Genus IX. HELIODINES. 
Hrnropinas, n. g. Chrysoesthia p., Hiib. Weophora p., Treit. ; 
Dup. LHlachista p., Zell. 
Capilli levigati, frons obtusa. Antenne setacese, corporis fere longi- 
tudine, articulo basali devi, clavato. Palpi labiales parvi, crassius- 
culi, acuminati. Haustellum mediocre. Abdomen crassiusculum, 
breve. Ale longissime ciliate, anteriores elongate, metallice macu- 
late, posteriores lineari-lanceolate ; anteriores: cellula discoidalis 
postice dilatata, vix clausa; cellula secundaria nul/a; vena apicalis 
furcata, ramo altero in apicem, altero in marginem posticum exeunte, 
infra eam venee quatuor; subdorsalis simplew ; submediana non in- 
crassata; posteriores: vena mediana trifida; vena discoidalis sim- 
plex ; vena apicalis simplex. 
Head smooth, the forehead obtuse. Antenne setaceous, almost as 
long as the body, the basal joint short, clavate. Labial palpi smaid, 
rather thick, acuminate. Tongue of moderate length. Abdomen rather 
thick, short. Wings with very long cilia, the anterior elongate, with 
metallic spots, the posterior linear-lanceolate. In the anterior wings 
the discoidal cell is expanded posteriorly, and hardly closed; there is 
no secondary cell; the furcate apical vein terminates in the apex and 
in the hinder margin, below it are four veins; the subdorsal is simple ; 
the submedian not thickened; in the posterior wings the median vein 
is trifid, the discoidal vein is sémple, and the apical vein is simple. 
This genus only contains a single species, of which no speci- 
mens have been taken in this country for probably the last thirty 
years. According to the observations of 'lischer and Heeger, the 
larvee feed in June, rather gregariously, on Chenopodium, Atri- 
plex, etc., drawing several leaves together by a number of silken 
threads ; the perfect insect appears in July, and is frequently again 
met with in May after hybernation. 
It is hardly necessary to add that the Linnean habitat, “in 
Mali foliis subcutanea,” is founded on a misconception that De. 
Geer’s figure of a Lithocolletis, to which he refers, represents this 
insect; subsequent authors have copied Linneus in indicating 
apple as the food of the larva, without verifying his observation, 
or noticing the evident cause of his error.
