observed gnawing the leaves of Sfellaria nemorum 
in shady places among woods about the end of 
August. The transformation took place on the 
stems of the plants, to which the pupz adhere by 
the tail, just like the chrysalids of butterflies. The 
fly develops about the middle of September.” 
Zeller, P. C. (Dipterologische Beitrage, 2te Abth., Isis, 
1842, pp. 807-809.—Limnobia distinctissima, 
Wied., Meig.). Zeller refers to Boie, but deems it 
useful to give a more detailed description. He 
found the larve near Glogau (Silesia) in the 
spring, on leaves of Anemone nemorosa; im some 
places they occurred abundantly. ‘The larvex 
generally remain on the underside of the leaves, 
and by gnawing, make holes in them. About the 
middle of May they leave their food plants, fasten 
themselves upon grass-blades, leaves, etc., and 
usually pupate on the very next day; the pupw 
show a remarkable analogy to those of the genus 
Pterophorus (Lepidoptera). They hang fastened 
by the tail of the larva-skin, which is not stripped 
off the last three or four segments. Zeller gives a 
more detailed description of the larva and pupa 
than his predecessors. It results from the pre- 
ceding statements that the larva of Cyl. distunctis- 
sima occurs on various phanerogamous plants— 
Viola, Stellaria, and Anemone, and that it has, at 
least m some localities, two generations, one in 
the spring (Schellenberg, Zeller) and the other in 
autumn (Boie). 
3. The supposed larva of Triogma. 
G. de Rossi (Ent. Nachr. 1876, pp. 30, 31) describes a 
peculiar larva which he had discovered in woods, 
upon a species of moss (Hypnum), among which 
it was hidden. Hesucceeded in rearing the pupa, 
but unfortunately the pupa produced only an 
Ichneumon. As he had not made a description of 
the larva before its pupation, he published an 
account of it from memory. In this account I 
recognised the larva of a Tipulid belonging to the 
Section Cylindrotomina. A short article, which I 
published about it in the same periodical (Hnt.
