REVIEW OF MOTH GENUS HAIMBACHIA — CAPPS 639 



Frons weakly conical. Head, thorax, and palpi white, with a pale 

 ochreous tinge; the palpi with intermixtui'e of fuscous distally. Abdo- 

 men whitish buff with basal segments ochreous dorsally. Forewing: 

 Upper surface ground color white, with a pale ochreous or buff tinge, 

 irrorated with brownish fuscous, the irroration rather intense. 

 Medial line buff, definition weak; origin from slightly before middle of 

 costa, oblique outward to vein 7, loop enclosing the cell broad and 

 extending well beyond end of cell, angled inward and outward between 

 cell and vein 2, thence slightly sinuate and oblique inward, terminating 

 at or slightly before middle of inner margin of the wing. Postmedial 

 oblique bar buff, subparallel to and extending to inner margin of 

 subterminal band. Subterminal band with origin from costa about 

 one-fifth length of wing before apex, slightly oblique from costa to vein 

 6, remainder broadly curved and subparallel to termen; central area 

 white, inner and outer margins brownish, with little or no indentation 

 at vein 2. Terminal line discontinuous, fuscous patches small. 

 Fringe metallic. Facies brownish. Hindwing: Upper surface ochre- 

 ous white, with an indistinct double subterminal line, buff, extending 

 from costa to vein 2; terminal line single, buff. Fringe gray, tipped 

 with buff. 



Male genitalia (figs. 2-2b) : Symmetrical. Dorsal basal lobe of 

 harpe with costa broadly rounded, hook from the lobe slender, 

 slightly curved, undulate, not enlarged distally. Vinculum elongate, 

 ventral margin deeply incur vate. Aedeagus with numerous spinules; 

 somewhat bifid distally, the two straplike sclerotizations subequal. 



Female genitalia (fig. 25) : The tonguelike projection bifurcate, 

 angulation of median area of the bifurcation obtuse or nearly so. 

 Ventral margin of ostium rounded, convex. Ductus bursae sclerotized 

 from ostium to origin of ductus seminalis, constricted near middle. 

 Signa two small, round, slightly convex and scobinate, weakly 

 sclerotized areas. 



Type: Male, in U.S. National Museum, USNM 25550. 



Type locality: Cayuga, Guatemala. 



Food plant: Unknown. 



Remarks: Only two species with a conical frons, dumptalis and 

 maroniella, have brownish facies. See remarks under the latter for 

 distinguishing characters of habitus. The male genitalia of dumptalis 

 resemble those of placidella and quiriguella, but in both j^lo^cidella and 

 quiriguella the costa of the basal dorsal lobe is triangularly produced; 

 in dumptalis, it is broadly rounded, with no conspicuous production. 

 The female genitalia of dumptalis are somewhat similar to those of 

 placidella and squamidella, but the ductus bursae of dumptalis is 

 distinctly constricted about midway between the ostium and origin
