helix has been proved to occur in Pommerania; it is distributed over the entire palaearctic region, with 
exception of the extreme north. Recently it has been found by Marechal in Belgium in Province of Liege. 
It is often very frequent, whilst the $$ of crenulella are only known from very few localities, with the ex¬ 
ception of south of the Alps. Seiler, as already remarked, found a similar, though not so extreme mal¬ 
distribution in the proportion of and 9$ a l so i n 1 he Solenobiae and Talaeporia tubulosa according to the 
more northerly or southerly locality. According to Ale. Nageli, Zurich, the number of ova laid in the casing 
is very small, only 14—18 in each sac. He had found helix in large numbers at Glattfelden (Zurich). The 
larvae hibernated in their casings. The casings of the species, especially of the form helix, of which I have 
a large number in my collection, vary very considerably, both in colour and superficial appearance, a.' also 
of the internal dimensions. According to the nature of the soil, they can be dark black-brown, as for instance in 
specimens from Regensburg, the bavarian Jura and Strigow, or they can be rusty coloured, as for instance 
at Ruffach in Alsace or they can show all shadings of pale to dark grey, as in the Tyrol and Tessin, the smooth 
or rough outer surface depends on the finer or coarser grains of sand or earth that the larvae use as their 
material. — Klimesch found the larvae chiefly on Anthyllis vulneraria, Teucrium chamaedrys and Scabiosa 
columbaria, mining the leaves like a Goleophora larva, generally only feeding at night, lying hidden during t e 
day on the ground under the food plant. It devours a round hole in the Epidermis and then feeds on the 
Parenchyma around same. — v. Linstow and others have held **) crenulella Brd. and helix Sieb. to be two 
separate species, basing themselves on the semi-geometric not very successful illustration of Bruand which 
especially in the antennae shows distinct variation, crenulella from Aix en Provence is illustrated m - lonogi.

the Tyrol, Bolzano in the Zeitschrift Wiss. Zool. 17, PI. XXVIII. This question cannot however be decided 
from these illustrations, because as v. Siebold has pointed out the descriptions of the antennae that Bruaxd 
gave, are better than his illustration and correspond exactly to those mentioned by Claus. — crenulella flies

larva hibernates once, according to Naufock; the $ is easily distinguishable from that of sapho and majorella 
by the distinctly prominent yellow colour of the wool of the head and anus. In the other species these are 
of greyish hue. Time of emergence and period of flight are different from majorella sapho and sunentella, 
which emerge and fly from 5 to 9 in the morning. According to Klimesch the larva has a preference foi e
