AMERICAN MOTHS OF THE SUBFAMILY PHTCITtNAE 



245 



narrowly sclerotized. Female genitalia appreciably 

 smaller than those of parabates; bursa wrinkled and 

 more coarsely scobinate. 



Type locality: San Antonio, Tex. (type in USNM). 



Food plant: Unknown. 



Distribution: Texas, San Antonio (July), San 

 Benito (June, Aug., Sept.), Brownsville (June) ; Arizona, 

 Phoenix, "route between Dewey and Salome." 



A uniformly marked and colored species, known only 

 from collected specimens. 



505. Alberada holochlora (Dyar)

 86, p. 352, 1939. 



This is probably a synonym or, at most, a variety of 

 bidentella. The three females of the type series are the 

 only specimens I have seen. They are a trifle smaller 

 than typical bidentella, and there are some shght, though 

 hardly significant, differences in the female genitalia 

 (shown in figs. 1022 and 1023). However, until males 

 of holochlora are discovered and bidentella has been 

 reared, it will be wiser to keep the two as separate 

 species. 



According to Dodd the larvae are sohtary in habit 

 and dark blue and the eggs laid singly. 



Alar expanse, 18 mm. 



Type locality: Uvalde, Tex. (type in USNM). 



Food plant: Opuntia (Cylindropuntia) leptocaulis De 

 CandoUe. 



139. Genus Nanaia Heinrich 



Nanaia Heinrich, Proc. U. S. Nat. Mus., vol. 86, p. 353, 1939. 

 (Type of genus: Nanaia substitula Heinrich.) 



Tongue well developed. Antenna of male bipec- 

 tinate; of female pubescent. Labial palpus obliquely 

 porrect (second segment obliquely upturned nearly to 

 top of face and third segment bent forward or slightly 

 downcurved) ; third segment long (in the female as long 

 as second segment), pointed in the male, blunt in the 

 female. Maxillary palpus large, developed as a broad, 

 curved, somewhat flattened tuft of scales which reaches 

 well above middle of face. Hind wing with veins 7 and 

 8 anastomosing beyond cell; 3 and 5 stalked. Eighth 

 abdominal segment of male simple. 



Male genitalia with apical process of gnathos bifid, 

 the two prongs narrowly separated; harpe with the apex 

 somewhat tapering but bluntly rounded; vinculum 

 moderately long (longer than broad) ; anellus with base 

 of plate narrowly sclerotized, arms long, tapering, and 

 slightly twisted; aedeagus moderately stout, strongly 

 sclerotized throughout. 



Female genitalia without signum; ductus bursae and 

 bursa copulatrix simple except for fine scobinations in 

 ductus at genital opening; ductus bursae long; bursa 

 copulatrix small; ductus seminalis from middle of bursa. 



Larva bluish, not banded; sclerotized plates sur- 

 rounding body setae small ; 2 setae in group VII on ab- 

 dominal segments 7 and 8. 



The larvae are solitary feeders in the trunks of Cylinr- 

 dropuntia and Trichocereits. 



Egg and egg-laying habits unknown. 



This genus is close to Alberada but distinguished by 

 several characters: The forewings are distinctly nar- 

 rower, the vinculum is longer in proportion to its width, 

 the aedeagus more evenly sclerotized, the apical process 

 of gnathos more narrowly cleft, the anellus more de- 

 cidedly curved, the bursa simple, without signum or 

 scobinations, the transverse markings on forewing al- 

 most obliterated, and the maxillary palpi much larger. 

 The maxillary palpi are similar to those of Sigelgaita, 

 the moths of which resemble in general habitus those of 

 Nanaia. The two genera, however, are easily dis- 

 tinguished by their different labial palpi, porrect in 

 Nanaia, upturned in the males of Sigelgaita. 



Known only from Perti.

General color (except hind wings) ocherous fuscous 

 peppered with black and white; the t3'^pe darker than 

 most of the paratypes. Forewing with pale color con- 

 fined to costal half of wing; terminal area and the area 

 between ceU and inner margin darker, with very little 

 white dusting; in most specimens a rather pronounced, 

 broad, longitudinal, ocherous fuscous shade in the fold; 

 transverse and discal markings almost obsolete, in a few 

 specimens the antemedial Une faintly indicated and in 

 the palest of the paratypes the discal black dots dis- 

 tinguishable, also some black scaling along the veins. 

 Hind wing white (whitish ocherous on female) with a 

 smoky tint toward apex and termen; terminal margin 

 blackish fuscous; cilia smoky white with a dark sub- 

 basal line. Alar expanse, 37-40 mm. 



Female genitalia with no appreciable scobiaations or 

 granulations in bursa; ductus bui-sae minutely scobinate 

 at genital opening, otherwise smooth. 



Type locality: Cuzco. Peru (type in USNM). 



Food plant: Opuntia (Cylindropuntia) exaltata 

 Berger.

 wing with veins 7 and 8 shortly anastomosed beyond 

 cell; 3 and 5 shortly stalked. Eighth abdominal seg- 

 ment of male simple.

 fused, the prongs separated only for a short distance;
