GELECHIA. 1038 
ternella, a fat sluggish larva, feeds in the young shoots of Sfed- 
laria wliginosa, which, from the presence of the larva, assume a 
peculiar knobbed and contorted appearance; that of G. b7/ractella 
feeds in the seeds of the Conyza squarrosa, which it by some means 
unites together, forming a firm, almost impenetrable substance, 
within which it is completely sheltered from all the vicissitudes of 
the weather; that of G. Cerealella (according to Réaumur) feeds 
in the interior of grains of barley and wheat, entering the grain 
immediately it is hatched, and remaining within till it has un- 
dergone its transformations, and only coming out in the per- 
fect state; that of G. sudocellea (in other respects the most aber- 
rant species of the genus) feeds on the flowers of the marjoram 
(Origanum vulgare), of which it constructs a case, thereby re- 
sembling the Coleophore. The species that feed in buds and 
shoots are of course mostly in the larva state in spring and the 
beginning of summer, those that feed in or on leaves are met 
with in summer and autumn, and those that feed on seeds do so 
in the autumn and winter. The perfect insects are successively 
to be met with from April to October, and several species are 
known to hybernate. 
It is not easy to tabulate the species of this genus; the best [ 
have been able to accomplish is as follows :— 
a. Anterior wings not rounded at the apex, 
6. Anterior wings unicolorous. Species 1, 2. 
6 b. Anterior wings with spots. Species 3, 4. 
aa. Anterior wings rounded at the apex. 
c. Posterior wings broader than the anterior wings. Species 5-69. 
ec. Posterior wings as narrow as, or narrower than the anterior 
wings. 
d. Anterior wings with no sharp markings in the cilia. 
e. Anterior wings without markings. Species 70, 71. 
ee. Anterior wings with a single white fascia. Species 72-74. 
eee. Anterior wings with one or more dark spots on the dise. 
Species 75-89. 
eeee. Anterior wings with oblique silvery streaks from the 
costa. Species 90-92. 
eeece. Anterior wings with longitudinal dark streaks (like a 
Coleophora). Species 93, 94. 
dd. Anterior wings with sharp markings in the apical cilia. 
Species 95. 
1. cinerella, Linn. F. S. 1445 (1761); Fab.; Treit.; Step.;
