyond end of cell, 

 oblique inward from lower angle of cell to vein 2, thence zigzag to 

 inner margin of the wing, terminating before middle. Subterminal 

 band with central area white; inner and outer margins pale buff; 

 indentation of inner margin at vein 2 deep and acute; that of outer 

 margin much weaker. Terminal line discontinuous, as narrow, dark 

 fuscous patches. Fringe with metallic cilia. Hindwing: Upper 

 surface sordid white; subterminal line weakly defined, rather diffuse. 

 Fringe white, tipped with pale brown. 



Female genitalia (fig. 19): The tonguelike projection weakly bifur- 

 cate, median area of bifurcation angulate, broadly obtuse. Ventral 

 margin of ostium weakly sclerotized, with a short, stout, median 

 projection. Two signa, each a small, round, sclerotized patch with 

 a short, blunt, conical production. 



Type: Female, in U.S. National Museum, USNM 65007. 



Type locality: Douglas, Arizona. 



Food plant: Unknown.
