in the paper: The puparia of the Sciomyzinae I have seen are all 
of rather common shape, cylindrical and elongated oval, a little 
attenuated at each end. At the posterior end are two small pro- 
truding and diverging spiracular knobs, and below them a number 
of more or less pronounced teeth. The colour is paler or darker 
reddish. Only the puparium of Bischofia simplex is relatively short 
and thus more oval, and it is of a darker colour, dark or blackish 
brown. The surface of the puparia is smooth, only in Ditaenia 
grisescens I found girdles of small spines, and the puparium of 
Sciomyza dorsata is somewhat corrugated transversely. The puparia 
of the Tetanocerinae are, what is interesting to State, somewhat dif- 
ferent from those of the Sciomyzinae, and they are more or less 
of the sfTape known for Tetanocera and Sepedon. They are thus 
less cylindrical, but have generally the ventral side rather arched, 
the dorsal more flattened, and generally the posterior end with the 
spiracular knobs is curved a little dorsally; the surface is less smooth 
than in the Sciomyzinae, it is more or less corrugated transversely 
and along the sides there are one or more longitudinal rows of 
elongated oblique or more roundish impressions which may be more 
or less pronounced. (The puparium of Tetanocera ferruginea, of which 
I have seen a great number, may for the rest vary rather much, 
both as regards the shape and the ornament of the surface, yet 
preserving a certain characteristic aspect.) The surface is cha- 
racteristically duil and also the colour is characteristic, greyish brown 
tending towards slightly greenish, sometimes almost aeneous. The 
puparia of Heptopteryx brevipennis and Limnia unguicornis are, how- 
ever, reddish and have the posterior end not or almost not recurved; 
in Hedroneura rufa and Sepedon sphegeus the colour is rather pale, 
whitish or yellowish. I shall finally note that in accordance with 
de Meijere’s statement I found no outer prothoracal spiracular tubes 
in any Sciomyzid pupa. 
The places in which these puparia are found together with what 
is known of the larvæ of Tetanocera and Sepedon would seem to 
make it probable that the larvæ are phytophagous or feed on 
decaying vegetable matter, perhaps also being carnivorous on small 
objects, but anything definite is not brought forward; on the other 
hånd it may, after the observation of Mercier, now be taken as 
proved that Salticella fasciata is parasitical on snails. As noticed,
