Female genitalia (fig. 17): The tonguelike projection bifurcate, 

 median area of the bifurcation broadly concave. Two signa, each a 

 small, round sclerotization bearing a short, stout, spine. 



Type: Male, in U.S. National Museum, USNM 65002. 



Type locality: Baboquivari Mountains, Pima Co., Arizona. 



Paratypes : Four males and two females, all from the type locality. 



Food plant: Unknown. 



Remarks: The female genitalia of arizonensis also resemble those 

 of sguamulella and prestonella, but the median area of the bifurcation 

 is shallow and broadly concave in arizonensis; in sguamulella and in 

 prestonella it is distinctly acutely angulate and rather deep. 



The ductus bursae is slightly damaged; a small part of it is missing 

 in the illustration.

Haimbachia quiriguella Schaus, 1922, Proc. Ent. Soc. Washiiagton, vol. 24, p. 

 137.— Dyar and Heinrich, 1927, Proc. U.S. Nat. Mus., vol. 71, pp. 34-35.— 

 Swain, 1953, FAO, Plant Prot. Bull., vol. 1, p. 89. 



Alar expanse: Male 16 mm.; female 18 mm. 



Frons conical. Fringe of forewing metallic. Resembles prestonella 

 in maculation but with iiToration brown instead of fuscous and in- 

 dentation of inner margin of the subterminal band at vein 2 deep and 

 acute. 



Male genitalia (figs. 3-3c) : Symmetrical. Costal hook of harpe 

 slender, curved, knoblike at distal end; production of costa of dorsal 

 basal lobe narrow, triangulate. Aedeagus slender, with numerous 

 small spinules and a distal serration of several small teeth. 



Female genitalia (fig. 29): The tonguelike projection bifurcate, 

 median area of bifurcation broadly angulate. Ventral margin of 

 ostium straight or nearly so. Ductus bursae much shorter than bursa 

 copulatrix; origin of ductus seminalis distinctly closer to loop of the 

 tonguelike projection than to junction of ductus bm*sae and bursa 

 copulatrix. Bursa copulatrix elongate and with two large, thornlike 

 signa. 



Type: Female, in U.S. National Museum, USNM 25552. 



Type locality: Quirigua, Guatemala. 



Food plant: Rice. 



Distribution: Guatemala, Nicaragua, and Costa Rica. 



Remarks : See comments under prestonella regarding the erroneous 

 association of that species as male of quiriguella. The specimen 

 treated here as the male of quiriguella was reared by Dr. R. B. Swain 

 from larvae feeding in rice in Nicaragua and is associated with females 

 which agree in both maculation and genitalia with the type of
