The species is easily recognized by the large, dark, 

 discal spot on the forewing, the most conspicuous mark- 

 ing on the insect.

No. 6300, 1939. 



Palpi, face, and head pale brown dusted with white, 

 the scales brown with their tips white. Thorax grayish 

 white shading to pale argillaceous. Forewing grayish 

 (ashy) white with blackish brown markings and a 

 rather broad pale argillaceous shading along the fold 

 and fainter traces of the same color between the veins 

 beyond ceU; veins, except on lower half of wing, faintly 

 lined with blackish brown; antemedial line incomplete, 

 acutely angled, in most specimens indicated only by a 

 broad blackish spot on the basal third of inner margin 

 extending from inner margin to vein lb, a rather con- 

 spicuous blackish patch on lower vein of cell just beyond 

 middle and an obscure blackish shade on basal third of 

 costa; subterminal line often obsolete, otherwise indi- 

 cated by a narrow blackish streak from costa to vein 8, 

 a more or less broken line between veins 5 and 2, and a 

 small blackish patch or spot on vein lb; rarely are the 

 transverse markings strongly indicated; a more or less 

 pronoimced blackish discal spot at lower outer angle of 

 cell and a few obscure blackish spots along termen 

 between the vein ends; cilia argillaceous with the scale 

 tips white. Hind wing semihyaline white with a 

 smoky shade toward apex, a fine dark line along termen, 

 and the veins faintly outlined by smoky scaling; cilia 

 white with a very faint ocherous basal shade. Alar 

 expanse, 21-30 mm. 



Male genitalia with vinculum appreciably longer and 

 apical process of gnathos proportionately smaller than 

 those of packardella. The type of stigmella (fig. 519) is 

 abnormal in that the apical process of gnathos is par- 

 tially fused. The normal bifid condition is shown in figures 

 520 and 521. Female genitalia with a weak, bandlike, 

 sclerotized ventral plate on inner surface of ductus 

 bursae at genital opening; bursa copulatrix smooth. 



Larva imusual for the family in that the sclerotized 

 rings about setal tubercles lib on mesothorax and III 

 of eighth abdominal segment are absent. In this 

 respect it is similar to the caterpillar of Etiella zincken- 

 ella which it otherwise resembles in superficial appear- 

 ance. 



Type localities: San Diego, Calif, {stigmella, in 



USNM); La Puerta, Calif, (maculicula, in USNM). 



Food plant: (Sedum) Hasseanthus elongatus (larvae 

 boring in the roots; probably also in the roots of other 

 succulents). 



Distribution: United States: California, San 

 Diego (Mar., May, June, July, Aug., Oct.), Loma Linda 

 (June), La Puerta (July), Laguna (May), Half Moon 

 Bay (Aug.). M:6xico: Baja Cahfornia (June). 



This is a variable species in size, markings, and struc- 

 ture. Extremes of difference in genitalia are shown in 

 the figures. Barnes and McDunnough (1916) pointed 

 out that maculicula was only a color variety of stigmella 

 and in their Check List reduced the name to subspecific 

 rank. I do not believe that it deserves even this status 

 for it represents only one of many color variants. In 

 some specimens the transverse markings on forewing 

 are nearly obsolete, in others more or less indicated but 

 incomplete, and in one specimen before me (Half Moon 

 Bay, Calif., Aug. 11, 1937, W. H. Lange No. 27) the 

 discal spot and transverse lines are conspicuous and 

 the latter complete except at the fold, the subterminal 

 line running from outer fourth of costa transversely to 

 outer third of inner margin, broken between veins 2 and 

 lb and with a sharp outward angulation near vein 5. 

 The genitalic differences shown in our figures at first 

 glance seem rather striking; but they are not consistent 

 and represent only iadividual variation. 



This species seems to be native to southern California 

 and northwestern Mexico. We have a series of reared 

 specimens from Laguna, Calif. A few larvae and pupae 

 have been intercepted at quarantine ports in California 

 from roots of succulents {"Sedum sp.") shipped from 

 Mexico and from another similar interception at San 

 Francisco a large (35 mm.) male was reared.
