340 Dr. T. A. Chapman’s notes on Micro-Lepidoptera 
another and neither attempted to injure the other in any 
way. As judged by the sizes of their heads, there were 
at least three sizes of larvee on October 21st, which with 
the newly-hatched one makes four sizes ; but there is little 
doubt that there would be one or two intermediate sizes 
between the young larve and the smallest seen at this 
date. The intestinal contents, so far as they are visible 
through the larva, were in one instance green, in two 
others brownish. Occasionally a good end view of the 
larva is seen, and then its angularity (on cross section) is 
very evident, the spaces between the double rows of 
processes being hollow and the processes placed on the 
angles of a flat, raised surface. None of the drawings I 
have bring out this peculiarity quite satisfactorily. 
These larve preserve also the long antennz; these 
have an elegant curvature, and are placed on the head so 
as to look, as it moves from side to side, ridiculously 
like the horns on a Hereford ox—the proportionate 
length of horn to head being not very different in the 
two cases. 
The moss on which these larvee thus happened to be 
reared was named for me by the Rev. A. Ley as 
Hypnum prelongwm, a common species. ‘There were 
also present, though it was doubtful if these were 
growing, two other common species, Hypnum tamari- 
scinum and swartzii, and possibly others. 
I must admit that I was nearly as much astonished at 
finding the full-grown larva retain the peculiar structure 
of the young larva, as I was when I first saw the newly- 
hatched larva. Having so few and wishing very much to 
obtain the pupa if possible, I did not sacrifice any of 
these, for closer examination; but one that died, of 
2°5 mm. long, though not quite satisfactory, gave me a 
good view of the abdominal legs and ball appendages ; 
the head was unfortunately retracted and could not be 
satisfactorily made out. ‘All these larvae perished during 
the winter, and left no trace, except some remains that 
make a rather poor slide. 
In 1893 I prepared eight jars with various mosses and 
succeeded in having plenty of eggs laid in them, but for 
some reason or other the young larve, which hatched 
abundantly, appeared to have all perished, until I was 
pleased and surprised early in November to observe two 
full-grown larvee in one of the jars.
