terminal dots faint, more or less confluent. Hind wing 

 (of male) translucent white, the veins pale brown in 

 outer area; a fine brown line along termen. Alar 

 expanse, 26-30 mm. 



Male genitalia with apical process of gnathos a 

 single, narrow, flattened hook with notched apex. 



Type locality: St. Jean Maroni, French Guiana 

 (type in BM). 



Food plant: Unknown. 



Distribution: French Guiana: Cayenne, St. Jean 

 Maroni. Brazil: Parand, Taperinha. 



The foregoing description based on three males in 

 the National Museum. What I take to be a female from 

 Cayenne in the Janse Collection is also before me. It 

 differs from the males in having broader forewing, the 

 antemedial line outwardly oblique from costa, the 

 subterminal line more distinct, and the hind wing a 

 glossy brown. The bursa is large, as long as ductus 

 bursae; the signuin a single straight line of rather sharp, 

 spinelike thorns. 



Genus 27: Hyalospila 



[Venational division D. Forewing with 11 veins; 4 and 5 closely 

 approximate for some distance from cell. Hind wing with all 

 veins very long; cell less than one-third the length of wing. 

 TranstUla complete, developed as a narrow, slightly arched band.] 



27. Genus Hyalospila Ragonot 



Hyalospila Ragonot, Nouv. Gen. p. 11, 1888; Monograph, pt. 1, 

 p. 168, 1893. (Type of genus: Hyalospila stictoneurella 

 Ragonot.) 



Tongue well developed. Antenna of male simple; 

 shaft very weakly pubescent. Labial palpus upcurved, 

 reaching above vertex; slender; segment 3 as long as or a 

 trifle longer than 2, acuminate. Maxillary palpus sub- 

 squamous (scaling more or less dilated). Forewing 

 smooth; 11 veins; vein 2 from before lower outer angle 

 of cell; 3 from the angle, shortly separated from 4 at 

 base; 4 and 5 closely approximate for some distance 

 from cell (not stalked as stated by Ragonot); 6 from 

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

 not more (usually less) than half the length of 8; 10 

 from the cell, approximate to the stalk of 8-9; male 

 without costal fold. Hind wing with vein 2 from before 

 lower outer angle of cell; 3 from the angle, closely 

 approximate to the stalk of 4-5; 4 and 5 stalked for 

 about half their lengths; 7 and 8 contiguous or very 

 weakly anastomosed for not over half their lengths 

 beyond cell; all veins very long; cell less than one-third 

 the length of wing; discocellular vein curved. Eighth 

 abdominal segment of male with a pair of ventrolateral 

 hair tufts. 



Male genitalia with apical process of gnathos an 

 elongate, slender hook with slightly notched apex. 

 Uncus triangulate. Transtilla complete, a simple, nar- 

 row, slightly arched band. Harpe narrow; costa 

 stA-ongly sclerotized throughout and projecting slightly 



at apex; otherwise simple. Anellus a small shield with 

 long, slender lateral arms. Aedeagus simple; penis 

 armed with numerous fine scobinations or one or more 

 clusters of slender spines. 



Female genitalia with signa present, consisting of a 

 single cluster of bluntly pointed thorns, frequently 

 surrounded by fine scobinations or strongly pigmented 

 granulations; bursa various, strongly granulate over 

 much of one side, weakly sclerotized towards or at junc- 

 tion with bursa, more or less finely scobinate or (except 

 for signum patch) smooth; ductus bursae weakly 

 sclerotized towards genital opening or with genital 

 opening simple; ductus seminalis from bursa near 

 junction of bursa and ductus bursae. 



A distinct, easily recognized genus apparently 

 limited to tropical America. The species also are easily 

 identified by their genitalia. It is difficult to place 

 Hyalospila satisfactorily in any linear arrangement for 

 it partakes of the characters of two distinct groups. On 

 male genitalia, especially its complete bridgelike trans- 

 tilla, it should go with the genera of the main Acrobasis- 

 Myelois stem having this organ well developed, while 

 on other characters, general habitus, and the long veins 

 and short cell of hind wing it seems more closely related 

 to genera of the Piesmopoda group. 



109. Hyalospila stictoneurella Ragonot 

 Figures 44, 226, 703 



Hyalospila stictoneurella Ragonot, Nouv. Gen., p. 11, 1888; 

 Monograph, pt.l, p. 169, 1893. 



Forewing purplish brown, a narrow ocherous-white 

 band along costa, extending from costa to upper vein of 

 cell and showing under magnification a scattered pow- 

 dering of reddish scales; the extreme costal edge at its 

 middle, darkened; the veins more or less streaked with 

 black scaling; antemedial line indistinct, indicated by 

 an oblique blackish streak from costa, a small whitish 

 dot in ceD and another on vein lb, each followed by a 

 black dot; subterminal line faint but distinguishable, 

 close to and parallel with termen, not dentate; discal 

 dots at end of cell confluent, blackish brown. Hind 

 wing semitransparent whitish; the veins brown, a brown 

 border along costa and a fine brown line along termen. 

 Alar expanse, 19-22 mm. 



Male genitalia with transtilla a short, slightly arched 

 bridge, somewhat wider than that of any other known 

 species and with a minute, pointed projection at middle. 

 Penis armed with three small clusters of fine, short 

 spines. Vinculum but slightly longer than greatest 

 width, tapering to its rather broad, rounded terminal 

 margin. 



Female genitalia with bursa unsclerotized, weakly 

 scobinate in the area about the signum; the latter a 

 small patch of small, thornlike spines (fig. 703a) ; ductus 

 bursae considerably longer than bursa, weakly sclero- 

 tized for a short distance from genital opening and with 

 a patch of scobinations at its middle, otherwise mem- 

 branous and simple.
