(New synonymy.) 



In color and markings resembles Moodna ostrinella. 

 Forewing blackish fuscous; basal area more or less 

 shaded with red or reddish ocherous, especially on lower 

 half, this reddish shade sometimes extending outward 

 for a short distance along lower fold, reappearing in 

 tornal area; antemedial line distinct, rather wide, nearly 

 straight, and in many specimens apparently vertical but 

 actually a trifle oblique; subterminal line obscure, paral- 

 lel to termen, slightly and irregularly denticulate; discal 

 dots sometimes obscured by the blackish dusting of 

 median area but usually distinct, more or less confluent 

 and set off by some surrounding pale dusting which 

 extends in well marked specimens to costa. Hind wing 

 white, smoky white or pale fuscous; veins darkly out- 

 lined, some dark shading and a narrow dark line along 

 termen. Alar expanse, 14-20 mm. 



Male genitalia with gnathos terminating in a short, 

 bluntly pointed, straight spike; elements of transtiUa 

 thin, broad, lightly sclerotized, fusing with arms of 

 gnathos and extending beyond them to subanal plate 

 (fig. 611a); harpe with a very short digitate projection 

 from basal third of costa, apex broadly rounded; vin- 

 culum long, its terminal margin sharply angled; aedea- 

 gus long and stout. Female genitalia with ductus 

 bursae sclerotized for about half its length, the sclero- 

 tized portion longitudinally wrinkled for its entire 

 length; signum a longitudinal series of fotu- or five small 

 discs. 



Type localities: Blanco County, Tex. (nigrella, in 

 USNM) ; Tempe, Ariz, (arizonella, in USNM). 



Food plant: Unknown. 



Distribution: Texas, Blanco County (Aug.) , Browns- 

 viUe (Mar.), San Benito (Mar., June, July, Sept.); 

 Arizona, Catalina Springs (May), Mohave County 

 (Sept.), Redington, Tempe (Aug., Sept.), Yuma (June); 

 Cali-fomia, Death Valley (Apr.), La Puerta Valley 

 (July), Palm Springs (Mar.). 



Like Moodna ostrinella a variable species in color. 

 The name arizonella refers only to a color form with 

 pale reddish ocherous shading on the basal area of fore- 

 wing. Its genitalia (male and female) agree in every 

 detail with those of typical nigrella. The latter name 

 has been "kicked around" rather carelessly by later 

 authors since its original placement by Hulst. He 

 alone seems to have examined the venation, which would 

 allow reference to Ephestia but not to Moodna and 

 certainly not to Mescinia. 



605. Caudellia declivella (Zeller), new combination

vol. 80, p. 175, 1932. 

 Ephestia animosella Dyar, Proc. U. S. Nat. Mus., vol. 47, p. 345, 



1914. 



Forewing red heavily dusted with black especially in 

 the median area, the red shade more obvious in basal 

 and terminal areas and along the fold; antemedial line 

 strongly contrasted, white, narrow, straight, oblique; 

 from antemedial line to base a subcostal streak of white 

 scaling (only distinguishable in fresh specimens); sub- 

 terminal line faint and very narrow, near to and parallel 

 with termen ; discal dots obscure, some white dusting in 

 the area surrounding them. Hind wing pale trans- 

 lucent fuscous, darker on the veins and towards terminal 

 margin. Alar expanse, 10-13 mm. 



Male genitalia with transtilla complete, developed as 

 a bridge with humped central projection; apical projec- 

 tion of gnathos a very short, blunt, knoblike hook; 

 harpe simple; aedeagus rather slender. 



Female genitalia with ductus bursae sclerotized for 

 most of its length, some sclerotized ridges at the junc- 

 tion with bursa copulatrix; signa a cluster of minute, 

 blunt discs. 



Type localities: Honda, Colombia (declivella, in 

 BM); Porto Bello, Panamd (animosella, in USNM). 



Food plant: UnknowTi. Larva probably a scavenger 

 on dried vegetable matter. 



Distribution: PanamA: La Chorrera (Apr.), PoKto 

 Bello, (May), Rio Trinidad (Mar., May, June). 

 Colombia: Honda, Maraquita. 



The species is easily recognized by its male genitalia 

 which are similar to those of Manhatta biviella of 

 Europe, but unlike anything else from the Americas. 



606. Caudellia colorella (Dyar), new combination 

 Figures 614, 1101 



Ephestia colorella Dyar, Proc. U. S. Nat. Mus., vol. 47, p. 345, 

 1914. — Richards and Thomson, Trans. Ent. Soc. London, 

 vol. 80, p. 192, 1932. 



Superficially similar in every respect to declivella 

 except that reddish areas of forewing are paler, ocherous 

 red rather than dull red as in declivella. In the hind 

 wing veins 3 and 5 are sometimes very shortly stalked. 

 They are occasionally so in declivella, but in the latter 

 normally are connate (not separate as Dyar states in 

 his original description of animosella). Alar expanse, 

 11-14 mm. 



Male genitalia with transtiUa completely fused with 

 gnathos and greatly broadened posteriorly. Harpe 

 vnih short, blunt projections from costa at middle and 

 apex; uncus broadly triangulate. Female genitaha 

 with ductus bursae sclerotized for two-thirds its length 

 from genital opening, not sclerotized at junction with 

 bursa.
