The genus is quite distinct from any other on male 

 genitalia. Its closest relatives seem to be Praedonula 

 and Hyalospila. On many genitalic characters it re- 

 sembles the following genus (Gabinius), especially in 

 the development of uncus and harpe; but separates 

 from it on hind wing venation, especially the length 

 and position of vein 2.

p. 48, 1919. 



Forewing pale brown shaded with red and blackish 

 scales; the costal border white sparsely dusted with 

 red scales and with medial costal edge reddish; ante- 

 medial line obscure except on lower half, far out, oblique 

 from costa to cell and below ceU inwardly concave, 

 white, bordered outwardly on costa by a faint reddish 

 streak; some black scaling along basal half of vein lb; 

 a distinct black dot on lower vein of cell at middle, and 

 on the vein lb on the outer edge of the antemedial line; 

 subterminal line sinuous, bordered inwardly by a nar- 

 row, dark brownish shade and followed in outer area 

 (especially towards apex) by some white dusting; discal 

 dots distinct, separated, black, the lower one somewhat 

 elongated ; an irregular black line along terminal mar- 

 gin reaching almost to apex. Hind wings translucent, 

 smoky white, darkening outwardly; the veins slightly 

 darkened and a fine dark line along termen. Alar ex- 

 panse, 19.5-20 mm. 



Male genitalia with no trace of sclerotized gnathos; 

 aedeagus with apex bluntly pointed, bearing a line of 

 short, coarse spines along its edge. Female genitalia 

 with ductus bursae weakly sclerotized near genital open- 

 ing; sclerotized plates behind genital opening narrow, 

 bladelike; sclerotization of bursa near ductus seminalis 

 slight. 



Type localities: Mount Pods (Juan Vinas), Costa 

 Rica (burdettella, in USNM) ; Juan Vinas (semproniella, 

 in USNM). 



Food plant: Unknown. 



Distribution: Costa Eica: Juan Vinas (Jan.), 

 Mount Pods (May). Guatemala: Volcdn Santa Maria 

 (July). 



Dyar estabUshed the above synonynay of Schaus' 

 species. The genitalia of their male types are identical. 



175. Peadus dissitus, new species 

 Figures 270, 755 



Sinular to burdettellus in color and markings except 

 for a distinct whitish longitudinal shade through the 

 cell of forewing and a stronger accentuation of the black 

 scaling; a thin black streak from base along half the 

 lower fold and a similar, shorter black streak on it just 

 before the subterminal line; outer margin of antemedian 

 line indicated by strong black dots on upper and lower 



veins of cell and on vein lb; inner dark margin of sub- 

 terminal line broadened by black streak. Alar expanse, 

 20-22 mm. 



Male genitalia with gnathos a weakly sclerotized 

 transverse band; aedeagus with an expanded, flangelike, 

 densely and finely spined apex. Other minor diflfer- 

 ences from burdettella (especially in the shapes of 

 cucvllus and the projecting part of sacculus of the harpe) 

 are shown in the figures. Female genitalia with ductus 

 bursae much shorter than in burdettella, strongly sclero- 

 tized; sclerotized plates behind genital opening broad- 

 ened at their bases; sclerotization of bursa near 

 ductus seminalis appreciably stronger. 



Type locality: "S. E. Brazil" [Parand?] (type in 

 BM; paratypes in BM and USNM, 61334). 



Food plant: Unknown. 



Described from male type and three male and three 

 female paratypes from the type locality, "E. D. Jones, 

 1920—303". 



176. Peadus subaquilellus (Ragonot), new combination 

 Figure 753 



Hyalospila subaquilella Ragonot, Nouv. Gen., p. 11, 1888; Mono- 

 graph pt. 1, p. 170, 1893; pt. 2, p. 38, fig. 24, 1901. 



This species is known only from the female type. A 

 drawing of its genitalia made by Clarke is figured. I 

 have seen nothing to match Eagonot's figure and de- 

 scription which indicate a form with dark reddish brown 

 forewing shaded somewhat with black at base and on 

 the costa but without other markings; hind wing 

 "transparent," smoky, the veins and terminal margin 

 appreciably darkened. Alar expanse, 20 mm. 



The generic placement is tentative, pending discovery 

 of a male. The female genitaHa are not typical, lacking 

 the sclerotized plates behind genital opening, but seem 

 to indicate a closer relationship to Peadus than to any 

 other genus. 



Type locality: "Cerro Zunil," Guatemala (type in 

 BM). 



Food plant: Unknown. 



Genus 43 : Gabinius 



[Venational division B. Forewing with veins 4 and 5 connate; 

 2 from near lower outer angle of cell. Hind wing with 2 from 

 close to lower outer angle of cell; 3 from the stalk of 4r-5; cell less 

 than one-third the length of wing. Uncus reduced, weakly 

 sclerotized, triangulate. Tegumen greatly reduced but with 

 strong, projecting lateral arms. TranstUla incomplete. Harpe 

 reduced; apex of costa spined. Vinculum short, stout.] 



43. Gabinius, new genus 



Type of genus: Promylea paulsoni Eagonot. 



Tongue well developed. Antenna of male simple, 

 pubescent. Labial palpus upturned, reaching above 

 vertex; second segment somewhat broadly scaled; third 

 segment shorter than second, bluntly acuminate. Max- 

 illary palpus squamous. Forewing smooth; 11 veins; 

 vein 2 from before but near lower outer angle of cell, 

 nearly as close to 3 at base as 3 is to 4; 3 from the angle;
