ciliate (cilia but slightly longer than width of shaft, 

 except on male of dorsimacula where they are about 

 twice as long as width of shaft). Labial palpus of male 

 upturned, reaching vertex, slender ; third segment about 

 half as long as second, acuminate; of female obhquely 

 ascending. Maxillary palpus filiform (moderately large 

 in pagodella and grandella, minute in other species). 

 Forewing smooth; 11 veins; vein 2 from well before 

 lower outer angle of cell; 3 from the angle, much closer 

 to 4 than to 2 ; 4 and 5 approximate for a short distance 

 from cell, occasionally connate; rarely short stalked; 6 

 more or less bent towards base and more or less approxi- 

 mate to upper angle of cell; 10 normally from the cell, 

 rarely connate or shortly stalked with 8-9 ; male without 

 costal fold. Hind wing with vein 2 from well before 

 outer angle of cell; 3 from before, but near the angle; 4 

 and 5 normally shortly stalked, occasionally connate, 

 partially anastomosed or (in some large females) closely 

 approximate for a short distance from cell; 7 and 8 

 closely approximate beyond cell; cell half or (males of 

 grandella) somewhat less than half the length of wing; 

 discocellular vein curved. Eighth abdominal segment 

 of male simple or with two or three pairs of ventral hair 

 tufts. 



Male genitalia with apical process of gnathos a hook, 

 forked at apex. Uncus more or less triangulate; apex 

 rounded. TranstiUa complete, stout, arched, its cen- 

 tral area produced into two widely spaced horns; the 

 latter stout in aU species except pagodella. Harpe with 

 costa strongly sclerotized but not produced at apex. 

 Anellus V- or U-shaped with long lateral arms. Aedea- 

 gus simple; penis armed with a single, more or less 

 twisted, fattened bladelike cornutus (except dorsima- 

 cula). Vinculum stout, short or but slightly longer 

 than broad, with truncate, broad terminal margin. 



Female genitaUa with bursa and ductus bursae 

 simple, unsclerotized except for a narrow band along 

 ventral margin of genital opening; with or without 

 signum; when present, the latter developed as a small, 

 scobinate, cup-shaped plate; ductus bursae shorter 

 than bm-sa; ductus seminalis from bursa at its junction 

 with ductus bursae. 



The. genus is very close to and difficult to distinguish 

 from Sematoneura. It is characterized chiefly by the 

 bent condition of vein 6 of forewing. In Sematoneura 

 this vein is always perfectly straight and remote from 

 8-9 at base. In Hypsipyla 10 is also normally from the 

 cell and there is frequent stalking of 4 and 5 of hind 

 wing, neither of these conditions occurs in Sematoneura; 

 but the venation is so individually variable in Hypsipyla 

 that it cannot be trusted.

Forewing grayish fuscous shaded (especially on lower 

 half of wing) with dull rust-red; veins outlined in black; 

 antemedial pale line narrow, incomplete, roimded out- 

 ward at middle and indented at vein lb, bordered out- 

 wardly by a narrow, discontinuous, black line; beyond 

 this in median area Isetween top of cell and vein lb, an 

 expanded faint whitish patch; some faint whitish dust- 

 ing also in the middle-outer area between the veins; 

 subterminal line faint, indicated chiefly by the intensi- 

 fied black streaks bordering it inwardly on the veins, 

 sinuate, deeply notched at lower fold; discal spots 

 obsolete; terminal black dots between the vein ends 

 distinct. Hind wing hyaline white with a fuscous 

 shade along costa, some fuscous shading on the vein 

 ends and a narrow fuscous line along termen. Alar 

 expanse, 23^5 mm. 



Male genitalia with uncus rather abruptly narrowed 

 beyond its broad base, the apex narrowly roimded; 

 apical hook of gnathos narrow, short; paired horns of 

 transtilla curving outward (away from each other); 

 vinculum distinctly broader than long, its terminal 

 margin very broad and but slightly convex, nearly 

 straight. Eighth abdominal segment of male simple. 

 Female genitalia with signum.

Generally distributed throughout tropical America 

 wherever its food plants occvu-. 



A native American species close to and superficially 

 similar to the Indina H. robusta; but with different male 

 and female genitalia. It is apparently of some eco- 

 nomic importance in the West Indies and South America 

 as a pest of mahogany and the Cedrela species. Like 

 many borers it varies greatly in size, and the venation 

 is more than ordinarily unstable even for a phycitid. 

 Vein 10 of forewing may be from the cell, separated 

 from, closely approximate or connate with 8-9 or some- 

 times shortly stalked with them. Veins 4 and 5 may 

 be anything from approximate towards base to shortly 

 stalked. Vein 6 is always slightly bent towards base
