AMERICAN MOTHS OF THE SUBFAMILY PHYCITINAE 



191 



Forewing ocherous gray; antemedial line broad, 

 slightly oblique, orange, preceded by a blackish line 

 which extends from middle of cell to inner margin; 

 discal dots at end of cell, blackish, the lower one always 

 distinct; subterminal line very faint, whitish, indis- 

 tinctly shaded inwardly by dark scaling, indented at 

 vein 6 and lower fold; terminal dots faint. Hind wing 

 translucent, whitish with a pale smoky tint. Alar 

 expanse, 13-22 mm. 



Male genitalia with apical hooked process of gnathos 

 but slightly curved; aedeagus with a row of 4 or 5 very 

 small spines near apex. Female genitalia as given for 

 the genus. 



Type locality: Ai-izona (type in Paris Mas.). 



Food plant: Unknown. 



Distribution: United States: Arizona, Baboqui- 

 vari Mts. (Apr. to Dec), Greaterville, Palmerlee (Apr.), 

 Santa Rita Mts. (May, June, July), Wilgus Mts.; 

 New Mexico, Albuquerque (July), Las Vegas; Texas, 

 Alice (June), Blanco County (Jiily, Oct.), Brownsville, 

 Burnet County, Kerrville (Apr., July), Shovel Moun- 

 tain. Mf;xico: Sonora. 



Superficially aureofasciella is easily confused with 

 Eumysia pallidipennella, especially the female. Their 

 genitalia, however, readily separate the two species. 



382. Alacroirbinia placidella (Zeller) 



Myelois placidella Zeller, Isis von Oken, p. 874, 1848. 

 Dolichorrinia placidella (Zeller) Ragonot, Monograph, pt. 2, 

 p. 190, 1901. 



This species is represented only by the female type in 

 Berlin. According to Ragonot the specimen is in poor 

 condition. I have seen nothing from tropical America 

 that matches Zeller's description or Ragonot's figure 

 (Monograph, pi. 31, fig. 20). Very likely the species 

 does not belong in Macrorrhinia, but without evidence 

 to the contrary must be left where Ragonot placed it. 



Type locality: Alegrete, Brazil (type in Mus. Univ. 

 Berlin). 



Food plant: Unknown. 



95. Genus Ocala Hulst 



Ocala Hulst, Canadian Ent., vol. 24, p. 61, 1892. (Type of 

 genus: Ocala dryadella Hulst.) 



Characters of Macrorrhinia except: Labial palpus of 

 male grooved to hold maxillary palpus; maxillary pal- 

 pus of male in the form of an aigrette. There is no 

 structural difference between the two genera in the 

 tufting of the male abdomen. Hulst made no dissec- 

 tions and consequently failed to see the eversible tufts 

 in Macrorrhinia. 



The palpal differences may be of no more than specific 

 significance here as they are, for example, in Dioryctria ; 

 but imtil more material is available, other possible 

 species discovered, and something known about their 

 life histories it seems ad visible to keep the generic 

 names separate.

Forewing pale fuscous gray; antemedial white line 

 obscure, indicated chiefly by a narrow outer bordering 

 of blackish scales, angled slightly at middle and slanting, 

 bordered inwardly on lower half by a pale orange spot 

 behind which, on iimcr margin, is a rather conspicuous 

 blackish dot; discal spots at end of cell distinct, black- 

 ish; subterminal line faint, with a blackish inner border, 

 inwardly angled at vein 6 and (slightly) at lower fold ; a 

 row of blackish dots along termen. Hind wings trans- 

 lucent, pale smoky white, with some dark streaking on 

 the veins, especially on the females. Alar expanse, 

 14-17 mm. 



Male genitaha with outer margin of cucuUus straight; 

 aedeagus smooth. Female genitalia with ductus bursae 

 sclerotized for a short distance from genital opening and 

 swollen for more than a third of its length from junction 

 with bursa copidatrix. 



Type localities: Charlotte Harbor, Fla. {dryadella, 

 in AMNH, ex Rutgers); Fort Myere {'platanella, in

Food plant: Unknown. 



Distribution: Florida, Charlotte Harbor, Ever- 

 glade (Apr.), Fort Myers (Apr.), Marco (Apr.).

Maricopa Hulst, Phycitidae of N. Amer., p. 205, 1890. (Type of 

 genus: Ciris laiivilclla Ragonot.) 



Tongue well developed. Antenna cihate in male 

 (cilia over twice the width of the shaft); simple in 

 female. Labial palpus porrect (downcurved), long 

 (projecting about 3 times the length of the head beyond 

 it). Maxillary palpus minute, filiform. Forewing 

 smooth; 11 veins; vein 2 from before outer angle of 

 cell; 3 from the angle; 4 and 5 stalked; 6 from below 

 upper angle of cell, straight; 10 from cell, closely ap- 

 proximate at base or connate with the stem of 8-9 ; male 

 without costal fold. Hind wing with vein 2 from very 

 close to outer angle of cell; 3 and 5 stalked; 7 and 8 

 approximate or weakly anastomosed just beyond cell; 

 cell slightly less than one-half the length of the wing. 

 Eighth abdominal segment of male mth a short pair of 

 ventrolateral hair tufts. 



Male genitalia with apical process of gnathos a rather 

 short, stout hook. Harpe with broadened cucullus, its 

 outer margin rounded; a transverse sclerotized ridge 

 extending from base of costa to lower angle of cucuUus. 

 Anellus an elongate, curved plate with lateral lobes. 

 Aedeagus short, slender; penis without armature. 

 Vinculum short, terminal margin rather broadly 

 rounded.
