on all the veins except vein 4; along termen, between the 

 vein ends, a row of very faint blackish dots; no discal 

 marks at end of cell. Hind wing shiny white, semihya- 

 line, with a faint pale fuscous shading along costa, on 

 veins 6, 7, and 8, and at extreme apex. Alar expanse, 



34 mm. 



Genitalia with lateral margins of anellus smooth; 

 vinculum with terminal margin straight, rather broad, 

 lateral margins excavate. 



Type locality: San Diego, Calif. (July; type in 

 USNM). 



Food plant: Unknown. 



Known only from the unique male type. It is a 

 striking species and should be easily recognized from 

 the description and genitalic features.

 378, 1939. 



Palpi, face, head, thorax, and forewing dark grayish 

 fuscous. Forewing very faintly dusted with white on 

 costal half; lower half of wing faintly shaded with dull 

 luteous ocherous; antemedial and subterminal lines as 

 in leuconips, except antemedial not obUterated toward 

 costa; veins 2 to 9 very faintly outlined in black, the 

 black lining most distinct on lower vein of cell; a con- 

 spicuous black spot at end of cell; along termen, be- 

 tween the vein ends, a row of rather conspicuous black 

 dots. Hind wing shiny white, semihyaline, with a 

 fuscous shade bordering costa and a pale fuscous line 

 on termen for a short distance from apex. Alar expanse, 



35 mm. 



Male genitalia with lateral margins of anellus smooth; 

 vinculum with terminal margin straight and narrow, 

 lateral margins outwardly angled. 



Type locality: San Luis Potosi, Mexico (type in 

 USNM). 



Food plant: Unknown. 



This species is known only from the male type. It is 

 easily distinguished from the other two species in the 

 genus by the conspicuous discal spot on forewiug. 



146. Genus Salambona Heinrich 



Salamhona Heinrich, Proc. TJ. S. Nat. Mus., vol. 86, p. 379, 1939. 

 (Type of genus: Zophodia analamprella Dyar.) 



Tongue well developed. Antenna of male pubescent 

 and slightly serrate, of female simple and shortly pubes- 

 cent. Labial palpi of both sexes porrect with the third 

 segment downcurved, the third segment slightly longer 

 in the female than in the male. Maxillary palpus 

 squamous. Hind wing with veins 7 and 8 anastomosed 

 for more than one-half their lengths beyond the cell; 3 

 and 5 stalked. Eighth abdominal segment with a pair 

 of strong ventrolateral hair tufts. 



Male genitalia with apical process of gnathos bifid, 

 small; uncus constricted toward apex; harpe with apex 

 oblique; vinculum long; anellus with laase of plate nar- 



rowly sclerotized, arms long, cm-ved and twisted part 

 way around aedeagus; aedeagus long, stout. 



Female genitalia without signum or scobinations in 

 bursa; bursa small, smooth; ductus bursae long, slender, 

 smooth; ductus seminalis from near end of bursa. 



Larvae grayish green or blackish, according to Dodd; 

 not banded or conspicuously spotted; solitary feeders in 

 fruits of Platypuntia. 



Eggs laid singly. 



The genus is distinguished from other genera in the 

 cactus-feeding group by the following combination of 

 characters: Antenna of male serrate and pubescent; 

 labial palpi of both sexes porrect and downcurved; 

 maxiUary palpus squamous; harpe of genitalia with 

 apex obhque; vinculum long; eighth abdominal segment 

 of male bearing a pair of ventrolateral tufts; bursa 

 copulatrix of female small and without signum or 

 scobonations (smooth) ; ductus seminalis from near end 

 of bursa; larvae unhanded, dark, fruit feeders in 

 Platypuntias. 



Only the type species is recognized as belonging to 

 the genus. It is known only from Argentina.

 vol. 86, p. 380, 1939. — Dodd, Biological campaign against 

 prickly-pear, Brisbane, Australia, p. 40, 1940. 



Palpi, head, thorax, and forewings dark stone gray; 

 the scales under magnification dark grayish fuscous 

 tipped with dull white. Forewing with the costa 

 broadly margined (to top of cell) with white, the white 

 streak diminishing toward base of wing and terminating 

 before apex; no transverse lines, or discal or terminal 

 dots. Hind wing semihyaline with a smoky shade 

 along costa and a narrow smoke-brown line along 

 termen; the smoky shade somewhat more extended on 

 the female. Alar expanse 25-27 mm. 



Male genitaha characters as given for the genus. 

 Female genitalia with bursa very small and ductus 

 bursae long and very slender. 



Type locality: Carmen Patagones, Argentina (type 

 in USNM). 



Food plant: Opuntia (Platypuntia) sulphurea G, 

 Don and probably other species of Platypuntia. 



Distribution: Argentina: Carmen Patagones 

 (Jan.), Andalgald (Mar.), La Rioja. 



According to Dodd this insect is the chief enemy of 

 the cochineal scales in Argentina and is usually preda- 

 ceous on cochineal {Dactylopiiis spp.) but not un- 

 commonly the larvae feed in Opuntia fruit and flower 

 buds. From the genitalic and other structural charac- 

 ters of the moth I am inclined to doubt this. I think 

 analamprella will prove to be primarily a cactus feeder 

 and only secondarily predaceous on the cochineal scales 

 on the cactus. It is the other way around with LaetUia 

 coccidivora (Comstock). The latter is a true predator 

 and follows its coccid hosts no matter to what plant
