1919. 

 Zamagiria deia Dyar, Ins. Insc. Menstr., vol. 7, p. 46, 1919 (new 



synonymy). 

 Zamagiria striella Dyar, Ins. Insc. Menstr., vol. 7, p. 47, 1919 



(new synonymy). 



Aigrette of male maxillary palpus dull white. 



Forewing pale gray, the overall tint shading from 

 grayish white to very pale bluish gray (in fresh reared 

 examples); costal border slightly darker; the patch be- 

 tween scale ridge and antemedial Hne reddish brown; 

 similar reddish brown scaling spread over basal area 

 bordering inner margin and frequently blotching the 

 median area over vein lb and the lower fold (especially 

 on the males) ; also some scattering of reddish brown 

 streaking on veins 3 and 4 for a very short distance from 

 cell; black scale ridge more or less complete; on several 

 males a black or black and red-brown streak along vein 

 lb from scale ridge to base of wing; transverse lines 

 faint, the outer blacldsh border of the antemedial and 

 the inner dark border of subterminal more or less inter- 

 rupted (more so on males than females); discal dots 

 separated, black, the lower one shghtly enlarged; a 

 row of 5 or 6 small black dots along termen. Hind 

 wing semihyaline white; a dark line along terminal mar- 

 gin and some faint darkening of the veins. Alar ex- 

 panse, 15-22 mm. 



Male genitalia similar to those of Jraterna except: 

 Costa of harpe convex but not decidedly humped; an- 

 nellus inverted ; ^ penis with cornutus a single, very 

 stout, long spine (over two-thirds as long as aedeagus) 

 surrounded by a cluster of small granulations. 



Female genitalia with a finely spined plate (signum) 

 near junction of bursa and ductus bursae, and a strongly 

 sclerotized lateral patch in bursa near its anterior end; 

 ductus bursae with a sclerotized plate occupying most 

 of its length, the posterior end of the plate folded over 

 into triangulate ventral lips. 



Type localities: Honda, Colombia {laidion, in BM) ; 

 Chejel, Guatemala {deia and striella, in USNM). 



Food plants: Achras sapota, Mimusops emarginata, 

 Eriobotyra japonica (larvae feeding on leaves and 

 flowers) . 



Distribution: United States: Florida, Key West 

 (Apr., May), Aliami (Jan., Dec). Guatemala: Chejel 

 (June). PanamX: Porto Bello (Feb.). Colombia: 

 Honda. Brazil: Castro {Parand) Obidos (Amazon re- 

 gion, Sept.), Vi50sa {Minas Geraes, Sept.). Bolivia: 

 "East Bolivia" ("Aug.-Oct., T. Steinbach"). 



Hitherto laidion has been recognized only from female 

 examples. A reared series in the National Museum 

 from Florida has enabled us to associate the sexes and 

 has established the synonymy of deia and striella, both 

 described from males. Dyar's type of striella is merely 

 an extreme example of a common color variant with 



' This structure seems more like a transtilla than an anellus; 

 for its straight posterior margin lies between the costal bases of 

 the harpes, and it could be interpreted as a transtilla or com- 

 bination of transtilla and anellus, except that in other species of 

 the genus there is no trace of even the vestiges of a true transtilla. 



more or less black streaking on the base of vein lb of 

 forewing. The reared Florida specimens have also 

 given us the host records cited above. 



197. Zamagiria ipsetona Dyar 



Figure 768 



Zamagiria ipsetona Dyar, Ins. Insc. Menstr., vol. 7, p. 47, 1919. 



Forewing gray, more heavily marked with black than 

 in preceding species; the blackish streakings on the 

 veins (2 to 6 in this species) longer and stronger; lower 

 discal spot elongated into a black dash; dark dashes 

 (reddish brown) on the veins in outer area following the 

 faint subterminal line; the black scale ridge not con- 

 tinuous; antemedial line sinuate and nearly vertical; 

 the whitish areas limited to a pale oval patch surround- 

 ing the black-streaked veins and discal dots and a faint 

 shade preceding the black scale ridge; the usual red- 

 brown scaling limited to the patch between scale ridge 

 and antemedial line and weak shadings between some 

 of the veins in postmedian area. Hind wing translu- 

 cent white; a narrow dark shade along costa and a 

 blackish line along termen; veins appreciably darkened. 

 Alar expanse, 23-24 mm. 



Female genitalia with two elongate spined plates in 

 bursa; another more weakly spined plate at junction of 

 bursa and ductus bursae; from the junction a scJeroti- 

 zation extends along one side of bursa for about four- 

 fifths of its length; ductus bursae very short, strongly 

 sclerotized towards genital opening, the plate folded 

 over at the opening into ventrolateral lips. Eighth- 

 segment collar completely fused ventrally. 



Type locality: Juan Vinas, Costa Rica (type in 

 USNM). 



Food plant : Unknown. 



Represented by three females from the type locality 

 (Feb., June). The male is unknovra. 



49. Genus Anegcephalesis Dyar 



Anegcephalesis Dyar, Ins. Insc. Menstr., vol. 5, p. 46, 1917. — 

 Heinrich, Ins. Insc. Menstr., vol. 5, p. 48, 1917 (larva). 

 (Type of genus: Anegcephalesis cathaereles Dyar.) 



Characters of Zamagiria except: Maxillary palpus 

 minute, subsquamous in both sexes. Forewing with 

 veins 4 and 5 connate or very shortly stalked. Hind 

 wing with cell longer (slightly less than one-third the 

 length of wing) . 



The genus is very close to Zamagiria but its separa- 

 tion seems to be justified by the differences in the male 

 maxillary palpi and the longer cell of hind wing. The 

 venational differences noted above (between veins 4 and 

 4 of forewing) may be only a specific character. Dyar 

 distinguished Anegcephalesis from Zamagiria on the 

 difference in maxillary palpi, but mistook the appressed 

 scale tuft from frons for that organ. This scale tuft is 

 present and equally well developed in Zamagiria and 

 Anegcephalesis.
