suspect that when sufficient Oregon material is available 

 we shall find that rhypodella is merely one of the nu- 

 merous color forms of ovalis. 



Type locality: "Oregon" (type lost?). 



Food plant: Unknown. 



73. Phobus, new genus 



Type of genus: Dioryctria brucei Hulst. 



Characters of Telethusia except: Eighth abdominal 

 segment of male with a pair of ventrolateral hair tufts. 

 Penis of male genitalia armed with a single cornutus; 

 usually also a cluster of very fine, minute, slender spines 

 at apex of aedeagus (but not on membranous penis). 

 TranstUla represented at least by its lateral elements, 

 sometimes the median area is recognizable but is very 

 weakly sclerotized and the completed band not a con- 

 stant character. Female genitalia with ovipositor nor- 

 mal (not strongly sclerotized) ; apophyses of ovipositor 

 and eighth-segment collar slender; bursa copula trix 

 simple (smooth); membrane between collar and ovi- 

 positor smooth. 



The foregoing differences seem to justify separation 

 from Telethusia, with which the genus is very closely 

 related.

 Nephopteryx lallatalis brucei (Hulst) McDunnough, Check list, 



No. 6160, 1939. 



Forewing whitish more or less dusted and shaded with 

 blackish or fuscous scales, making the general color 

 cream white (with some pale brownish shading on paler, 

 weakly marked examples) to ashy gray with a faint 

 bluish gray tint (on well-marked specimens) ; the trans- 

 verse lines irregular and more or less interrupted and 

 not strongly contrasted; antemedial line oblique, ser- 

 rate, interrupted at lower fold by a pale olivaceous- 

 ocherous shade which extends rather broadly the length 

 of the fold and also cuts the subterminal line; a similar 

 but somewhat weaker shade fills the cell; outer margin 

 of antemedial line consisting of a thin blackish line 

 curving outwardly from costa to top of cell, a small 

 blackish dot or dash on lower vein of cell and a similar 

 blackish marking on vein lb; subterminal line markedly 

 serrate, deeply indented (almost to cell) below costa, on 

 weU-marked (darker) specimens bordered inwardly by a 

 black line from costa at least to cell, this line frequently 

 continued along top of cell to the black outer marking 

 of antemedial line, forming a continuous, long, narrow 

 hook along the median and postmedian subcostal area; 

 below the lower fold the blackish outer border of the 

 subterminal line is also continued back, as a black line 

 under vein lb to and fusing with a narrow blackish line 

 on the outer edge of the antemedial line forming a nar- 

 row, oval marking on lower margin between the trans- 



verse lines; on dark examples a more or less conspicuous, 

 blackish, quadrate patch inwardly bordering the ante- 

 medial line at inner margin; on pale specimens this 

 patch pale brown, more or less obscured; discal dots 

 obscured, rarely distinguishable; a row of small narrow 

 black or brownish dots along termen. Hind wings 

 subpellucid with a faint ocherous tint; the veins not 

 appreciably darkened; a faint narrow dark shade along 

 termen. Alar expanse, 26-29 mm. 



Male genitalia with cornutus small, slender. Female 

 genitalia with bursa very short, not much longer than 

 ductus bursae. 



Type locality: Colorado (type in AMNH, ex Rut- 

 gers). 



Food plant: Unknown. 



Distribution: Colorado; Utah, Eureka (June, July), 

 Stockton (June, July, Sept.) ; Nevada, Ormsby, and one 

 female with only the state locality (a pseudotype of 

 lallatalis Hulst); California, San Luis Obispo; Washing- 

 ton, Pulbnan (July). 



All specimens of this species in the National Collec- 

 tion had been identified as lallatalis Hulst on Dyar's 

 misidentification of the latter species. As a result 

 Dyar referred hrucei as a synonym of lallatalis. Hulst, 

 however, was primarily to blame for the confusion; for 

 he had identified and sent out as "types" of lallatalis 

 specimens of both brucei and Interjectio denticulella. 

 The true brucei resembles superficially both lallatalis 

 and denticulella in some of its more strildng details of 

 maculation, but is easily distinguished from both by 

 its male and female genitalia. 



281. Phobus funerellus (Dyar), new combination 



Salebria funerella Dyar, Ins. Insc. Menstr., vol. 13, p. 12, 1925. — 

 McDunnough, Check list, No. 6193, 1939. 



Forewing blackish to dark brownish gray more or less 

 dusted with white on basal, median, and terminal areas ; 

 the white dusting very faint and scattered on the type 

 series from Southern California, which have a uniform 

 blackish gray ground color, much stronger on specimens 

 from Washington, British Columbia, and New Mexico ; 

 transverse lines and thin blackish borders complete (not 

 interrupted as in brucei), sinuate; the antemedial line 

 oblique, sharply serrate, narrow, whitish gray, bordered 

 outwardly by a narrow black line and inwardly by a 

 broad, unbroken blackish or (on paler examples) dark 

 gray-brown band, this band distinguishable and con- 

 trasted even on the darkest, most suffused examples; 

 subterminal line seri'ate but not deeply indented below 

 costa, bordered inwardly by a narrow, continuous black 

 line, the latter not continued inwardly below costa or 

 on vein lb as it is on brucei; subterminal line bordered 

 outwardly by a rather broad dark band; discal dots 

 usually distinct, black, more or less confluent; a row of 

 blackish dots along termen. Hind wing brown; the 

 veins darkened and a narrow blackish line along termen. 

 Alar expanse, 24.5-30 mm. 



Genitalia similar to those of brucei. 



Type locality: Southern California (type in USNM). 



Food plant: Unknown.
