production of the ventral margin of the ostium and lack of a signum 

 are characteristic of the females. 



Haimbachia indistinctalis, new species 



FiGTJBE 11 



Alar expanse: Male 18 mm. 



Frons moderately conical. Head, palpi, and thorax sordid white 

 with intermixture of smoky fuscous. Forewing: Upper surface 

 whitish, rather densely irrorated with fuscous or buff, the irroration 

 absent on veins. The two transverse markings poorly defined; medial 

 line cinnamon brown, origin from or slightly before middle of costa, 

 sharply outward to stalk of veins 8 and 9, loop enclosing the cell 

 broad and extending well beyond end of cell, from outer angle of cell 

 approximate to lower margin of the cell and inward to origin of vein 2, 

 thence oblique inward and terminating on inner margin at about one- 

 third its length from base of wing. Subterminal band with central 

 area and outer margin rather poorly defined; origin from costa about 

 three-fourths length of costa from the base; inner margin evenly curved 

 outward to vein 7, posteriorly to vein 5, obliquely inward to veins 2 

 and lb, thence obliquely inward and terminating on inner margin 

 slightly before tornus. A small blackish patch on discocellular be- 

 tween veins 4 and 5. Terminal line discontinuous, the dots fuscous. 

 Fringe nonmetallic. Hindwing : Upper surface white, with a narrow, 

 buff, terminal line. 



Male genitalia (figs. 11-llc): Symmetrical. Dorsal basal lobe of 

 harpe broad basally, narrower and rounded distally, costal margin 

 undulate; the hooklike projection short, stout, rather truncate distally. 

 Aedeagus with one or two weak, slender cornuti and numerous minute 

 spinules. 



Type: Male, in U.S. National Museum, USNM 65004. 



Type locality: Brownsville, Texas, 



Paratype: One male, Kerrville, Texas. 



Food plant: Unknown. 



Remarks : In general appearance, indistinctalis resembles pallescens 

 but differs in being duller, the forewing less acuminate, the transverse 

 lines darker, the fringe metallic and having a conspicuous discocellular 

 fuscous patch. 



The female is unknown.
