lateral lobes absent; aedeagus slender, its basal end 

 broadened and flattened; penis without cornutus or 

 other armature except for a few weak scobinations at 

 apex; vinculum stout, shorter than its greatest width. 



Female genitalia with bursa small, simple, membran- 

 ous; ductus bursae short with a strongly sclerotized, 

 curved, wide, centrally notched, dorsal plate behind 

 genital opening; ductus seminalis from a smalt lobe of 

 bursa near junction of bursa and ductus bursae. 



The genus falls between Sarata and Hypochalcia and 

 has several features of each of these genera but can go 

 into neither of them on the sum of its characters. It 

 appears to be a New World analogue of the Old World 

 Hypochalcia, agreeing with the latter on most genitalic 

 characters except for its short vinculum and peculiarly 

 developed aneUus. The type of Hypochalcia (ahenella 

 (Zeller), fig. 54) has an elongate vinculum. It also 

 differs from Philodema in having much longer, smoother 

 and slenderer labial palpi, rather broad, squamous 

 maxillary palpi and smoother more glossy wing vesti- 

 ture. 



Philodema differs markedly from Sarata in that there 

 is no sexual dimorphism, the males and females being 

 alike in color and markings. 



347. Philodema rhoiella (Dyar), new combination 



FiGTTBES 406, 895 



Sarata rhoiella Dyar, Journ. New York Ent. Soc, vol. 12, p. 105, 

 1903.— McDunnough, Check list, No. 6267, 1939. 



Forewing pale, sordid, brownish gray; extreme basal 

 area dark smoky gray; the transverse lines indicated 

 chiefly by their dark borders, the latter dark smoky 

 gray; the outer border of the antemedial line more or 

 less broken and diffused; subterminal line bordered 

 inwardly by an irregular (zigzag) border, somewhat ac- 

 cented on the veins, and outwardly by a more obscure 

 dark shade; discal dots distinct, separated. Hind wing 

 smoky gray; the veins slightly darkened; a narrow dark 

 shade along termen. Alar expanse, 23-33 mm. 



Genitalia as given for the genus; figured from para- 

 types from the type locality. The male holotype was 

 without an abdomen. 



Type locality: Platte Canyon, Colo, (type in 

 USNM). 



Food plant: Rhus toxicodendron. 



Distkibution: Colorado, Platte Canyon (July) ; Utah, 

 "So. Utah" (July). 



The Utah specimens (2 cf) are larger (32-33 mm.) 

 than any of the Colorado examples; but have identical 

 genitalia and wing maculation; nothing is known of the 

 life history except Dyar's statement that two specimens 

 of the type series were reared from larvae on poison-ivy. 



81. Genus Lipographis Ragonot 



lApographis Ragonot, N. Amer. Phycitidae, p. 10, 1887; Mono- 

 graph, pt. 1, p. 562, 1893. — Hulst, Phycitidae of N. Amer., 

 p. 166, 1890. (Type of genus: Pempelia fenestrella Packard.) 



Tongue well developed. Antenna weakly pubescent; 

 on male, shaft flattened, serrate, and with sinus and 



strong scale tuft at base (except in umbrella and subos- 

 seella where the shallow sinus has a weak tuft of rough- 

 ened scales). Labial palpus porrect, second segment 

 oblique, laterally flattened, broadly scaled; third seg- 

 ment deflected forward, decidedly shorter than second, 

 its proportions obscm-ed by its long scaling and the 

 extended scaling of second segment. Maxillary palpus 

 subsquamous (small but broadly scaled, vestigial in 

 umbrella). Forewing smooth; venation as ia Sarata 

 except for a somewhat shorter stalking of veins 8 and 9 

 of forewing and a longer cell ia hind wing (nearly one- 

 half the length of the wing); 4 and 5 are also shorter 

 stalked, about one-half their lengths.' Eighth abdomi- 

 nal segment of male with a pair of ventrolateral hair or 

 scale tufts (absent in subosseella) . 



Male genitalia with apical projection of gnathos a 

 short stout hook (except in subosseella). Transtilla 

 absent except in truncatella and subosseella where it is 

 represented by its short, weak, divided elements. Anel- 

 lus with short, weak, lateral lobes (except in subosseella). 

 Aedeagus broadly expanded towards apex (except in 

 truncatella); penis armed with one or more strongly 

 sclerotized, ciu-ved, spinelike cornuti (the latter always 

 decidedly less than half as long as the aedeagus) . Geni- 

 talia otherwise as in Sarata. 



Female genitalia with bursa membranous and greatly 

 reduced, if sometimes elongate (truncatella) narrow; 

 ductus bursae scobinate and partially sclerotized near 

 its junction with bursa copulatrix, greatly broadened in 

 proportion to width of bursa (except in truncatella); 

 genital opening simple, unsclerotized; ductus seminalis 

 from bursa near junction of bursa and ductus bursae. 



Lipographis agrees with Philodema and differs from 

 Sarata in that the males and females are alike in color 

 and markings. It is distinguished from both Sarata 

 and Philodema chiefly by its female genitaUa. The 

 latter resemble those of the type of the Old World 

 Divona Ragonot (ilignella (Zeller)) except that the 

 bursa of ilignella is strongly scobinate, partially sclero- 

 tized, and proportionally much larger. 



In his original description of Lipographis, Ragonot 

 designated fenestrella as type of the genus. Later 

 (Monograph, 1893) he cites humUis as its type. This 

 substituted designation is invalid, regardless of the fact 

 that humilis was an originally included species and may 

 have served as the basis for the original generic descrip- 

 tion. That humilis now proves to be a synonym of 

 fenestrella is also immaterial and irrelevant. 



One species (subosseella) originally described in lApo- 

 graphis is here provisionally retained in the genus. It 

 may eventually have to have a new generic placement 

 as its only representation (the male type) is aberrant 

 in several genitalic details. 



' The venation of fenestrella and leoninella exhibit considerable 

 individual variation; veins 4 and 5 of forewing are normally ap- 

 proximate for a short distance from cell but sometimes divergent 

 and (rarely) even shortly stalked. In one freak specimen before 

 me vein 4 is also absent from hind wing, another example which 

 advises caution against relying too much upon one structure for 

 the identification of phycitids.
