margin but not shading into ferruginous ; no ferruginous 

 coloring on forewing. Abdominal tufts much stronger 

 than in lucidalis and in two distinct pairs. Alar 

 expanse, 23-28 mm. 



Male genitalia with apical process of gnathos rather 

 large; terminal margin of vinculum bluntly angulate. 

 Female genitalia with signum a thin short line of 

 minute spines; bursa copulatrix smooth except toward 

 ductus bm-sae, where it is finely scobinate; ductus 

 bursae of moderate length, swollen toward and gradually 

 expanding into bursa. 



Type localities: San Diego, Calif. (Juscomaculella, 

 in W. S. Wright Collection) ; Los Angeles, Calif, (helio- 

 pkila, m\JSNM). 



Food plant: Opuntia {Platypuntia) spp. 



Distribution: California, San Diego (May, June, 

 Aug.), Los Angeles (July), Pasadena (Aug.). 



533. Ozamia fiiscomaculella clarefacta Dyar 

 FiGUBES 67, 559, 1040 



Ozamia clarefacta, Dyar, Ins. Insc. Menstr., vol. 7, p. 55, 1919 — 

 McDunnough, Check list, No. 6292, 1939. 



Ozamia odiosella Heinrich (not Hulst), Proc. U. S. Nat. Mus., 

 vol. 86, p. 389, 1939. — Dodd, Biological campaign against 

 prickly-pear, Brisbane, Australia, pp. 39, 60, 84, 1940. 



The variety (or race) is apparently limited to south- 

 eastern Texas and eastern M(5xico. It is distinguished 

 by the presence of a greenish tint over the area bordering 

 the inner margin of forewing. According to Dodd this 

 green shade is quite distract on live or freshly killed 

 moths, but is not observable on most pinned examples. 

 There is also a slight difference in the female signum. 

 In clarefacta it consists of a narrow, minutely spiaed 

 plate. Otherwise clarefacta has nothing to distinguish 

 it from iypic&l fuscomacvlella. 



Type locality: Orizaba, Mexico (type in USNM). 



Food plants: Opuntia (Platypuntia) spp. 



Distribution: United States: Texas, Brownsville, 

 Victoria (May), Burnet County (Oct.), Uvalde (Jime, 

 July), KerrviUe (May, Jime), San Benito (Aug.). 

 MiEXico: Orizaba (Apr.), Jalapa. 



In my 1939 paper I misidentified this variety with 

 Hulst's odiosella on the basis of a female from Texas in 

 the National Collection which Hulst had labeled "Saleb- 

 ria odiosella Hulst, Type" and which both Dyar and I 

 had supposed was the true type of that species. It is 

 not the actual type, which I had previously overlooked. 

 This is in the Rutgers Collection. It is a male, super- 

 ficially similar to the spurious "type" in the National 

 Museum but structurally quite distiact ; it has 8 veins in 

 the hind wing and the maxillary palpus in the form of an 

 aigrette (as in Salebria where Hulst placed it). The 

 true odiosella is treated on page 114. 



534. Ozamia thalaseophila Dyar 

 FiGUBE 1039 



Ozamia thalassophila Dyar, Ins. Insc. Menstr., vol. 13, p. 15, 

 1925.— Heinrich, Proc. U. S. Nat. Mus., vol. 86, p. 391, 

 1939.— McDunnough, Check list, No. 6291, 1939. 



Palpi, head, thorax, and forewing dark grayish 



fuscous, lightly sprinkled with white. Forewing with 

 some white dusting on costal half and a slightly more 

 brownish shade on inner half; antemedial and sub ter- 

 minal transverse lines whitish, bordered with black or 

 blackish fuscous, the pattern as ki lucidalis and odio- 

 sella; discal spot at end of cell curved, black; between 

 this and subterminal lines one or two small, obscure, 

 blackish dots; upper and lower veins of cell faintly out- 

 lined by white scales; a row of black dots along termen 

 at or close to the vein ends ; cUia pale ocherous fuscous. 

 Hind wing white with a narrow fuscous shade along 

 termen; cUia white, with a fuscous subbasal line. Alar 

 expanse, 28 mm. 



Female genitalia with signum a small cluster of two 

 or three more or less fused and minute spines; bursa 

 copulatrix partially wrinkled (in the region of the sig- 

 num); ductus bursae of moderate length, finely sco- 

 binate toward bursa. 



Type locality: Oceanside, Calif, (type in USNM). 



Food plant: Opuntia (Cylindropuntia) sp. 



Eaiown only from the unique female type, reared 

 (Aug. 1924) from larva in a Cylindropuntia, presumably 

 feeding in the fruit.

 1913. 



Similar in color and markings to thalassophila except 

 for a faiot purplish red suffusion over the ground color 

 of forewing (especially noticeable on freshly reared 

 examples) and less white dusting on costal area of wing. 

 Alar expanse, 25-31 mm. 



Male genitaUa with apical process of gnathos rather 

 large (as in JuscomaculeUa); terminal margin of vin- 

 culum bluntly rounded. Female genitalia with signum 

 a narrow, bluntly spined plate, the signum longer than 

 any other in the genus; bursa copulatrix somewhat 

 wrinkled in the neighborhood of signum, finely scobi- 

 nate towards ductus bursae, the scobinations extending 

 for a short distance into ductus. *^ 



Type locality: Tehuacdn, Mexico (type in USNM). 



Food plant: Opuntia {Platypuntia) sp. *-^ 



Distribution: M:6xico: Caxaxa, Tehuacdn (July), 

 Zacatecas (Dec.) 



This species is very close to thalassophila but appar- 

 ently distinct. I overlooked it when treating the 

 cactus-feeding Phycititiae in 1939. Since that time a 

 series (including one male) was reared on Dec. 10, 1946, 

 by George Callaghan of the U. S. Bureau of Entomology 

 and Plant Quarantine from larvae feeding in the fruits 

 of prickly-pear at Zacatecas, Mexico.
