190 . GROTE & ROBINSON. 



HEUKETES, n. g. 



The head is small; eyes globose ; labial palpi closely scaled, divari- 

 cate, passing beyond the wide " front." Antennae very short, seta- 

 ceous, thickly scaled and flexuous at apices. Primaries with the costa 

 slightly rounded, a little depressed before the acuminate apices. Ex- 

 ternal margin long and oblique ; internal angle I'ounded, as is also the 

 margin. Discal cell large ; nervules straight, short and equidistant. 

 Thorax wide and short, compact and globose, but small and square in 

 front. Abdomen ( 9 ) as wide as the thorax, and a little longer than 

 internal margin of the secondaries. Legs rather stout, closely scaled, 

 with intermixed longer hair. 



A little genus of peculiarly tortriciform appearance, as seen by the 

 shape of the primaries with their acuminated apices, before which the 

 costa is depressed, as in Tortrix. The large discal cell and equidistant 

 straight nervules are tortriciform characters. From all our United 

 States genera distinct by the very short antennae, with their very pe- 

 culiar apical conformation. It comes neai"er to Dr. Packard's genus 

 Tortricidia. 



Heuretes picticornis, 11. s. 



9 . — Thorax and primaries ferruginous brown, the latter with a 

 purplish shade determinate along external margin. No markings ; 

 the nervules indicated. Secondaries pale, contrasting forcibly with 

 primaries. Fringes concolorous with the wings, rather long and heavy. 

 Beneath, the costal edge at base, front and anterior legs within are 

 brighter colored, orange ferruginous. Wings beneath pale, immacu- 

 late, nervules indicated. Abdomen concolorous with the pale seconda- 

 ries. The brighter colored anterior tibiae are obsoletely shaded with 

 blackish outwardly, as are the tarsi. Middle and hind pair of legs 

 pale, hind tarsi shaded with ferruginous. 



Antennae pale testaceous, bent at the tips, before which is a blackish 

 shade, which gives them the peculiar appearance of being indented. 

 or of presenting a more unusual structure than, under the glass, they 

 are seen to possess.

The outwardly whitish ovoid cocoonet accompanies the single speci- 

 men we have of this species. It is, as usual, of thin, compact texture, 

 and is flattened beneath, where, from the impression left on the cocoo- 

 net. it must have rested on the rib of a leaf aiofc. A large opening 

 at one end shows where the insect escaped, and from its clean cut,
