NYMPHALIXAE: THE (iENUS BRENTIIIS. 579 



nearly the width of the oxtremu l)ase of the antennae; a little longer than the abdomen, 

 consisting- of thirty-three to thirty-live joints, of -which the last ten or eleven form a 

 strongly depressed, broad, ovate club, at least live times as broad as the stalk and not 

 more than twice as long as broad, the first two joints rapidly enlarging, and the last 

 five entering into the diminution of size; extremity l)roadly rounded, interrupted by 

 the little conical projection formed by the apical joint; furnished beneath with a median 

 carina, which extends far on the stalk. Palpi very long and rather slender, Ijarely 

 twice as long as the eye, curving slightly forward, the apical joint not more than 

 one-tenth the length of the penultimate, furnished above and beloAv, the middle joint 

 nearly as much as the others, with a rather thin fringe of forward reaching hairs of 

 nearly uniform length, all in a general vertical plane; and below, exteriorly, -with a 

 a roAv of erect, scattered, long and slender hairs, pi'ojecting laterally a very little. 



Prothoracic lobes not large, almost cylindrical, straight, uniform, the ends equal, 

 as long as high, and four times as broad as long. Patagia very small, some-v\iiat 

 tumid, very broad, almost circular, the posterior portion projecting as a short, trian- 

 gular, l)luntly rounded lobe, the whole not half so long again as broad. 



Fore wiuys (39:7) twice as long as broad, the costal margin very slightly and 

 broadly convex, the apical angle rounded oft'; outer margin a little convex, gener- 

 ally regular, sometimes a little protuberant about the lower subcostal nervule, the 

 general direction of the border being at an angle of about 45° -with the costal margin ; 

 inner border straight or very slightly concave, the outer angle rounded. First supe- 

 rior subcostal nervule arising shortly before the apex of the cell ; the others at nearly 

 equal distances apart, the third about midway betw^een the apex of the cell and the 

 outer margin ; second inferior subcostal nervule arising about one-third way down the 

 cell ; the latter considerably less than half as long as the wangs and from two to 

 three times as long as broad. Median nervure connected with the vein closing the 

 cell by its last branch, nearly half as far bej'ond the second divarication of the ner- 

 vure as that is beyond the first. 



Hintl wings wath the costal border rather largely shouldered and well rounded next 

 the base, beyond nearly straight or very slightly convex ; outer border very I'cgu- 

 larly rounded and pretty full, both angles rounded ofT; the inner margin not very 

 greatly nor abruptly expanded next the base, beyond nearly straight or slightly con- 

 vex, with no apical excision or emargination. Precostal nervure directed straight 

 upward, sometimes bent slightly outward at the summit; second subcostal nervule 

 originating at a little distance ((J), or scarcely at all ( 5 ), beyond the base of the 

 first ; cell closed. Last branch of median nervure curved considerably toward the 

 lowest subcostal nervule, beyond the cell. No androconia. 



Fore legs small, cylindrical, fringed with long hairs on the outer side, much more 

 thinly in the female than in the male; tibiae less ((J) or more ($) than one-half the 

 length of the hind tibiae ; tarsi almost as long as the tibiae, consisting either of a single 

 joint with a produced conical apex and an apical spur ($)•■, or of five joints, the 

 length of the first fully three-fifths of the whole, the second, third and fourth dimin- 

 ishing regularly in size, the fourth and fifth equal; furnished beneath, at the apex of 

 all the joints but the last, with a pair of short, slender, minute spines, in a naked 

 field; but there are no intermediate spines, nor an j' along the lo-^ver portion of the 

 sides of the basal joint ( $ ) ; middle tibiae scarcely shorter than the hind pair, fur- 

 nished on either side beneath with a row of not very frequent, long, and very slender, 

 somewhat spreading spines, the terminal ones developing into very long, and very 

 slender, tapering spurs ; also above and on the sides -n'ith numerous similar shorter 

 spines ii'regularly placed. Tarsi, beneath, with four nearly equidistant rows of short, 

 very slender spines, the terminal ones of each joint a little longer than the others; 

 above, abundantly sprinkled with numerous very short, delicate spines, ii'regularly dis- 

 posed, but apparently with a tendency to form longitudinal rows. Claws small, mod- 

 erately stout, considerably curved, tapering to a blunt point; paronychia bifid, the 

 anterior lobe as long as the cla-\vs, very slender, scarcely tapering, finely pointed, 

 curving but little; posterior lobe minute, slender, short; pulvillus broader than long.
