REVISION OF PEORIINAE AND ANERASTIESTAE 67 



designated as lectotype the specimen in the American Museum of 

 Natural History. The remaining female is deposited in the U.S. 

 National Museum, full data being given above. 



The specimens from Pecos, Tex. are atypical in that the frons beak 

 is unusually well developed and the rim is flared anteriorly so that 

 the teeth point somewhat anterolaterally. Most of the Pecos speci- 

 mens are only sparsely set with black scales on the forewings, but 

 otherwise are typical of the species.

Alamosa bipunctella Barnes and McDunnough, 1913, p. 184; 1917, p. 149. — 

 Grossbeck, 1917, p. 134. — Hampson, 1918, p. 65. — McDunnough, 1939, 

 p. 36. — Kimball, 1965, p. 251. 



Diagnosis. — This is the only member of the genus having numer- 

 ous small cornuti on the vesica of the male rather than a single one. 

 The ductus seminalis of females is thickened where it leaves the 

 ductus bursa, not slender as in other species. Otherwise, specimens 

 could be confused with small examples of calijorniella, which has 

 similar wing venation and maculation, but the two species are largely 

 or wholly allopatric. 



Description. — Frons wdth protuberance cylindrical, ventrally 

 about as long as wide, rim slanting at about 45°, teeth projecting 

 forward, central beak conical Avith irregular tip even with end of rim, 

 vesture light brown to browTi dorsally, white to light brown ventrally; 

 labial palpi usually porrect, basal segments white, second and third 

 brown dorsally and on outer sides, light brown ventrally; antennae as 

 in californiella; patagia and tegulae brown, vertex and occiput light 

 brown dorsally, occiput brown dorsolaterally, white below middle of 

 eye; legs brown on outer sides, white on inner sides. 



Forewing radius averaging about 6.9 mm; cell, discocellular, radials, 

 medials, cubitals, and anal veins each traced with a broad white band 

 sprinkled vnih. black scales; area anterior to cell varying yellow to 

 brown and sprinkled \^dth black scales; ground color yellow to yellow 

 brown; prominent black discal spot at lower outer angle of cell; brown 

 on underside; vein R4 first to branch from stalked E2+4. Hindwing 

 bordered with double brown line; fringe white; ground color light 

 broAvn, darker in apical area; Cui and M3 stalked for at least one-half 

 length, sometimes fused. 



Male genitalia mth vinculum V-shaped, pointed anteriorly. 

 Aedeagus club-shaped vesica bearing numerous small cornuti which 

 diminish in size anteriorly. 



Female genitalia with ductus bursae rather short. Ductus seminalis 

 thickened basally.
