Type localities: Napa, Calif, {alatella, in AMNH, 

 ex Rutgers); California (rectistrigella, in Paris Mus.); 

 Pecos, N. Mex. (Jragilella, in USNM); San Diego, 

 Calif, (piazzella, in USNM). 



Food plant: Unknown. 



Distribution: California, Clarkville ( June) , Monache 

 Meadows (July), Napa, Placerville (May), San Diego 

 (Mar., Aug.), San Francisco (Apr.); Utah, Bellevue 

 (Apr.); Colorado, Gunnison County (near Almont, 

 July) ; New Mexico, Fort Wingate (June, July) , Jemez 

 Springs (June), Pecos (June). 



An individually variable species in color and to some 

 extent in male genitalia. The actual holotypes of 

 alatella, fragilella, and piazzella seem different enough; 

 but there are all intergrades among them in a series 

 from any given locality. Indeed the two cotypes of 

 alatella from Napa, Calif. (aUke in color and markings) 

 show considerable variation in details of male genitalia 

 (width of the sclerotized costa of harpe, shape of 

 transtilla, and spacing of the apical prongs of gnathos) . 

 The genitalia of the cotype from Napa (in USNM, fig. 

 193) shows an extreme of variation. The other cotype 

 (in AMNH, ex Rutgers, the actual holotype) has 

 genitalia identical with those of piazzella shown in 

 figure 195. At most, the Dyar names represent forms 

 or varieties, but not species or local races. 



19. Genus Anypsipyla Dyar 



Anypsipyla Dyar, Proc. U. S. Nat. Mus., vol. 47, p. 327, 1914. 

 (Type of genus: Anypsipyla univitella Dyar.) 



Tongue well developed. Antenna of male shortly 

 cihate, the cUia no longer than width of shaft; of female 

 pubescent. Labial palpus obliquely uptm-ned, reach- 

 ing slightly above vertex; third segment about as long 

 as second, acuminate. MaxiUary palpus very slightly 

 dilated with scales at apex (subsquamous) . Forewing 

 smooth; 11 veins; vein 2 from before but close to lower 

 outer angle of cell; 3 from the angle, approximate to 

 2 ; 4 and 5 stalked for approximately half their lengths, 

 approximate (rarely connate) to 3 at base; 6 from below 

 upper angle of cell, straight; 8 and 9 stalked for about 

 half their lengths; 10 from the cell, at base closely 

 approximate to or connate with stalk of 8-9, thence 

 divergent; male with short narrow costal fold. Hind 

 wing with vein 2 from well before lower outer angle of 

 cell; vein 3 from the stalk of 4-5; 4 and 5 long stalked; 

 7 and 8 anastomosed beyond cell for appreciably more 

 than half their lengths; cell about half the length of 

 wing; discocellular vein curved. Eight abdominal 

 segment of male with a single pair of ventrolateral hair 

 tufts. 



Male genitalia with apical projection of gnathos an 

 elongate hook with slightly notched apex. Uncus sub- 

 triangulate (hoodlike). Transtilla complete, strongly 

 arched. Harpe with costa strongly sclerotized through- 

 out and projecting at apex beyond apex of cucullus; 

 otherwise simple. Anellus a narrow band with slender 

 lateral arms. Aedeagus simple; penis with some 

 weakly sclerotized wrinklings, otherwise unarmed. 



Female genitalia with or without signa, if present, in 

 the form of a row of very small, weak, thornlike spines ; 

 bursa very finely scobinate, ductus bursae considerably 

 longer than bursa, simple; genital opening simple; 

 ductus seminalis from anterior (terminal) end of bursa. 



A distinct genus with one tropical American species. 



76. Anypsipyla univitella Dyar 

 FiGTiRES 39, 196, 679 



Anypsipyla univitella Dyar, Proc. U. S. Nat. Mus., vol. 47, p. 327, 

 1914. 



Forewing fuscous gray with a broad white subcostal 

 streak extending from near base to apex and touching 

 costa near base and at apex; a black streak along mid- 

 costal edge and on fresh specimens a fine black line along 

 lower vein of ceU and some faint black streaking on the 

 outer veins; a fine powdering of reddish scales on the 

 white subcostal stripe; discal dots faint or absent; trans- 

 verse lines obsolete. Hind wing hyaline white with a 

 smoky tint along costa and at apex and a fine dark line 

 along termen. Alar expanse, 20-32 mm. 



Male genitalia with terminal margin of uncus rather 

 broadly round; apical projection of costa of harpe blunt; 

 transtilla truncately arched. Female genitalia as given 

 for the genus. The signa are usually absent and when 

 present consist of from 2 to 10 very weak spines. 



Type locality: Corozal, Canal Zone, Panamd (type 

 in USNM). 



Food plants: Cassia brasiliensis, Samanea samdn 

 (larva feeding in pods), Pacae (larva in fruit). 



Distribution: Cuba: Victoria de las Tunas, San 

 Bias (Trinidad Mts., May). Mexico: Colima (May, 

 Nov.). Guatemala: Cayuga (Apr.), Quirigud (Mar.).

Probably generally distributed in tropical America, 

 where its host plants occiu*. 



20. Apomyelois, new genus 



Type of genus: Dioryctria bistriatella Hulst. 



Tongue well developed. Antenna simple and pubes- 

 cent on both sexes. Labial palpus upturned, slender, 

 reaching to slightly above vertex; third segment slightly 

 shorter than second, acuminate. Maxillary palpus fili- 

 form. Forewing smooth; 11 veins; vein 2 from well 

 before lower outer angle of cell; 3 from the angle; 4 and 

 5 stalked for slightly less than half their lengths, the 

 stalk separated from 3 at base; 6 from below upper 

 angle of cell, straight; 8 and 9 long stalked (for over 

 two-thirds their lengths) ; 10 from the stalk of 8-9 ; male 

 without costal fold. Hind wing with vein 2 from weU 

 before lower outer angle of ceU; veia 3 from the angle; 

 4 and 5 stalked for two-thirds of their length, the stalk 

 connate with 3; 7 and 8 anastomosed beyond cell for 

 about half their lengths (the anastomoses slightly longer 

 than the free part of vein 8) ; cell a trifle more than half 

 the length of the wing; discocellular vein curved. Eighth
