HIMERA PENNARIA. 
Plate CIX, fig. 4. 
Note on the Hgg, and some Peculiarity of Structure 
im the Larva, of Himera pennarva.—Harly last 
December (1880) Mr. D’Urban put into my hands an 
ash twig gathered by a laudable butcher’s boy at 
Hxeter, whose attention had been caught by the 
appearance of a batch of eges near the tip. I ought 
at once to have known to what species these eggs 
belonged, but, luckily, did not recognise them ; other- 
wise, pr obably, I should not have cared for nen and 
should have missed making an observation which, I 
think, deserves some notice. 
There were just 151 eggs, laid in nine rows, 
parallel with the stem of the twig, in most beautifully 
compact and regular order, the whole mass measuring 
rather more than three-eighths of an inch in length 
and about three-sixteenths in width, and firmly stuck 
together, and to the bark of the twig, by an abundant 
supply of shining hght red cement. The shape of 
the ege is cylindrical, set upright on end, about one- 
thirtieth of an inch in height and one- forty- fifth of an 
ich in transverse measurement; the top is rounded ; 
sometimes the cylindrical shape becomes somewhat 
hexagonal, from being squeezed in so closely on all 
sides; the shell is glossy, with a shght roughness 
round the top; the colour pale green; towards 
spring this changes to a pale reddish-brown, and 
again four or five days before the larva emerges to a 
blackish hue. The batch of empty egg-shells looks 
like a piece of Lilliputian honeycomb. 
The first larva was hatched on the 13th of April, 
1881, and the last that came out about a fortnight 
later. Some died in the ego; I think, however, that 
the larvee at large were delayed this year by the cold 
nights, and that none, probably, were hatched till the
