REVIEW OF MOTH GENUS HAIMBACHIA — CAPPS 635 



both the inner and outer margins of the subterminal band with fuscous 

 predominating from vein 6 to inner margin of the wing; indentation of 

 the margins of subterminal band at vein 2, weak, broadly concave or 

 but slightly angulate. Postmedial oblique bar parallel to anterior 

 part of subterminal band, short, stout, not extending beyond stem 

 of veins 7 and 8. Fringe nonmetallic. Female paler and definition 

 of markings weaker than in the male. 



Male genitalia (figs. 9-9b) : Asymmetrical. Hook from dorsal basal 

 lobe of left harpe, stout, curved, sharply pointed; that of right harpe, 

 straight or nearly so and strongly dilated basally. Aedeagus not 

 conspicuously expanded distaUy; distal half armed with numerous, 

 fine spinules. 



Female genitalia (fig. 27) : The tonguelike projection strongly 

 bifurcate, median area of the bifurcation deeply and acutely angulate. 

 Ventral margin of ostium evenly curved, slightly convex, but no 

 median production present. Two subequal signa, each a short, sharp 

 spine from a srnall circular base. 



Type: Male, in U.S. National Museum, USNM 25553. 



Type locality: Venadio, Sinaloa, Mexico. 



Food plant: Unknown. 



Distribution: Known only from the type locality. 



Remarks: Dyar and Heinrich (1927) erred in concluding that 

 prestonella represented the male of quiriguella Schaus, and their 

 synonymizing it under that species is incorrect. The series of gloriella 

 Schaus, with the same type locality as prestonella, which they studied 

 was a mixture. They did not dissect the type of gloriella, and un- 

 fortunately the specimen they selected and figured under their number 

 71 as gloriella is not that species but is the female of prestonella. The 

 specimen has a conical frons, and the fringe of the forewing is non- 

 metallic; gloriella has a rounded frons, and the fringe of the forewing 

 is metallic. 



Haimbachia arizonensis, new species 



Figures 12, 17 



Alar expanse: Male and female 16 mm. 



Frons conical. Fringe of forewing nonmetallic. Color and macu- 

 lation similar to prestonella but definition of the markings usually 

 weaker and reliably distinguishable from prestonella only by the 

 genitalia. 



Male genitalia (figs. 12-12b) : Asymmetrical. Resembling those of 

 both squamulella and prestonella, but more like the latter. In ari- 

 zonensis, the vinculum is broader and the distal hooks of the harpes 

 and the aedeagus are more slender than in prestonella.
