NO. 3561 LOXOSTEGE—CAPPS oi 
Remarks.—L. huachucalis resembles coloradensis much more closely 
in genitalia than in habitus. In the male genitalia of huachucalis the 
pad is narrower and more extenuate and the aedeagus is stouter, with 
distal bifid elements more strongly developed than in coloradensis. 
The female genitalia of coloradensis are distinguished from those of 
huachucalis by a difference in the midventral configuration of the 
eighth sternum, the inconspicuous reduction in width of the ductus 
bursae from midway between the ostium and the origin of the ductus 
seminalis, and the stronger spinulation adjacent to junction of the 
ductus bursae and bursa copulatrix. 
Loxostege marialis, new species 
Fiaures 47, 76, 125 
Mate (fig. 125).—Alar expanse 24 mm. Frons conical. Antenna 
weakly ciliate. Midtibia incrassate; hair-pencil distinct, white. Outer 
spur one-fourth as long as inner. Similar to hauchucalis but with 
ground color less ochreous, markings somewhat finer, wings slightly 
more hyaline. 
Genitalia (fig. 47): Harpe without digitate setae; pad moderately 
broad, spinulate; sacculus with two conspicuous subequal spines. 
Aedeagus stout, median constriction conspicuous, bifid distally, the 
dorsal element strongly sclerotized, narrow, spinulate. 
Frema.r.—Alar expanse 24-26 mm. Similar to male in color and 
maculation. Genitalia (fig. 76): ductus bursae of approximately same 
width from ostium to origin of ductus seminalis; midventral configura- 
tion of eighth sternum widest at ostium, lateral margins subparallel, 
pigmentation and granulation ending before ostium. 
Typr.—Male, U.S. National Museum, USNM 67612, genitalia slide 
HWC 7903. 
TypE-LocaLity.—Volcan Santa Maria, Guatemala. 
ParaTyYPEs.—Guatemala: type-locality, 3 o, 3 9; Duenas, 1 9; 
Calderas, 1 &. Paratypes in the U.S. National Museum, British 
Museum (Nat. Hist.), and Canadian National Collection. 
Foop pLtant.— Unknown. 
In FLIGHT.—June. 
Remarks.—The lack of an outer cluster of small spines on the 
sacculus, the broader pad, and stouter aedeagus of marialis distin- 
guishes its males from those of huachucalis. The nonpigmented, 
smooth, membranous, concave area at the base of the midventral con- 
figuration, in combination with the rather inconspicuous constriction 
of the ductus bursae midway between the ostium and the origin of 
the ductus seminalis, is diagnostic of the females of marialis. 
The paratypes from Calderas and Duenas are from the syntype 
series of Phlyctaenodes conisphora Hampson.
